Abstract
The distribution of cadmium and arsenic in rainwater, surface soil and groundwater in a zone of influence of emissions of a phosphate fertilizer factory has been investigated. The analysis of rainwater along a wind line shows that cadmium in the soluble form precipitates close to emission source, whereas arsenic migrates further and also in the soluble form precipitates at a greater distance. The pH controls the distribution of cadmium and arsenic in rain and groundwater. Concentration of soluble cadmium along the impact line increases with reduction of pH and arsenic, contrary to the increase of pH. Concentrations of cadmium and arsenic in surface soil correlate well among themselves near to emission point. In a zone of confluence of emissions with sea air at a distance from the factory there is sedimentation of arsenic on a geochemical barrier and formation of a separate anomaly in soil.Entities:
