title: Toxic metal pollution in Africa.
abstract: The available information suggests that the concentrations of toxic metals in many ecosystems of Africa are reaching unprecedented levels. Because of the heavy load of contaminated dusts in the air of the overcrowded cities, the ambient concentrations of toxic metals are now among the highest being reported anywhere. Lead pollution from the increasing number of automobiles and cottage industries represents a major health hazard, and it is estimated that 15-30% of the infants in some urban areas may already be suffering from lead poisoning. The cultural and lifestyle determinants of lead exposure and the greater susceptibility of African populations to environmental metal poisoning are highlighted. The suggestion is made that the environmental health criteria for toxic metals in the developed countries may not provide adequate protection for many African communities.
