| Abstract | ||
| Suitable conditions bring about a high population of pests or diseases in greenhouses. Therefore, frequent pesticide application occurs in this production system, which causes public health concerns about pesticide residue in greenhouse-grown crops such as tomatoes. Residue levels of 55 pesticides were investigated in 43 greenhouse-grown tomatoes collected from four cities in Hamadan province using modified Quick, Easy, Cheap, Effective, Rugged, Safe (QuEChERS) extraction followed by GC-MS. The residue of 8 pesticides was detected in some samples. Overall, 7% of samples had residue levels above MRLs, 33% of samples had residue at or below MRLs, and 60% of the samples had no pesticide residues. The residues of methidathion (2 samples) and fenpropathrin (3 samples) were above the MRLs (0.05 mg/kg). Non-carcinogenic probabilistic risk assessment was evaluated by Hazard Quotient (HQ) and Hazard Index (HI) based on the Monte Carlo Simulation (MCS) method. The arrangement of pesticides based on HQ ranking was methidathion > cypermethrin > chlorpyrifos > fenpropathrin > diazinon > pirimicarb > metalaxyl > malathion. HI for adults was calculated to be 0.06, and for children, 0.30 in tomato. However, as HI was less than 1, consumers were not at considerable non-carcinogenic risk. | ||
