The present study was undertaken to detect and quantify the left over residue of Diazinon and Carbosulfan in brinjal and Quinalphos in yard long bean and comparison between the detected residue level with maximum residue level (MRL) set by FAO (1970). Three supervised field trials (two for brinjal and one for yard long bean) were carried out sprayed with the field dose (1.5 ml/L of water) of Di...

The aim of this study was to evaluate the genetic damage in human peripheral blood lymphocytes following 24 and 48- hour exposure to a commercial diazinon formulation Basudin 60EM® at concentrations between 0.01 and 40 μg mL-1. For this purpose we used the micronucleus (MN), fluorescence in situ hybridization (FISH), and alkaline single cell gel electrophoresis (comet) assay. Diazinon significa...

Homogeneous liquidliquid microextraction; Flotation assistance; Diazinon; Water samples ABSTRACT: In the present study a sensitive method for extraction of diazinon in water samples was developed using homogeneous liquid-liquid microextraction via flotation assistance (HLLMEFA). Toluene at microliter volume level was used as extraction solvent. The main advantages of method are high enrichment ...

Genetic evidence suggests that the evolution of resistance to the insecticide diazinon in Lucilia cuprina initially produced an increase in asymmetry. At that time resistant flies were presumed to be at a selective disadvantage in the absence of diazinon. Subsequent evolution in natural populations selected modifiers to ameliorate these effects. The fitness and fluctuating asymmetry levels of r...

ABSTRACTDiazinon has a hepatotoxic effect since it is metabolized in the liver involving Kupffer cells (KCs) activation, increasing reactive oxygen species (ROS). The flavonoids contained shallot (Allium cepa L.) skin act as antioxidants neutralizing oxidative stress. This study aims to determine of ethanol extract (SSEE) on MDA level and activated KCs histopathology. total SSEE was measured us...

We have measured 29 pesticides in plasma samples collected at birth between 1998 and 2001 from 230 mother and newborn pairs enrolled in the Columbia Center for Children's Environmental Health prospective cohort study. Our prior research has shown widespread pesticide use during pregnancy among this urban minority cohort from New York City. We also measured eight pesticides in 48-hr personal air...

On a goose farm with 7600 geese kept in 6 houses, 730 birds in 2 houses died within a single day. After drinking, a certain proportion of geese in the affected houses exhibited trembling, salivation, lachrymation and respiratory distress followed by convulsions, dullness and prostration. The birds died soon after the onset of clinical signs. Postmortem examination revealed the presence of a lar...

Pesticide exposure has repeatedly been associated with cancers. However, molecular mechanisms are largely undetermined. In this study, we examined whether exposure to diazinon, a common organophosphate that has been associated with cancers, could induce DNA methylation alterations. We conducted genome-wide DNA methylation analyses on DNA samples obtained from human hematopoietic K562 cell expos...

Widespread contamination of California water bodies by the organophosphate insecticides diazinon and chlorpyrifos is well documented. While their usage has decreased over the last few years, a concomitant increase in pyrethroid usage (e.g., permethrin) (replacement insecticides) has occurred. Vegetated agricultural drainage ditches (VADD) have been proposed as a potential economical and environ...

The recent (late 2001) federally mandated phaseout of diazinon and chlorpyrifos insecticide use in outdoor urban settings has resulted in a rapid decline in concentrations of these insecticides in urban streams and rivers in the northeastern and midwestern United States. Assessment of temporal insecticide trends at 20 sites showed that significant step decreases in diazinon concentrations occur...
