“…New wastewater treatment technologies for emerging pollutants including ozonation, membrane filtering, or activated carbon, are in the early phases of development. Questions regarding toxicity levels of transformation products, costs, or energy efficiency have yet to be resolved (Altmann et al 2012). An environmental quality norms approach regulates compound by compound.…”

With an increasing awareness of newly detected but unregulated pollutants in waterbodies, the question arises as to how these emerging issues concerning water quality should be politically addressed. Environmental economists have advocated market-based instruments because of their effectiveness, cost-efficiency, and flexibility. However, lessons from past experiences where market forces were used to solve public problems indicate that issues related to administrative complexities, legitimacy, or uncertainty can arise. Turning the academic debate into an empirical one, this chapter takes an actor perspective and assesses the potential for introducing market-based instruments through the example of Switzerland, a forerunner in developing water policy to control emerging pollutants. Findings show that Swiss policy actors have a preference for command-and-control or voluntary instruments ahead of marketbased approaches for reducing emerging pollutants in water.

“…The biological effects of wastewater on algae have been evaluated in some locations overseas, which have reported that some wastewater has had biologically harmful effects on algae, and that wastewater treatment decreased these effects [1][2][3][4]. In Japan, the Ministry of the Environment has considered the introduction of the Whole Effluent Toxicity test [5] (named J-WET in this paper) for the management of chemicals in wastewater.…”

In Japan, there is little knowledge about the reduction in biological effects of wastewater on aquatic organisms by wastewater treatment, and a toxicant(s) contained in wastewater. The purpose of this study was to examine seasonal variation in the biological effect of the influent and final effluent obtained from a wastewater treatment plant, and to characterize the toxicant(s) in the wastewater using an algal growth test. The influents in every season tested had a growth-inhibiting effect on Pseudokirchneriella subcapitata. The final effluent in winter also had the same effect, but the final effluents in other seasons did not. The growth-inhibiting effects of the effluent in winter might be due to a reduction in the biological treatment ability caused by a decrease in water temperature, which may have led to the presence of residue of some toxicants in the effluent. A Toxicity Identification Evaluation (TIE) test suggested that the potential toxicants in the influent were non-polar organic toxicants and surfactants, among others, and that the toxicants in the final effluent were oxidants and pH-dependent toxicants. These potential toxicants appeared to be similar to chemicals suggested by the Pollutant Release and Transfer Register (PRTR) information, implying that this information is useful for identifying toxicants.

“…Public awareness and pressure have influenced both industries and governments to take actions to control the situation but some of the organic compounds, termed micropollutants, are present at such low concentration (pg L À1 to ng L À1 ) in water that most established treatment processes seldom lead to their elimination [5]. Some of these micropollutants are either known or suspected to be endocrine disrupting chemicals (EDCs) and have the potential to modulate, mimic or disrupt the endocrine system of living organisms in receiving ecosystems [6]. To date, an effective and sustainable global strategy against this insidious contamination of the aquatic environment barely exists.…”
