Persistent halogenated xenobiotics such as chlorinated cyclodienes are known to be subject to atmospheric longrange transports into Arctic and Antarctic regions [Arctic Monitoring and Assessment Programme (AMAP) 2004]. As a consequence, chlordane, a complex mixture of various chemically similar components, has been detected in biota of these remote areas. Among the major constituents of this mi...

A simple and efficient method for simultaneous gas chromatographic (GC) determination of 18 organochlorine pesticides [tecnazene, hexachlorobenzene, alpha-benzenehexachloride (BHC), pentachloronitrobenzene (PCNB), gamma-BHC, heptachlor, aldrin, methyl pentachlorophenyl sulfide, beta-BHC, delta-BHC, heptachlor epoxide, alpha-endosulfan, trans-chlorodane, cis-chlorodane, p,p'-dichlorodiphenyl dic...

Tomato (Lycopersicum esculentum) is prominent among vegetables produced in Ghana. About ninety percent (90%) of the population of the study area are engaged primarily in tomato production. Due to the problem posed by pests and diseases and the vulnerability of vegetables to most of these pests and diseases, a variety of pesticides including organophosphates, Organochlorines, carbamates, and syn...

The residual cyclodiene insecticides aldrin (A), dieldrin (D), heptachlor (H) and isodrin (I) can be converted by sunlight and ultraviolet light to their corresponding respective photoisomers photoaldrin (PA), photodieldrin (PD), photoheptachlor (PH) and photoisodrin (PI) (1,2,3,4). PA, PD and PH appear to be more toxic than their parent compounds to adults of the housefly, Musca domestica L. a...
