Health impact of lead toxicity in Bangladesh
Lead (Pb) is an elemental heavy metal found naturally in the environment as well as in manufactured products. Lead can be released directly into the air, as suspended particles. Lead poses a severe threat to human health and the environment. Many populations have been exposed to environmental lead from paint, petrol, and mining and smelting operations in Bangladesh.

Lead Contamination in Everyday Food
Lead (Pb) is a heavy metal element found naturally in the environment as well as in manufactured products. The Earth’s crust contains lead that can be released directly into the air as suspended particles. Lead is a chemically resistant and relatively soft metal. Anthropogenic activities such as the burning of fossil fuels, through vehicle exhaust, suspended atmospheric particles, untreated municipal sewage in urban areas, fertilizer and pesticide use in agriculture, a limited planned capacity of municipal solid waste, and mining operations, especially coal in Bangladesh also releases lead in the atmosphere. The atmospheric transmission and deposition on food, soil and other surfaces are the major sources of lead contamination in our daily food.
