Aldrin, p,p'-DDT, dieldrin, gamma chlordane. heptachlor, heptachlor epoxide, J-hydroxychlordene, and lindane were bioassayed against larvae of Anopheles quadrimaculatus Say; the remnant amounts of insecticide and metabolites in larvae and medium were determined by electron-affinity gas chromatography. The insecticides were surprisingly nonpersistent at concentrations normally used.
Farming and pesticide use have previously been linked to non-Hodgkin lymphoma (NHL), chronic lymphocytic leukemia (CLL) and multiple myeloma (MM). We evaluated agricultural use of specific insecticides, fungicides, and fumigants and risk of NHL and NHL-subtypes (including CLL and MM) in a U.S.-based prospective cohort of farmers and commercial pesticide applicators. A total of 523 cases occurre...
Residues of organochlorine pesticides were determined in soils and drinking water sources in cocoa growing areas in Ghana. Soil samples analysed showed the presence of four organochlorine pesticide residues namely lindane (0.005-0.05 mg/kg), beta-HCH (<0.01-0.05 mg/kg), dieldrin (0.005-0.02 mg/kg), and p,p'-DDT (0.005-0.04 mg/kg), with dieldrin occurring most frequently. Similarly, organochlori...
BACKGROUND Organochlorine insecticides (OCs) have historically been used worldwide to control insects, although most have now been banned in developed countries. Evidence for an association between OC exposures and cancer predominantly comes from occupational and population based-studies among men. We evaluated the association between the use of specific OCs and cancer among the female spouses ...
OBJECTIVE To compare the pediculicidal activity of 5 head lice products available in the United States on head lice from south Florida. DESIGN In vitro pediculicidal product comparison. SETTING Lice Source Services, Inc, located in Plantation, Fla, a clinic for the treatment and grooming of individuals with pediculosis capitis. PARTICIPANTS Head lice were collected from healthy clients wi...
American Academy of Pediatrics guidelines for the prevention and treatment of head lice infestation.
The American Academy of Pediatrics (AAP) established diagnosis and treatment guidelines for pediculosis in 2002. Ideally, diagnosis should be based on the observation of a live louse. The presence of nits is also used by many people to positively diagnose an infestation, although a nit located farther from the scalp than 1 cm is unlikely to be viable. Other material on the scalp may be mistaken...
A global multicompartment model which is based on a 3-D atmospheric general circulation model (ECHAM5) coupled to 2-D soil, vegetation and sea surface mixed layer reservoirs, is used to simulate the atmospheric transports and total environmental fate of dichlorodiphenyltrichloroethane (DDT) and γ -hexachlorocyclohexane (γ -HCH, lindane). Emissions into the model world reflect the substance’s ag...
Pandoraea sp. strain SD6-2 is a δ-hexachlorocyclohexane-degrading bacterial strain isolated from lindane-contaminated soil in Queensland, Australia. The genome of SD6-2 was sequenced to investigate its ability to degrade δ-hexachlorocyclohexane. Here we report the annotated genome sequence of this strain.
