摘要
The effects of various mercury chloride (HgCl2) concentrations associated with bottom sediments on mercury accumulation in chironomid larvae and the modifications of morphofunctional parameters (mortality, growth, and structure of the mouth apparatus) have been studied. It was shown that, upon exposure, the larvae accumulated mercury in amounts exceeding its sediment concentrations. The mortality rate and metamorphosis duration increased with an increase in metal concentrations, while the animal size remained unaffected. Among all investigated morphological structures, the antennae were the most heavily effected.
