Abstract Mercury is a persistent, bio-accumulative, and hazardous contaminant. When released into the environment, it accumulates in water sediments, converting to poisonous methylmercury that enters food chain. The present study was carried out habitations from 11 districts of Bihar (India). In study, n = 224 lactating women their infants 172 participated. After obtaining written informed consent, breast milk, urine, blood were collected for mercury estimation. breastmilk content measured 181 subjects, which 74% had higher than WHO permissible limit (< 1.7 μg/L), while 26% milk below limit. showed 19% subjects above [20 μg/L]. urine estimation, 49% [10 μg/L], while, 51% child’s 54% μg/L] 46% indicates 20% complete accumulation body highly toxic them.
