PESTAB. Toxaphene was identified by multicolumn electron-capture GLC in some of the environmental samples analyzed for chlorinated hydrocarbons in the Upper Bay area of Maryland. The rainwater samples from the Fort Smallwood collection site contained residues nearly identical to the toxaphene standard at levels of 280 ppt (parts per trillion) on Aug. 28-Sep. 4, 170 ppt Sep. 4-28, 44 ppt Sep. 28-Oct. 1, and 86 ppt Oct. 16. One rainwater sample from further inland (Sollers Point) also contained toxaphene at 220 ppt. One storm sewer content sample collected still further inland contained toxaphene at 13 ppt and a zooplankton sample collected near Sollers Point on July 8, 1974 contained toxaphene at 1.7 ppm (wet weight). The residue patterns in the latter samples did not match the standard as closely as did the rainwater samples. The PCB levels were low in the samples examined, and thus did not mask the presence of toxaphene.
