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

Contamination by Persistent Organochlorines in Small Cetaceans from Hong Kong Coastal Waters

“…In general, concentrations in cetaceans are apparently higher than in seals. The residue levels of TCPMeOH in hump-backed dolphins and ®nless porpoises from Hong Kong waters are apparently higher than those found in Caspian seals, Baikal seals (Watanabe et al, in press), harp seals, whales and harbour seals from the St. Lawrence River, Canada (Jarman et al, 1992) and Puget Sound, USA (Walker et al, 1989). With regard to other coastal areas in developed European countries, such as southern North Sea, Dutch Wadden Sea (de Boer et al, 1996), the concentration of TCPMeOH, however, was lower.…”

DDT, A Potential Source of Environmental Tris(4-chlorophenyl)methane and Tris(4-chlorophenyl)methanol

“…TCPM-OH was first discovered in harbor seals from the northwestern United States (I), and its occurrence was correlated with most other organochlorine contaminants like DDT, PCBs, and dieldrin. TCPM-OH seems to be present in the environment since more than 40 years ago (3). Both compounds have now also been detected in human milk (4).…”

SULFONATION OF ENVIRONMENTAL CHEMICALS AND THEIR METABOLITES IN THE POLAR BEAR (Ursus maritimus)

“…TCPM is a globally distributed organochlorine compound of uncertain origin, which was reported in human adipose tissue (Minh et al, 2000). Polar bear liver contains 4000 to 6800 ppb lipid weight TCPM, the highest levels recorded for this compound in all species studied (Jarman et al, 1992). TCPM is a potent androgen receptor antagonist in vitro (Schrader and Cooke, 2002).…”
