Native Certified Reference Standards for L-PFUdS & L-PFTrDS

In early 2020 the european Parliament and the Council of the european Union released new requirements for the analysis of per- and polyfluoroalkyl sunbstances (PFAS) in water intended for human consumption (5813/20).  Unfortunately this amendment to Council Directive 98/83/EC included perfluoroalkanesulfonates that were not comercailly available.  In response to this, Wellington Laboratories synthesized, purified, characterised and prepared accurate Certified Reference Standards of the required substances: sodium perfluoro-1-undecanesulfonate (L-PFUdS) and sodium perfluoro-1-tridecanesulfonate (L-PFTrDS).  Wellington Laboratories have also prepared a native solution/mixture (EU-5813-NSS) that contains all of the PFAS listed in the drinking water directive (5813/20) for your convenience.  This solution/mixture can be used in conjunction with two of our exisiting mass-labelled PFAS mixtures to easily prepare a calibration set for quantitation:

Suggested Extraction Standard Mixture:  MPFAC-C-ES

Suggested Injection Standard mixture:    MPFAC-C-IS

Perfluorinated Compounds (PFCs)

Perfluorinated compounds (PFCs) are an emerging class of environmental contaminants. Their unique properties create a host of analytical challenges that require the use of native and mass-labelled standards for the generation of accurate data. The most notable PFCs include PFOS (perfluorooctanesulfonate) and PFOA (perfluorooctanoic acid) and Wellington currently offers multiple mass-labelled standards for these compounds to meet your analytical needs. In fact, Wellington offers a large selection of native and mass-labelled per- and poly-fluorinated compounds, including:

Perfluoroalkylcarboxylic Acids (PFCAs)
Perfluoroalkylsulfonates (PFASs)
Perfluorooctanesulfonamides (FOSAs)
Perfluorooctanesulfonamidoethanols (FOSEs)
Perfluorooctanesulfonamidoacetic acids (FOSAAs)
Telomer Alcohols (FTOHs)
Telomer Acids (FTAs)
Telomer Sulfonates (FTSs)
Perfluoroalkylphosphonic acids (PFAPAs)
Perfluoroalkylphosphinic acids (PFPi’s)

These products can be found on Pages 141 - 159 of the current Wellington Laboratories Catalogue.

Perfluorinated Compounds (PFCs) Certified Reference Standards

Wellington Laboratories started to synthesize perfluorinated compounds in 2004 and since then has regularly added new native and mass-labelled standards to their inventory.   In the current Wellington Laboratories catalogue, pages 141 - 159 yiou will find individual standards of the following groups of compounds including, in most cases, mass-labelled analogues as well as some useful soultions/mixtures:

PFC-C-CVS Calibration Set and Support Solutions

Perfluoroalkanesulfonates (PFASs)

Perfluoroalkylcarboxylic acide (PFCAs)

Perfluorooctanesulfonamides (FOSAs)

Perfluorooctanesulfonamidoethanols (FOSEs)

Perfluorooctanesulfonamidoacetic (FOSAAs)

Fluorinated Telomer Alcohols (FTOHs)

Fluorinated Telomer Acids (FTAs)

SPECIAL SESSIONS

From Good Science to Good Risk Management

Environmental Image

The goal of this session is to illustrate how good science leads to good regulatory decisions, and the ultimate outcome of that process, the reduction of health and environmental risks associated with organohalogens.   Risk managers initially depend on scientific researchers to flag a need to address a specific environmental problem.  Very basic to this determination is toxicological information, and environmental and human health monitoring and analysis to highlight exposure scenarios.  Risk managers, then, depend on research to quantify the problem so that proportional action can be determined, to provide direction on how to address the problem, and also to highlight specific management measures and factors which should be taken into account to guide the management process.  Fundamental parts of this determination include the fine-tuning of analytical techniques, epidemiological research, and information on chemical transformation and physical transport of these substances which enhance our predictive abilities in determining exposure.  Research into environmental remediation techniques further expands the range of potential risk management choices.

It is proposed that this session highlight examples involving organohalogens, illustrating exactly how this process has worked, from research to regulation, and how it has contributed to good risk management decisions.

Possible sub-topics of this session include:

– Analytical innovation and the development of accurate and affordable sampling methods to provide direction in the need for and focus of risk management.

 – The development of more complex, fully integrated assessment tools to better inform risk assessment, and subsequently, risk management decisions.

–  Broad approaches to assessing risks and implications for risk management: How to maximize assessment efficiencies which in turn leads to more efficient risk management.

– The need for risk management adaptation prompted by new occurrences or new information, i.e., the re-circulation of dioxins and other POPs in Arctic regions due to global warming of frozen deposits, and determination of management approaches.

 – Global collaboration in the management of organohalogens based on the dissemination of toxicological information which in turn has prompted risk management decision and action by governments around the word, culminating in a global effort to reduce the presence of these substances.

Bio- and Phytoremediation for Clean-Up of Persistent Organic Pollutants

 

Plants Image

This session will concentrate on nature-based remediation options for persistent organic pollutants. Microorganisms indeed are very ‘creative’ in using all kinds of organic molecules as a source of energy. After the Deepwater Horizon oil spill in the Gulf of Mexico, for example, it was found that most of the energy-rich hydrocarbon compounds that spilled into the ocean were ‘consumed’ by microbes, thus resolving the problem. Halogenated compounds, such a PCBs, contain much less energy than hydrocarbon compounds. Nevertheless, microbes can still use them. For PFAS, the situation is not clear yet, but in any case different from PCBs. Carbon-fluorine bonds are much stronger and thus more difficult to break than carbon-chlorine bonds. Moreover, during evolution, microbes were in contact with naturally occurring chlorinated compounds. It is therefore not surprising that when they encounter human-made chlorinated pollutants like PCBs, they don’t consider them as totally foreign. However, naturally occurring fluorinated molecules are rare, certainly those with more than one fluorine atom. Since most human-made PFAS contain many fluorine atoms, it is not evident, but not excluded, that specific microbes (or consortia of microbes) can cope with it.

 

Many microbes developed in close interactions with plants, either in the rhizosphere and phyllosphere or even inside the plants. Since, due to the presence of many plant exudates, the numbers of microbes in the rhizosphere are 10 and often more than 100 times higher than in the bulk soil, co-metabolization of human-made pollutants can be important. Plant thus can increase the degradation potential of pollutants, which has been demonstrated in many cases. Moreover, due to the evapotranspiration of water, plants act like ‘pumps’ and thus attract pollutants to their root zone. Plant further ‘catch’ plenty of gaseous and particulate pollutants from the atmosphere which allows the phyllosphere microbes to cope with them.

Environmentally Persistent Free Radicals (EPFRs) as a new class of pollutant

Pollution Image

In this specific session a discussion platform is suggested to the researchers worldwide to talk about “Environmental Persistent Free Radicals (EPFRs)” as new class of pollutants. The more than decadal research performed in superfund research program (SRP) at LSU about formation and toxicological consequences of resonantly stabilized radicals (lately known as Environmentally Persistent Free Radicals – EPFRs) reveals the fact that EPFRs are significant contributor on overall potency of particulate matter (PM).

It is now well-known fact that EPFRs are deriving mostly from incomplete combustion of organic materials; they are typically formed on particulate matter through interaction with aromatic hydrocarbons, catalyzed by transition metal oxides, and produce reactive oxygen species (ROS) in biological media that may initiate oxidative stress. The origin and nature of EPFRs, studied for a long time in superfund research program (SRP) at LSU since 2007, was expanded and dispersed over many research laboratories worldwide. To illustrate the importance placed on these EPFR compounds by the research community and the society at large, it is interesting to note the explosion of literature related to the topics of “EFPR” or “environmentally persistent free radicals” in the last five decades, especially with the onset of the ground-breaking research initiated at LSU in the early 2000’s.

A brief listing of the large distribution of EPFRs in different environmental samples can be outlined.

  • environmental particulates PM5,
  • contaminated soil and sediment samples,
  • Superfund soil samples in the USA,
  • samples from plants’ phytometric measurements
  • EPFRs on engineered nanoparticles.
  • EPFRs on biochars, carbonaceous adsorbents etc.

A comprehensive description of formation, characteristics, and applications of surface bound EPFRs is continuously presented in number of high-level publications.

There is also a particular interest toward formation of reactive oxygen species (ROS) from interaction of EPFRs with biological media, from photochemical processes occurring in the atmosphere such as a wide range of ROSs appear in the gas phase of secondary organic aerosols as very unstable intermediate products, such as hydrogen peroxide, organic peroxides, diacyl peroxide, peroxynitrite, etc., and in the particulate phase. A significant and a thorough research was reported recently about the particle bound – reactive oxygen species, PB-ROS, including neutral intermediate organics, among radicals associated with PM.

We expect an exciting discussion of detection/identification of EPFRs from combustion systems, waste incinerators, automobile combustion engines, refineries, biomass burning and many other thermal treatment sites.

Wildland and Wildland-Urban Interface (WUI) Firefighting 

 

- Current Knowledge and New Studies

Fire Image

While exposures to municipal firefighters and cancer outcomes have been studied repeatedly, much less is known about the exposures and health effects in wildland and WUI firefighters. This is despite the marked increase in wildland fires in many countries throughout the world.  This session will bring together an international group of researchers with current wildland/WUI studies to share existing results and study protocols. Members of the fire service will be invited to provide input on study design and recommendations for dissemination of study results and suggestions for and/or implementation of interventions to reduce exposures.

Sessions will cover:  

Fire effluents determination (measurements)

  • Fire effluents (WUI)
  • Personal (wristband, sensors)
  • Biomarkers of exposure (urine, blood, etc.)
  • Air/Soil/Water
  • Drones/Satelites etc.

Contamination sources

  • Workplace (PPE)
  • Firefighting techniques (foams)

Health

  • Biomonitoring for toxicity (blood/urine etc.)
  • Cancers
  • Diseases (Cardiovascular etc.)
  • Mental health

Regulation/Guidance/Best practice

  • Cancer registry
  • Best practice/minimising exposure to toxicants
  • Preventative health screening
  • Presumptive legislation

Global Monitoring of POPs

Water Image

This goal of this session is to provide a better insight in monitoring data of persistent organic pollutants (POPs) worldwide. Since the start of the Stockholm Convention this list of POPs has gradually increased. A global monitoring program was established to follow POP concentrations in matrices such as human milk, air, and water around the world with the aim to assess temporal and spatial trends and in that way follow the effectiveness of the implementation of measures taken under the Convention. Results of such monitoring programs are coming available more and more and worthwhile to show and discuss. In addition to the global monitoring plan, results of comparable studies for other matrices are most welcome to complement this session. These studies should be geographical and temporal trend studies carried out in specific regions, such as the Arctic or Antarctica, or on various continents. Results of POP monitoring in all types of matrices, such as fish, sediment, air (active or passive air monitoring), water or human matrices are welcome. In addition to the traditional organohalogen compounds such as PCBs, organochlorine pesticides or dioxin-like compounds, results on relatively ‘new’ POPs, such as PFAS, brominated flame retardants and chlorinated paraffins are of specific interest. Also, results on some POPs on which until now relatively little information has been gathered such as kepone and toxaphene are welcome.

What are PFAS?

More than 4730 compounds(1) belong to the group of PFAS (which stands for per- and polyfluoroalkyl substances) that have been produced since the 1940s. Since these compounds do not originate from nature, the global pollution is the result of human activity. All PFAS are of anthropogenic origin. PFAS are "forever chemicals", chemicals that are very persistent in the environment and in the human body.

General structure of perand polyfluoroalkyl substances (PFAS)

PFAS are organic compounds with a carbon chain in which hydrogen is substituted by fluorine. The carbon-fluorine bond is very strong which makes them “virtually indestructable“. The molecular structure of the PFAS provides them with non-sticky and tensid-like characteristics (because of their hydrophobic, lipophobic chain + hydrophilic head).There are polymers and non-polymers. Typical polymers are fluoropolymers, side-chain flurorinated polymers and perfluoropolyethers. Typical non-polymers are perfluoroalkyl acids (PFFFAs), perfluroalkane sulfonyl fluorides (PASF), perfluroalkyl iodides (PFAIs) and per- and polyfluroalkyl ether (PFPEs) based derivatives(2).
Perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) have been the most produced and studied of these chemicals.
To cut a long story short: there are many different substance groups that need to be analyzed!

Chemical Structure of PFAS

PFAS Circle of contaminated products

Where are PFAS used?

 

 They are commonly used because of their non-sticky and tensid-like properties for various purposes:

  • Textiles, textile coating, e.g., seat covers, carpets, outdoor clothing
  • Fire extinguisher foams
  • Food packaging, e.g., pizza cartons, paper cups
  • Paper finishing
  • Fibre coating
  • Cookware
  • Building material, e.g., water resistant lacquer
  • Further consumer products, such as: furniture, polishing and cleaning agents and creams

How do PFAS find their way into the environment and the human body?

Per- and polyfluoroalkyl substances (PFAS) have been manufactured for more than 80 years, but health effects were neglected for a long time. In September 2020, the European Food Safety Authority (EFSA) published a new health risk assessment related to the presence of PFAS in food(3). This is the first EFSA expert opinion in which, in addition to PFOA and PFOS, other PFAS were also included in the exposure assessment and health risk assessment.

PFAS are emitted into the environment by different pathways. For example, exhaust air from industrial sources can contain PFAS and thus are dispersed into nearby ground and water bodies. Rain and snow, for example, can eventually carry them from the air into the soil and surface waters. Particle accumulation can even cause them to travel long distances through the air. PFAS are therefore also found far from industrial production sites and human living areas, such as in sediments from the Bering Sea to the Arctic(4/5). Through volatilization from products (evaporation from carpets or home textiles treated with soil-repellent agents) or from waterproofing sprays, indoor air can also be contaminated.
Soils can also be directly contaminated, for example by firefighting foams. With the uptake of PFAS from contaminated soils and waters in vegetation and their accumulation in fish, these substances enter the human food chain. Consequently, humans absorb PFASs from the environment through food, water or air.
These "forever chemicals" also find their way into wastewater treatment facilities from household sources. They then enter surface waters via treated wastewater or remain in sewage sludge. The sewage sludge, in turn, can be used as fertilizer in agriculture, and then over time these chemicals eventually leach into the groundwater. Once there, some of the precursor compounds are transformed into the persistent PFAS.

The new special phase – CHROMABOND PFAS

Over the years many different PFAS were developed. Now, they are found in the environment (water, food, soil, animals and humans) and their problematic health effects come into play.The challenge is that current analytical methods are limited.To tackle this challenge, we developed a special phase for the enrichment of a broad range of PFAS which provides good reproducibility and high recovery rates.
This is possible due to the different interactions the sorbent combination offers. These interactions are recommended by DIN 38407-42, EPA 537.1 and 533 guidelines.

Our CHROMABOND PFAS is a polymer-based combination phase which contains a weak anion exchange functionality. The combination of different SPE phases makes it possible to use various interactions (dipole-dipole, ionic, hydrophobic, H-bond).

CHROMABOND PFAS provides several advantages

  • Solution for various PFAS substance classes
  • > 28 PFAS can be enriched
  • Sorbent retention mechanisms according to DIN 38407-42, EPA 537.1 and 533 guidelines
  • High capacity
  • High recovery rates

 This application note shows the reliable and successful determination of per- and polyfluoroalkyl substances (PFAS) from drinking water with an optimized SPE method. By using CHROMABOND PFAS it is possible to achieve high recovery rates for PFAS from drinking water with good reproducibility. By the combination of different SPE sorbents in a multi-layer column it is possible to use various interaction types like ionic, hydrophobic, hydrogen bonds and dipole-dipole for the enrichment of a broad spectrum of PFAS. In this way, a SPE method could be developed with the strength of several directives EPA 537.1, EPA 533 and DIN 38407‑42.

PFAS Plastics Pollution of our Seas and Oceans

Sea Polluted with Plastic Image

As the world wakes up to our environmental crisis it is important to note that every person living on our planet bears a responsibility for the world we have to live in.  Resources are limited and their supply is thretened by overuse and careless disregard for how resources are produced and sustained.  Whether it be our soil, air or water all are equally valuable is the quest to make our resources last and sustain our populations.  Global contamination of our seas and oceans is only the tip of the iceberg. Today's research scientists bear an enormous responsibility as they  endeavour to reduce and repair the impact we are having on our planet. 

Greyhound Chromatography supplies the world's leading scientists with analytical reference standards and materials to ensure testing of contaminants in our environment to the highest level.

Denmark just became the first country to ban PFAS from food packaging

Wellington Laboratories Logo Image

Denmark will be the first country to ban PFAS Chemicals, which have been linked to cancer, elevated cholesterol and decreased fertility, from food packaging, starting next year.   

PFAS substances, sometimes called "forever chemicals" because they don't break down in the environment, are used to repel grease and water in packaging for fatty and moist foods such as burgers and cakes.

What are PFAS chemicals, and what are they doing to our health?

"I do not want to accept the risk of harmful fluorinated substances (PFAS) migrating from the packaging and into our food. These substances represent such a health problem that we can no longer wait for the EU," Denmark's Food Minister Mogens Jensen said in a statement Monday.

PFAS chemicals are a family of potentially thousands of synthetic chemicals that are extremely persistent in the environment and in our bodies. PFAS is short for perfluoroalky and polyfluoroalkyl substances, and includes chemicals known as PFOS, PFOA and GenX.

They are all identified by signature elemental bonds of fluorine and carbon, which are extremely strong and what make it so difficult for these chemicals to disintegrate in the environment or in our bodies.

Under Denmark's new regulation, baking paper and microwave popcorn bags, for example, will be required to be manufactured without any PFAS.

"We congratulate Denmark on leading the way for healthier food and hope this will encourage similar action across the EU, the US and worldwide," said Arlene Blum of the Green Science Policy Institute and the Department of Chemistry at University of California, Berkeley.

FDA confirms PFAS chemicals are in the US food supply

"Given the potential for harm, we must ask if the convenience of water and grease resistance is worth risking our health," Blum said.

PFAS chemicals have been manufactured since the 1940s and can be found in Teflon nonstick products, stains and water repellants, paints, cleaning products, food packaging and firefighting foams.

These chemicals can easily migrate into the air, dust, food, soil and water. People can also be exposed to them through food packaging and industrial exposure.

A growing body of science has found that there are potential adverse health impacts associated with PFAS exposure, including liver damage, thyroid disease, decreased fertility, high cholesterol, obesity, hormone suppression and cancer.

In a statement, the Danish Veterinary and Food Administration said that the substances were very difficult to break down in the environment, and some of them accumulate in humans and animals.

The ban covers the use of PFAS compounds in food contact materials of cardboard and paper. The Danish government said it would continue to be possible to use recycled paper and paper for food packaging, but said PFAS compounds must be separated from the food with a barrier which ensures that they don't migrate into the food.

PFOS and PFOA are the two most-studied PFAS chemicals and have been identified as contaminants of emerging concern by the US Environmental Protection Agency.

PFOS was voluntarily phased out of production in the United States by 3M, the main manufacturer, starting in 2000. In 2006, PFOA began to be phased out as well. PFOA and PFOS are no longer manufactured or imported in the United States, but similar "replacement chemicals for PFOA and PFOS such as GenX, may be just as persistent," Susan M. Pinney, a professor in the Department of Environmental Health at the University of Cincinnati.

The European Food Safety Agency said it is reassessing the risks PFAS pose to human health and will report on its findings in the near future.

Wellington Laboratories offer a wide range of Certified Reference Standards for Testing and Analysis of Perfluorinated Compounds.

Perfluorinated Compounds (PFCs)

Per- and Polyfluoroalkyl Substances (PFAS) are an emerging class of environmental contaminants. Their unique properties create a host of analytical challenges that require the use of native and mass-labelled standards for the generation of accurate data.

The most notable PFAS include PFOS (perfluorooctanesulfonate) and PFOA (perfluorooctanoic acid) and Wellington currently offers multiple mass-labelled standards for these compounds to meet your analytical needs. In fact, Wellington offers a large selection of native and mass-labelled per- and poly-fluorinated compounds, including:

  •                   Perfluoroalkylcarboxylic Acids (PFCAs)
  •                   Perfluoroalkylsulfonates (PFASs)
  •                   Perfluorooctanesulfonamides (FOSAs)
  •                   Perfluorooctanesulfonamidoethanols (FOSEs)
  •                   Perfluorooctanesulfonamidoacetic acids (FOSAAs)
  •                   Telomer Alcohols (FTOHs)
  •                   Telomer Acids (FTAs)
  •                   Telomer Sulfonates (FTSs)
  •                   Perfluoroalkylphosphonic acids (PFAPAs)
  •                   Perfluoroalkylphosphinic acids (PFPi’s)

PFAS and Other Toxic Forever Chemicals in Drinking Water 

Images of Drinking Water

For over 30 years the European Union have worked tirelessly to protect the integrity of our drinking water.  EU officials have recently reached a provisional agreement to update the Union's 1998 Drinking Water Directive to tighten up the permissible limits allowed for both PFAS and several other drinking water contaminants, including bisphenol-A, microplastics, lead and chromium.   The at the time of writing the European Parliament and Council are still to formally approve the proposal. 

European drinking water standards currently far exceed the standards set in the United States but this is a changing picture as state by state new instances of contaminants are emerging.  Currently, the U.S. Environmental Protection Agency has only issued a nonenforceable health advisory of 70 ppt for PFOA, formerly used by DuPont to make Teflon, and PFOS, formerly an ingredient in 3M’s Scotchgard. Those compounds are no longer manufactured in the U.S., but they and other PFAS contaminate the drinking water for an estimated 110 million Americans. PFOA, PFOS and some other PFAS chemicals have been linked to cancer, thyroid disease, reproductive and immune system problems, and other health harms.

The european Parliament and the Council of the European Union have released new requirements for the analysis of per- and perfluoroalkyl substances (PFAS) in water intended for human consumption (5813/20).  This amendment to Council Directive 98/83/EC included perfluoroalkanesulfonates that are not commercially available.  In response to this Wellington Labroatories, Canada, is pleased to announce that its chemists have synthesized, purified, characterized and prepared accurate certified reference standards of the required substances: sodium perfluoro-1-undecanesulfonate (L-PFUds) and sodium perfluoro-1-tridecanesulfonate (L-PFTrDS).  Wellington Laboratories have also prepared a native solution/mixture (EU-5813-NSS) that contains all of the PFAS listed in the drinking water directive (5813/20) for your convenience.  This solution/mixture can be used in conjunction with two of Wellington's existing mass-labelled PFAS mixtures to easily prepare a calibration set for quantification.
