“…Although research has shown that emerging DBPs such as HALs, HANs, and HAMs pose a higher carcinogenic health effect on humans compared to THMs and HAAs, 54 the carcinogenic risk is positively correlated with the concentrations of DBPs when the concentrations are low in drinking water. 15 Among THMs, the CRs to humans through drinking water ingestion are ranked from high to low as TCM, BDCM, DBCM, and TBM, consistent with the studies conducted by Minashree, Zhen, and others. 15,55 Except for TBM, the other three THMs present a moderate carcinogenic risk to health effects on humans, while the CRs of TBM for all three age groups are less than 10 −6 , possibly due to their deficient concentration.…”

Disinfection by-products (DBPs) in drinking water pose a threat to human health. This study, for the first time, investigated the distribution of 22 DBPs in the drinking water of 32 cities along the Yangtze River Basin and Yellow River Basin and assessed their health effects on the Chinese population. The concentrations of total DBPs in drinking water from the Yangtze River Basin (11.0−122.6 μg/L) are essentially consistent with those in the Yellow River Basin (12.0−122.2 μg/L). The levels of trihalomethanes (THMs) and haloacetic acids (HAAs) in most cities were within limits set by the "Standards for Drinking Water Quality" (GB 5749−2022). Additionally, haloacetaldehydes (HALs) and haloacetonitriles (HANs) were found to be the primary driving factors for cytotoxicity and genotoxicity. The Yangtze River Basin and Yellow River Basin exhibited medium to high carcinogenic risks from DBPs for different population groups. However, no potential non-carcinogenic risks from DBPs to human health (HQs < 1) have been observed. In conclusion, controlling DBPs in drinking water, especially unregulated DBPs, is necessary to reduce their harm to human health.

“…The research shows that the combination of online UV-Vis spectroscopy and chemometrics can simulate the operator's decisionmaking in determining coagulant dosage. Pang et al [14] established a correlation model based on the relationship between disinfection by-products (DBPs) and physical and chemical parameters to predict and analyze the toxicity of DBPs. Volf et al [15] established four time models to predict the water quality index (WQI) of drinking WTP.…”

As an important part of the water purification process, coagulant dosage will directly affect the water quality, the cost of water purification and profit of the drinking WTP. Coagulant dosage is a complex physical and chemical reaction process, which has the characteristics of time-varying, nonlinear and large time delay [1]. In the traditional drinking WTP, the human experiences and the jar tests are mainly used to determine the coagulant dosage [2]. The human experience method is that the operator adds the coagulant according to the turbidity of the raw water and his own experience. The jar test method is to simulate the coagulation dosing environment according to the raw water quality, so as to determine the coagulant dosage amount.
