The organophosphate pesticide, Ethion, remains a major environmental contaminant in rural Australia and poses a significant threat to environmental and public health. The aerobic degradation of Ethion by mesophilic bacteria isolated from contaminated soils surrounding disused cattle dip sites was investigated. Two isolates, identified as Pseudomonas and Azospirillum species, were capable of bio...

BACKGROUND The objective of this study was to determine the residual concentrations of ethion and imidacloprid in cucumbers grown in greenhouse. The effect of some simple processing procedures on both ethion and imidacloprid residues were also studied. METHODS Ten active greenhouses that produce cucumber were randomly selected. Ethion and imidacloprid as the most widely used pesticides were m...

A simple, novel and sensitive method was developed to determine ethion insecticide in water samples. This method was based on the interaction of ethion with silver nanoparticles (AgNPs) and quenching of the resonance Rayleigh scattering (RRS) intensity. The change in RRS intensity (ΔIRRS) was linearly correlated to the concentration of ethion over the range of 10.0-900.0 µg L(-1). Ethion can be...

Analyses of chlorpyriphos, ethion and dicofol in the river Deomoni from Terai region of West Bengal revealed mean pesticide residues of chlorpyriphos, dicofol and ethion in water sample as 0.0091 ± 0.0020ppm, 0.0180 ± 0.0071ppm and 0.0892 ± 0.0375 ppm, respectively, in sediments 0.0513 ± 0.0085ppm, 0.0414 ± 0.0045ppm and 0.1271 ± 0.0122ppm and in fish muscles (Puntius sp.) 5.0371 ± 1.4236 ppm, ...

The present study was designed to assess the health risk of pesticide residues via dietary intake of vegetables collected from four top agro-based markets of Dhaka, Bangladesh. High performance liquid chromatography with a photo diode array detector (HPLC-PDA) was used to determine six organophosphorus (chlorpyrifos, fenitrothion, parathion, ethion, acephate, fenthion), two carbamate (carbaryl ...

Total microbial count was highly affected (up to 61% at 1000 micrograms level) in presence of hexaconazole and persisted up to 21 days. Bacteria were more susceptible than actinomycetes. Carbofuran and ethion were moderately toxic to soil microflora. Inhibitory effects of all the three pesticides gradually decreased after 21 days as was evident by increase in total microbial count except in car...

Consumption of pesticide contaminated vegetables pose a major threat to public health. High Performance Liquid Chromatography (HPLC) with a Photo Diode Array detector (PDA) was used to determine two organochlorines (methoxychlor and DDT), seven organophosphorus (acephate, chlorpyrifos, fenthion, fenitrothion, malathion, parathion, and ethion), two carbamate (carbaryl and carbofuran) and one pyr...

   In this study, a method for extraction and preconcentration of trace amounts of organophosphorus pesticides (OPPs) in environmental water using magnetic solid phase extraction (magnetic-SPE) followed by high performance liquid chromatography (HPLC) with UV detection was developed. The magnetic carbon nanotube adsorbents (Fe3O4/CNT) were synthesized by grafting carbo...
