A Mixed-Methods Study of Pesticide Exposures in Breastmilk and Community & Lactating Women’s Perspectives from Haryana, India

Background Population growth which has resulted in a need for increased crop yields to sustain food security, in addition to the effects of climate change, have led to the widespread use of chemical pesticides. The indiscriminate use of pesticides has in turn led to contamination of the environment, food commodities and bioaccumulation in human tissues, particularly in agrarian regions of India including the northern state of Haryana. Methods We conducted a pilot screening study to investigate the presence of organochlorine, organophosphate, and pyrethroid pesticides in breastmilk samples ( n = 75) from Haryana, India. Pesticide analyses were conducted using gas chromatography mass spectrometry (GC-MS) for OC and OP pesticides and GC-electron capture detector for pyrethroids. The study was complemented by a qualitative evaluation of maternal and community perceptions, knowledge, attitudes and practices associated with pesticide use and risk of exposure ( n = 30 in-depth interviews; n = 9 focus group discussions). Results Analysis of breastmilk showed the presence of p,p’ -dichlorodiphenyltrichloroethane (DDT) and p,p’ -dichlorodiphenyldichloroethylene (DDE) in 4% (range: 更多
