Chlorophenols in lake bottom sediments : a retrospective study of drinking water contamination.
Lake and brook bottom sediments were analyzed for chlorophenols to provide historical data of exposure assessment, after the water intake plant of a Finnish village had been found to be contaminated in 1987, and subsequently elevated non-Hodgkin lymphoma risk was detected.
Highly elevated 2,3,4,6tetrachlorophenol and pentachlorophenol levels were found in all four lake sediment cores investigated.
The distribution was uneven with much higher concentrations in the estuary, in contrast to PCB compounds which were more evenly distributed within the basin.
