“…Yu-Shan et al (2013) confirmed that mixing sodium bicarbonate with water forms carbonic acid, can remove pesticides through oxidation. Polat & Tiryaki (2020) confirmed that acetic acid and citric acid washing treatments were more efficient than tap water treatment. Additionally, Holland et al (1994) exhibited that water solubility was the most significant parameter for pesticide residue.…”

“…Krol et al (2000) reported the efficacy of brief rinsing with water. Polat & Tiryaki (2020) confirmed that acetic acid and citric acid washing treatments are more efficient than tap water. Additionally, Rasolonjatovo et al (2017) concluded that a blend of washing solutions is more effective than a single solution in removing pesticide residues.…”

These days pesticides are extensively applied in agriculture to increase productivity; although these pesticides increase productivity but also have a negative impact on the consumer. Thus, pesticide exposure in agricultural products must be decreased. The present study attempted to assess pesticide residues in samples of apple, tomato, and brinjal and determine the efficacy of washing solutions in pesticide removal. For sample preparation, the QuEChERS method was employed, and prepared samples were analyzed using gas chromatography-mass spectrometry. Results of the study revealed that among the collected samples, 58.33 percent samples were showing lower pesticide residues as compared to the maximum residue limit (MRL) while 12.5 percent of the samples were showing higher pesticides residues as compared to the suggested MRL. Further, from the collected fruits and vegetable samples, the presence of the chlorantraniliprole, carbendazim, beta endosulfan, chlorpyrifos, malathion, carbaryl, thiomethoxam, DDT, and flubendiamide were detected in the range of 0.0–1.41 mg/kg. Among the detected pesticides, chlorpyrifos and flubendiamide were the most commonly detected pesticides. Effectiveness of different washing solutions was studied, which indicated a significant reduction in residues of all the washing solutions compared with the control (p < 0.05) and concluded that ascorbic acid and sodium bicarbonate solution was very effective in pesticides removal compared with water and chemical alone.

Pesticides are often applied with adjuvants to improve their efficacy and stability. However, the knowledge about pesticide behaviors with adjuvants is still lacking. This study investigated the impact of a common adjuvant on the persistence and penetration of dimethoate on and in apples and dimethoate stability in washing solutions using the surface-enhanced Raman spectroscopic (SERS) mapping technique. Results demonstrated that the adjuvant did not significantly affect dimethoate removal after postharvest washing or dimethoate penetration (30 ± 5 μm) in apples. Tap water showed similar effectiveness as baking soda to remove dimethoate with and without the adjuvant in 5 min. Dimethoate with and without the adjuvant was stable in tap water but was degraded to omethoate in the baking soda rapidly in 40 min. Considering the higher toxicity of omethoate, tap water would be recommended to remove dimethoate compared with baking soda. The study provides a better understanding of adjuvant effects on pesticide behaviors.

“…The QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) method (Anastassiades et al 2003) is largely employed in vegetable and fruit matrix safety analyses at well-equipped laboratories (Polat & Tiryaki, 2020). However, local laboratory conditions may require further verification for the method to be used reliably (Omeroglu et al, 2012).…”

“…In a study, chlorpyrifos residues (artificially spiked) on cucumber were reduced by 53.1, 59.2 and 62.9% with 5 ,10 and 20 min tap water washing, respectively (Liang et al, 2012). Indeed, mode of action of pesticide (systemic and/or contact) is important for reduction of residues by washing treatments (Polat &Tiryaki, 2020).…”

The aim of this study was to investigate four insecticide residues in cucumbers with the aid of QuEChERS 2007.1 method. For method verification assessment, pesticide-free cucumber matrix was spiked with 0.1, 1 and 10 times of MRL for each pesticide. The QuEChERS-LC-MS/MS analytical method revealed that the detection limits of the insecticides were below the MRLs and the overall recovery of method was 97.7%. These figures were within the SANTE recovery limits (60-140%) and the values specified for the repeatability (≤20%). Cucumbers were collected from six different stands (A-F) at Çanakkale open markets for 6 weeks between 23 November and 28 December 2018. Residues of each sampling time and each stand were assessed. Acetamiprid residue of 257g and 236 µg/kg were detected in week 5 from stand B and in week 2 from stand E, respectively. These values are close to MRL (300 µg/kg). Formetanate hydrochloride residue of the week 3 from stand F (36.3 µg/kg) was more than MRL of 10 µg/kg. Pirimiphos methyl and chlorpyrifos residues were not detected in cucumbers. Theoretical maximum daily intake assessment showed that there was no chronic exposure risk for these four pesticides through cucumber consumption.
