Toxic Metal Chemistry in Marine EnvironmentsPresents an integrated chemical behavior of selected toxic metals: arsenic, cadmium, chromium, copper, mercury, and lead. All important processes that may affect their marine chemistry are discussed. Thermodynamic calculations are performed to propose the most probable route of chemical behavior. Th |
