Lead (Pb) is a naturally occurring metal and generally form lead compounds by combining with two or more elements. Lead reacts with air and water to form lead sulfate, lead carbonates or lead oxide. These compounds act as a protective barrier to prevent corrosion. Lead can also interact with both acid as well as base.
Exposure to lead can affect multiple body systems and is particularly harmful to young children and women of child-bearing age. Lead is distributed to the brain, liver, kidney and bones. It is stored in the teeth and bones, where it can accumulate over time. Human exposure is assessed through the measurement of lead in blood.
Lead present in tap water is rarely the result of its dissolution from natural sources but is mainly due to household plumbing systems containing lead pipes, solders and fittings. Polyvinyl chloride (PVC) pipes also contain lead compounds that can leach into water.
Lead can contaminate drinking water through plumbing systems containing lead pipes, solders and fittings. Young children are particularly vulnerable to the toxic effects of lead and can suffer permanent adverse health impacts, particularly on the development of the central nervous system.
The harmful impacts on health from lead exposure are entirely preventable. Lead is a naturally occurring toxic metal found in the Earth’s crust. Its widespread use has caused extensive environmental contamination, human exposure and significant public health problems globally.
GI absorption of lead is affected by the physicochemical characteristics of the ingested lead particles and by other factors including age, fasting status, diet, and pregnancy (3, 4). Lead competes with calcium for binding proteins involved with GI absorption as they have a similar ionic size.
