“…Dioxane is considered nonbiodegradable and is difficult to remove from water. A recent study in Germany found it to be up to 62,260 ng/L in wastewater effluents, 2,200 ng/L in river water, and 600 ng/L in finished drinking water, which was above the precautionary guideline limit of 100 ng/L [93]. Interestingly, wastewater effluent levels from one plant were higher than wastewater influents due to dioxane impurities in the methanol used in the postanoxic denitrification process.…”

“…1,4-Dioxane is a widespread industrial contaminant in environmental waters (often exceeding water quality criteria and guidelines) and has been found in contaminated groundwater up to 2,800 μg/L [92], as well as in drinking water [13,93,94]. Dioxane is a high production chemical used as a solvent stabilizer in the manufacture and processing of paper, cotton, textile products, automotive coolants, cosmetics, and shampoos, as well as a stabilizer in 1,1,1-trichloroethane (TCA), a popular degreasing solvent.…”

The elimination of contaminants of emerging concern (CECs) during conventional wastewater treatment is not complete, and therefore, different amounts of these compounds are continuously released via wastewater effluents into the aquatic environment. This constitutes a major issue for water reuse, because these compounds can undergo transformation in the environment or during disinfection if reclaimed water is used for drinking water production. Different emerging contaminants, e.g., perfluorinated compounds, pharmaceuticals, antibacterials, plasticizers, and preservatives, and transformation products, which are in some cases more toxic than original compounds, have been occasionally found in finished drinking waters. The present chapter reviews the CECs detected in drinking water and the disinfection by-products generated by different CECs present in the aquatic environment. Moreover, the potential toxicologic effects that these pollutants and their transformation products pose for human health are also reviewed. Levels of these compounds in treated waters, and therefore exposure, could be reduced by the use of advanced removal technologies.

“…Therefore, 1,4-dioxane has been frequently detected in industrial effluents and sewage wastewater [1,3,4]. Moreover, due to the improper disposal of industrial wastes, accidental solvent spills, and inefficiency of conventional wastewater treatment (e.g., biological treatment and adsorption) for 1,4-dioxone removal [1,2,5,6], 1,4-dioxane has now been increasingly identified in surface water, groundwater, and even drinking water [1,7]. The ubiquitous presence of 1,4-dioxane in the aquatic environment has raised increasing concern because it can pose significant threat to the ecosystem and human health.…”

“…The ubiquitous presence of 1,4-dioxane in the aquatic environment has raised increasing concern because it can pose significant threat to the ecosystem and human health. For example, previous research has indicated that 1,4-dioxane can cause kidney failure and liver damage, and is also a possible human carcinogen [1,2,7]. To protect water resources, 1,4-dioxane wastewater has to be sufficiently treated before it can be discharged into the environment.…”

Efficient monitoring methods must be developed for 1,4‐dioxane, which is suspected to be carcinogenic to humans and is highly mobile in aquatic environments. In this regard, polar organic chemical integrative samplers (POCIS) have been utilized extensively as passive samplers for determining time‐weighted average concentrations of hydrophilic organic compounds. However, POCIS are difficult to apply to extremely hydrophilic known organic compounds with negative log octanol–water partition coefficient (Kow) values due to their limited kinetic sampling time. Using an activated carbon‐based sorbent with a high adsorption capacity and a bilayer of silicone and polyethersulfone membranes that inhibit mass transfer to the sorbent, we developed a POCIS device to measure 1,4‐dioxane (log Kow −0.27) in the present study. Permeation and field calibration tests demonstrated that the use of silicone membranes effectively reduces the water‐to‐sorbent mass transfer rate. The sampling rate and kinetic sampling period determined by field calibration tests were 1.4 ml day−1 and >14 days, respectively. Finally, the developed POCIS device was applied to a landfill treatment plant to determine the 1,4‐dioxane concentrations. Environ Toxicol Chem 2023;42:296–302. © 2022 SETAC
