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 کاملDIFFUSE REFLECTANCE MEASUREMENTS FROM DIFFERENT SURFACES
Relative diffuse reflection measurements from the original and ground surfaces using a He-Ne laser are reported. The intensity measurements for the metallic, transparent dielectric, matte plastic surfaces and colored papers are presented. Our results indicate that among metallic surfaces tested, aluminum has the highest diffuse reflectance; while the original stainless steel surface shows the l...

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 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...
