Description
Summary:Commercial pentachlorophenol (PCP) contains significant quantities of tetrachlorophenol (TCP). The occurrence of tcp in environmental samples provides a chemical marker for pcp originating from commercial formulations. Negative chemical ionization mass spectrometry was used to examine such pcp formulations in a series of environmental and human samples. Pcp was determined by the ion current at m/z 267, pentachlorophenoxide. The ratio for jellyfish was 2.7, in human semen 4.1, and in human adipose tissue 15.5.
