Levels of alpha 1-antitrypsin in children from areas with different air pollution

Summary A study of alpha 1-antitrypsin (A-1-AT) blood-serum levels was performed in children populations eleven year old at two urban areas in autumn season and at three towns in spring season. In whole 547 blood samples in 312 children were examined. The areas under observations differed especially by the grade of air pollution. The A-1-AT values distribution differed significantly among the children from different areas. The difference were due mostly'to the girl part of the population. A hypothesis was risen that the difference found may have relation to the polluted atmosphere.
