  1. Lead poisoning of children in Africa, IV : Exposure to dust lead in primary schools in south-central Durban, South Africa.

    Article - En anglais

    Twenty primary schools in three areas (Merebank, Austerville and Bluff) of south-central Durban, South Africa were studied to determine if dust lead loading (mug/m2) is high enough to constitute a risk to children.

    Atmospheric lead fallout rates in the schools varied from 9 to 264 mug/m2 per day and were higher than the values now being reported in the developed countries.

    Mean outside dust lead loadings were 425 mug/m2 in Merebank, 771 mug/m2 in Austerville and 1174 mug/m2 in Bluff areas, and 25% of the primary schools were found to have mean outside dust lead loading above 1000 mug/m2.

    Mean dust lead loadings inside classrooms were 2-4 times lower than the outside rates, and showed no significant difference among schools in the three areas.

    Dust lead loadings were correlated with lead concentrations in dust but not with distance from the highway or with atmospheric lead deposition rates.

    Exposure to dust lead in classrooms and in the school yard is considered to be an important contributor to blood lead levels in, and hence a potential health hazard to, children in many urban areas of the city.
