The chironomid communities (pupal exuviae) of groyne fields in a large lowland river in Central Europe (Elbe, Germany) and their potential use for ecotoxicological fiel studies

Abstract

Chironomid pupal exuviae were collected along a stretch of the River Elbe (Germany) to test whether they indicated industrial pollution impacts on the river biota. The communities found were typical for a potamal river region. Among the 134 taxa recorded,
