Oxidation processes and me

Water Research, Год журнала: 2024, Номер 253, С. 121148 - 121148

Опубликована: Янв. 16, 2024

This publication summarizes my journey in the field of chemical oxidation processes for water treatment over last 30+ years. Initially, efficiency application oxidants micropollutant abatement was assessed by target compounds only. is controlled reaction kinetics and therefore, second-order rate constant these reactions are pre-requisite to assess feasibility such processes. Due tremendous efforts this area, we currently have a good experimental data base constants many oxidants, including radicals. Based on this, predictions can be made without with Quantitative Structure Activity Relationships Hammet/Taft or energies highest occupied molecular orbitals from quantum computations. Chemical has economically feasible extent transformation micropollutants often limited mineralization cannot achieved under realistic conditions. The formation products oxidant inherent following questions evolved years: Are formed biologically less active than compounds? Is there new toxicity associated products? more biodegradable corresponding In addition positive effects quality related micropollutants, react mainly matrix components as dissolved organic matter (DOM), bromide iodide. As fact, fraction consumed DOM typically > 99%, which makes inherently inefficient. consequences loss capacity inorganic disinfection byproducts also involving iodide, oxidized reactive bromine iodine their ensuing DOM. Overall, it turned out three decades, that complex understand manage. However, research led understanding underlying allow widespread optimized practice drinking water, municipal industrial wastewater reuse systems.

Mammalian Cell Genotoxicity of Potable Reuse and Conventional Drinking Waters

Environmental Science & Technology, Год журнала: 2024, Номер 58(20), С. 8654 - 8664

Опубликована: Май 6, 2024

Potable reuse water is increasingly part of the supply portfolio for municipalities facing shortages, and toxicity assays can be useful evaluating potable quality. We examined Chinese hamster ovary cell acute direct genotoxicity waters contributed by disinfection byproducts (DBPs) anthropogenic contaminants used local conventional drinking as benchmarks Our results showed that treatment trains based on reverse osmosis (RO) were more effective than RO-free reducing influent wastewaters. RO-treated less genotoxic tap derived from surface water, whereas not treated RO similarly when frequent replacement granular activated carbon limited contaminant breakthrough. The nonvolatile, uncharacterized DBPs accounted ≥73% total genotoxicity. (semi)volatile current research interest 2–27% toward genotoxicity, with unregulated being important drivers regulated DBPs. underscore need to look beyond known, importance determining whole assessing quality disinfected waters.

Bridging knowledge gaps in human chemical exposure via drinking water with non-target screening

Critical Reviews in Environmental Science and Technology, Год журнала: 2024, Номер unknown, С. 1 - 25

Опубликована: Сен. 1, 2024

Fundamental knowledge gaps still exist in the exposome, especially regarding analytical space coverage, mapping and prioritization of a very large number diverse chemical structures. This review focuses on contributions suspect non-target screening (NTS) to contaminants characterization toxicity assessment drinking water. A comprehensive publications from 2013-2024 revealed only 172 substances identified with certainty using NTS 17 countries. The approaches, their complementarity, effectiveness use compound identification frameworks are discussed. 'intelligent' tools (including machine learning) aid substance identification, is emerging. Strategies for integration epidemiology also considered, including re-use existing data. holds great potential exposure water its contribution exposome.
