“…This is consistent with previous studies in which pesticides were detected in a whole food basket including yam at concentrations below the MRLs (Adeyeye and Osibanjo 1999;Asiedu 2013;Bempah and Donkor 2011;Kolani et al 2016;Yang et al 2016). Other studies show similar results (Blasco et al 2006;Lozowicka et al 2015;Osibanjo and Adeyeye 1995;Su et al 2003).…”

“…The recovery studies revealed that the QuEChERS method is an efficient method for multi-residue analysis of the tested pesticides in yam. The recoveries of all the 25 pesticides analyzed were well within the 70% -120% performance criteria (Bempah and Donkor 2011;Berrada et al 2010;Gilbert-López et al 2010;Lesueur et al 2008;Lozowicka et al 2015;Mekonen et al 2014;Nguyen et al 2008;Osman et al 2010) These recoveries indicate that the method used is reproducible. In terms of accuracy and precision i.e.…”

Pesticides residue analysis in yam from selected markets across Ghana and Belgium: an evaluation of the QUECHERS method

Background: In recent years, concerns have been raised in Ghana regarding the use of pesticides in yamproduction to the extent that it is feared that pesticides residues may be found in the yam tuber which isconsumed by many Ghanaians. This present study, therefore, was designed to assess the level of pesticides residues in yam bought from across Ghanaian markets i.e. production for local consumption and from Belgium grocery shops (export production from Ghana) using the Quick, Easy, Cheap, Efficient, Rugged and Safe (QuEChERS) method coupled with LC-MS/MS. A total of 180 yam samples, including 150 from Ghana and 30 from Belgium were collected and pesticides residues were analyzed using a multi-residue method. Results: A total of 25 pesticides were screened in the yam samples and 11 of them were detected. Theresults indicated that about 46% of the samples contained one or more of the 11 detected pesticides in arange of 0. 000014 mg/kg up to 0.0146 mg/kg. The three most detected pesticides in this study were fenpropimorph, cadusafos and fenitrothion, occurring in 179, 171 and 126 samples respectively. All the detected pesticides were below their respective EU maximum residue limits (MRL). Conclusion: By these results, it can be said that, the residues of the monitored pesticides found in yam arevery low and are unlikely to pose a negative human health effect.

“…Tomatoes are sensitive to pests hence require multiple use of pesticides which can be found as residues if not properly used. In Kazakhstan, Lozowicka et al (2015) detected up to nine pesticide residues including azoxystrobin, metalaxyl, flusilazole and triadimefon. Multiple contamination increases health risks as there could be a possibility of synergism in their effects.…”

Tomato pesticides health risk was assessed in Meru district of Arusha region, one of the key tomato producers in Tanzania. Tomato samples and consumption information were collected from 50 farmers using Food and Drug Administration standards and twice administered twenty-four hour recall questionnaire respectively. Analysis for pesticide residues was done using Gas Chromatography Mass Spectrometry. Dietary pesticide exposure was estimated deterministically by combining pesticide residue levels and tomato consumption levels. Pesticide levels were detected for; permethrin (mean, 5.2899 mg/kg/day), chlorpyrifos (mean, 7.5281 mg/kg/day) and ridomil (mean, 2,854.279 mg/kg/day) in 18% of samples. Health Risk Indices, determined as ratio of estimated daily intake to acceptable daily exposure, for chlorpyrifos, permethrin and ridomil were greater than one. This implies that, lifetime consumption of fresh tomatoes can pose health risk for chlorpyrifos, permethrin and ridomil. Awareness raising on good practices for pesticide application and food safety strengthening are recommended to protect public health against pesticides. This paper has explored pesticide application practices during tomato production and its implication to pesticide residues and the associated risks of dietary pesticide exposure.It has been found that, pesticide residues found in tomatoes are higher than the recommended limits and might cause health risks to consumers. These findings will provide evidence for policy makers to develop strategies of reducing risk to consumers and serve as a basis of training farmers on pesticide use as well as strengthen food safety system in Tanzania. In the long run, safe tomatoes will be consumed and the public will be protected from any fatal health risks associated with pesticides exposure.This will consequently, promote health and nutrition wellbeing of tomato consumers in Tanzania and the nearby countries.

“…The incidence of pesticide residues in the tested vegetables may be due to vegetable crops being damaged by many pests and their various species [17,18] (Table 4); therefore, different pesticides are applied to protect these crops against pests and diseases, particularly vegetable crops that are cultivated under greenhouse conditions [19,20]. The humid conditions and large amount of food in greenhouse environments make them ideal habitats for pests and make crops in these environments more susceptible to pests such that successive applications of pesticide treatments are required to prevent considerable crop losses [21,22]. The highest concentrations of detected pesticides were recorded for the fungicide cyproconazole (in chili pepper), followed by the insecticide profenofos (in cabbage), the fungicide myclobutanil (in cucumber), the fungicide metalaxyl (in tomato), and the insecticide methomyl (in eggplant).…”

Evaluation of Pesticide Residues in Vegetables from the Asir Region, Saudi Arabia

This study's aim was to determine the pesticide residues in 10 different vegetable commodities from the Asir region, Saudi Arabia. We evaluated 211 vegetable samples, collected from supermarkets between March 2018 and September 2018, for a total of 80 different pesticides using ultrahigh-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) and gas chromatography-tandem mass spectrometry (GC-MS/MS) after extraction with a multi-residue method (the QuEChERS method). The results were assessed according to the maximum residue limit (MRL) provided by European regulations for each pesticide in each commodity. All lettuce, cauliflower, and carrot samples were found to be free from pesticide residues. A total of 145 samples (68.7%) contained detectable pesticide residues at or lower than MRLs, and 44 samples (20.9%) contained detectable pesticide residues above MRLs. MRL values were exceeded most often in chili pepper (14 samples) and cucumber (10 samples). Methomyl, imidacloprid, metalaxyl, and cyproconazole were the most frequently detected pesticides. Based on the results of this study, we recommend that a government-supported program for the monitoring of pesticide residues in vegetables be established to promote consumers' health and achieve sustainable farming systems.
