“…Recent studies have gradually made it clear that a wide variety of pharmaceutical ingredients are present in the water environment Azuma et al, 2016;Tiedeken et al, 2017;Vasquez et al, 2014 . The concentration level of these pharmaceutical ingredients in the water environment ranges from ng/L to µg/L, which is lower than the concentration level mg/L that exerts pharmacological action in the human body.…”

Low-concentration Sorbic Acid Promotes the Induction of <i>Escherichia coli</i> into a Viable but Nonculturable State

et al. 2019

The effect of food preservatives and sanitizers at low concentrations on the induction of Escherichia coli into a viable but nonculturable VBNC state was investigated. When E. coli was incubated in physiological saline at 37 , the viable cell count measured by plate counting was approximately 3-logs lower than that measured by flow cytometry after 30 days. This difference, and morphological changes in cells, confirmed the transition of E. coli into a VBNC state. Adding 10 µg/l of sorbic acid significantly promoted the induction of E. coli into a VBNC state. This effect was not seen with benzoic acid or sodium hypochlorite at the same concentration. Resuscitation of E. coli VBNC cells was successful when they were grown in nutrient broth containing sodium pyruvate. These results suggest that the presence of low concentrations of food additives in a food manufacturing environment may act as potential triggers for bacterial VBNC induction.

“…(WFD, 2000). Previously, it wasn't pre-requisite to perform chemical analysis of PSs and CECs in the water bodies for environmental regulation (Tiedeken et al, 2017). However, increasing environmental concerns of these contaminants in the aquatic resources have greatly acknowledged their qualitative and quantitative analysis for the regulatory purpose to improve water quality and WFD has recommended continuous monitoring of these organic pollutants for all of the EU countries (WFD, 2015).…”

“…Recently, WFD recommended to establish water treatment strategies and monitor 54 PSs including 49 organic pollutants and 4 metals (WFD, 2015). For CECs, no definite EQS are existed, however, the previous studies have suggested a prioritization system based on two indicators, the extent of exceedance and the frequency of exceedance of predicted no effect concentrations (PNECs) (Ohe and Dulio, 2013;Tiedeken et al, 2017). Recently, WFD has listed 17 CECs to their Watch List (Decision 2015/495/EU), including five pharmaceuticals, such as erythromycin (ERY) and Diclofenac (DIC), etc.…”

Priority Substance (PSs) and Contaminant of Emerging Concerns (CECs) exhibited a wide range of environmental and public health concerns worldwide. This review summarized the documented studies related to the current surface water occurrence, spatial distribution, ecological risks and toxicity of selected PSs, such as polycyclic aromatic hydrocarbons (PAHs) and CECs, such as Di(2-Ethylhexyl) Phthalate (DEHP) and Pharmaceuticals and Personal Care Products (PPCPs). The spatial distribution analysis revealed alarming levels of PAHs in the surface waters of Asian counties, e.g., 84210 ng L −1 in Gomti River, India, 29325 ng L −1 in Daya Bay, China and 1287 ng L −1 in Chenab River, Pakistan. As for DEHP, the highest concentrations of 13050 µg L −1 in Liao River, China, and 2306 µg L −1 in Rivers of Eastern Cape, South Africa were reported. These environmental levels of PAHs and DEHP were many folds higher than the surface water permissible levels devised by WHO and USEPA. Contrarily, the emerging PPCPs were reported in relatively lower levels in the surface waters globally, compared to that of PAHs and DEHP. Consistent with the environmental levels, PAHs and DEHP revealed alarming ecological risks in the surface water sources, compared to that of PPCPs. Regarding to the sources of PSs and CECs, PAHs emissions were mostly linked to the incomplete combustion of petroleum products, DEHP contamination was associated to its applications in consumption and production of plastic appliances and PPCPs emissions were largely related to the domestic and industrial effluents. As for toxic endpoints of PAHs, DEHP and PPCPs, all of these were reported to cause DNA damage, genotoxicity, reproductive toxicity, developmental toxicity and immunotoxicity, as revealed in reviewed in vitro/vivo studies. In addition, the current review also highlighted the existing environmental regulations to control the emissions of these pollutants to the environmental matrices. Taken together, this review concluded that despite the existing environmental regulations, the current levels of organic pollutants are still on rising, especially in Asian countries. Therefore, the strict implementation of the existing regulations is highly necessary to control these pollutants to ensure public health and ecological integrity.

“…While an awareness regarding the occurrence and distribution of priority and emerging concern substances in EU catchments is developing [20,21], there is still a gap on the spreading of these contaminants in surface waters, including those restricted in the EU [21,22]. Considering that the majority of the chemicals are originated from urban and agricultural areas and enter in the aquatic environment mainly via urban runoff [23], and/or domestic and industrial wastewaters [21], a special focus should be addressed toward domestic and agricultural catchments [24,25].…”

Impact of sewage effluent discharges prediction using QUAL2Kw in a sensitive protected area: Portugal

et al. 2019

The quality of water, under the influence of the wastewater treatment plant's discharges, makes the simulation of the water parameters a key issue, broadly when considering intermittent rivers. In the case of study, the Pracana reservoir works as an example of the characterization, monitoring and control of the impact of several wastewater treatment plants' discharges, directly contributing to water quality. Proença-a-Nova's wastewater treatment plant contributes directly to the Pracana reservoir (Central Portugal), which is a protected field. Twelve georeferenced water samples were gathered, between the sewage discharge and downstream to the Pracana reservoir, at almost equal distances. Sampling campaigns were taken during three different periods: rainy winter (January), intermediate conditions (March) and dry season (June). The following chemical parameters were analyzed: biochemical oxygen demand (BOD 5 ), dissolved oxygen (DO), dry residue, P total , N total , pH, temperature and microbiological parameters. DO, BOD 5 and microbiological parameters served as indicators for environmental pollution evaluation. A coupled hydrodynamic and water dispersion model, QUAL2kw, was used for water's quality simulation. The results lead to conclude that the water quality is acceptable for multiple purposes, except for human consumption, mainly due to moderate-to-high values of BOD 5 .
