“…In day 0 grape samples, such reduction rates were 77, 86 and 89%. Zhou et al (2019) investigated the efficiency of different washing treatments in reduction of pesticide residues and found that ultrasonic washing more efficient than tap water treatment. Buakham et al (2012) also reported greater reductions with ultrasonic washing.…”

“…Researchers have mostly focused on efficient means of pesticide residue reduction from fruits and vegetables. Majority of them employed washing treatments with tap water and reported some positive outcomes with washing (Zhou et al, 2019;Corrias et al, 2020). Heshmati et al (2020) worked on residues of some pesticides in unwashed and washed grapes and reported decreased residues with washing treatments.…”

“…Researchers reported that NaHCO3 treatments yielded about 95% reduction for diazinon, 95% reduction for penconazole, 94% for hexaconazole, 72% for ethion and 63% for phosalone. However, Zhou et al (2019) reported that ultrasonic cleaning was the most efficient means of residue reduction in grape samples with reduction of 72-100%. These different degrees of reduction can be attributed to surface structure of the matrix.…”

“…While some researchers used tap water, the others used acetic acid and ultrasonic cleaning processes for reduction of residues from fruits and vegetables (Khadre et al, 2001;Lozowicka et al, 2013;. Previous research also focused on reduction of residue levels with different food processing techniques (Randhawa et al, 2104a;Lozowicka et al, 2016;Zhou et al, 2019;Heshmati et al, 2020). Osman et al (2014) reported that washing with acetic acid and citric acid (1-2%) was more efficient for reduction of insecticide (chlorpyrifos) residues than the other procedures, such as tap water washing and KMnO4 and H2O2.…”

Insecticide application is the most common method of insect control in agriculture. Efficiency of washing treatments in reduction of insecticide (chlorpyrifos-methyl and lambda-cyhalothrin) residues from grapes were investigated in this study. The trial was established in a Sultana seedless vineyard in Sarıgöl District, Manisa Province, Turkey in 2020. Method verification was performed with the recovery, limit of quantification and precision. Pesticidefree grapes were spiked with 0.5, 1 and 5 times of MRL for pesticides. The recovery of chlorpyrifos-methyl and lambdacyhalothrin were 102 and 101% respectively. QuEChERS method yielded an overall-recovery of 101%. These figures were within the SANTE recovery limits (60-140%) and the detection limits of the insecticides were below the MRLs. Grapes in a vineyard were sprayed with insecticides four times and harvested 0, 2, 4 and 7 d after the last spray. Washing (tap water, citric and acetic acid) and ultrasonic cleaning treatments were applied to harvested grapes. Washing treatments decreased residue levels and reductions increased with prolonged washing durations. Reductions also decreased with prolonged harvest durations from the last spray. The citric and acetic acid washing, and ultrasoniccleaning methods provided more efficient reduction than washing with tap water.

“…Abamectin B 1 , is the only avermectin that is widely approved for plants and animals for its e cient antiparasitic activity 2,3 . However, wide use of avermectins usually leads to consecutive accumulation in food-producing animals and plants 4,5 . To detect avermectins (Abamectin B 1 ), various analytical approaches were used.…”

The development of detecting residual level of abamectin B1 in apples is of great importance to public health. Herein, we synthesized a octopus-like azobenzene fluorescent probe 1,3,5-tris (5'-[(E)-(p-phenoxyazo) diazenyl)] benzene-1,3-dicarboxylic acid) benzene (TPB) for preliminary detection of abamectin B1 in apples. The TPB molecule was characterized by ultraviolet-visible absorption spectrometry, 1H-nuclear magnetic resonance, fourier-transform infrared (FT-IR), electrospray ionization mass spectroscopy (ESI-MS) and fluorescent spectrum. A proper determination condition was optimized, with limit of detection and limit of quantification of 1.3 µg L-1 and 4.4 μg L-1, respectively. The mechanism of this probe to identify abamectin B1 was illustrated in terms of undergoing aromatic nucleophilic substitution, by comparing fluorescence changes, FT-IR and ESI-MS. Furthermore, a facile quantitative detection of the residual abamectin B1 in apples was achieved. Good reproducibility was shown based on relative standard deviation of 2.20%. Six carboxyl recognition sites, three azo groups and unique fluorescence signal towards abamectin B1 of this fluorescent probe decided ideal sensitivity, specificity and selectivity. The results show that the octopus-like azobenzene fluorescent probe may be promising for evaluating abamectin B1 in agricultural foods.

Dendrobium officinale, a minor crop with medicinal and edible value, is increasingly consumed by people, but the pesticide residues on it have received little attention. In this work, field trials were conducted under good agricultural practice conditions to investigate the residues of chlorothalonil, SDS‐3701, metalaxyl, and dimethomorph in D. officinale; then the evolution of these pesticides after household processing was studied. The results indicated that chlorothalonil, SDS‐3701, metalaxyl, and dimethomorph were 2.41–30.12, 0.20–1.23, 0.07–0.80, and 0.19–7.90 mg kg−1, respectively, in stems at recommended preharvest interval (30 days). Washing and soaking removed the pesticides in fresh stems with processing factors 0.41–1.14 and 0.12–1.13, respectively. In the brewing test, the transfer rates of pesticides in dry stems decreased from the first time (4.27–95.40%) to the third time (3.89–15.57%). Intake risk assessments were also conducted, and the risk quotients were no more than 27.02% for all compounds in different samples, which indicated acceptable risks for consumers. As effective risk‐reducing home‐processing methods, washing, soaking, and multiple brewing were suggested in this work, hoping to help consumers with diet safety.
