[Lead pollution of work sites in auto body repair shops].

Because of the lead in street dirt and in varnishes of cars it is possible that welders in carriagebody repairs get an unnormal lead exposure. We studied the results of measurements of welddust and their lead concentrations in connection with biological monitoring for lead exposure of the welders. Seperately high lead concentrations in the air of the working zone were obtained indicated through blood lead levels higher than normal value. However the parameter for lead effect erythrocyte protoporphyrin kept normal.
