“…The half-lives of chlorfenapyr estimated in this study were similar to or slightly lower than those reported in previous studies on strawberries (4.68 days), sweet persimmons (8.8 days), and various vegetables (1.2–9.8 days) [ 7 , 16 , 28 , 29 ]. The half-lives of cyenopyrafen were previously reported to be 5.2–9.8 days in Asian pears [ 30 ] and 7.99–12.65 days in grapes [ 31 ], which are similar to our current study. The half-lives of indoxacarb were reported to be 3.0–3.8 days in eggplants, 3.12–3.21 days in tomatoes, 3.46–4.77 in green chilis, 7.4–8.4 days in pomegranate fruits, and ranging from 20 to 24 days in apples [ 32 , 33 , 34 , 35 , 36 ].…”

“…The half-lives of spirotetramat were reported as 1.30–1.90 days in chilis, 5.6–7.6 days in grapes, and 4.7–9.6 days in citrus, which are shorter than those observed in this study [ 37 , 38 , 39 , 40 ]. These results suggest that many factors could influence the degradation of pesticides, such as their physical and chemical properties, environmental conditions, crop species, and growth dilution factors [ 30 , 41 ].…”

The dissipation patterns of chlorfenapyr, cyenopyrafen, indoxacarb, and spirotetramat on strawberries and the effects of different household washing methods were investigated. A risk assessment was also conducted by monitoring the insecticide residues detected. The concentrations ranged from 0.011 to 0.27 mg/kg for chlorfenapyr, 0.064 to 0.99 mg/kg for cyenopyrafen, 0.042 to 0.53 mg/kg for indoxacarb, and from 0.25 to 1.3 mg/kg for spirotetramat, which were all below the maximum residue limits (MRLs) reported. Soaking the fruit in solution and then rinsing with running water (B) led to better residue removal (40.9 ± 23.7%) than only soaking in solution (A) (24.7 ± 22.5%). However, neither method decreased chlorfenapyr concentrations, suggesting that the physical–chemical properties of chlorfenapyr could also affect its removal on strawberries. Regarding the different washing solutions in method B, 3% vinegar (removal efficiency: 48.7%) and 3% salt (45.7%) were the most efficient, followed by 3% green tea (38.9%), and tap water only (24.6%). Additionally, the estimated risk quotients (RQs) for strawberry consumption for women were about 1.5 times higher than those observed for men, but both were lower than 1, suggesting minimal risk to humans.

“…Tandem mass spectrometry is a selective and sensitive technique than can identify the compound based on molecular structure, compared with the false positive results of a conventional LC detector (Kabir, Abd El‐Aty, Kim, et al, ). Mass confirmation was determined using tandem mass spectrometry (LC–MS/MS) to justify the dimethomorph peak obtained from LC‐UVD.…”

Residue analysis of dimethomorph in Swiss chard cultivated at two different locations under greenhouse conditions was conducted using high-performance liquid chromatography-ultraviolet detection and confirmed by tandem mass spectrometry. The randomly collected samples (over 14 days) were extracted with acetonitrile and purified using a Florisil solid-phase extraction cartridge. Linearity over a concentration range of 0.05-50.0 mg/L had an excellent coefficient of determination of 0.9996. Recovery rate ranged from 82.98 to 95.43% with relative standard deviations ≤5.12% and limits of detection and quantification of 0.003 and 0.01 mg/kg, respectively. The initial deposits [day 0 (2 h post-application)] were considerably lower (7.57 and 8.55 mg/kg for sites 1 and 2, respectively) than the maximum residue limit (30 mg/kg) set by the Korean Ministry of Food and Drug Safety. The dissipation half-life was approximately the same, being 5.0 and 5.1 days for sites 1 and 2, respectively. Risk assessment estimated as acceptable daily intake revealed a value of 0.084 or 0.094% (day 0) and 0.014% (10 days post-application), for sites 1 and 2, respectively. The values indicated that dimethomorph can be safely used on Swiss chard, with no hazardous effects expected for Korean consumers.

“…The acceptable daily intake (ADI) of sulfoxaflor is 0.051 mg (Table ). The estimated daily intake can be calculated from the following equation: Estimated daily intake (EDI) = residue amount × average uptake (Kabir et al, ; Lee et al, )

ADI (() %) = EDI / ADI \times 100

The dissipation pattern of sulfoxaflor in Asian pear cultivated in an open field conditions and in oriental melon grown under plastic house conditions was each studied in two different locations. Residues in field-treated samples were determined using liquid chromatography coupled with an ultraviolet detector and confirmed by liquid chromatography-tandem mass spectrometry. A calibration curve for sulfoxaflor was linear over the concentration range 0.1-5.0 mg/L, with a coefficient of determination of 0.9999. The limits of detection and quantification (LOQ) were 0.007 and 0.02 mg/kg, respectively. Recoveries at three fortification levels (LOQ, 10 × LOQ and maximum residue limit) ranged from 70.5 to 86.2%, with a relative standard deviation ≤5.8%. The dissipation half-lives were 10.8 and 7.9 days in pear and 5.4 and 5.9 days in oriental melon, at sites 1 and 2, respectively. Based on a pre-harvest residue limit curve, it was predicted that, if the residues at 10 days before harvest in Asian pear are <0.54/0.61 mg/kg and those in oriental melon are <1.43/1.26 mg/kg, then the residue level will be below the maximum residue limit at harvest. Risk assessment at zero days showed a percentage acceptable daily intake of 10.80% in Asian pear and 1.77 and 1.55% in oriental melon, for sites 1 and 2, respectively. These values indicate that the fruits are safe for consumption.
