Endocrine Disrupting Compounds in Lotic Ecosystems: A Review on Its Occurrence, Sources and Effects on Chironomus riparius

Pinheiro C, Pereira R and Vieira M

Water plays a vital and irreplaceable role in the entire ecological balance. The increased human population growth, complemented by an intensification of agriculture, industrial development and urbanization, triggered an increase in pressures on water resources and in its consequent degradation, being that rivers one of the most resources intensively used and disturbed by man. Recent research has revealed the existence of hundreds of organic contaminants named “Emerging Organic Contaminants”. Within this vast group of contaminants, exists a class of xenobiotics capable of mimic hormones designated endocrine disrupting compounds. Since information, about this compounds is rare and spread out, the aim of our work is to examine the occurrence and sources of endocrine disrupting compounds and its effects in Chironomus riparius, an important aquatic insect used in ecotoxicological studies.
