Boron,ome sedimentary rocks. Boron in this form is largely inert and is released into the environment at an extremely slow rate through natural weathering processes. However, once released from silicate structures, boron forms highly soluble species that are readily absorbed by most plants and animals.

Cadmium,id, preferentially complexing with sulfides, often as greenockite (a hexagonal crystalline form of cadmium sulfide), hawleyite (a cubic crystalline form of cadmium sulfide), sphalerite (zinc sulfide), and otavite (a mineralized form of calcium carbonate). Cadmium is of considerable environmental and

Chromium,ve the generalized formula (Mg,Fe)O(Cr,Al,Fe).O.. Depending on the degree of substitution in the Al, Fe, Cr series, the chromites contain from 13% to 65% Cr.O.. Numerous chromium compounds are manufactured from these minerals, most of which contain chromium in the stable 3 + or 6 + state.

Cobalt,, skutterudite ((Co,Fe)As.), and erythrite (Co.(AsO.).·8H.O). Although the concentration of cobalt in these minerals can be as high as 200 mg/kg, relatively large residues are also found in coal, uranium ores, some crude oils, and other sulfide ores. Vitamin B., essential to humans, contains cobalt.

Mammal

Copper,numerous sulfide minerals. Although the primary copper mineral is chalcopyrite (CuFeS.), metallic copper, chalcocite (CuS.), and bornite are also economically important. Copper is essential in many enzymatic reactions in mammals.

Iron,, siderite (FeCO.), limonite [FeO(OH)], and hematite (Fe.O.). Iron is an essential trace element, required by both animals and plants. In some waters it may limit, either directly or indirectly, the growth of algae; it is also essential to oxygen transport in the blood of all vertebrates and some in
