ABSTRACT
Soil contamination with dangerous toxic chemicals remains one of the most difficult problems in this era. The hazardous chemical may persist in the environment and therefore, the potential for long-term health risk exists. The sources of hazardous chemical wastes are numerous. Industry, agriculture, and institutions such as hospitals and universities are all sources of materials that need to be discarded. People living in proximity to hazardous waste disposal sites or workers at the dump sites are at serious health risk if the sites are poorly managed or improperly designed. Plasma concentrations from 0 min to the time at which maximum concentration was achieved were used for absorption calculations. The half-life of absorption into plasma in the presence of either soil for oral or dermal treatment was not statistically altered compared to their respective controls. Clay soil treatment statistically increased radioactivity in treated skin, while statistically decreasing radioactivity in treated fat compared to benzene alone.
