The control of waterborne diseases through water disinfection is a significant advancement in public health. However, the process generates by-products (DBPs), including trihalomethanes (THMs), which are considered to influence occurrence cancer. This analysis aims quantitatively evaluate relationship between blood concentrations THMs and Additionally, chloroform concentration cancer analyzed separately. Following PRISMA guidelines, we conducted thorough search PubMed, Web Science, CNKI databases. Statistical was performed using Review Manager 5.4 software. After screening, seven studies meeting evaluation criteria were included. A total 1027 samples from patients with 7351 group collected. average experimental 46.71 pg/mL, while it 36.406 pg/mL group. difference two groups statistically (SMD = −0.36, 95% CI: −0.45 −0.27, p < 0.00001). due limited research data on cancer, conclusions drawn exhibit high heterogeneity. discussed carcinogenic mechanisms THMs, involve multiple biological pathways such as oxidative stress, DNA adduct formation, endocrine disruption, variations accumulation target sites potentially leading different types, for evidence currently lacking. In future, further epidemiological animal model should be obtain more accurate conclusions.

Dissolved organic matter (DOM) is the primary precursor of disinfection products (DBPs) during chlorination. However, compositional characteristics DOM transformation chlorination process in different source waters and its relationship to cytotoxicity remain understudied. Here, we used high-resolution mass spectrometry evaluate chlorination-induced molecular-level changes derived from surface water sources. We correlated components with profiles selected DBPs using new alternative methods predictive toxicological assessments. Our findings indicate a selective natural tendency for lignin protein conversion manual process. The reactivity bioactive compounds decreased order > tannin or ConAC. mainly attributed lignin- protein-like within CHO CHNO groups. Additionally, mitochondrial damage highly sensitive indicator DOM-induced cytotoxicity. toxicity revealed 37 common toxicity-driving characterized by low mass, medium H/C ratio, O/C reduction state, hydrophobicity. highlight need exploit health effects provide substantial experimental evidence necessity remove potential toxicants.

Approaches focused on improving animal health are essential strategies to increase the quality and productivity of livestock sector. Bovine mastitis is a prevalent disease in dairy farming worldwide. There various ways prevent infections mammary inflammation cows, such as using sanitizers or disinfectants before after milking clean cow's udder surface reduce contamination. Chlorine-based commonly used, some cases, antibiotics used mastitis. This review aimed analyze scientific articles that plants sanitizer for last 5 years. were few records experiments with disinfecting cows' udders; total 10 12 plant species mentioned, including twice Piper betle Acacia nilotica. Among classes metabolites indicated active terpenoids, flavonoids, tannins. Studies indicate extracts exhibit antimicrobial properties. Plant-based promote sustainable environmentally friendly sanitation production sector, these products biodegradable renewable.

The prevalence of disinfection by-products in drinking water supplies is a global concern due to their carcinogenicity. However, the monitoring DBPs such as trihalomethanes (THMs) and haloacetic acids (HAAs) non-existent many developing Asian, South American, African countries. formation THMs during arises from reaction between disinfectant natural organic matter water, particularly, dissolved carbon (DOC). This hastened by increases temperature, high levels doses or residual, elevated pH, long contact times, DOC concentrations. inclusion granular activated adsorption process treatment most effective method for removal main precursor (DOC) treated water. Barekese WTP, which disinfects with chlorine, has no removal, over 80% pipe-borne city Kumasi Ghana, was assessed THM potential (THMFP). A predictive model used determine concentration final THMFP at WTP ranged 22.42 38.94 µg/L, below 100 µg/L threshold set WHO. lifetime average daily were 3.9494 × 10−4 µg/Kg/d 3.9294 male female consumers, respectively. integrative cancer risks associated consumption 1.817 10−5 1.808 males females, risk posed acceptably low. direct measurement required corroborate these findings verify consumers inform policies, regulations, public health interventions, investment.

All water destined for human consumption must be subjected to disinfection processes via chlorination with the aim of eliminating risk transmission waterborne diseases. However, treatment using this method leads formation trihalomethanes (THMs), which are toxic compounds that may ingested, inhaled, or absorbed by skin, increasing carcinogenic and mutagenic processes. High trihalomethane concentrations in directly related physicochemical properties, such as temperature, pH, hardness, potentially metal concentrations. In work, characterization was performed quality assessed regard presence 17 samples collected from points before after storage reservoirs. Atomic absorption spectroscopy determine metals measurement properties demonstrated all results were accordance standards established Brazilian legislation. Gas chromatography–mass spectrometry used levels (trichloromethane, bromodichloromethane, chlorodibromomethane, bromoform), also limits Hierarchical clustering on principal components confirmed changes depending location. This work constitutes a paradigm future studies monitoring organic avoid health problems humans animals.
