Use of Chironomid Larvae as Bio-Monitoring Agent to Assess Water Pollution

Abstract

In environmental monitoring of water bodies, the morphological deformities of chironomid larvae offer a useful way of estimating sediment toxicity. Laboratory and field studies have indicated a link between morphological deformities of chironomids and the concentrations of toxic substances present in sediments. Midge larvae are able to metabolize organic contaminants, but the breakdown products may also be responsible for morphological abnormalities. The frequency and severity of mouth part deformities of bloodworm and the relationship of deformities to river hydrology have been investigated.
