Persistent organic pollutants (POPs) are industrial chemicals with long half-lives. Early life exposure to POPs has been associated adverse effects. Fetal is typically estimated based on concentrations in maternal serum or placenta and little known the actual fetal exposure. We measured of nine organochlorine pesticides (OCPs), ten polychlorinated biphenyl (PCB) congeners, polybrominated diphen...

Initiated in 1992, air monitoring of organic pollutants in the Canadian Arctic provided spatial and temporal trends in support of Canada's participation in the Stockholm Convention of Persistent Organic Pollutants. The specific analytical laboratory charged with this task was changed in 2002 while field sampling protocols remained unchanged. Three rounds of intensive comparison studies were con...

The use of aldrin, dieldrin, endrin, heptachlor and hexachlorobenzene (HCB) has been banned in Jordan officially in 1981, and of dichlorodiphenyltrichloroethane (DDT) in 1995. However, residues of such compounds can still be found in the environment and in foodstuffs. Dairy products are an important exposure route for organochlorine pesticides (OCPs) to humans. For this reason, the presence of ...

Concentrations of polybrominated diphenyl ethers (PBDEs), and organochlorine pesticides (OCPs; DDTs, HCHs, CHLs, and HCB) were measured in human breast milk samples collected across Massachusetts, USA, in 2004. Seventeen PBDE congeners were found in the samples, ranging in concentration from 0.06 to 1910 ng g À1 lipid wt. 0 ,6-pentaBDE) were the major congeners detected in breast milk samples. ...

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. ...

To assess organochlorine compound (OC) contamination, its possible sources, and adverse health impacts on giant pandas, we collected soil, bamboo, panda fecal samples from the habitat research center of Qinling (Ailuropoda melanoleuca qinlingensis)—the rarest recognized subspecies. The polychlorinated biphenyls (PCBs) pesticides (OCPs) concentrations were comparatively low which suggests that m...

Organochlorine pesticides were widely used in Egypt; large quantities had been released into the environment, where they became persistent substances both in the environment and in the food chain. The non organized use of pesticides in Egypt has caused immense damage to the environment and human health. Recent studies have reported an association between exposure to organo-chlorines pesticides ...

The methods of sample purification for determinations of organochlorine pesticides (OCPs) in sediment and fish muscle were investigated in this study. A two-step procedure with preliminary cleanup and florisil column fraction was adopted. The working conditions of florisil column were firstly optimized. As to preliminary cleanup, liquid-liquid extraction by mixture of dimethyl formamide (DMF) a...

The Antarctic continent is among the most pristine regions; yet various organic contaminants have been measured there routinely. Air and snow samples were collected during the austral spring (October-November, 2010) along the western Antarctic Peninsula and analyzed for organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) to assess the re...
