“…Pollutants include heavy metals can cause an imbalance between the free radical species production and reduction in fish (Livingstone, 2003;Sevcikova et al, 2011;Kamollerd et al, 2019). The free radicals can attack lipid, protein and DNA molecules to induce oxidative stress products as well as cause DNA damage (Castano and Becerril, 2004;Vilela et al, 2018;Kamollerd et al, 2019).…”

Keywords:River Nile, Rosetta Branch, water quality, heavy metals, Orechromus niloticus, Inter-simple sequence repeats (ISSR)The present study aims to evaluate the water quality of two locations in Rosetta Branch of River Nile and its histopathological and genetic adverse effects on Nile tilapia (Oreochromis niloticus). Water and fish samples were collected from up and downstream of El-Rahawy Drain discharge point (location I and II, respectively) during the summer and winter seasons. The water quality, liver histopathology and DNA alteration of fish was examined. ISSR-PCR technique was used to assess the genetic variation of fish samples from these locations. The water quality parameters ( BOD, COD,……)were increased at location II compared with location I in addition to depletion in dissolved oxygen. Moreover, the fish samples collected from location II showed severe histological and molecular alterations than those collected from location I. It is recommended that the government must increase the awareness of people around the River Nile, and improve the environmental management to reduce the risks of polluted water and consuming the fish exposed to this water on human health.

With a growing population and expansion, societies worldwide brave lack water for drinking supply. Undeveloped sources of water should be specified to diminish such issues. Direct potable reuse is a supply-side procedure that can enhance the sustainability and reliability of water supplies via recuperating potable water from wastewater. This work assesses the perspective of upgrading the wastewater treatment plants to obtain potable water. Treating wastewater at the highest level of purity to guarantee the drinking water supply is the best approach to avoid the pollution expansion from wastewater even if it is partially treated to minimize its toxic impacts and provide water for irrigation and industrial use purposes. Treating wastewater at present in the actual wastewater treatment plants should be urgently upgraded to provide potable water through adding processes steps such as nanofiltration, reverse osmosis, and adsorption on activated carbon. Evidently, there is an additional cost for these sophisticated techniques to pay for the better future of the humankind. Finally, from the authors' point of view, treating wastewater must be continuously improved by using more and more developed techniques and consuming directly treated wastewater as potable water must be only considered as the final issue in the case of hard shortage situations for security reasons.

“…Considering the growing human population [1] and ever-expanding industries, humankind is confronted with an increasing quantity of pollutants in sewage and the landscape [2]. A wide variety of substances is discharged into nature [3,4], but in particular only one type of them aroused special attention in the past, the endocrine disruptive chemicals (EDCs) [5]. They are known for their ability to interfere with the hormone system of vertebrates, and influence it in a way restricting these species in their fertility and ability to mate with conspecifics [6][7][8].…”

Development of A Novel High Throughput Photo-catalyst Screening Procedure: UV-A Degradation of 17α-Ethinylestradiol with Doped TiO2-Based Photo-catalysts

The rising pollution of surface water by endocrine disruptive chemicals (EDCS) could lead to the persistent harm of aquatic wildlife. Addressing this concern, advanced waste water treatment techniques should be established in addition to the present sewage treatment. Therefore, the promising advanced oxidation process of photocatalysis is discussed. With the aim of establishing a novel high throughput screening approach for photocatalysts, a workflow resting upon the use of a self-constructed 60-fold parallel stirring UV-A LED photoreactor, followed by parallel sample extraction by SPE and sequential automated analysis by GC-MS, was developed, and is presented in this article. With the described system, TiO 2 -based photocatalysts, doped with different amounts of zinc, and synthesised by a sol-gel-route, were tested regarding their activity in the photocatalytic degradation of the synthetic estrogen 17α-ethinylestradiol. Thereby, the functional behavior of the photoreactor system and its applicability in a high throughput process could be evaluated. As a result of the catalyst screening, TiO 2 catalysts with low amounts of zinc were found with a significantly higher activity, compared to undoped TiO 2 . In conclusion, the presented system provides an easily accessible high throughput method for a variety of photocatalytic experiments.Materials 2020, 13, 1365 2 of 17 active [11]. To maintain the conditions of fresh water, municipal sewage treatment plants are introduced to the hydrological cycle, but it has been reported in literature that it is not possible to sustainably remove a plurality of micropollutants, and therefore EDC, from our wastewaters with the widespread activated sludge process [12][13][14][15]. In addition to this common type of sewage treatment, advanced oxidation processes (AOPs) like ozonation [16][17][18][19][20][21], or physical removal techniques like nanofiltration [22][23][24][25] and adsorption to charcoal [26][27][28][29][30], have been discussed lately. While these additional treatments deliver satisfying results regarding the reduction of micropollutants, they are inseparably linked to certain disadvantages, such as the generation of hazardous products and the disposal of adsorbents. Another, and presumably the most promising treatment procedure, is the photocatalysis [31][32][33][34], which is another variant of an AOP. Concerning the semiconductor materials utilised in this process, titanium dioxide (TiO 2 ) is the most established and examined one [35][36][37][38][39][40][41][42][43]. Apart from the fact that it is already known that estrogens could be degraded satisfactorily with the help of photocatalysis making use of TiO 2 , only few information has been gathered respecting reaction kinetics, matrix effects, reaction products, doped TiO 2 catalysts, and other semiconductors completely differing in their composition from TiO 2 for the deployment in photocatalytic reactions. For targeting these research subjects in depth, it is essential to implement procedures which enable a con...
