Pesticide exposure—Egyptian scene

Toxicology, 2004
Pesticides have contributed to dramatic increases in crop yields and in the quantity and variety of the diet. Also, they have helped to limit the spread of certain diseases. But pesticides have harmful effects; they can cause injury to human health as well as to the environment.

Pesticide exposure—Indian scene

Toxicology, 2004
Use of pesticides in India began in 1948 when DDT was imported for malaria control and BHC for locust control. India started pesticide production with manufacturing plant for DDT and benzene hexachloride (BHC) (HCH) in the year 1952. In 1958, India was producing over 5000 metric tonnes of pesticides.

Biomarkers of Pesticide Exposure

1992
Incorporation of biomarkers in studies of occupational exposure hazards is now recognized as a highly useful adjunct to the surrogate measures employed in the past, for example, time worked, ambient air data, interview responses. Application to studies of workers potentially exposed to pesticides has barely begun and provides many challenges to chemist/

Pesticide exposure to greenhouse handgunners

Archives of Environmental Contamination and Toxicology, 1989
The exposure of pesticide applicators in a commercial greenhouse facility was assessed. Data were collected from four handgunners who applied fluvalinate (insecticide), chlorpyrifos (insecticide), ethazol (fungicide), and dicofol (miticide). Potential exposure was measured with exposure pads placed outside all clothing of the applicator. Handwashes and

Extraneous Pesticide Exposure

1984
Publisher Summary The greatest potential for exposure within the research and development phase is during pilot plant design and operations. Here, chemical reactions are scaled up, new technologies are tried, and larger quantities of toxic materials are present.

Conservatism in Pesticide Exposure Assessment

Regulatory Toxicology and Pharmacology, 2000
Three important factors are commonly encountered in exposure assessment that when combined could overestimate the exposure to pesticides by as much as two orders of magnitude. The three factors discussed are dermal absorption from laboratory animal studies, daily dose extrapolated from partial day monitoring, and nonbolus dose from dermal or inhalation

Environmental Equity and Pesticide Exposure

Toxicology and Industrial Health, 1993
Although people of color and low-income groups bear a disproportionate share of the health risks from exposure to pesticides, research attention has been meager, and data on acute and chronic health effects related to their toxic exposures are generally lacking.

Exposure of Spraymen to Pesticides

Archives of Environmental Health: An International Journal, 1972
Values for potential dermal and respiratory exposure, and for total exposure in terms of fraction of toxic dose were determined for 11 different pesticides during orchard spraying with air-blast application equipment. Highest total exposure was calculated to be only 1.12% of a toxic dose per hour for workers applying the organophosphorus compound ...

Residential Pesticide Exposure and Neuroblastoma

Epidemiology, 2001
Neuroblastoma is the most common neoplasm in children under 1 year of age. We examined the relation between residential exposure to pesticides and neuroblastoma, using data from a case-control study of risk factors for neuroblastoma. Incident cases of neuroblastoma (N = 538) were identified through the Pediatric Oncology Group and the Children's Cancer

Organophosphate pesticide exposure and neurodegeneration

Cortex, 2016
Organophosphate pesticides (OPs) are used extensively throughout the world. The main sources of contamination for humans are dietary ingestion and occupational exposures. The major concerns related to OP exposure are delayed effects following high level exposures as well as the impact of low level exposures during the lifespan which are suggested to be
