This gap deserves further concern given the tendency of pyridaben to remain in soil. 4-Chloro-2-(1,1-dimethylethyl)-5-[[[4-(1,1-dimethylethyl)phenyl]methyl]thio]-3(2H)-pyridazinone-d13; 2-tert-Butyl-5-(4-tert-Butylbenzylthio)-4-chloropyridazin-3(2H)-one-d13; BAS 300-d13; Damanlin-d13; GWN 1715-d13; NC 129-d13; NCI 129-d13; Nexter-d13; Pyramite-d13; Sanmite-d13; Chloroform (Slightly), DMSO (Slightly), Ethyl Acetate (Slightly), Methanol (Slig.

A low dose of H2O2 can also improve the photocatalytic rate by removing surface-trapped electrons and increasing the efficiency of hole utilization on TiO2 particles, as well as providing sufficient oxygen for photocatalytic degradation.

As a nonsystematic broad-spectrum acaricide, pyridaben is mainly applied in orchards, crop fields (in particular vegetables), tea plantations, and gardens to control phytophagous mites, white flies, aphids, and thrips (Igarashi and Sakamoto, 1994; Rand and Clark, 2000; Kim et al., 2015). Considering the risks of pyridaben to humans and nontarget organisms, its occurrence and removal are worthy of concern. 105, 104222. doi:10.1016/j.jfca.2021.104222, Rand, G. M., and Clark, J. R.

Pyridaben (2-tert-butyl-5-(4-tert-butylbenzylthio)-4-chloropyridazin-3(2H)-one) is an acaricide containing pyridazinone moiety. TP1TP15 were identified as photolytic products using gas chromatography tandem mass spectrometry (Figure 1B) (Zhu et al., 2004; Zhu et al., 2005).

(2017), pyridaben is stable under the treatment of pasteurization, baking/brewing/boiling, and sterilization. At the beginning of autumn, pyridaben is often used to prevent European red mite in apple orchards in China. Stud. Compared with washing, blanching improved the removal of pyridaben by 27.6%29.5%. FIGURE 1. Therefore, effective vegetables processing methods need to be developed. B., Kong, Z. Q., et al. Pyridaben exhibited high toxicity to bees (LD50 = 0.535g/bee for acute oral toxicity and LD50 = 0.024g/bee for acute contact toxicity) (European Food Safety Authority, 2010; Bahreini et al., 2020). Direct photolysis dominated the photodegradation of pyridaben at 300 < 360nm, while photocatalysis degradation by TiO2 was dominant at 360nm. (2016).

Various methods are employed to remove pyridaben for minimizing the risk of human and ecosystems exposure to it. In turn, its penetration to ground water and surface water is limited. Updating the principles and methods of risk assessment: MRLs for pesticides and veterinary drugs.

It has been demonstrated that no correlation exists between water solubility of pesticides and pesticide removal by washing (Christensen et al., 2003; Chung, 2018). Gomez, C., Bandez, M.

In another study of five local fruit cultivars in Shanghai, 1 out of 40 peach samples was positive for pyridaben, with a residue value of 7.8g/kg (Zhang et al., 2021). The degradation rate of pyridaben increased with the increase of catalyst TiO2, nevertheless, an overdose of TiO2 would retard the photocatalytic reaction (Zhu et al., 2005).
