Lead concentration in venous blood (Pb-B) was investigated in 1122 inhabitants (including 555 children under 10 years of age) of five Polish towns with no large industrial lead emitters (group I) and in 1246 persons (707 children under 10 years of age) living in the vicinity of zinc and copper mills (group II).
The samples were analysed using electrothermal atomic absorption spectrometry (ETAAS) and the performing laboratory participated in the external quality control scheme during the study period (1992-1994).
In group I the mean geometric Pb-B concentrations ranged from 23.8 to 48.3g/l in females, from 42.5 to 76.8 g/l in males and from 29.9 to 62.5 g/l in children.
In group II, the mean geometric Pb-B concentrations were significantly higher and ranged from 49.4 to 105 g/l in females, from 98.5 to 149 g/l in males and from 73.7 to 114 g/l in children, the values decreasing as the distance from the source of emission increased.
Cigarette smoking was found to bring about a significant increase in Pb-B levels for both males and females.
A significant correlation was noted between Pb-B concentrations in mothers and children.
The ratio between child and maternal Pb-B concentrations amounted to approximately 1.0 for group I and to about 0.5 for group II.
These findings indicate the necessity of undertaking preventive activities over the lead-contaminated areas.
However, the lead hazard in Poland seems to be associated with point sources of emission and...
