#India – Lead in drinking water stunts kids’ growth


DC |
Bengaluru: With the city facing a shortage of clean drinking water, the National Referral Centre for Lead Projects in India (NRCLPI), based at St John’s Hospital, Bengaluru, is engaged in a project to evaluate polluted rivers around the city that are major source of lead poisoning.
The NRCLPI is working on the project in association with undergraduate students across six cities — Bengaluru, Hyderabad, Pune, Lucknow, Dehradun and Karad. The three-month project is expected to be completed by June 2013, prior to the onset of the monsoon.
The data collected after analysis will be submitted to government bodies and policy makers, says Dr Thuppil Venkatesh, principal adviser, Quality Council of India (QCI) and NRCLPI.
Lead affects the growth and development of cognitive function among children and reduces their IQ. Among adults it affects the kidneys, bones, muscles and also blood pressure.
With the help of NRCLPI experts, the student volunteers will collect samples for analysis using the latest technology. The samples will be evaluated for lead content in soil, in agricultural products and in drinking water within 500 metres of the flowing and highly contaminated rivers and water bodies in these six cities of study. The data will be used to correlate with the health status and Blood Lead Levels (BLL) of the people living in and around the places taken up for the study.
“Rivers in these six cities are now highly polluted, especially with contaminating lead due to increasing industrial activities, mainly from lead-based industries,” says Dr Venkatesh.
“Cattle drink this water. Water from these highly contaminated rivers is used for agricultural purposes and it also recharges the nearby ground water.”
NRCLPI has conducted similar studies on lead contamination, one of which resulted in unleaded gasoline being used across the country. NRCLPI also played a major role in bringing down the content of lead in paints.
If it can rid river water of lead contamination it will go a long way in preventing many illnesses. If this project is successful, it can be extrapolated to other rivers in other cities where a similar situation is seen, Dr Venkatesh said.
