title: Evaluation of environmental waters using the comet assay in Tilapia rendalli.
abstract: Testing for environmental pollutants is an ever-growing concern. Various tests in organisms have been utilized for the detection and identification of toxic substances in the air, water and soil. In the present study, we utilized the comet assay in Tilapia rendalli to conduct an environmental assessment of Lake Igapó II, a lake located in the metropolitan area of Londrina, PR-Brazil. The results demonstrated that samples from Lake Igapó II had a significantly greater number of comets, mainly in classes 2 and 3. The results suggest a genotoxicity of the aquatic environment at Lake Igapó II and that the comet assay in T. rendalli provides adequate sensitivity to be utilized as a tool in the monitoring of water pollution and environmental risk assessment.
