Tebuconazole (TBZ) is a widely used systemic fungicide (Youness et al. 2018). Its structure is (RS)-1-p-chlorophenyl-4,4-dimethyl-3-(1H-1,2,4-triazol-1-ylmethyl)-pentan-3-ol (Fig. 2). The fungicidal activity of TBZ is based on its capability to target specifically the 14a-demethylase (CYP51), which is a regulatory enzyme of the ergosterol biosynthetic pathway. Ergosterol plays an essential role in fungal membrane formation, altering its structure and functions such as permeability and fluidity (Desmyttere et al. 2019).

Tebuconazole is a highly effective triazole fungicide to control a range of plant pathogens in fruits, vegetables, and crops [19]. It is relatively persistent in the environment with a half-life of tens of days to approximately 600 days and shows low to moderate mobility [20]. This pesticide can enter the aquatic ecosystem through runoff and endanger marine organisms. The concentration of tebuconazole ranged from 9.1 ug/L to 200 ug/L in surface water and the runoff events nearby farms [21]. Manjarres-López et al. [22] tested pesticide residues in groundwater of La Rioja Oriential vineyards (southern Spain) in different seasons, and the results showed that 30 pesticide residues were detected, among them, tebuconazole and other two pesticides were the most frequently detected in water samples. Due to the high residue, stability, and toxicity of tebuconazole, this pesticide is abundant in the aquatic system. Thus, the environmental behaviours of tebuconazole in water may be changed by MPs, which were also existed in the aquatic environment.

Fungicides constitute an important group of pesticides. According to Eurostat 2018, the sales volume of fungicides in the EU is approximately 45% [3]. Fungicides, like other pesticides, are transported directly and indirectly to aquatic areas after being used. Studies on the effects of fungicides on non-target organisms have been more limited than with other pesticides [4]. The fungicide tebuconazole (TEB) (2-[2-(4-chlorophenyl)ethyl]-3,3-dimethyl-1-(1H-1,2,4-triazol-1-yl)butan-2-ol) is a teriozole group fungicide that is used extensively for combating fungal diseases. TEB exhibit antifungal activity by inhibiting ergosterol, a component of the fungal membrane. Fish are one of the most important groups among non-target animals. TEB causes oxidative stress and damage in fish species by causing an increase in lipid peroxidation and reactive oxygen species [5,6], abnormal development and apoptosis in larvae and embryos [7,8], endocrine disrupting effects [9,10], abnormalities in osmoregulation [11] hepatotoxicity [12], behavioural disorders [13], and hematological injuries [14], alterations of gill apparatus [15].
