Captive Dolphins Test Lower for Mercury than Wild Ones!






"The mercury found in marine animals often originates from coal-fired power plants. These plants emit mercury into the atmosphere and it later deposits into surface waters and oceans, where bacteria turn it into methylmercury. Methylmercury ingested by smaller marine organisms makes its way up through the sea's food chain, resulting in bioaccumulation throughout the ecosystem, most noticeably in aquatic apex predators. This study aims to shed light on the impact of mercury on the oceans, which humans rely on for food."

Insecticides Exceed Regulatory Limits Globally!




 "According to a new study, regulatory limits for insecticides are exceeded in over half of contaminated water samples collected from around the world. The study was based on a review of more than 800 studies conducted in 73 countries over the past five decades and is the first to evaluate the exposure of surface waters to particularly toxic agricultural insecticides on a global scale."
