Physical, chemical weathering and volcanic eruptions release heavy metals into soils and
surface waters naturally. Contaminants from anthropogenic sources originated from …

In this chapter organometallic compounds are defined as those which have a carbon to
metal single sigma bond polarized M δ+− C δ−(some useful sources are listed in the …

The contents of Cd, Cu, Cr, Hg, Ni and Zn in muscle, liver and gills were studied in whitefish,
perch, pike, brown trout, burbot and vendace from three lake localities in a watercourse in …

Abstract Concentrations of Hg, Pb, Cd, and Cr in 240 shellfish including oyster, short-necked
clam, razor clam, and mud clam collected from six administrative regions in **amen of China …

Carp (Cyprinus carpio) were tested for cadmium accumulation and elimination during and
after a simulated pollution exposure. Fish were distributed in two 1000-l indoor concrete …

Many studies report negative associations between exposure to large concentrations of
contaminants and life-history traits of animals. As a consequence, they argue to derive linear …

Muscle samples from nine species of freshwater and anadromous fish from the Pechora
River were analyzed for cadmium (Cd), copper (Cu), lead (Pb), and zinc (Zn). Cu and Zn …

This literature review encompasses aquatic environmental toxicities of metals and
metalloids. The emphasis is on the influencing factors on metal toxicity to aquatic organisms …

Studies of the accumulation and toxicity of Cd, Zn, Fe, Pb and Cu under acid conditions to
stream invertebrates are reviewed. The influence of pH on metal speciation decreases in the …
