RESUMO
In Egypt, one of the main sources of lead exposure is a network of lead pipes used for water supply. Adverse effects of high lead exposure are well known. Many studies have focused on the health effects of low blood lead levels after sharp decline of its exposure levels. Currently, there is a growing concern about threats posed on pregnancy outcomes among women with low to moderate blood lead levels. This study was conducted to evaluate the role of contaminated water as one source of multifactorial lead exposure chain, and to be acquainted if the currently observed lead levels are associated with increased risk of spontaneous abortion in pregnant women in Egypt. The results of this study revealed significant positive correlations between drinking-water lead with both blood lead and abortus lead levels in cases of abortion. Each woman with unexplained spontaneous abortion should be subjected to blood lead estimation. Primary prevention by removing lead from the environment is the only pathway to avoid threats posed on pregnancy outcome since there is no effective remedy to remove lead from the body at levels below 30 microg/dl
