Beta-lactamase-producing Enterobacterales bacteria cause severe hard-to-treat infections. Currently, they are spreading beyond hospitals and becoming a serious global health concern. This study investigated the prevalence and molecular characterization of extended-spectrum β-lactamase and AmpC-type β-lactamase-producing Enterobacterales (ESBL-PE, AmpC-PE) in wastewater from livestock and poultry slaughterhouses in Ardabil, Iran. A total of 80 Enterobacterales bacteria belonging to 9 species were identified. Among the isolates, Escherichia coli (n = 21/80; 26.2%) and Citrobacter spp. (n = 18/80; 22.5%) exhibited the highest frequency. Overall, 18.7% (n = 15/80) and 2.5% (n = 2/80) of Enterobacterales were found to be ESBL and AmpC producers, respectively. The most common ESBL producer isolates were E. coli (n = 9/21; 42.8%) and Klebsiella pneumoniae (n = 6/7; 85.7%). All AmpC-PE isolates belonged to E. coli strains (n = 2/21; 9.5%). As per the investigation, 80% (n = 12/15) of ESBL-PE and 100% (n = 2/2) of AmpC-PE isolates were recovered from poultry slaughterhouses wastewater. All ESBL-PE and AmpC-PE isolates were multidrug-resistant (MDR). In total, 93.3% (n = 14/15) of ESBL-PE isolates harbored the blaCTX-M gene, with the blaCTX-M-15 being the most common subgroup. The emergence of ESBL-PE and AmpC-PE in wastewater of food-producing animals allows for zoonotic transmission to humans through contaminated food products and contaminations of the environment.
产β-内酰胺酶的肠杆菌会导致严重的难治性感染。目前,它们正在向医院以外的地区扩散,成为全球严重的健康问题。本研究调查了伊朗阿尔达比勒市畜禽屠宰场废水中产广谱β-内酰胺酶和 AmpC 型β-内酰胺酶肠杆菌(ESBL-PE、AmpC-PE)的流行情况和分子特征。共鉴定出属于 9 个物种的 80 种肠杆菌。在分离的细菌中,大肠埃希菌(n = 21/80;26.2%)和柠檬酸杆菌属(n = 18/80;22.5%)出现的频率最高。总体而言,18.7%(n = 15/80)和 2.5%(n = 2/80)的肠杆菌属分别是 ESBL 和 AmpC 生产者。最常见的 ESBL 生产者分离物是大肠杆菌(n = 9/21;42.8%)和肺炎克雷伯菌(n = 6/7;85.7%)。所有 AmpC-PE 分离物均属于大肠杆菌菌株(n = 2/21;9.5%)。根据调查,80%(n = 12/15)的 ESBL-PE 和 100% (n = 2/2)的 AmpC-PE 分离物是从家禽屠宰场废水中回收的。所有 ESBL-PE 和 AmpC-PE 分离物均具有多重耐药性(MDR)。总共有 93.3% 的 ESBL-PE 分离物(n = 14/15)携带 blaCTX-M 基因,其中 blaCTX-M-15 是最常见的亚群。产粮动物废水中出现的ESBL-PE和AmpC-PE可通过污染的食品和环境传染给人类。

Onsite wastewater treatment systems (OWTSs) and private wells are commonly used in Eastern North Carolina, USA. Water from private wells is not required to be tested after the initial startup, and thus persons using these wells may experience negative health outcomes if their water is contaminated with waste-related pollutants including bacteria, nitrate or synthetic chemicals such as hexafluoropropylne oxide dimer acid and its ammonium salt (GenX). Water samples from 18 sites with OWTSs and groundwater wells were collected for nitrate, Escherichia coli (E. coli), total coliform, and GenX concentration analyses. Results showed that none of the 18 water supplies were positive for E. coli, nitrate concentrations were all below the maximum contaminant level of 10 mg L-1, and one well had 1 MPN 100 mL-1 of total coliform. However, GenX was detected in wastewater collected from all 18 septic tanks and 22% of the water supplies tested had concentrations that exceeded the health advisory levels for GenX. Water supplies with low concentrations of traditionally tested for pollutants (nitrate, E. coli) may still pose health risks due to elevated concentrations of emerging contaminants like GenX and thus more comprehensive and routine water testing is suggested for this and similar persistent compounds.

在美国北卡罗来纳州东部,现场废水处理系统 (OWTS) 和私人水井被普遍使用。私人水井的水在初次启动后不需要进行检测,因此,如果水受到与废物有关的污染物(包括细菌、硝酸盐或合成化学品,如六氟丙烯氧化物二聚酸及其铵盐(GenX))的污染,使用这些水井的人可能会受到不利的健康影响。从 18 个有 OWTS 和地下水井的地点采集了水样,进行硝酸盐、大肠杆菌(E. coli)、总大肠菌群和 GenX 浓度分析。结果表明,18 个供水点的大肠杆菌均未呈阳性,硝酸盐浓度均低于 10 毫克/升的最大污染物含量,其中一口井的总大肠菌群含量为 1 MPN 100 毫升/升。不过,从所有 18 个化粪池收集的废水中都检测到了 GenX,22% 的受测水源中的 GenX 浓度超过了健康警告水平。传统检测污染物(硝酸盐、大肠杆菌)浓度较低的水源仍可能因 GenX 等新出现的污染物浓度升高而对健康造成危害,因此建议对该污染物及类似的持久性化合物进行更全面的常规水检测。

Beachgoers' responses to beach health advisories. 海滩游客对海滩健康警告的反应。
IF 2.3 4区 环境科学与生态学 Q2 Medicine Pub Date : 2024-03-01 Epub Date: 2024-02-14 DOI: 10.2166/wh.2024.306

Drawing on responses from 238 beachgoers who have visited a Georgia (U.S. state) beach in the past three years, this study asks respondents about their knowledge of beach water quality monitoring, awareness of beach health advisories, perception of water quality, and expected responses upon learning of a beach's water pollution advisory. Binomial logistic regression finds that the only demographic predictor of respondents who would completely stop visiting a beach with an advisory is whether the respondent is a visitor or resident (year-round or part-time). Nearly 40% of visitors would not come to a beach with an advisory compared to 13.4% of residents. Most respondents report they would continue to visit a beach but would stay out of the water and stop harvesting seafood from the beach's waters. More than a third (36.1%), however, are unaware Georgia regularly monitors beach water for water quality, and 41.2% have never read a beach sign warning of contaminated water or seafood. Alarmingly, just over half view aesthetic factors such as no litter, no odor, and clear water as criteria for defining whether beach water is safe.

本研究通过 238 名在过去三年中去过佐治亚州(美国各州)海滩的游客的回答,询问了受访者对海滩水质监测的了解、对海滩健康警告的认识、对水质的感知以及在得知海滩水污染警告后的预期反应。二项式逻辑回归发现,受访者是游客还是居民(全年或非全日制)是唯一能预测受访者是否会完全停止游览发布警告的海滩的人口学因素。将近 40% 的游客不会前往发布警告的海滩,而居民的这一比例仅为 13.4%。大多数受访者表示,他们会继续前往海滩,但不会下水,也不会在海滩水域捕捞海鲜。然而,超过三分之一(36.1%)的受访者不知道佐治亚州会定期监测海滩水域的水质,41.2% 的受访者从未看过海滩上警告水或海鲜受污染的标语。令人担忧的是,仅有一半以上的人将无垃圾、无异味和水质清澈等美学因素视为界定海滩水质是否安全的标准。

This paper explores the socio-cultural and gender-based dynamics associated with place values, and their implication on women's access to water through case studies of upland and riverine communities in southern Nigeria. We used a range of fieldwork methods including public meetings, focus group discussions, in-depth interviews, keen observations, key informants and other secondary sources. Our findings show that drinking water sources are a part of the many forms of visible material structures that embody and generate automatic reproduction of gender-based beliefs, attitudes, feelings and practices. The outcome of such practices affects men and women differently in relation to access, workload and capacity for hygiene and other socio-economic practices. In discussing access to essential public goods, social and economic capacities take priority focus over the impact of ‘place values’ either as standalone or intersectional elements. Research should be expanded to incorporate these elements and their intersectional perspectives in shaping access to water.
本文通过对尼日利亚南部高地和河流沿岸社区的案例研究,探讨了与地方价值观相关的社会文化和性别动态,及其对妇女用水的影响。我们采用了一系列实地调查方法,包括公开会议、焦点小组讨论、深入访谈、敏锐观察、关键信息来源和其他二手资料来源。我们的研究结果表明,饮用水源是多种形式的可见物质结构的一部分,这些结构体现并自动复制了基于性别的信仰、态度、情感和习俗。这些做法的结果对男性和女性在卫生和其他社会经济做法的获取、工作量和能力方面产生了不同的影响。在讨论获得基本公共产品的问题时,社会和经济能力优先于 "地方价值观 "的影响,无论是作为独立因素还是交叉因素。应扩大研究范围,将这些因素及其交叉视角纳入影响水获取的因素中。

The present study found that ∼80 million people in India, ∼60 million people in Pakistan, ∼70 million people in Bangladesh, and ∼3 million people in Nepal are exposed to arsenic groundwater contamination above 10 μg/L, while Sri Lanka remains moderately affected. In the case of fluoride contamination, ∼120 million in India, >2 million in Pakistan, and ∼0.5 million in Sri Lanka are exposed to the risk of fluoride above 1.5 mg/L, while Bangladesh and Nepal are mildly affected. The hazard quotient (HQ) for arsenic varied from 0 to 822 in India, 0 to 33 in Pakistan, 0 to 1,051 in Bangladesh, 0 to 582 in Nepal, and 0 to 89 in Sri Lanka. The cancer risk of arsenic varied from 0 to 1.64 × 1-1 in India, 0 to 1.07 × 10-1 in Pakistan, 0 to 2.10 × 10-1 in Bangladesh, 0 to 1.16 × 10-1 in Nepal, and 0 to 1.78 × 10-2 in Sri Lanka. In the case of fluoride, the HQ ranged from 0 to 21 in India, 0 to 33 in Pakistan, 0 to 18 in Bangladesh, 0 to 10 in Nepal, and 0 to 10 in Sri Lanka. Arsenic and fluoride have adverse effects on animals, resulting in chemical poisoning and skeletal fluorosis. Adsorption and membrane filtration have demonstrated outstanding treatment outcomes.

本研究发现,印度有 8000 万人口、巴基斯坦有 6000 万人口、孟加拉国有 7000 万人口、尼泊尔有 300 万人口受到 10 μg/L 以上的砷地下水污染,而斯里兰卡仍然受到中度影响。在氟污染方面,印度有 1.2 亿人、巴基斯坦有 200 多万人、斯里兰卡有 50 多万人面临氟含量超过 1.5 毫克/升的风险,而孟加拉国和尼泊尔受影响程度较轻。砷的危害商数(HQ)在印度从 0 到 822 不等,在巴基斯坦从 0 到 33 不等,在孟加拉国从 0 到 1 051 不等,在尼泊尔从 0 到 582 不等,在斯里兰卡从 0 到 89 不等。砷的致癌风险在印度为 0 至 1.64 × 1-1,巴基斯坦为 0 至 1.07 × 10-1,孟加拉国为 0 至 2.10 × 10-1,尼泊尔为 0 至 1.16 × 10-1,斯里兰卡为 0 至 1.78 × 10-2。就氟而言,印度的 HQ 值为 0 至 21,巴基斯坦为 0 至 33,孟加拉国为 0 至 18,尼泊尔为 0 至 10,斯里兰卡为 0 至 10。砷和氟对动物有不利影响,会导致化学中毒和骨骼氟中毒。吸附法和膜过滤法的治疗效果显著。

The study objective was to evaluate human faecal contamination impacts in the Yal-ku lagoon in the Mexican Caribbean and to estimate adenovirus infection and illness risks associated with recreational exposure during water activities. A total of 20 water samples (10 from each site × two sites) (50 L) were collected monthly over a period of 12 months from two selected sampling sites in the swimming area of the Yal-ku lagoon. The occurrence of faecal-associated viruses was explored, and human adenovirus (HAdV) and pepper mild mottle virus (PMMoV) concentrations were quantified. A quantitative microbial risk assessment (QMRA) model was used to estimate exposure and subsequent adenovirus infection and illness risk for 1 h of swimming or snorkelling. Somatic and F + -specific coliphages occurred in 100% of the samples. Both HAdV and PMMoV were detected at a 60% frequency thereby indicating persistent faecal inputs. PMMoV concentrations (44-370 GC/L) were relatively lower than the concentrations of HAdV (64-1,000 GC/L). Estimated mean adenovirus risks were greater for snorkelling than for swimming by roughly one to two orders of magnitude and estimated mean illness risks for snorkelling were >32/1,000. Human faecal contamination is frequent in the Yal-ku lagoon, which is associated with human gastrointestinal illness.

研究的目的是评估墨西哥加勒比海亚尔库泻湖的人类粪便污染影响,并估计与水上活动中的娱乐接触相关的腺病毒感染和疾病风险。在为期 12 个月的时间里,每月从亚尔库泻湖游泳区的两个选定采样点收集共 20 份水样(每个采样点 10 份×两个采样点)(50 升)。研究了粪便相关病毒的发生情况,并量化了人类腺病毒(HAdV)和辣椒轻度斑驳病毒(PMMoV)的浓度。定量微生物风险评估(QMRA)模型用于估算游泳或浮潜 1 小时的接触情况以及随后的腺病毒感染和疾病风险。100%的样本中都出现了体细胞和 F + 特异性大肠杆菌。HAdV 和 PMMoV 的检测频率均为 60%,这表明粪便中持续存在腺病毒。PMMoV 的浓度(44-370 GC/L)相对低于 HAdV 的浓度(64-1,000 GC/L)。估计浮潜的平均腺病毒风险比游泳高出大约一到两个数量级,估计浮潜的平均疾病风险大于 32/1000。雅尔库泻湖经常受到人类粪便污染,这与人类肠胃疾病有关。

The implementation of precoagulation before the physical removal process is expected to achieve a high virus removal rate. However, viruses may form small flocs and subsequently escape into the effluent during physical removal processes. This study evaluated how viruses in the microflocs could be quantified using conventional virus quantification methods (plaque assay and quantitative polymerase chain reaction (qPCR)) to reveal the risk of underestimating virus concentration. In this study, the microfloc dissolution phenomenon in phosphate buffer solution was employed as a floc dissolution test. Viruses in microflocs formed under the experimental conditions, assuming that water treatments were quantified before and after floc dissolution. The findings revealed that virus concentrations increased by 1.0–3.9 log plaque-forming units/mL according to the plaque assay and by 1.7–4.0 log copies/mL according to the qPCR. This increase occurred after the dissolution of microflocs that were prepared in the humic acid test water. In the case of treated wastewater, virus concentrations increased in all samples according to the plaque assay and in seven of eight samples according to the qPCR. Our results indicate the necessity of careful consideration of virus quantification after precoagulation and physical removal systems.
在物理去除工艺之前进行预凝,可望达到较高的病毒去除率。然而,病毒可能会形成小絮体,随后在物理去除过程中逃逸到污水中。本研究评估了如何使用传统的病毒定量方法(斑块检测法和定量聚合酶链反应 (qPCR))对微絮凝体中的病毒进行定量,以揭示低估病毒浓度的风险。本研究采用微絮体在磷酸盐缓冲溶液中的溶解现象作为絮体溶解试验。假定在絮凝体溶解前后对水处理进行量化,在实验条件下形成的微絮凝体中的病毒。研究结果表明,根据斑块检测法,病毒浓度增加了 1.0-3.9 对数斑块形成单位/毫升,根据 qPCR 法,病毒浓度增加了 1.7-4.0 对数拷贝/毫升。这种增加发生在腐殖酸测试水中制备的微絮体溶解之后。在处理过的废水中,根据斑块检测法,所有样本中的病毒浓度都有所增加,根据 qPCR 法,8 个样本中有 7 个样本中的病毒浓度有所增加。我们的研究结果表明,有必要仔细考虑预凝和物理去除系统后的病毒定量问题。

Discharge of untreated wastewater into water bodies pollutes the receiving waters. This study assessed the impact of abattoir and Kampala designers' effluent discharge on the water quality of the Yemoja River in Abeokuta, Nigeria. Twenty-seven water samples collected at three points, covering 180 m length, for 6 months were assessed for physicochemical parameters and metals and compared with the World Health Organization and Standard Organization of Nigeria permissible standards. Most discharge point levels were found to be higher than their corresponding upstream and downstream values. Temperature, turbidity, magnesium, alkalinity, DO, TSS, phosphate, lead, BOD and potassium were found to be in excess of normal levels for river water as prescribed by the World Health Organization and Standard Organization of Nigeria while parameters like TDS, TS, calcium, chloride, nitrate, sulphate, iron and COD were lower than the standards. The total coliform values were higher than both national and international permissible limits, indicating contamination by human sewage or animal droppings. The water quality index indicated polluted water that is unfit for consumption. Findings from this research indicate that butchering and tie-and-dye activities have impacted river Yemoja water quality. Therefore, wastewater from the abattoir and textile industries be treated before discharge into water bodies.
向水体排放未经处理的废水会污染受纳水体。本研究评估了屠宰场和坎帕拉设计师排放的废水对尼日利亚阿贝奥库塔耶莫贾河水质的影响。研究人员在三个点收集了 27 份水样,长度为 180 米,历时 6 个月,评估了水样的理化参数和金属含量,并与世界卫生组织和尼日利亚标准组织的允许标准进行了比较。结果发现,大多数排放点的水平都高于其上游和下游的相应数值。发现温度、浊度、镁、碱度、溶解氧、总悬浮物、磷酸盐、铅、生化需氧量和钾超过了世界卫生组织和尼日利亚标准组织规定的河水正常水平,而总溶解氧、总悬浮物、钙、氯、硝酸盐、硫酸盐、铁和化学需氧量等参数则低于标准。总大肠菌群值高于国家和国际允许限值,表明受到人类污水或动物粪便的污染。水质指数表明,受污染的水不适合饮用。研究结果表明,屠宰和扎染活动影响了耶莫贾河的水质。因此,屠宰场和纺织业产生的废水应经过处理后再排入水体。

The present study explores the suitability of groundwater for drinking purpose and evaluates non-carcinogenic health risks for children, women, and men. For this purpose, 47 groundwater samples were collected and analyzed for physicochemical parameters, including nitrate concentration. The results revealed that nitrate concentration varied from 15 to 85 mg/L and that 48.93% of the groundwater samples exceeded the Bureau of Indian Standards’ limits of 45 mg/L. The spatial map of the pollution index of groundwater specifies that most of the study area lies in moderate to high pollution zones. Principal component analysis was also applied, and five principal components achieving eigenvalues more than 1 with a cumulative variance of 77.36% were found to be sufficient. The findings of non-carcinogenic risk rates range from 0.628 to 3.559 (average of 2.069) for children, 0.427 to 2.421 (average of 1.408) for women, and 0.362 to 2.049 (average of 1.191) for men, and approximately 80% of the population in the study region is exposed to high health risks. The health risk assessment specified that children in the study area are more susceptible than women and men. The findings of this study suggest that groundwater quality in the region has deteriorated, emphasizing the need for treatment before drinking.
