Water was one of the main vehicles of transmission, in addition to foods that showed classic behavior in terms of microbiological transmission. Weaknesses were observed in the records that limit the carrying out of more specific analyses due to the large number of inconsistent, ignored, or inconclusive cases, which, in some parameters, exceeded 50% of notifications.

The overall carcinogenic and noncarcinogenic risks resulting from exposure to DBPs through multiple pathways were 1.15 × 10-5 and 2.59 × 10-2, respectively. For different exposure routes, oral exposure to DBPs contributed the most to carcinogenic risk (1.13 × 10-5) and noncarcinogenic risk (2.52 × 10-2). The subgroup analysis revealed that the younger the child, the greater health risk they faced. The carcinogenic and noncarcinogenic risks for children aged 1-2 years were 2.56 × 10-5 and 5.75 × 10-2, respectively.

Studies consistently reported elevated illness risks (particularly gastrointestinal) among bathers compared with non-bathers. However, no FIOs or pathogens were associated consistently with any health outcomes. While enterococci most frequently correlated with a variety of illnesses, the relatively even split of positive and negative associations suggests an overall lack of association. Consequently, applying FIO guidelines derived from epidemiological studies with point sources of sewage could result in type I and type II errors. Overall, results suggest that the sources and drivers of health risks are site-specific. Tools including sanitary surveys, microbial source tracking, epidemiology and quantitative microbial risk assessment provide avenues for characterising site-specific health risks, for those who can afford them. Meanwhile, characterising the site-specific sources/drivers of contamination seems pragmatic as the limited evidence so far suggests that FIO monitoring may not be sufficient to protect health in these waters.","PeriodicalId":17436,"journal":{"name":"Journal of water and health","volume":"23 5","pages":"563-586"},"PeriodicalIF":2.5,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144191937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sulpiride had the highest average load, followed by venlafaxine, clozapine, quetiapine, and diazepam. The higher load of diazepam in suburban WWTPs than in urban WWTPs reflects the large numbers of older people living in suburban areas in most of China. The lower loads of most target compounds in suburban WWTPs than in urban WWTPs indicate a greater likelihood of mental disorders in urban people than in suburban people.

Twenty-four water samples from six tobacco fields (TFs) and six non-tobacco fields (NTFs), collected before cropping season and after cropping season, were analyzed for major physico-chemical properties and HMs. The results suggest that TF improves sodium and alkalinity hazards but worsens nutrient and HM pollution (Pb: 0.119 mg/L, Cd: 0.021 mg/L, Ni: 0.242 mg/L), and threatens salinity, permeability, osmotic potential (OPπ), dry residue (RS), and miscellaneous hazards. Conversely, NTF has minimal impact, except for nutrient and miscellaneous hazards. WQI shifts from good to very poor, primarily driven by turbidity, PO4-P, K+, and NO3-N. Similarly, WHI declines from excellent to very poor in TF and from good to poor in NTF. HM pollution index has risen slightly above irrigation safety limits, mainly due to Cd, Ni, and Pb, resulting in a slightly elevated ER.

AMR profiling revealed resistance to beta-lactam antibiotics such as amoxicillin and penicillin, with multidrug resistance observed in E. coli, Staphylococcus spp., and non-lactose fermenting bacteria. However, susceptibility to colistin and levofloxacin was noted in some isolates.
