Effect of sediment contact and uptake mechanisms on accumulation of three chlorinated hydrocarbons in the midge, Chironomus riparius

The uptake of 5,5',6-trichlorobiphenyl, p,p'-DDE, and pentachlorophenol (PCP) from sediment by midge larval (Chironomus riparius) was investigated under 3 different conditions, namely direct contact with contaminated sediment, uptake by larvae screened from direct contact with contaminated...

Description
Summary:The uptake of 5,5',6-trichlorobiphenyl, p,p'-DDE, and pentachlorophenol (PCP) from sediment by midge larval (Chironomus riparius) was investigated under 3 different conditions, namely direct contact with contaminated sediment, uptake by larvae screened from direct contact with contaminated sediment, and passive uptake by dead larvae. With all 3 chemicals, significantly greater accumulation occurred in larvae in direct contact with the sediments. Although passive uptake also occurred, it was significant only in the case of PCB.
