The children attended four schools situated in the villages: Uhnin, Debowa Kłoda, Urszulin and Debina. There were stated the lower contents of lead and zinc (1.84 and 101.1 micrograms/g) and higher concentrations cadmium and copper (0.37 and 16.44 micrograms/g respectively) in the children's hair from Debina, comparing to the other villages. The statistical analysis of the results revealed essential difference in the mean lead contents according to sex (more, in the boy's hair).
