In the present study, the residual pesticide levels were determined in eggplants (Solanum melongena) (n = 16), purchased from four different markets in Dhaka, Bangladesh. The carbamate and organophosphorus pesticide residual levels were determined by high performance liquid chromatography (HPLC), and the efficiency of gamma radiation on pesticide removal in three different types of vegetables w...
background: since organophosphorus pesticides are widely used for industry and insect control in agricultural crops, their fate in the environment is very important. pesticide contamination of surface water has been recognized as a major contaminant in world because of their potential toxicity towards human and animals. the objective of this research was to investigate the influence of variou...
Pesticide residues analysis in Iranian fruits and vegetables by Gas Chromatography-Mass Spectrometry
Pesticide residues in fruits and vegetables are one of the highest concerns of consumers who need food safety. In this study, forty-eight pesticide residues from different chemical structure including organochlorine, organophosphorus, organonitrogen, dicarboximides, strobilurin, triazine, pyrethroids and other chemical groups. in 85 fruits and vegetables were determined and confirmed by GC-MS. ...
A survey of pesticide residues in 316 baby foods on the Tokyo market from April 1999 to June 2005 was carried out. Fifteen kinds of pesticides, including organophosphorus, organochlorine, carbamate, pyrethroid and others, were detected between at levels Tr (below 0.01 ppm) and 0.55 ppm from 28 samples. The baby foods in which residual pesticides were detected were produced from flour, leaf vege...
Residential proximity to applications of agricultural pesticides may be an important source of exposure to agents that have been classified as developmental toxins. Data on two case-control study populations of infants with neural tube defects (NTDs) and nonmalformed controls delivered in California between 1987 and 1991 were pooled to investigate whether maternal residential proximity to appli...
The recent report on acute organo-phosphorus pesticide poisoning, oxidative damage, haemoglobin level and total leukocyte is very interesting. Hundekari et al. noted that “cholinesterase inhibition may initiate cellular dysfunction leading to acetylcholine induced oxidative damage.” This work is very useful information in clinical toxicology. However, there are many points to be considered. Fir...
Agilent Technologies Inc. has implemented new testing procedures to more effectively evaluate GC column inertness performance. This new testing procedure employs deliberately aggressive probes to thoroughly investigate and verify column inertness and quality. In challenging separations, knowing that the GC column has been thoroughly investigated for column inertness gives analysts higher confid...
The use of organophosphorus pesticides results in toxicity risk to non-target organisms. Organophosphorus compounds share a common mode of action, exerting their toxic effects primarily via acetylcholinesterase (AChE) inhibition. Consequently, acetylcholine accumulates in the synaptic clefts of muscles and nerves, leading to overstimulation of cholinergic receptors. Acute cholinergic crisis imm...
