    study examined one of Europe's largest coastal dolphin populations and found that their fat and skin may have accumulated large amounts of pollutants, such as industrial liquids and mercury. The 82 dolphins from the English Channel had the highest levels of mercury known. The paper was published recently in Scientific Reports.
    1970s and 1980s, some developed countries banned the use of toxic organic pollutants, especially chlorine." Even so, such pollutants can still be detected in marine life in the deepest waters. These organic compounds are soluble in oils and fats and are composed of various industrial processes and pesticide by-products. Bottlenose dolphins, also known as bottle-nosed dolphins, are often used to study levels of pollutants in the environment because these organic compounds accumulate under their thick layer of adipose tissue.
    krishna Das and colleagues at the University of Liecht in Belgium selected 82 wild kissing dolphins living in Normano-Breton Bay in the English Channel to study levels of organic pollutants in their fat and mercury levels in their skin. The researchers found higher concentrations of contaminants in the grease, mainly chlorine-containing compounds in industrial liquids (91% male and 92% female). In addition, mercury levels in skin samples are close to those previously found in the Mediterranean and Florida Everglades, where mercury pollution is known to be more severe.
    that Normano-Breton Bay should be classified as a special reserve to protect Europe's largest coastal species of know dolphin. (Source: Lu Yi, China Science Journal)
