Global distribution of tris(4-chlorophenyl)methanol in high trophic level birds and mammals

Article Abstract:

Researchers found high levels of TCP methanol in marine mammals and bird eggs located in the Arctic, Antarctica, Australia and the East and West Coasts of North America. In some cases the chemical was found in samples dating back to 1952. TCP methane was also found for the first time, in peregrine falcon eggs. The study indicates that methanol pollution from optically active polymers, agrochemicals and synthetic dye manufacture is quite extensive. Experimental procedures and results are described in detail.

Compound-specific carbon isotopic analysis of aroclors, clophens, kaneclors and phenoclors

Article Abstract:

Compound specific isotopic analysis (CSIA) of carbon isotopes has a wide variety of applications in the field of environmental chemistry. CSIA was used to evaluate the isotopic composition of carbon 13/carbon 12 in polychlorinated biphenyl mixtures of aroclor, clophen, kaneclor and phenoclor and results show a high predictability ration for the compounds.
