The only data comparable to these are for the ringed seals of Admiralty Inlet (Muir et al., 1988); total chlordanes in those samples were at concentrations generally similar to the sum of chlordane components listed in Table 6, and dieldrin concentrations in the two sample suites were also similar.
Chemical analyses of their blubber have detected PCBs, DDT, chlordane and toxaphene -- at some of the highest levels over recorded in a living organism.
Substances with endocrine effects include chlordane; DDT/DDE; dieldrin; hexachlor-benzene; lead; mercury; PCBs; dioxins; and toxaphene.
The need for an effective biological control for white grubs was intensified in 1969 by the removal of the chemical chlordane from the market.
Another frequently found fish contaminant and probable cancer-causer is chlordane, which has been widely used to control termites.
2008) has also been found for residential termite treatment before 1988 (a surrogate for the insecticide chlordane).
The advisory is based on elevated levels of various toxins, including mercury, PCBs, DDT, chlordane, pesticides and lead.
These 12 priority POPs include 8 organo-chlorine pesticides: aldrin, chlordane, dichloro-diphenyl-trichloroethane (DDT), dieldrin, endrin, heptachlor, mirex and toxaphene; two industrial chemicals: hexachlorobenzene (HCB) and the polychlorinated biphenyl (PCB) group; and two groups of industrial by-products: dioxins and furans.
Among those covered are polybrominated biphenyls (PBB), polychlorinated biphenyls (PCB) and terphenyls (PCT) and tris (2,3 dibromopropyl) phosphate, several forms of asbestos, 2,4,5-T, aldrin, chlordane, DDT, dieldrin, heptachlor, hexachlorobenzene, lindane, mercury compounds, pentachlorophenol and methyl-parathion.
six pesticides (DDT, chlordane, HCB, toxaphene, aldrin, and dieldrinc):
Palos Verdes is no longer "the" hot spot with respect to DDT or PCB's; mussels near marinas and harbors are the most contaminated with PCB's and chlordane. Levels of organochlorines at distant urban stations, such as Point Dume, are now nearly equivalent to those at remote sites.
Nine of the 12 (aldrin, endrin, dieldrin, chlordane, DDT, heptachlor, hexachlorobenzene, mirex, and toxaphene) are pesticides, all of which have been targeted for elimination by nongovernmental organizations (NGOs) around the world since the early 1980s as part of Pesticide Action Network (PAN) International's Dirty Dozen campaign.
