In a study of the effects of increasing climate temperatures on the toxicity of 3 contaminants in different fish species, researchers found that all pesticides and industrial contaminants studied--endosulfan, chlorpyrifos, and phenol--became toxic in the upper 5oC range of species' temperature tolerance.
"Within this narrow range of temperatures, other simultaneous changes--such as reduced shading of the water surface as a result of clearing vegetation or increased toxicant exposure--may combine to significantly increase the vulnerability of fish to global warming," said Dr. Ronald Patra, lead author of the Environmental Toxicology and Chemistry study.
