Soil Pollution by Lead in Sub-Saharan Africa

Abstract

This chapter discusses the anthropic sources of lead and its subsequent pollution to soils of sub-Saharan Africa (SSA) region. Using examples of east, west, and south African empirical studies, industrial activities characterized by cottage industries involved in paint use, electrical appliance and motor vehicle repair, hairdressing, and scrap metal recycling were associated with Pb introduction in soils leading to their contamination. The use of leaded petrol and manufacture and recycling of Pb- based batteries were additional causes of metal pollution in soils. The contaminant is introduced to soils via Pb-containing dusts, emissions, particulate matter, solid wastes, and effluents. Subsequent transfer to trophic levels is via ingestion, inhalation, and consumption of contaminated soils and food crops. It is essential to manage the sources of Pb to control and manage its accumulation in soil.
