Wellington Laboratories Polar Bears

PCB Analytical Method Solutions

The complex nature of commercial polychlorinated biphenyl (PCB) mixtures is well documented.

The practice of analyzing for marker PCBs (congeners that are most prevalent in technical mixtures) and WHO PCBs (congeners that exhibit “dioxin-like” toxicological activity) has become routine practice in analytical laboratories.  Congener specific analyses are also very important since commercial PCBs can vary in composition on a lot to lot basis and can change once they age in the environment.

Wellington offers method sets, which include calibration kits and support solutions, for the GCMS analysis of PCBs by the following methods:

  • U.S. EPA Method 1668C
  • U.S. EPA Method 1668
  • Environment Canada Method 1/RM/31
  • BS-EN 1948-4:2010 (previous draft method = prCEN/TS 1948-4)

The electrophilic chlorination of biphenyl leads to complex mixtures of chlorobiphenyl (PCB) congeners ranging from monochloro- up to decachloro-biphenyl. Although 209 PCB congeners are theoretically possible, only about 150 are found in industrial mixtures and have ended up in the environment.

Certain PCB congeners are considered more toxic than others and are termed ‘dioxin-like’. For this reason there are analytical methods that target only these ‘dioxin-like’ PCBs, while other methods focus on the major PCB congeners in the industrial mixtures. In addition, there are methods that address both groups of PCB congeners.

Wellington has designed, prepared, and offers a number of sets of calibration kits and support solutions for the analysis of individual PCB congeners. 

WP-CVS

This set of solutions is to be used for the analysis of the 12 dioxin-like PCB congeners by HRGC/HRMS.

EPA Method 1668C

This series of calibration solutions, and corresponding support solutions, were prepared to be used according to U.S. EPA Method 1668, Revision C.

EPA Method 1668

This calibration kit and support solutions were designed and prepared to be used with the Draft version (March, 1997) of U.S. EPA Method 1668 which is still popular with some laboratories.

EC-9605-CVS

Environment Canada Method 1/RM/31 is a HRGC/LRMS method for PCB analysis and these solutions were prepared to be used with this method.

P48-W-CVS and P48-M-CVS

European Standard Method EN 1948-4 is to be used for analysis of the 12 ‘dioxin-like’ PCB congeners and the 6 ‘marker’ PCB congeners in stationary source emissions. These two calibration kits, and their support solutions, were prepared for this method.

WM48-CVS

This calibration set is a combination of P48-W-CVS and P48-M-CVS.

 

We also offer solutions to test the resolution of common HRGC columns for 2,3,7,8-TCDD and 2,3,7,8-TCDF and set retention time windows for PCDD and PCDF congener groups.

Denmark was the first country to ban PFAS from food packaging

NATIVE AND MASS LABELLED PFAS SOLUTIONS/MIXTURES

 

Denmark will be the first country to ban PFAS Chemicals, which have been linked to cancer, elevated cholesterol and decreased fertility. 

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)
  •                   …and more

These solutions can be found on pages 141 – 159 of Wellington Laboratories’ current catalogue.
