Arsenic effects

Arsenic effectively controls filariasis in cattle new protective uses are under investigation. The control of parasitic nematodes (Parafllaria bovicola) in cattle was successful after 30 weekly treatments in plungement dips containing 1600 mg As203/L. However, the muscle of treated cattle...

Unfortunately, arsenic is chemically similar to both nitrogen and phosphorus, and is readily incorporated into body tissues following ingestion. Arsenic effectively tricks the body into supposing that straightforward incorporation of nitrogen or phosphorus has occurred.

Data on arsenic effects to soil biota and insects are limited. In general, soil microorganisms are capable of tolerating and metabolizing relatively high concentrations of arsenic. This adaptation seems usually to be due to decreased permeability of the microorganism to arsenic. Tolerant soil microbiota can withstand concentrations up to 1600.0 mg/kg however, growth and metabolism were reduced in sensitive species at 375.0 mg As/kg and, at 150.0-160.0 mg As/kg, soils were devoid of earthworms and showed diminished quantities... 

Lorenzen et al. studied the adsorptive removal of arsenic using three activated carbons prepared from different source raw materials and observed that all three activated carbons impregnated with copper were capable of ranoving arsenic effectively from aqueous solutions at a slightly acidic pH of 6. They also observed that the adsorption was not related to the surface area of the carbon but was enhanced by the presence of ash in the activated carbon. Sen and De determined the effect of several parameters such as, the time of equilibration, pH, and adsorbent dose on...
