“…Numerous studies on both human and laboratory animals provide strong evidence of the toxic potential of exposure to OCPs. The health effects associated with OCPs include reproductive failures, birth defect, endocrine disruption immune system dysfunction and cancer [5][6][7][8] . Studies also revealed that OCPs have strong potential to cross placental barriers even in minute concentration and cause serious neonatal damage [9] .…”

Abstract:The organochlorine pesticide (OCPs) residues were measured in three species of fish Tilapia zilli (Red belly Tilapia), Ethmalosa fimbriata (Bonga Shad) and Chrysichthys nigrodigitatus (Catfish). These fish species are a significant part of the diet of residents of Lagos Nigeria. The organochlorine pesticides analyzed include DDT(pp'1,1,1-trichloro-2,2-bis-(4-chlorophenyl) ethane), DDD, DDE (pp 1,1-dichloro-2, 2-bis-(4-chlorophenyl) ethylene, HCH (gamma 1,2,3,4,5,6-hexachlorocylohexane, HCB (hexachlorobenzene), Dieldrin (1,2,3,4,10,4,4a,5,6,7,8,4,5,8 dimethanonaphthalene) and transnonachlor. The analysis was done using Gas Chromatograph with Electron Capture Detector. The mean concentration of OCPs ranged from 0.01-8.92 ppm. The concentration of the OCPs (except for HCHs) in fish samples in this study were below the extraneous residue limit of 5 ppm, set by the codex alimentarious commission of FAO-WHO-1997. However, the concentrations were higher than those detected during previous studies of fish samples from Lake Victoria, Uganda in Africa. Also the levels were quite high when compared with the allowable Federal Environmental Protection Agency (FEPA), now Federal Ministry of Environment limit and can be harmful if the trend is not checked. The study also showed that concentration of OCPs were higher in adult, than in Juvenile of most of the fish and there was no correlation observed between fat content and total concentration of OCPs.

Measurement is the foundation of exposure science. Associations between illness and environmental agents have been observed for millennia, but the ability to quantify exposure and dose has been possible only in the last century. Improved means of measurement and refined concepts of who, what, when, where, and why to measure have been the seminal contributions of exposure science to the study of disease causation and prevention. This paper examines critical advancements in exposure assessment associated with workplace health and safety, and the groundbreaking work of the US Public Health Service. Many of the key concepts of modern exposure science have their origin in these early studies. Occupational hygiene scientists have conducted receptor-based exposure analyses for more than 80 years, evaluating indoor air, defining microenvironments, and developing personal sampling techniques. Biological monitoring of community populations including children, dermal exposure monitoring, duplicate diet studies, and multipathway, aggregate exposure assessments can be traced to early public health studies. As we look to the future, we see that new technologies and techniques are expanding the scope of exposure science dramatically. We need to ensure that the highest of scientific standards are maintained, make a greater effort to include occupational hygiene scientists, microbiologists, and behavioral scientists in the field, and promote new sources of training and research support. Exposure science has a critical role to play in the prevention strategy that is central to public health.
