Breast milk, OCPs, infant health, lactation, endocrine disrupting pesticides


Organochlorine pollutants (OCPs) resist decomposition and continue to contaminate habitats and human health. This study analyzed traces levels of organochlorine pesticides in breast milk samples. A standard questionnaire was procured during the sample collection from all the donors. The study only recruited participants who were willing to donate breast milk samples and have provided their consent. A total of 66 mothers (mean age: 29 years) were voluntarily recruited, all mothers were healthy after delivering the baby. All the participants in this study were residents of Kalaburagi rural areas for at least 8-10 years. Analysis of several OCPs were done using GC (shizmadu GCMS QP2010), the traces of 3 OCP congeners were revealed in the mother’s milk samples. o,p'-DDE, p,p'-DDE and DDT have been determined in the mother’s milk samples. The analysis revealed that most dominant contaminant found was o,p'-DDE which was seen in 32 samples and p,p'-DDE was second most dominant since, it was also determined in 32 samples and least dominant contaminant was DDT which was determined in 8 samples. Our study shows that mother’s diets could have been a major effect on traces of pesticide residue in the mother’s milk. Dietary sustenance guidance like limiting inordinate amount of non-vegetarian foods of obscure sources may play a key role to reduce the traces of OCP excretion in to the breast milk.
