The sterile insect technique (SIT) is a biological control tactic that is used as a component of area-wide integrated pest management (AW-IPM) programs. The SIT can only be applied against disease-transmitting mosquitoes when only sterile male mosquitoes are released, and the blood-sucking and potentially disease-transmitting females are eliminated from the production line. For Anopheles arabie...

This study investigated the presence and levels of organochlorine pesticides (OCPs) (hexachlorobenzene (HCB), α‐, β‐, δ‐, and γ‐hexachlorohexane (HCH), dieldrin, dichloro-diphenyltrichloroethane (p,p’-DDT), dichloro-diphenyl-dichloroethylene (p,p’-DDE), dichloro-diphenyldichloroethane (p,p’-DDD) and trans-nonachlor) in Solanum lycopersicum and Capsicum annuum samples commercially sold in Nigeri...

The concentrations of total mercury, polychlorinated biphenyls (PCBs), and organochlorine pesticides (SigmaDDT, dieldrin, hexachlorobenzene [HCB], and SigmaHCH) were determined in 61 whale meat products (bacon, blubber, red meat, liver, intestine, and tongue) purchased from retail outlets across Japan. Mean (range) concentrations of contaminants in all samples were: total mercury 4.17 (0.01-204...

Use of chlorinated hydrocarbon pesticides for more than 30 years and polychlorinated biphenyls (PCB) for more than 40 years has resulted in the accumulation of these compounds in various ecosystems. Their accumulation in different ecosystems both near and well removed from their source of application is enhanced principally by their persistence and subsequent magnification between trophic level...

To improve biodegradation strategies for chlorinated pollutants, the roles of soil organic matter and microbial function need to be clarified. It was hypothesised that degradation specific fractions in soils enhance community metabolic capability degrade pollutants. This field study used historic records dieldrin concentrations since 1988 established relationships between dissipation carbon tog...

Organochlorine insecticides and their degradation products contribute to toxicity in Chesapeake Bay, USA, sediments and affect the reproductive health of avian species in the region; however, little is known of atmospheric sources or temporal trends in concentrations of these chemicals. Weekly air (n = 265) and daily rain samples (n = 494) were collected over 2000 to 2003 from three locations i...
