Toxic Elements in Soils
MAMMALS and birds sometimes seek shelter or nesting sites in the ground. Many of them scarcely affect the soil as a medium for plant growth. A notable exception is the soil-dwelling rodents. Although their acreweight is usually only about a few pounds even in the uncultivated land, their soil transporting activities sometimes are considerable. In building their tunnels and nests, they transport...
متن کاملEvaluation of Potentially Toxic Elements Pollution Indices in Rangeland Northwest of Chadegan city (Isfahan Province)
Abstract Today, the pollution of Rangeland soils by various destructive pollutants has become one of the human-environmental problems. Lacking proper management of organic matter discharge can also increase the concentration of salts, heavy metals, and pathogenic microorganisms. In this study, to investigate and measure the concentration of toxic elements, 128 soil samples of Chadegan region w...
متن کاملEvaluation of stream sediment contamination by potentially toxic elements around mining and farming areas (SE Nigeria)
In this work, the concentrations of the potentially toxic elements in stream sediments in SE Nigeria were assessed for pollution monitoring in mining, quarrying, and farming areas. The levels of iron, molybdenum, vanadium, copper, lead, zinc, nickel, cobalt, manganese, chromium, barium, and beryllium were determined. The concentrations of the elements were in the order of Fe > Ba > Mn > Cr > Zn...
متن کاملbioavailability and speciation of potentially toxic elements in agricultural soils neighboring an industrial complex in northwest isfahan, iran
the mobility and bioavailability of trace elements in the agricultural soils are extremely important in assessing the risk of toxicity to the growing plants. a five step sequential extraction procedure (sep) has been employed to study the speciation of as, sb, cr, cu, cd, pb, zn, ni, fe and mn in 18 soil samples neighboring an industrial complex in isfahan, central iran. enrichment factor (ef) ...
متن کاملStudy of contamination, sources and health risk of potentially toxic elements in dusts of Tehran’s elementary schools
Concerns about dust contamination with potentially toxic elements are especially important in environments such as schools (particularly elementary schools) because children are more vulnerable to contaminants than adults. Therefore, due to the diversity of air pollution sources in Tehran, the present study was conducted to determine the severity of pollution, origin and health risk assessment ...
