OBJECTIVE Prenatal exposure to organophosphate pesticides can lead to developmental neurotoxicity. A longitudinal birth cohort was established to investigate pesticide exposures from different agricultural activities. Maternal urinary organophosphate metabolites were measured at 28 weeks of pregnancy (n=86), delivery (n=67) and 2 months postpartum (n=51). METHOD Subjects were interviewed with...

The fisheries products in this study comprise fish, bivalve, crustacean and cephalopod collected from different types of markets in Taiwan between the years 2001 and 2003. A total of 91 pesticide residues belonging to four major pesticide groups were tested and analyzed. The test results show that 65.40% of fish, 93.55% of shellfish, 84.92% of crustacean and 98.33% of cephalopod samples contain...

diazinon pesticide and its metabolites have been identified in aquatic systems worldwide. it was related to toxicity for aquatic organisms, animals, and humans. waters contaminated with such persistent insecticides should be treated with suitable treatment processes. in this research, diazinon removal from aqueous solutions by the photo–fenton–like process (uv/h2o2/fe0) was investigated. this e...

OBJECTIVES To measure the exposure of a group of farmers to organophosphate pesticide in sheep dip, and to record the incidence of symptoms after exposure. DESIGN A prospective study of the autumn 1992 dipping period. Working methods were assessed by questionnaire. Absorption of organophosphate pesticide was estimated before, immediately after, and six weeks after dipping by measuring plasma ...

PURPOSE To study the possible potentiation of the carcinogenic effects of ultraviolet radiation associated with an organophosphate pesticide. METHODS Forty Wistar rats were assigned into four groups (n=10 each) randomized according to the procedures: group A received only UVR-B radiation; group B, UVR-B for eight weeks followed by a seven week period of pesticide exposure; group C, UVR-B + pe...

background: agriculture is an important sector for the malaysian economy. the use of pesticides in agriculture is crucial due to its function in keeping the crops from harmful insects. children living near agricultural fields are at risk of pesticide poisoning. objective: to evaluate the genotoxic risk among children who exposed to pesticides and measure dna damage due to pesticides exposure. m...

Organophosphates are mainly used as pesticides to protect crops from pests. Because organophosphate pesticides’ use has expanded dramatically worldwide, accurate monitoring of their concentrations in the environment and food become utmost importance. Once considered acutely toxic due acetylcholinesterase inhibition, nowadays organophosphates classified extremely dangerous compounds, with a broa...

Background: Organophosphate pesticide (OP) exposure may be associated with the subsequent development of cognitive decline, which is used to assess early stage Alzheimer’s disease. We investigated correlations between biomarkers OP and decline among farmers nonfarmers.

BACKGROUND The Agricultural Health Study (AHS) is a prospective cohort study of licensed pesticide applicators from Iowa and North Carolina enrolled 1993-1997 and followed for incident cancer through 2002. A previous investigation in this cohort linked exposure to the organophosphate fonofos with incident prostate cancer in subjects with family history of prostate cancer. OBJECTIVES This find...
