Due to negligent use and disposal of lead containing sources including acid and alkali batteries with lead conductor, vehicle accumulators in last years, environment has been polluted greatly and it becomes the cause of animal poisoning. Heavy metals are dangerous because of their persistence and toxicity. Soil behaves as a sink of heavy metals by aerial deposition of particles emitted by human activities. The aims of this work were to identify the levels of lead in accumulator processing plant and city areas and animals. A total of 60 blood samples were collected in the vicinity of Ulaanbaatar and measured lead concentrations using equipment LeadCare II. Detection limit of LeadCare II for blood lead concentration ranges between 3.3 and 65 μg/dl. Measurements were made in three replicates using the samples, which were diluted by 10 to 100 fold and about 180 units of analysis was carried out. According to our study lead concentration in blood from livestock populations in the vicinity of Khonkhor lake, Nalaikh district is greater up to 52.9 ppm and the concentration in the soil around the factories is 30 fold higher. High lead content were found in soil and livestock animal blood samples of accumulator processing plant, which have correlated positively between them. But lead concentration in the blood sample from animals, which in areas might be free from lead pollution, was higher than acceptable level. In further studies on contamination resources are required.
