Regulation of metals

Regulation of metals in soil, sediment, and water systems... 

This chapter is organized as follows We first attempt to discuss, in terms of simplified models, how particles carrying functional groups behave in solutions whose variables are known or controlled. This is followed by observations and interpretations on the concentration of trace elements in rivers and how these trace elements are distributed between particulate and dissolved phase. Then, we will consider the regulation of metal ions and of other reactive elements in lakes above all, it will be shown that the interaction of these trace elements with biotic and non-biotic particles and the subsequent settling of these particles will be of utmost importance for their removal from the water/column. Finally considerations will be given to inquire to what extent similar interpretations can be given to oceans.

Chemical Volume Reduction Incineration has been the method commonly used to reduce the volume of wastes chemically. One of the most attractive features of the incineration process is that it can be used to reduce the original volume of combustible sohd wastes by 80 to 90 percent. The technology of incineration has advanced since 1960 with many mass burn facihties now have two or more combustors with capacities of 1000 tons per day of refuse per unit. However, regulations of metal and dioxin emissions have resulted in higher costs and operating complexity.

The deposition of other sparingly soluble metal compounds is usually associated with disturbances in homeostasis, i.e. the delicate regulation of metal ion concentrations in body fluids, due to various forms of disease. If these disorders result in metal overload of body fluids, solids may deposit in various tissues and damage them. In humans, metal overload diseases concern primarily iron and copper ions, which are moreover intimately...
