In News
- A report by Niti Aayog and the Council of Scientific & Industrial Research (CSIR) has found that India bears the world’s highest health and economic burden due to lead poisoning.
Key Highlights of the Report
- Global Findings:
- Around 1 in 3 children – up to approximately 800 million globally – have blood lead levels (BLL) at or above 5 micrograms per decilitre (µg/dL)
- Children around the world are being poisoned by lead on a massive and previously unrecognized scale.
- The impact of lead on adults is so large that over 900,000 premature deaths per year are attributed to lead exposure.
- Many countries lack sufficient formal recycling infrastructure and capacity to handle the quantity of used lead-acid batteries flooding their markets.
- Findings about India:
- It had found India to be home to a major chunk of children (275,561,163 of the 800 million) poisoned by lead globally.
- Most affected states: Bihar, Uttar Pradesh, Madhya Pradesh, Jharkhand, Chhattisgarh and Andhra Pradesh.
- Deaths due to lead poisoning have continued to rise in India even though lead use in petrol — a key source — was phased out by 2000 in the country.
Lead Poisoning
- About:
- Lead is a highly toxic metal and a very strong poison.
- Lead poisoning is a serious and sometimes fatal condition. It occurs when lead builds up in the body.
- Common Sources of Lead Exposure:
- Lead in water from the use of leaded pipes;
- Lead from active industry, such as mining and the unsound recycling of used lead-acid batteries (ULABs);
- Lead-based paint and pigments;
- Leaded gasoline (which has declined considerably in recent decades, but was a major historical source);
- Lead solder in food cans; and
- Lead in spices, cosmetics, ayurvedic medicines, toys and other consumer products.
- Children are also exposed to lead in-utero through exposure of their mothers, with adverse impacts on neurobehavioural development.
- Impact:
- Lead poisoning can cause severe mental and physical impairment. Young children are most vulnerable.
- Exposure to high levels of lead may cause anemia, weakness, and kidney and brain damage.
- Lead is more harmful to children because their brains and nervous systems are still developing.
- Treatment: Lead poisoning can be treated, but any damage caused cannot be reversed.
Way Ahead
- There is a desperate need for policy changes at the national and state levels given the severe health implications.
- These include identifying at-risk populations through BLL monitoring, investigating sources of elevated BLLs and healthcare workforce training to sensitise them to monitor, detect and treat lead poisoning.
- India needs to devise implementable strategies on a state level, through regional bureaucracy, local press and vernacular language to have a tangible impact.
- There is a need to undertake targeted research and intervention studies to identify potential newer sources which policy makers and the scientific community can address head on.
- Childhood lead poisoning should command an urgent international response.
