Two hundred and fifteen green beans samples from an agricultural region of the Souss (Agadir, Morrocco) were analyzed for endosulfan, dithiocarbamate, bifenthrin, chlorothalonil, iprodion, procymidon and deltamethrin. Of 189 samples that contained pesticide residues, dithiocarbamates (mancozeb and mefenoxam) were detected in 43 (20 %) in the concentration range of 0.045 to 2.651 mg Kg-1. Four o...

Residue Number Systems require the selection of ring moduli whose product is greater than the predicted dynamic range of the computation being performed. The restriction that the moduli be relatively prime usually limits the set of available moduli and hence the maximum dynamic range. This is particularly the case when small moduli are to be considered for efficient hardware implementation. Sev...

Every year lots of black tea (Camellia sinensis (L.) Kuntze) residue will produce in the factories. These residue are unusable whereas the bio active compounds can be extracted and used in the drag and food industries. Due to mentioned problems, this project was conducted years 2011 - 2012 with the aim to make a study on consecutive isolation of all bio active compounds from tea residu...

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. ...

In this study, the level of selected organophosphorus and organochlorine pesticide residues from water samples of Gilgle Gibe (I) hydroelectric dam reservoir and its potential tributaries, Jimma zone, Ethiopia, was determined by gas chromatography-electron capture detector (GC-ECD). Low density based dispersive liquid-liquid microextraction (LD-DLLME) using toluene (as extractant) and acetonitr...

Pesticides have been worldwide used for the protection of food crops against pests and diseases. It is common that residues of these pesticides occur in food products, especially agricultural commodities. Adverse effects on human health of pesticides residues remaining in food after they are applied to food crops are generally known. Possible health risk due to pesticide residues in the diet ha...
