New Delhi, 03 Jun ,2008 : A new study by Toxics Link, has revealed alarmingly high level of lead in household dust in Delhi. This has serious implications especially for children who ingest the dust while playing, and is surprising since lead in petrol has been removed since 2000. It indicates that there are other sources of lead, such as paints, which could be contributing to these levels. It is not unlikely that the situation is similar in other cities in the country.
