The United States Environmental Protection Agency (US EPA) recently posted new Method 1628, which allows for the detection of all 209 PCB congeners in wastewater. This new method utilizes low-resolution gas chromatography-mass spectrometry with select 13C-labeled PCB congeners as isotope dilution quantification standards. Note this method is not yet approved at 40 CFR Part 136. CIL offers a full suite of standards to support this new method.

INDUSTRIAL CHEMICALS

6PPD is an antioxidant and antiozonant that is used as an additive in rubber tires to help protect against degradation. When 6PPD reacts with ozone it transforms into several byproducts, including 6PPD-quinone, which has recently been determined to be highly toxic to coho salmon. 2-Chloroethanol is the byproduct of ethylene oxide reacting with chloride, and is considered a hazardous substance and toxic at high concentrations.

PESTICIDE AND PESTICIDE METABOLITE STANDARDS
 
The need for crop protection chemicals continues unabated, and CIL vigorously supports creation of standards for both parent compounds and metabolites.  A recent emphasis on pyrethroid metabolites results in the addition of 14 new pyrethroid metabolites, with an emphasis on 2,3,5,6-Tetrafluoro-substituted metabolites of pyrethroids such as tefluthrin, profluthrin, tetramethylfluthrin, renofluthrin, transfluthrin, and others that may inhibit detoxification of monooxygenases.
