Production of biosurfactant can be substantially increased by the addition of precursors like vegetable oils, petroleum products, and other water-insoluble substances. Pseudomonas Ptm+ strain produces biosurfactant in the presence of hexachlorocyclohexane (HCH), which specifically emulsifies HCH, a recalcitrant organochlorine pesticide. Addition of previously produced crude biosurfactant by the...

Annual survey of Jalmahal, Amer, Nevta and Ramgarh lakes, has been conducted for one calendar year, to determine physicochemical characteristics of water and the levels of zinc (heavy metal) and endosulfan (an organochlorine pesticide). These lakes are situated on the outskirts of Jaipur city. Changes in pollutants correlated well with the physico-chemical characteristics of water bodies. Resul...

Abstract Organochlorine is a synthetic pesticide that has been banned in many countries because of its high persistence the environment and can accumulate animals. The goal our study was to determine level organochlorine residues surface water mussel Corbicula sumatrana Lake Singkarak. Water samples were collected from 10 sampling sites Singkarak, Batu Taba, Sumpur, Guguk Malalo, Ombilin, Tikal...

Background: Pesticides are essential in modern agricultural practices but due to their biocide activity and potential risk to the consumer, the control of pesticide residues in foods is a growing source of concern for the general population. Extensive application of such agents as organochlorine pesticides in farmlands and contemporary agricultural industries has led to undesired environmental ...

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 ...

Rice and fish are common staple foods in many parts of Asia, Africa, and Latin America. The cultivation of fish in paddy fields has proven to be highly productive. Simultaneous rice and fish cultures can be accomplished with l i t t l e extra effort and is economically feasible and practical. Fish enhance rice yield through predation of insect pests, reduce aquatic vascular plant and algal grow...

background: the organochlorine ddt has estrogenic activity but the mechanism underlying the estrogenic activity of this pesticide remains unclear. in the present investigation here, we studied the transcriptional effects of a synthetic organochlorine pesticide o,p’-ddt [1.1.1.-trichloro-2-(o-chlorophenyl)-2-p-chloriphenyl ethane] and its metabolite p,p'-dde (2-2-bis(4/chlorophenyl)-1-1-dic...
