Under pressure from existing and emerging contaminants, lotic ecosystems are becoming increasingly susceptible to ecological deterioration. Therefore, investigations of the impacts persistent organic pollutants (POPs) heavy metals on riverine fish health, water quality, biotic integrity critical. We examined effects 52 POPs health land use, based monitoring assemblages river quality 2007 2014. ...

organochlorine compounds such as, polychlorinated biphenyls and organochlorine pesticides are among the best known classes of contaminants because of their potential for magnification and harmful biological effects. in this study, the amounts of organochlorine pesticides including d.d.t and its metabolites, α, β and γ-hchs isomers, σcyclodiene (endosulfan, heptachlor, heotachlor epoxide, aldrin...

conclusions in conclusion, toxicological studies showed that, although contamination level in caspian sea fishes was relatively low, the present status might pose a risk about food chain contamination. results the review showed that nine studies were recorded in databases about pesticide residues in caspian sea fish tissues. these studies reported that there is limited evidence of organochlorin...

Persistent organochlorine residues in the environment are a threat to ecological health of aquatic organisms and pose risk both animals human consumers. Organochlorine pesticides were determined water sediments collected during wet dry season from selected riverine earthen fish pond sites high altitude catchment areas within Kuja River (Kenya) between August 2016–May, 2017. Analysis DDT metabol...

Ecological risk assessment of pesticide residues is not only germane but critical in view their inherent health challenges and for informed decision-making process. This study was conducted to assess the levels contamination organochlorine water from Nwaniba River Uruan Local Government Area Akwa Ibom State. The analysis carried out using Gas Chromatography with electron capture detector (GC-EC...

background: the presence of organochlorine pesticides in the environment is a serious threat to human health and requires continuous monitoring. therefore, in the present systematic review, the residual amount of different organochlorine pesticides in human samples has been investigated.   methods: all accessible databases in english and farsi were searched by using organochlorine and related p...

Remote alpine lakes do not receive any direct aquatic inputs from anthropogenic activities. Therefore, these ecosystems may receive persistent organic compounds (POPs) by direct atmospheric deposition, only. Consequently, fish dwelling in these ecosystems represent an excellent indicator for the long-term atmospheric input of bioaccumulating and persistent contaminants. In the present study, fi...

BACKGROUND There is conflicting epidemiological evidence concerning an increase in risk of non-Hodgkin's lymphoma (NHL) associated with elevated blood levels of persistent organochlorine (OC) pesticides and polychlorobiphenyls (PCBs). METHODS We measured the concentration of 17 OC pesticides, including hexachlorobenzene (HCB), four lindane isomers (alpha-, beta-, gamma- and delta-hexachlorocy...

Blubber was collected from live-captured, adult male white whales (Delphinapterus leucas) from Svalbard, Norway, and analysed for levels and patterns of organochlorine (OC) contaminants. The OC compounds analysed were HCB, dieldrin, sigmaHCH (alpha-HCH, beta-HCH and gamma-HCH), sigmaChl (heptachlor epoxide, oxychlordane, cis-chlordane, trans-nonachlor, and cis-nonachlor), sigmaDDT (pp'-DDT, pp'...
