Inorganic chemical characteristics

The chemicals in water may be inorganic elements or molecular species. Inorganic chemicals characteristic of groundwaters and surface waters are different. The importance given to the type of chemical contaminant present is dependent primarily on the potential health risk associated with it. Arsenic, barium, cadmium, and chromium are potentially carcinogenic elements. Mercury, lead, and selenium also have been proven to be toxic. These elements and their molecular species are high priority contaminants because their presence even in very small amounts could render the water toxic and nonpotable. 

This section relates the chemical characteristics of inorganic and organic hazardous wastes to the important fate-influencing geochemical processes occurring in the deep-well environment. 

Mainly inorganic, especially mixtures of metals with similar chemical characteristics, e.g. lanthanides separation of amino acids. 

The ABS will not degrade inorganic or synthetic compounds. The technology s efficiency varies with temperature, moisture, site geological, and chemical characteristics. A biotreatability study may be required to determine a treatment application. 

The GT-1000 microbes cannot degrade inorganic compounds and the biodegradation rates are dependent on temperature, moisture, and slurry and chemical characteristics. 

To accommodate the rapid diffusion that is often needed to supply food, water, and inorganic ions to cells, membranes contain a variety of small pores and channels. The pores may be nonspecific or they may be selective for anions or cations or for some other chemical characteristics. They may be permanently open or sometimes closed and referred to as gated. 

The simple definition of biological availability as the fraction of the total trace metal available for uptake by the biota implicitly assumes that all relevant organisms will have similar uptake characteristics. In addition the use of biological availability as a chemical parameter involves the assumption that it can be identified with particular chemical species or groups of species. Perhaps surprisingly many of the studies carried out to date have lent support to these assumptions, though the detailed mechanisms of the uptake processes remain unclear. Some of the inorganic chemical species identified as... 

The short-term, in situ bioavailability of organic matter is a complex function of intrinsic factors, such as the chemical characteristics of the DOM itself, which include of molecular weight distribution, the nutrient contents, and the relative contribution of broad classes of compounds and are determined by the source and the diagenetic state of the matter (Amon et al., 2001). The utilization of DOM and its apparent lability are also affected by extrinsic factors regulating the metabolism of bacteria and, therefore, the utilization of the organic matter by the bacterial community. These factors include temperature, the availability of inorganic and trace nutrients, trophic interactions within microbial food webs, and even the...
