What is the prevalence of lead poisoning in India?
Lead poisoning is widespread in India, with more than 294 million children estimated to have blood lead levels (BLLs) above five μg/dL, the actionable threshold set by the WHO, according to the Global Burden of Disease (GBD) study 2021.
“Over 23 states report average BLLs exceeding this level, making India one of the most affected countries globally. Children under five are particularly vulnerable due to their heightened susceptibility to lead’s neurotoxic effects. Pregnant women are also at risk, as lead stored in bones can re-enter the bloodstream, affecting both maternal and foetal health,” Chandan explained.
Globally, estimates suggest that 1.5 to 5.5 million lives are lost each year due to lead exposure, largely from its damaging effects on cardiovascular health. He also revealed that lead poisoning affects many countries, but India’s incidence is among the highest, primarily due to a combination of industrial pollution, informal recycling practices, and the use of lead-based products.
