In this study, a rainfall simulation device was employed to investigate the response mechanism of soil leachate and disinfection by-products formation potential (DBPsFP) to extreme precipitation events. The results revealed that the aromaticity of dissolved organic matter (DOM) and the concentration of hydrophobic DOM containing aromatic carbon groups in leachate decreased with rising temperature. The humification degree of DOM decreased at 25 °C (99 mm/h), while the humification degree and protein-like level of DOM increased under high temperatures droughts (45 °C and 65 °C).

The relationships between water quality parameters, fluorescence parameters, and the formation levels of THMs and HAcAms were analyzed. The fractions contributing most to the acute toxicity were identified.

- - Trichloroacetamide (TCAcAm) is a harmful nitrogenous disinfection by-product found in drinking water, and the study investigates ways to effectively eliminate it using advanced reduction processes (ARP), particularly through vacuum ultraviolet (VUV) methods.
- - The VUV/sulfite process outperformed other methods, achieving an 85.6% removal rate for TCAcAm, primarily due to the generation of highly reactive species, notably electrons (e), which were critical for the compound's degradation.
- - Factors like pH and the presence of substances like dissolved oxygen and bicarbonate influenced the decomposition efficiency; optimal TCAcAm removal occurred at a pH above 8.3, while
