“…In the last couple of decades the advances in water quality analytical techniques has led to an increased focus on water micropollutants and emerging contaminants such as pharmaceuticals [1][2][3][4][5]. The presence of therapeutic drugs in the aquatic environment is becoming widespread [5][6][7][8], mainly because actual wastewater treatment plants (WWTP) fail on a quantitative removal of many of these pollutants [9][10][11].…”

“…For instance, even though phosphorus fertilizer production from easily accessible phosphate rock could be depleted in 50-100 years and cause global food security issues [7,8], expensive treatment technologies are used to remove phosphorus as waste from wastewater to reduce eutrophication in receiving water [9][10][11][12][13]. Emerging chemical and biological contaminants from wastewater and eroded sediments penetrate into the source water, making the treatment of drinking water more technically and financially challenging [14][15][16]. These vicious cycles worsen with the growth of cities, the concentration of agricultural practices, and intensifying material flows.…”

Urban water systems are an example of complex, dynamic human-environment coupled systems which exhibit emergent behaviors that transcend individual scientific disciplines. While previous siloed approaches to water services (i.e., water resources, drinking water, wastewater, and stormwater) have led to great improvements in public health protection, sustainable solutions for a growing global population facing increased resource constraints demand a paradigm shift based on holistic management to maximize the use and recovery of water, energy, nutrients, and materials. The objective of this review paper is to highlight the issues in traditional water systems including water demand and use, centralized configuration, sewer collection systems, characteristics of mixed wastewater, and to explore alternative solutions such as decentralized water systems, fit for purpose and water reuse, OPEN ACCESSSustainability 2015, 7 12072 natural/green infrastructure, vacuum sewer collection systems, and nutrient/energy recovery. This review also emphasizes a system thinking approach for evaluating alternatives that should include sustainability indicators and metrics such as emergy to assess global system efficiency. An example paradigm shift design for urban water system is presented, not as the recommended solution for all environments, but to emphasize the framework of system-level analysis and the need to visualize water services as an organic whole. When water systems are designed to maximize the resources and optimum efficiency, they are more prevailing and sustainable than siloed management because a system is more than the sum of its parts.

“…Sewage is normally composed of many types of pollutants. Raw sewage may contain high levels of pollutants like nutrients, inorganic chemicals, organic micropollutants, microorganisms and microbial products like endotoxins [4,6,12]. In the present study 21 (4.29%) of the 489 specimens showed cell toxicity and could not be processed further.…”

Comparison of ELISA and dual stage real time RT-PCR to differentiate Sabin like and non-Sabin like poliovirus isolates

et al. 2017

Environmental surveillance of polioviruses has been used as an important tool in monitoring circulation of wild polioviruses and/or Vaccine derived polioviruses in sewage samples. It is important to distinguish Sabin like isolates from non-Sabin like; ELISA & dual stage real time RT-PCR have been used for the same. Current study was carried out on sewage isolates to compare ELISA & RT-PCR with sequencing to distinguish Sabin like from non-Sabin like. Out of 468 sewage specimens, 91 (19.44%) were non-polio enteroviruses positive and 377 (80.56%) were polio positive by virus isolation method. A total of 488 polio virus isolates were detected by L20B and RD route which were further subjected to ELISA and RT-PCR. The results were compared with sequencing. On comparison, the specificity of ELISA was only 66.67% in spite of very low sensitivity (3.43%). The sensitivity of RT-PCR was 97.71% which makes it a good primary screening test for detection of non-Sabin like viruses. However, the specificity was only 33.33%. RT-PCR appears to be a sensitive tool for detecting non-Sabin like viruses however; the isolates which are non-Sabin like by RT-PCR may not necessarily be mutated viruses. ELISA cannot be used for differentiation of Sabin likes from non-Sabin likes due to low sensitivity.
