Evaluation of organophosphorus pesticide Diazinon residue in greenhouse crops using spectrophotometry (Case Study: Mushroom)
Abstract
Pesticides are among the chief sources of environmental pollutants that have impacts on living creatures and humans health. The purpose of this study was to evaluate the concentration of organophosphorus pesticide Diazinon residues in mushroom using Spectrophotometry. A total number of 10 mushroom samples was collected from the active greenhouses around Hamedan city as well as commercial brands that present their products in Hamedan retails. The samples were prepared and Diazinon residue in samples was read by Spectrophotometer in 3 replicates. Mean value of Diazinon concentration in different commercial brands was estimated at 0.126, 0.125, 0.166, 0.040, 0.130, 0.081, 0.129, 0.132, 0.128 and 0.129 mg/kg that were above the Europe Union Maximum Residue Limit (MRL). Moreover, the comparison of results achieved from the different samples show significant different between greenhouses of 3, 4 and 6 (p>0/05). It was concluded that training of farmers to use appropriate amounts of pesticides would guaranty the safety and health of consumers of agriculture products.
