Agrochemicals in the maternal blood, milk, and cord blood: a source of toxicants for prenates and neonates.

Abstract The circulating blood, breast milk, and cord blood, collected 24–48 hr after child birth of nursing Indian mothers were examined for the presence of organochlorine insecticides (OCI). Significant levels of BHC and DDT were found in all milk, blood samples, and neonatal blood (cord blood) of mothers. No effect of social status, age, dietetic habits, or area of residence on the susceptibility of subjects examined to accumulate OCI was noticed. Significant correlations of total DDT and BHC levels were observed among maternal blood, neonatal blood, and breast milk. The presence of OCI in the cord blood indicates their passage across the placenta to prenates, whereas contamination of breast milk which is consumed by neonates could shed some light on a far greater daily intake of toxic agrochemicals by neonates.
