    Abstract Microplastic pollution in soil and its toxicological effects have attracted increasing attention from researchers, but the mechanisms of microplastics affecting crop growth and physiology remain unclear. A pot experiment was conducted to evaluate the impacts of various mass concentrations (0%, 0.2%, 5%, and 10%) of low-density polyethylene microplastics (LDPE MPs) on the germination rate, photosynthetic pigment content, biomass, antioxidant enzyme activity, soluble protein, and soluble sugar content of water spinach (

    Abstract SYP-3343, (E)-2-(2-((3-(4-chlorophenyl)-1-methyl-1H-pyrazole-5-yloxy)methyl)phenyl)-3-methoxyacrylate, is a newly developed strobilurin fungicide. However, the environmental behavior and fate of SYP-3343 in soil have not been well-documented. In this study, ¹⁴C-labeled SYP-3343 was employed to investigate the dynamic characteristics in three typical soils under aerobic conditions. Radioactivity analysis after high-performance liquid chromatography (HPLC) showed that SYP-3343 degraded rapidly in the coastal soil with a half-life of 43.8 days. After incubation of 100 days, its extractable residues were greater than 76.0% and bound residues were less than 12.4%, indicating that SYP-3343 was not easy to accumulate in soils. The mineralization to ¹⁴CO₂ reached 5.4% for acidic soil, 2.8% for neutral soil, and 1.7% for alkaline soil, suggesting that it was difficult to cleave the pyrazole ring completely. In addition, dynamic characteristics of SYP-3343 in sterile and non-sterile loamy soil showed that soil microbes affected SYP-3343 residue in soil and could accelerate the process of degradation and mineralization.
