Monitoring of Organochlorine Pesticide Residues in Human Breast Milk in the Northern Governorates of Jordan in 2019/2020 Compared with the Results of 2015 Study

One hundred and twenty samples of breast milk were collected from five northern governorates and districts in Jordan in 2019 and 2020 to monitor results for organochlorine pesticides as organic contaminants. The results showed that 36 samples (30%) of total 120 analyzed samples were contaminated as follows: 16 samples (13.3%) were contaminated with dieldrin, 4 samples (3.3%) with p,p'-DDE, 4 samples (3.3%) with p,p'-DDD, 8 samples (6.7%) with p,p'-DDT and 4 samples (3.3%) with o,p'-DDE. Comparing results of the current study with those of 2015 study, no residues for the HCHs in 2019/2020 study have been detected, an increase in the DDTs occurred and an increase in the cyclodiens in the 2019/2020 compared to the 2015 study.
