Relative Importance of Non-Point Sources of Mercury to an Industrialized Coastal System, Sepetiba Bay, SE Brazil

摘要: Estimation of Hg emissions to air, soil and water is the first step in regional management control areas where contamination potentially significant no clear point source this metal exists, such as diversified industrial parks. Sepetiba Bay basin, SE Brazil, an example a situation. Over 400 industries, from oil-fired power plants steel non-ferrous manufacturing plastics chemicals, have been installed region since late 196os. Important sources metals Cd, Zn Pb identified controlled during past decade; Hg, however, has area.
