Consumption of food crops contaminated with heavy metals is a major food chain route for human exposure. The main threats to human health from heavy metals are associated with exposure to lead, cadmium, mercury and arsenic. These metals have been extensively studied and their effects on human health regularly reviewed by international bodies such as the WHO. Heavy metals have been used by humans for thousands of years.Although several adverse health effects of heavy metals have been known for a long time, exposure to heavy metals continues, and is even increasing in same parts of the world, in particular in less developed countries, though emissions have declined in most developed countries over the last 100 years. Furthermore, this study highlights that both adults and children consuming food crops grown in wastewater irrigated soils ingest a significant amount of the metals studied
