Bioindicator evaluation of toxic trace elements contamination of terrestrial habitats Korgalzhyn Biosphere Reserve

Abstract

The results of a comparative study of content of essential and toxic trace elements in two species of grasshoppers –Chorthippus karelini and Euchorthippus pulvinatus – from different habitats are presented. А relatively low level of elements in the grasshoppers of Korgalzhyn Biosphere Reserve was detected. The results suggest that the toxic trace elements are not a limiting factor for terrestrial insects of Korgalzhyn Biosphere Reserve.
