Bioaccumulation and Elimination of Waterborne Mercury in the Midge Larvae, Chironomus riparius Meigen (Diptera: Chironomidae). Bull Environ Contam Toxicol 89, 245–250 (2012). https://doi.org/10.1007/s00128-012-0674-z0007-48611432-0800http://hdl.handle.net/10400.8/14742Here, mercury kinetics and behavioural effects in the midge larvae under a water-only exposure were assessed. Uptake and elimination of waterborne mercury were described by using a one-compartment kinetic model. Results show that midges were able to readily accumulate the heavy metal (BCF = 450), presenting a fast uptake, up to 13.1 lg Hg g of animal-1 at the end of the exposure period. Elimination was slow, with c.a. 39 % of the mercury in larvae being depurated after 48 h in clean medium. Behaviour did not present differences upon exposure or elimination, but a trend to increase ventilation was noticed during the exposure period.engToxicokineticsOnline biomonitoringMercuric chlorideWater only exposurejournal article10.1007/s00128-012-0674-z
