“…The sensitivity of liquid chromatography (LC) method for the determination of Alternaria toxins is too low to meet the analytical requirements. Therefore, liquid chromatography–mass spectrometry (LC–MS) method is the mainstream method for the analysis of mycotoxins 25‐27 . From the reported literature, the LC–MS method has been used for the detection of Alternaria toxins in agriculture, the environment, medicine and other fields 28‐31 .…”

“…Therefore, liquid chromatography-mass spectrometry (LC-MS) method is the mainstream method for the analysis of mycotoxins. [25][26][27] From the reported literature, the LC-MS method has been used for the detection of Alternaria toxins in agriculture, the environment, medicine and other fields.

BACKGROUNDAlternaria can infest pears to produce metabolites, which can contaminate pears and their processed products. Pear paste, one of the most important pear‐based products, is popular among Chinese consumers especially for its cough relieving and phlegm removal properties. Although people are concerned about the risk of Alternaria toxins in many agro‐foods and their products, little is known about the toxins in pear paste.RESULTSA method was developed for the determination of tenuazonic acid, alternariol, alternariol menomethyl ether, altenuene and tentoxin in pear paste by ultra‐performance liquid chromatography tandem mass spectrometry with saturated sodium sulphate dissolution and acidified acetonitrile extraction. The mean recoveries of the five toxins were 75.3–113.8% with relative standard deviations of 2.8–12.2% at spiked levels of 1.0–100 μg kg−1. Alternaria toxins were detected in 53 out of 76 samples, with a detection rate of 71.4%. Tenuazonic acid (67.1%), alternariol (35.5%), tentoxin (23.7%) and alternariol monomethyl ether (7.9%) were detected in all samples at concentrations of < limit of quantification (LOQ)–105.0 μg kg−1, < LOQ–32.1 μg kg−1, < LOQ–74.2 μg kg−1 and < LOQ–15.1 μg kg−1, respectively. Altenuene was never found in pear paste samples. Tenuazonic acid, alternariol, tentoxin and alternariol menomethyl ether should be focused on due to their toxicity and detection rates.CONCLUSIONTo the best of our knowledge, this is the first report on the detection method and residue levels of Alternaria toxins in pear paste. The proposed method and research data can provide technical support for the Chinese government to continuously monitor and control Alternaria toxins in pear paste, especially tenuazonic acid. It can also provide a useful reference for related researchers. © 2023 Society of Chemical Industry.

“…However, no long-term health risks to consumers were identified [66]. Similarly, risk assessments of pesticide residues in vegetables in many regions have indicated acceptable levels of chronic risks [67][68][69][70][71][72]. In this study, the chronic dietary risk of greenhouse leafy vegetables was acceptable even during the cold seasons in the temperate zone of northeast China.…”

Excessive pesticide application in greenhouses leads to elevated levels of pesticide residues, especially in cold seasons, thereby posing a potential dietary exposure risk to the residents’ health. This study aimed to investigate 65 pesticides in 469 leafy vegetable samples collected from greenhouses in Liaoning province between October 2018 and May 2020. Overall, the pesticide levels in 96.4% (452/469) of the samples were below the MRLs established by the Codex Alimentarius Commission. The detection rate of 65 pesticides ranged from 0.2% to 11.9%. Multiple pesticide contamination was common, with dimethomorph being the most recurrent contaminant. The dietary risk assessment study revealed obvious differences in chronic and acute exposure risk values. The chronic risk quotients (RQcs) for leafy vegetable samples were 0.001%–3.993%, indicating an acceptable public health risk for the residents. As two leafy vegetables highly consumed in cold seasons in northeast China, the acute risk quotients (RQas) of Chinese cabbage samples were significantly lower than 100%; however, pakchoi samples exhibited RQa values ranging from 0.159% to 580.529%, showing an unacceptable acute dietary risk. This highlights that, compared to the chronic dietary risks, the potential acute dietary risks induced by the pesticides are higher in greenhouse-grown leafy vegetables during cold seasons.

“…Dietary risk assessment is of great significance for the establishment of MRL and the regulation of pesticides. 24 In this experiment, Eqns (4) and ( 5) were used to calculate the chronic risk quotient (RQ), which made it easy to assess the RQ of bisultap in citrus. Pesticide intake was a significant indicator used to assess the safety of pesticides in food.…”

BACKGROUNDCitrus leaf miners are a common pest that harms citrus production and quality during citrus planting. During the citrus plant's growth phase, the bisultap formulation was frequently used to boost yield and produce fruit of high quality. Research on citrus's dietary risk assessment for bisultap residues, dissipation, and residues, however, is lacking.RESULTSLC‐MS/MS was used to develop an accurate and sensitive analytical method for derivatizing bisultap into nereistoxin in whole fruit, pulp, and peel. At various levels of addition, the mean recovery of bisultap ranged from 84.64 to 111.09% with a reasonable RSD (< 20%). The half‐lives in Guangxi and Guizhou were 3.96 and 6.03 d, respectively. After 14‐21 d of bisultap application, total residues (bisultap and its metabolite nereistoxin) in the whole fruit ranged between < 0.02‐0.228 mg kg‐1 in four experiment sites. And total residue (bisultap and nereistoxin, expressed by bisultap) in whole fruit was approximately 1.05‐7.23 times that of pulp. The washing process with tap water removed 85.71 to 98.78% of the bisultap residue in the whole fruit. Bisultap's risk assessment value in citrus was 0.16 to 1.28%.CONCLUSIONIn the whole citrus fruit, bisultap degrades rapidly. Bisultap residues primarily accumulate on citrus peels, so washing and peeling citrus may effectively remove bisultap residues. For various age groups, the chronic dietary risk of bisultap was acceptable.This article is protected by copyright. All rights reserved.
