Stool samples from infected patients were used as endogenous viral material to more accurately mirror real-world decay processes compared to more traditionally used lab-propagated spike-ins. As such, this study includes data on early decay stages of endogenous viral targets in wastewaters that are typically overlooked when performing decay studies on wastewaters harvested from wastewater treatment plants that contain already-degraded endogenous material. The two distinct sewer transport conditions of dynamic suspended sewer transport and bed and near-bed sewer transport were simulated in this study at temperatures of 4 °C, 12 °C and 20 °C to elucidate decay under these two dominant transport conditions within wastewater infrastructure. The dynamic suspended sewer transport was simulated over 35 h, representing typical flow conditions, whereas bed and near-bed transport extended to 60 days to reflect the prolonged settling of solids in sewer systems during reduced flow periods. In dynamic suspended sewer transport, no decay was observed for SARS-CoV-2, PMMoV, or total RNA over the 35-h period, and temperature ranging from 4 °C to 20 °C had no noticeable effect. Conversely, experiments simulating bed and near-bed transport conditions revealed significant decreases in SARS-CoV-2 and total RNA concentrations by day 2, and PMMoV concentrations by day 3. Only PMMoV exhibited a clear trend of increasing decay constant with higher temperatures, suggesting that while temperature influences decay dynamics, its impact may be less significant than previously assumed, particularly for endogenous RNA that is bound to dissolved organic matter in wastewater. First order decay models were inadequate for accurately fitting decay curves of SARS-CoV-2, PMMoV, and total RNA in bed and near-bed transport conditions. F-tests confirmed the superior fit of the two-phase decay model compared to first order decay models across temperatures of 4 °C–20 °C. Finally, and most importantly, total RNA normalization emerged as an appropriate approach for correcting the time decay of SARS-CoV-2 exposed to bed and near-bed transport conditions. These findings highlight the importance of considering decay from the point of entry in the sewers, sewer transport conditions, and normalization strategies when assessing and modelling the impact of viral decay rates in wastewater systems. This study also emphasizes the need for ongoing research into the diverse and multifaceted factors that influence these decay rates, which is crucial for accurate public health monitoring and response strategies.</div></div>","PeriodicalId":13994,"journal":{"name":"International journal of hygiene and environmental health","volume":"263 ","pages":"Article 114477"},"PeriodicalIF":4.5,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142396299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, long-term survival associated with submicron particulate matter (PM&lt;sub&gt;1&lt;/sub&gt;, PM with aerodynamic diameter ≤1 μm) exposure remained largely unstudied, particularly in highly exposed populations.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;We performed a population-based investigation involving 86844 adults aged 16+ years from 3 national dynamic cohorts spanning from 2005 to 2018. Residential annual exposure to PM&lt;sub&gt;1&lt;/sub&gt; and PM&lt;sub&gt;2.5&lt;/sub&gt; was assigned for each follow-up year using satellite-derived spatiotemporal estimates at a 1-km&lt;sup&gt;2&lt;/sup&gt; resolution. The concentration of PM&lt;sub&gt;1-2.5&lt;/sub&gt; (PM with aerodynamic diameter between 1 and 2.5 μm) was calculated by subtracting PM&lt;sub&gt;1&lt;/sub&gt; from PM&lt;sub&gt;2.5&lt;/sub&gt;. Time-independent Cox proportional hazards regression models were applied to assess the associations of all-cause mortality with long-term exposure to size-specific particles. To investigate the effect of PM&lt;sub&gt;1&lt;/sub&gt; on PM&lt;sub&gt;2.5&lt;/sub&gt;-mortality associations, we categorized participants into low, medium, and high groups based on PM&lt;sub&gt;1&lt;/sub&gt;/PM&lt;sub&gt;2.5&lt;/sub&gt; ratio and examined the risk of PM&lt;sub&gt;2.5&lt;/sub&gt;-associated mortality in each stratum.

Participants were exposed to an average annual concentration of 31.8 μg/m³ (range: 7.6–66.8 μg/m³) for PM&lt;sub&gt;1&lt;/sub&gt;, 56.3 μg/m³ (range: 19.8–127.2 μg/m³) for PM&lt;sub&gt;2.5&lt;/sub&gt;, and 24.5 μg/m³ (range: 7.3–60.3 μg/m³) for PM&lt;sub&gt;1-2.5&lt;/sub&gt;. PM&lt;sub&gt;1&lt;/sub&gt;, PM&lt;sub&gt;2.5&lt;/sub&gt;, and PM&lt;sub&gt;1-2.5&lt;/sub&gt; were consistently associated with elevated mortality risks, with a hazard ratio (HR) of 1.029 (95% confidence interval [CI]: 1.013–1.046), 1.014 (95% CI: 1.005–1.023), and 1.019 (95% CI: 1.001–1.038) for each 10-μg/m&lt;sup&gt;3&lt;/sup&gt; increase in exposure, respectively. Compared with low (HR = 0.986, 95% CI: 0.967–1.004) and medium (HR = 1.015, 95% CI: 1.002–1.029) PM&lt;sub&gt;1&lt;/sub&gt;/PM&lt;sub&gt;2.5&lt;/sub&gt; ratio groups, PM&lt;sub&gt;2.5&lt;/sub&gt;-related risk of mortality was more pronounced in high PM&lt;sub&gt;1&lt;/sub&gt;/PM&lt;sub&gt;2.5&lt;/sub&gt; ratio stratum (HR = 1.041, 95% CI: 1.019–1.064).

However, minimizing the risks, particularly those associated with emerging contaminants that may induce resistance among pathogens in wastewater, is crucial. This study assessed the occurrence of antibiotic-resistant bacteria in untreated wastewater used for agricultural purposes and evaluated the quantifiable health risks associated with this practice in Tamale, Ghana. The resistance of some Enterobacteriaceae, such as <em>E. coli, Klebsiella, and Salmonella-Shigella,</em> to four commonly used antibiotics in Ghana was assessed using a conventional microbiological culture approach and the Kirby Bauer disk diffusion method. A Quantitative Microbial Risk Assessment (QMRA) was performed to estimate the health risks associated with two distinct scenarios of wastewater reuse: (1) accidental ingestion of contaminated wastewater and soil, and (2) consumption of vegetables irrigated with wastewater. This approach applied a Monte Carlo simulation based on 10,000 interactions and identified <em>E. coli</em> O157:H7 as the reference pathogen. Among Enterobacteriaceae, <em>Klebsiella pneumoniae, Salmonella-Shigella</em> and <em>E. coli</em> were isolated, in concentrations exceeding the limit recommended by the World Health Organization (10<sup>3</sup> CFU/100 ml). All the isolated bacteria were resistant to metronidazole (5 μg). Thirty-three per cent of <em>Klebsiella pneumoniae</em> isolates were intermediate/moderately susceptible, and all other bacteria were resistant to amoxicillin (30 μg). All <em>Klebsiella pneumoniae</em> and the majority of <em>Salmonella-Shigella</em> (69.8 %) isolates were resistant to trimethoprim-sulfamethoxazole (25 μg) and tetracycline (30 μg). When assessing health risks, the mean annual probability of infection associated with consuming vegetables irrigated with wastewater varied between 5.14 × 10<sup>−2</sup> and 9.79 × 10<sup>−1</sup> per person per year. Conversely, for the accidental ingestion scenario, the probability was 1.00 per person per year. In these scenarios, the probability of illness ranged from 1.29 × 10<sup>−2</sup> to 2.4 × 10<sup>−1</sup> and 2.5 × 10<sup>−1</sup> per person per year. The health risks posed by these findings surpass the maximum threshold prescribed by the World Health Organization, thereby emphasizing the need for prompt mitigation strategies.</div></div>","PeriodicalId":13994,"journal":{"name":"International journal of hygiene and environmental health","volume":"263 ","pages":"Article 114478"},"PeriodicalIF":4.5,"publicationDate":"2024-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142383066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
