Field collection of plants

Copper concentrations in field collections of plants and animals are usually elevated in areas treated with copper-containing herbicides, near smelters, and from heavily urbanized and industrialized areas (Stokes 1979 Eisler 1984 Winger et al. 1984 Read and Martin 1993 Swiergosz et al. 1993 Fishelson et al. 1994 Storm et al. 1994). The amount and distribution of copper in animal tissues varies with tissue, organism age, sex, and amount of copper in the diet (Cuill et al. 1970 NAS 1977 USEPA 1980 Fishelson etal. 1994). Additional and more detailed information on copper concentrations in field collections of plants and animals is found in Jenkins (1980) and Eisler (1979, 1981). 

Mercury concentrations in world-wide field collections of plants and animals are documented factors known to modify mercury accumulations and their significance are discussed. 

Total zinc concentrations in nonbiological samples seldom exceed 40.0p,g/L in water, 200.0 mg/kg in soils and sediments, or 0.5 p-g/m in air. Environments heavily contaminated by anthropogenic activities may contain up to 99.0 mg Zn/L in water, 118.0 g/kg in sediments, 5.0 g/kg in soil, and 0.84 p,g/m in the atmosphere. Zinc measurements in field collections of plants and animals show several trends (1) zinc is present in aU tissues of aU organisms measured (2) concentrations are elevated in organisms near anthropogenic point sources of zinc contamination ...
