Lead exposure risks
Informal recycling often targets lead-acid batteries from conventional vehicles, but EV components or hybrid systems may also contain lead. Unregulated smelting releases lead particles into the air, soil, and water, exposing workers and nearby communities. Chronic lead exposure causes irreversible neurological damage in children, including IQ reduction and developmental delays, alongside physical symptoms like gastrointestinal distress in adults. Approximately 16 million people globally face lead poisoning risks from backyard battery recycling.
Lithium-ion battery hazards
While EV lithium-ion batteries themselves contain less lead, illegal recycling methods (e.g., open burning) release toxic fumes from plastic casings, electrolytes, and other components. This process can expose recyclers to carcinogens and respiratory irritants, while damaged batteries pose fire/explosion risks from thermal runaway. Improper disposal in landfills or municipal waste further threatens communities through groundwater contamination and fire hazards.
Global scale of contamination
Illegal operations often relocate to evade authorities, leaving behind thousands of chemically contaminated sites per year. In Bangladesh alone, hundreds of informal recyclers create cascading environmental health crises through perpetual soil and water pollution. The lack of protective equipment for workers exacerbates direct health impacts.
Recommendations
The EPA and environmental organizations emphasize using certified recyclers to prevent toxic exposure. However, enforcement remains weak in regions where informal recycling dominates due to economic pressures.
