“…This finding shows that if pesticides are applied at recommended dosage, violation of MRL thresholds will be unlikely. These results are in agreement with previous research that showed residues of neonicotinoids in pistachio nuts were lower than their MRLs at harvest time (Dini et al 2018;Taghizadeh et al 2019;Arabameri et al 2020). According to the predicted values of the FOEG and SFOK models, effects of three multiple-spraying scenarios (see "Materials and Methods" section for more details) on the residues of IMI, THI, and THX at the harvest time (day 49) were investigated, and the results are illustrated in Figs.…”

“…Results showed that although the predicted residues exceeded MRLs in some multiple-spraying scenarios, HQ values were consistently below 1, indicating a low health hazard of pesticides for Iranian consumers. These results are in agreement with previous research, which reported no significant risk of neonicotinoid residues via pistachio consumption (Taghizadeh et al 2019;Arabameri et al 2020;Mahdavi et al 2020). Results revealed that average HQ values of all pesticides and all multiple-spraying scenarios were 1.5 and 2 times higher for children compared to teenagers and adults, respectively.…”

“…Iran is among the most prominent producers and exporters of this economically valuable horticultural crop (Dini et al 2018), with a production of 337,815 tons and a harvested area of 12,181 ha in 2019 (FAOSTAT 2019). Continuous and extensive application of insecticides such as imidacloprid (IMI), thiacloprid (THI), thiamethoxam (THX), and abamectin (ABA) is the main strategy for controlling pistachio insect pests in Iran (Faraji et al 2018;Arabameri et al 2020;Mahdavi et al 2020). As pistachio nuts are largely consumed in Iran, evaluating pesticide residues and assessing their potential dietary exposure risk for the consumers is essential.…”

“…So far, research on pesticide residues in pistachio has focused on either evaluation/optimization of analytical methods for their analysis (Faraji et al 2018;Mahdavi et al 2020) or conducting risk assessments based on terminal pesticide residues detected at harvest time (Dini et al 2018;Taghizadeh et al 2019;Arabameri et al 2020;Mahdavi et al 2020). On the other hand, there has been no research on evaluating and parametrizing statistical models for assessing field uptake/ dissipation kinetics of pesticides in pistachio nuts.…”

Pistachio is an economically valuable crop, and Iran is among the biggest producers, exporters, and consumers of this product in the world. During the growing season, pistachios are subjected to multiple sprayings with various pesticides, which result in the accumulation of their residues in nuts. These residues have raised concerns regarding consumers' health. In this research, uptake and dissipation kinetics of insecticides imidacloprid (IMI), thiacloprid (THI), thiamethoxam (THX), and abamectin (ABA) were investigated in pistachio nuts. Field experiments were conducted in a pistachio orchard. Pistachio trees were sprayed with the recommended dose of each insecticide formulation and water as the control. Samplings were performed for up to 49 days. Based on the results, pesticides uptake and dissipation kinetics were best fitted to first-order exponential growth (FOEG) and single firstorder kinetic (SFOK) models, respectively. Variations in pesticides uptake/dissipation rates were mostly related to their water solubility, pK a , and log K ow . THX showed a higher uptake rate (0.16 ± 0.04) compared to IMI (0.10 ± 0.01) and THI (0.06 ± 0.01). The fastest dissipation rates were observed for IMI (0.04 ± 0.002 day −1 ) and THX (0.03 ± 0.001 day −1 ), while the slowest belonged to THI (0.02 ± 0.003 day −1 ). ABA residues were below the quantification limit (LOQ) throughout the experiment. Based on FOEG and SFOK model predictions, multiple sprayings with THI and THX resulted in final concentrations exceeding the maximum residue limit (MRL). Hazard quotients for all pesticides were <1, indicating no risk to humans via consumption of the pistachio nut.

The aim of this study was to evaluate non‐dioxin‐like polychlorinated biphenyls (NDL‐PCBs) and the health risk from butter samples using the QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) modified method and gas chromatography/mass spectrometry (GC‐MS). A total of 60 traditional and industrial butter samples were collected from the local markets of Tehran, Iran, and were subjected to GC‐MS. The results showed that the mean concentration of total NDL‐PCBs in samples was 21.701 ± 9.02 ng/g fat. The amounts of PCBs in traditional butter samples were higher than in the industrial samples. PCB concentrations in all samples were lower than the European Union standard (40 ng/g fat). The 95th percentile incremental lifetime cancer risk of total NDL‐PCBs for children (1.79E−5) and adults (3.80E−6) was less than the acceptable risk level (10−4).
