Among benthic aquatic insects there are taxa that grow abundant in sediments polluted with organic matter. Some of them also tolerate high levels of heavy metals. In this research short exposure and partial life cycle tests were carried out to evaluate the accumulation of mercury in Chironomus riparius Meigen larvae, pupal exuviae and adults from water enriched with HgCl/sub 2/. Their abundance in heavily polluted waters and the fact that it is easy to rear them suggested the use of this species for the toxicity tests considered in our present research. Short exposure tests were carried out to evaluate the LC/sub 50/ of HgCl/sub 2/ for the 4th instar larva of C. riparius Meigen.
