“…Pesticide residual risk level was ranked by adapting the ranking matrix developed by the Veterinary Residues Committee of UK (VRC, 2020; Yao, Yan, Chen, et al., 2020). The prioritization score ( PS ) of each positive pesticide was calculated by Equation (1):

P S = (A + B) \times (C + D + E) \times F

where, A is the pesticide toxicity score, B is the score of pesticide toxic potency, C is the score of tea diet proportion of in total dietary intake, D is the score of the frequency of a particular pesticide usage during tea planting, E is the score of the evidence of high exposure populations, and F is the score of residue level.…”

“…Demographic characters like gender and age may affect the dietary exposure risk due to various people's consumption habits and corresponding data. Recent studies have shown that the dietary exposure risk of pesticide residues through some food consumption for young children was relatively higher than that of the general population (Claeys et al., 2011; Szpyrka et al., 2015; Yao, Yan, Chen, et al., 2020). Moreover, since more than one pesticide residue may be contained in a food, people are exposed daily to multiple pesticides through diet.…”

White tea has been of increasing public interest worldwide owing to its health benefits. Based on 2 years of surveillance, the long-term and cumulative chronic exposure risks of pesticide residues through white tea drinking were assessed for different subpopulations in Fujian, China. Twenty-five different pesticides were found, and 74.8% of samples contained at least one pesticide residue.The most frequently detected pesticide was bifenthrin with detection rates of 61.6%. Risk assessment was performed using both the deterministic approach and semiprobabilistic model under the best-case and the worst-case scenarios.The results demonstrated that the dietary risks were extremely low for six different subpopulations in which the risks for adults over the age of 41 were relatively higher. The risk ranking scheme indicated that isocarbophos and triazophos were considered to be of medium risk. The different use suggestions for the 25 positive pesticides are proposed to further minimize the exposure risk to consumer health.Practical Application: Tea is the second most popular nonalcoholic beverage throughout the world. Pesticides are used to improve the yield of tea. Pesticide residues in tea could be one of the exposure pathways for consumers. Monitoring residual levels and assessing the health risk assessment in tea are thus in an urge.

The "white tea" was named for its silky white fuzz covering the immature leaves and buds (Damiani et al., 2014). Depending on the tenderness of its fresh tea shoots, white tea is classified into three main groups. These are Baihaoyinzhen (Silver Needle, BMYZ, bud only), Bai MuDan (White Peony, BMD, a bud with one or two leaves), and Shou Mei (Long Life Eyebrow, SM, two or more leaves) (Tan et al., 2017; Yue et al., 2019). Unlike oolong tea or black tea, white tea is prepared with only a few steps, including prolonged withering and drying without fermentation (Dai et al., 2017;Luo et al., 2020). Hence, white tea is reported to have a higher concentration of total polyphenols, some alcohol volatiles (e.g., hexanal, benzaldehyde, and benzene acetaldehyde), catechins, and gallic acid than those in other teas (Hilal & Engelhardt, 2007;Unachukwu et al., 2010;L. Wang et al., 2010;K. Wang et al., 2011). Due to a wide range of health benefits (e.g., antioxidant, antimicrobial, and anticancer effects) and its ability to alleviate inflammation, elastic skin, and rheumatoid arthritis, white tea has attracted increasing attention and

“…In 91 snow fungus samples collected from Fujian Province, pyridaben was one of the highest frequently detected pesticide, with a detection rate of 9.9% and residues in the range of 0.011–0.046 mg/kg ( Yao et al, 2020 ). In 151 honeysuckle samples collected from different planting bases in China, pyridaben was detected in 42.19% samples in 2017 and 45.98% samples in 2018, with residues in the range of 0.001–0.075 mg/kg and 0.001–0.080 mg/kg, respectively.…”

Pyridaben is an acaricide widely used around the world to control phytophagous mites, white flies, aphids, and thrips. It is highly toxic to nontarget organisms such as predatory mites, bees, and fishes. Therefore, the occurrence and removal of pyridaben in food and the environment are worthy of concern. This mini-review focuses on pyridaben residue levels in crops, aquatic systems, and soils, as well as the green synthesis and removal of pyridaben. During the period of 2010–2022, pyridaben was reported in monitoring studies on fruits, vegetables, herbs, bee products, aquatic systems, and soils. Vegetable and agricultural soil samples exhibited the highest detection rates and residue levels. One-pot synthesis offers a green chemistry and sustainable alternative for the synthesis of pyridaben. Among traditional home treatments, peeling is the most effective way to remove pyridaben from crops. Magnetic solid-phase extraction technology has emerged as a powerful tool for the adsorption and separation of pyridaben. Photocatalytic methods using TiO2 as a catalyst were developed as advanced oxidation processes for the degradation of pyridaben in aqueous solutions. Current gaps in pyridaben removal were proposed to provide future development directions for minimizing the exposure risk of pyridaben residues to human and nontarget organisms.

The presence of pesticide residues in Dendrobium officinale (D. officinale), a commonly used herbal medicine, has attracted much attention in recent years. Therefore, this study presents the levels of 141 pesticide residues in forty D. officinale samples, which were measured by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). And we used a deterministic estimate model to assess chronic and acute dietary exposure risk, as well as the cumulative risks for adults, children, and specific groups of consumers. Furthermore, the residual risk of individual pesticides was sorted by adapting the matrix-ranking scheme. In 92.5% of the samples, 43 pesticides were detected, of which difenoconazole had the highest detection frequency. Multiple residues were detected in 85.0% of the samples, and one sample contained even up to 17 pesticides. The chronic hazard quotient (HQc) and the acute hazard quotient (HQa) were far below 100%, and both cumulative chronic and acute hazard indices (HI) did not exceed 100%. The risk scoring scheme showed that four pesticides were considered to pose a comparatively potential high risk, including difenoconazole, carbofuran, fipronil, and emamectin benzoate. The results indicated that the occurrence of pesticide residues in D. officinale could not pose a serious health problem to the public.
