Biodegradation of chloroethene compounds has been a matter of intense scientific investigation since these compounds were first identified in the late 1970s as common contaminants in groundwater systems. Over this period, perspectives on chloroethene biodegradation and on the role of organochlorine compounds in the environment have changed substantially. Before 1980, chloroethene contaminants w...

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...

introduction several hundred pesticides of different chemical compositions are currently used for agricultural and vector control purposes all over the world. because of their extensive use, they are detected in various environmental matrices, such as soil, water, and air. due to their lipophilic nature, hydrophobicity, and low chemical and biological degradation rates, organochlorine pesticide...

the levels of 19 organochlorine pesticides (ocps) in surface water and under water sedimentsfrom tanks located nearby the prime agricultural areas of kanyakumari district, tamil nadu, india wereinvestigated to evaluate their pollution risks. a total of 36 surface water samples at 9 sampling sites and27 sediment samples at 9 sampling stations were collected from tanks, which were the water sourc...

organochlorine contaminants are highly stable and dangerous compounds, which are widespread in the environment. among these compounds, polychlorinated biphenyls (pcbs) are carcinogenic for humans and can also affect intellectual functions and the nervous, immune and reproductive systems. aquatic organism especially fishes are known to be main routes for e entrance of these compounds to the huma...
