Urban Indian private schools at risk of proximity to toxic lead sites: report
CGD analysis links 2.6 million schools in 17 countries to 11,301 documented toxic sites, with New Delhi reporting over 90% proximity for private schools to hazardous contamination.

- Lead is harmful to children even at low exposure levels, affecting kidneys and the heart and raising blood pressure.
- Lead acts as a neurotoxin in children, harming learning and cognition-related brain processes.
- Informal lead-acid battery recycling can release heavy metals into soil and air when batteries are opened, casings are burned, and lead is recast.
- Exposure is not only about staying near a toxic site; people kilometres away can still show higher exposure markers.
What happened: CGD analysis finds many schools near documented toxic sites
A Center for Global Development (CGD) analysis on pollution proximity in low- and middle-income countries (LMICs) finds that schools are often located near documented toxic sites. The CGD evidence highlights a stronger pattern in urban areas than in rural areas.
CGD’s reported quantitative findings include:
UPSC may frame the topic as how land-use choices, weak enforcement, and informal hazardous-material pathways create unequal exposure risk for children—especially in cities where schools and toxic sites cluster.
