    Journal: Indian J Pediatr; 1999; 66(1):27-35. PubMed ID: 10798033.
    Abstract:
    In order to examine the prevalence of lead exposure and iron deficiency in Jammu, blood lead (B-Pb) and erythrocyte protoporphyrin (EP-ZnPP) levels were measured in a group of 125 children and compared with B-Pb and EP levels of 46 New Delhi children. The mean B-Pb level of Jammu children was 15 micrograms/dl and ZnPP level 46 micrograms/dl. The frequency distribution of B-Pb in Jammu children according to the 1997 CDC stratification showed that only 33% were below the 10 micrograms/dl "normal" threshold levels and 50.5% were between 10-19 micrograms/dl, an increasing level of concern. The remaining 16.5% were in the medical intervention lead poisoned level between 20-87 micrograms/dl with corresponding EP levels between 29-160 micrograms/dl. The mean B-Pb and ZnPP levels for New Delhi children were 14 micrograms/dl and 55 micrograms/dl respectively. This study on Jammu children shows a modest increase in mean B-Pb and EP levels from those in 1985; the percentage of children with higher levels of B-Pb > 10 micrograms/dl have significantly increased. Moreover, the continued underlying high prevalence of iron deficiency among these children predisposes them to increased lead absorption from various sources thus aggravating further, the detrimental effects of lead. Therefore, a more extensive screening of all children below 10 years of age and an ongoing B-Pb and EP monitoring and iron supplementation programme for Jammu and New Delhi is essential. An environmental assessment of the sources leading to serious lead intoxication problem in Jammu, a rapidly growing and overpopulated city of the state of Jammu and Kashmir is strongly recommended.
