distribution of lead and cadmium levels in the soil of borkhar district of isfahan province

this study aimed to evaluate regional soil borkhar of the metals lead and cadmium has been made. in this field study fires visits to the regions. the limit of this study located in the east refineries, petrochemical and power plant to 20 km was selected. the 41 soil samples from depths of 0 to 10 cm in area and were randomized. soil samples were transported to the laboratory and by air was dry and passed through 2-mil thickness sieve. in the laboratory of physical and chemical characteristics and concentrations of total absorption was measured. the results showed that the concentration of cadmium in soil is higher than the standard limit and the amount of lead in soil in many parts of the range higherthan the standard limit. survey maps show that the lead spatial distribution of the region does not special pattern.
