Abstract
The bioavailability of 14C-lambda-cyhalothrin and its bioconcentration by larvae of the aquatic insect Chironomus riparius was studied in laboratory sediment–water systems. Ten different sediments with a range of physico-chemical characteristics were investigated. The chemical was applied to sediment slurries and fourth instar C. riparius were exposed in the test system for 48 h. The distribution of the chemical between the sediment, water and organism phases was determined. In addition, the bioconcentration of 14C-lambda-cyhalothrin by C. riparius in a water-only test system was determined.Keywords
