BACKGROUND & OBJECTIVES Jiroft district has subtropical climate and prone to seasonal malaria transmission with annual parasite index (API) 4.2 per 1000 in 2006. Anopheles stephensi Liston is a dominant malaria vector. The monitoring of insecticide susceptibility and irritability was conducted using discriminative dose as described by WHO. METHODS The IV instar larvae were collected from diff...

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...

Although the effects of POPs on the health of free ranging loggerhead sea turtles (Caretta caretta) has been well investigated (Keller et al. 2004; Keller et al. 2006a; Keller et al. 2006b), there was only one previous study on the toxicological effects of POPs on sea turtle embryonic development (Podreka et al. 1998). However, there are a number of studies on freshwater turtles that have inves...

Epidemiological studies suggest a link between pesticide exposure and an increased risk of developing Parkinson's disease (PD). Although studies have been unable to clearly identify specific pesticides that contribute to PD, a few human studies have reported higher levels of the organochlorine pesticides dieldrin and DDE (a metabolite of DDT) in post-mortem PD brains. Previously, we found that ...

The effect of mixtures of environmental chemicals with hormonal activity has not been well studied. To investigate this phenomenon, the estrogen receptor (ER) from the American alligator (aER) or human (hER) was incubated with [3H]17beta-estradiol in the presence of selected environmental chemicals individually or in combination. The environmental chemicals included the insecticide chlordane, w...

We used filter paper contact test method for obtaining LC50 for cythion and dieldrin. This Organophosphate is very poisonous, which affects the body and Growth of Earthworm. We had seen in the test solution of 0.8mg/cm, 0.9m g/cm and 1mg/cmof 1% dieldrin, all earthworms died and melt. Similarly, cythion 0.3 and 0.27 showed the same result. This concentration was shown supertoxic to earthworms. ...

B 1963 and 1979, the carcases of 341 Sparrowhawks Accipiter nisus and 616 Kestrels Falco tinnunculus were examined at Monks Wood Experimental Station, Cambridgeshire, to find the cause of death. The carcases were sent in by members of the public, in response to advertisements in national bird journals. All carcases were requested, irrespective of region and form of death. The main objective was...

PCB and organochlorine pesticide residues were determined in otter (Lutra lutra) spraints (faeces) from nine catchment regions in SW England over the period 1989-1991. Results of analyses of tissues from 22 otters are also presented. Dieldrin occurred in the majority of spraint samples and p,p-DDE and total PCBs in all. Lindane occurred mainly in samples collected in spring. Lindane was not fou...
