Abstract
OBJECTIVES: The use of leaded petrol was prohibited in the Delhi city by the end of 1998. To determine the impact of use of unleaded petrol, this cross-sectional study was conducted to determine blood lead levels in primary school children. METHODS: Blood lead levels were estimated in 300 school children aged 6 to 10 y. The data regarding clinical features and putative risk factors for high blood lead levels was also collected. RESULTS: Of the 300 children, 36 (12 %) had high blood lead levels. Of the 36 children, 32 had blood lead levels between 10 and 19 μg/dl, 4 had 20-44 μg/dl and none had levels >45 μg/dl. Factors such as exposure to peeling paint, recent renovation of housing and near-distance of house to main road were significantly associated with high blood lead levels. CONCLUSIONS: There is significant prevalence of high blood lead levels in school children in Delhi, even after with prohibition of use of leaded petrol.
