Abstract
The analysis of long-term state of chironomides at soft sediments in Utulik-Murino site, influenced of Baikalsk PPC, is fulfilled. 79 chironomid species is found, 9 of them are endemics of Baikal. The diversity of chironomides in the waste waters discharge is higher than in control sites but the number of chironomid species in sites
directly influenced by waste waters of BPPC is twice and more lower, than in provisionally pure ones. Unusual for the open Baikal species are found in the zone of BPPC influence. The changes of composition and structure of chironomid community are discussed. The changes of chironomid community are connected with natural reasons as well as with BPPC influence.
