Summary:OBJECTIVESTo assess the blood lead level (BLL) of school children in 10 cities of India.METHODSThis multi-centric cross-sectional study enrolled participants from randomly selected schools. Data on demographic details, socioeconomic status (SES) and anthropometric indicators was collected. Samples were collected for assessment of lead level in blood. Inductively coupled plasma-optical emission spectrometry technique was used to assess BLL.RESULTSFrom April 2019 through February 2020, 2247 participants were recruited from sixty schools (62.6% government schools) with equal gender distribution. The overall median (interquartile range) BLL was 8.8 (4.8, 16.4) µg/dl. The highest median (interquartile range) BLL was in Manipal 30.6 (23.0, 46.7) and lowest in Dibrugarh 4.8 (3.2, 7.0). Overall, 82.5% of participants had BLL above ≤4 µg/dl. Significant negative correlation was observed between BLL and SES (correlation= -0.24, p
