This book was released on 1991 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polychlorinated terphenyls (PCTs) are structurally similar to polychlorinated biphenyls (PCBs) and have been used in analogous applications. Reports of the environmental occurrence of PCTs are rare. PCT formulations Aroclor 5432 and 5460 were recently detected in sediments and shellfish from several tributaries of the Chesapeake Bay. Maximum sediment concentrations of Aroclor 5432 and 5460 were 250 000 ?g/kg and 19 000 ?g/kg (dry-weight basis), respectively. Aroclor 5460, which contains terphenyls with a high degree of chlorination, was detected in sediments near outfalls at 8 of the 26 facilities examined in this study. No significant burdens of Aroclor 5460 were observed in shellfish collected in the vicinity of the contaminated sites. The less-chlorinated Aroclor 5432, although encountered less frequently, was of particular interest because of its propensity to accumulate in biota. Indigenous oysters contained up to 35 000 ?g/kg of Aroclor 5432. This value is equivalent to 6300 ?g/kg on a wet-weight basis, exceeding the current limit for PCBs in shellfish destined for human consumption. Limited information is available regarding the toxicity of PCTs. Only one published report of the environmental occurrence of Aroclor 5432 is known to exist. Analytical difficulties in distinguishing Aroclor 5432 from PCBs may have contributed to the paucity of observations.

PCB was found in some products particularly in those composed of paper. PCT was absent from all the products tested except one sample of corrugated cardboard. PCB and PCT were found in most samples of garbage"--Abstract, page i.

This book was released on 2012-12-06 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polychlorinated biphenyls (PCBs) have been produced commercially since be fore 1930. They proved to be highly versatile mixtures and their uses continued to expand during the early 1970's even after the unanticipated world-wide en vironmental contamination had been discovered (Jensen et aI. , 1969; Koeman et aI. , 1969). Over 600,000 metric-tons were produced and/or used in the U. S. during this time and it is estimated that worldwide production totaled about 1,200,000 metric-tons (Table 1). With low acute toxicities (Fishbein, 1974), these mixtures were considered gen erally biologically inactive even though industrial exposure had demonstrated he patic and dermatological effects (Fishbein, 1974; Hansen, 1987). Thus, use and disposal were not carefully monitored and it is estimated that one-third of the world-wide production of PCBs has been released into the global environment (Table 1). Table 1.
