“…The ADIs obtained from the literature are described in the Table 4 [19,20]. The EDI (mg kg/bw/day) was calculated by multiplying the pesticide concentrations of each pesticide (mg/kg) and the food consumption rate (kg/day) and dividing this by the body weight (bw) [40,41]. The body weight data was taken from 2009-2010 Chilean National Health Survey (ENS) conducted in 2009-2010 [42].…”

Over the last years, the detection of pesticide residues in the official food surveillance programs of Chile has been increased, mainly in fresh vegetables such as tomatoes and lettuces. The Metropolitana Region of Chile presents the highest detections in the country. The lack of evaluations of toxicological risks in human health have increased uncertainty of the potential effects of pesticides exposures in the Chilean population. This research aims to determinate health risks assessment of pesticide residues associated to tomatoes and lettuces produced in Metropolitana Region. The findings of this study reveal that tomatoes and lettuces cultivated in the MR show more than 50% of samples with one or multiple pesticides residues. From the total samples, 16% were over the Chilean Maximum Residue Levels (MRLs). The main pesticides detected in tomatoes and lettuces were methamidophos, methomyl, difenoconazole, cyprodinil and boscalid. The results obtained using the official data of the Ministry of Health of Chile (MINSAL) compared to the World Health Organization (WHO), describe relevant risks through the Estimated Daily Intakes (EDI), Hazard Quotients (HQ) and Hazard Index (HI) for the Chilean population due to high concentrations of methamidophos, methomyl and cyprodinil. More restrictions for the use of methamidophos, methomyl, difenoconazole, cyprodinil and boscalid and effective control programs should be implemented in order to mitigate the impacts on the Chilean population.

“…Furthermore, an index (%) >100 indicates the possibility that the exposure would induce obvious toxic effects [24]. The HI was calculated with the HQs summed up for all the pesticides considered neurotoxic [40,41]. HI = i n=1 HQn.…”

“…A HI value is greater than 1 indicates that the concerned commodity should be considered a risk to the consumers, whereas an HI index below 1 indicates that its consumption should be considered safe (El Hawari, Mokh, Al Iskandarani, Halloum, & Jaber, 2019;Gad Alla, Loutfy, Shendy, & Ahmed, 2015;Reffstrup, Larsen, & Meyer, 2010).…”

“…A study in Egypt reports cumulative hazard indices for organophosphates higher than those of pyrethroids but both of them below one (Gad-Alla et al, 2015;Thabet, Shendy, & Gadalla, 2016). Usually, in Arusha district, vegetables are prepared for consumption for the entire family including children and pregnant women who are reported to be more vulnerable to health risks associated with exposure to pesticide residues than other groups of the population (FAO/WHO, 2009).…”

This study was conducted to assess dietary exposure to pesticide residues and pesticide application practices leading to the presence of these residues among vegetable farmers in Arusha, Tanzania. Face-to-face interviews using semi-structured questionnaires (including 24-hour recall and food frequency questionnaire techniques) were conducted to collect information on pesticide application practices and vegetable consumption, from 76 farmers. A sample of ready-to-eat vegetables was collected from each farmer's household to determine the level of pesticide residues. Pesticide residues were analyzed by gas chromatography-mass spectroscopyA deterministic approach was used to assess dietary exposure to pesticide residues. Among the analyzed samples, 31.4% contained detectable levels of organophosphate residues. The detected organophosphates were dimethoate (mean, 8.56 mg kg-1), acephate (mean, 2.9 mg kg-1), profenofos (mean, 8.44 mg kg-1), dichlorvos (mean, 20.8 mg kg-1) and malathion (mean, 5.47 mg kg-1). The mean exposure for dimethoate (0.0021 mg kg-1 body weight (wt) day‑1 was higher than its corresponding acceptable daily intakes of 0.002 mg kg-1bwd‑1 resulting in hazard quotient of 1.044 with a consequent hazard index of 1.19 for organophosphates. Pyrethroid pesticides (permethrin, cypermethrin, and lambda-cyhalothrin) were also detected but at a lower frequency (17.1%) and hazard index (0.029). The exposure to pesticide residues was significantly associated with limited access to expert advice on pesticide application (p=0.031, adjusted odds ratio=6.56) and over-dosage (p=0.038, adjusted odds ratio=3.751).The risk may be minimized by increasing access to support by extension service providing guidance on good practices and ensuring application of appropriate doses for pesticides.
