Three groups of populations were studied: I. living for about 10 years, II. living for about 3 years near copper smelteries, and III. living in rural area, far from any source of air pollution. Lead content in blood was found to be 182.0 and copper 274.6 microgram/100 ml for group I, Pb - 69.2 and Cu - 253.3 microgram/100 ml for group II, and Pb - 43.8 and Cu - 143.3 microgram/100 ml for group III. Inhibition of glycolytic cycle enzymes and delta-aminolevulinic acid dehydratase was proportional to the duration of exposure to environmental pollution. Ceruloplasmin concentration in serum, as well as serum and red cells aminotransferases activities, were increased in group II and decreased in group I, suggesting certain mechanism of adaptation.

D007854 Lead A soft, grayish metal with poisonous salts; atomic number 82, atomic weight 207.2, symbol Pb.
D007855 Lead Poisoning Poisoning that results from chronic or acute ingestion, injection, inhalation, or skin absorption of LEAD or lead compounds. Poisoning, Lead,Lead Poisonings,Poisonings, Lead
D008099 Liver A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances. Livers
D008297 Male Males
D008708 Methemoglobinemia The presence of methemoglobin in the blood, resulting in cyanosis. A small amount of methemoglobin is present in the blood normally, but injury or toxic agents convert a larger proportion of hemoglobin into methemoglobin, which does not function reversibly as an oxygen carrier. Methemoglobinemia may be due to a defect in the enzyme NADH methemoglobin reductase (an autosomal recessive trait) or to an abnormality in hemoglobin M (an autosomal dominant trait).
