Behavior of Mercury in Natural Systems and Its Global Cyclepast decade. Also, because of the known volatility of mercury, there has been a great deal of concern about its sources, sinks, and transfers in the environment. In this paper, we discuss the thermodynamic and kinetic (chemical and biological) aspects of mercury and its compounds in an attempt to ex

Because of this cumulative property of cadmium it is possible to produce in experimental animals, either by feeding or parenteral administration, similar total body burdens and liver a

The Significance of Multielement Analyses in Metal Pollution Studies metals, exemplified by the effects of organic mercurials on fish and fish predators and on humans (Jernelov, 1972; Ui, 1971). Since then the effects of lead, cadmium, copper, and chromium have been or are currently being reexamined. When the hazard is manifest as an acute lethal episode, the end re

Entry, Distribution, and Fate of Heavy Metals and Organohalogens in the Physical Environmenthus one of the major problems in understanding trace metals and their transport in the atmosphere is distinguishing between the natural and anthropogenic components. While this is often relatively easy to do in or near urban areas, it becomes increasingly difficult on a regional and global scale.

Uptake, Fate, and Action of Heavy Metals and Organohalogen Compounds in Living Organismsetals, is twofold: (1) a perturbation might be caused to the total ecosystem that could escape man’s control because of the sudden or gradual removal of populations essential to the stability of the system or parts of it; (2) large amounts of accumulated toxic material might be introduced into the h

Evaluation of these effects eventually requires an assessment of the toxicity of residues to species existing in the total environment including plants, animals, air, water, and sediments.
