Chemicals have improved our quality of life, but the resulting environmental pollution has potential to cause detrimental effects on humans and environment. People biota are chronically exposed thousands chemicals from various sources through multiple pathways. Environmental chemists toxicologists moved beyond detecting quantifying single characterizing complex mixtures in indoor outdoor environments biological matrices. We highlight analytical bioanalytical approaches isolating, characterizing, tracking groups concern Techniques that combine chemical analysis bioassays facilitate identification pose a combined risk.

Which Micropollutants in Water Environments Deserve More Attention Globally?

Environmental Science & Technology, Journal Year: 2021, Volume and Issue: 56(1), P. 13 - 29

Published: Dec. 21, 2021

Increasing chemical pollution of aquatic environments is a growing concern with global relevance. A large number organic chemicals are termed as "micropollutants" due to their low concentrations, and long-term exposure micropollutants may pose considerable risks organisms human health. In recent decades, numerous treatment methods technologies have been proposed remove in water, typically several were chosen target pollutants evaluate removal efficiencies. However, it often unclear whether toxicity occurrence levels frequencies enable them contribute significantly the overall environments. This review intends answer an important lingering question: Which or class deserve more attention globally should be removed higher priority? Different risk-based prioritization approaches used address this question. The risk quotient (RQ) method was found feasible approach prioritize scale its relatively simple assessment procedure extensive use. total 83 case studies using RQ past decade compiled, 473 compounds that selected by screening 3466 three broad classes (pharmaceuticals personal care products (PPCPs), pesticides, industrial chemicals) (RQ > 0.01). To determine importance, we propose surrogate, is, weighted average (WARQ). WARQ integrates intensity frequency achieve comprehensive priority determination. Through metadata analysis, recommend ranked list 53 micropollutants, including 36 PPCPs (e.g., sulfamethoxazole ibuprofen), seven pesticides heptachlor diazinon), 10 perfluorooctanesulfonic acid 4-nonylphenol) for management remediation efforts. One caveat importance does not consider transformation (including disinfection byproducts) new forms antibiotic resistance genes microplastics), directly applicable specific region country. Also, needs mentioning there might no best toward question, hopefully can act small step better answer.

Expanded Target-Chemical Analysis Reveals Extensive Mixed-Organic-Contaminant Exposure in U.S. Streams

Environmental Science & Technology, Journal Year: 2017, Volume and Issue: 51(9), P. 4792 - 4802

Published: April 12, 2017

Surface water from 38 streams nationwide was assessed using 14 target-organic methods (719 compounds). Designed-bioactive anthropogenic contaminants (biocides, pharmaceuticals) comprised 57% of 406 organics detected at least once. The 10 most-frequently anthropogenic-organics included eight pesticides (desulfinylfipronil, AMPA, chlorpyrifos, dieldrin, metolachlor, atrazine, CIAT, glyphosate) and two pharmaceuticals (caffeine, metformin) with detection frequencies ranging 66–84% all sites. Detected contaminant concentrations varied less than 1 ng L–1 to greater μg L–1, 77 278 having median 100 respectively. Cumulative detections ranged 4–161 compounds (median 70) 8.5–102 847 respectively, correlated significantly wastewater discharge, watershed development, toxic release inventory metrics. Log10 widely monitored HHCB, triclosan, carbamazepine explained 71–82% the variability in total number (linear regression; p-values: < 0.001–0.012), providing a statistical inference tool for unmonitored contaminants.

Multiple Roles of Dissolved Organic Matter in Advanced Oxidation Processes

Environmental Science & Technology, Journal Year: 2022, Volume and Issue: 56(16), P. 11111 - 11131

Published: July 7, 2022

Advanced oxidation processes (AOPs) can degrade a wide range of trace organic contaminants (TrOCs) to improve the quality potable water or discharged wastewater effluents. Their effectiveness is impacted, however, by dissolved matter (DOM) that ubiquitous in all sources. During application an AOP, DOM scavenge radicals and/or block light penetration, therefore impacting their toward contaminant transformation. The multiple ways which different types sources impact oxidative purification are critically reviewed. inhibit degradation TrOCs, but it also enhance formation and reactivity useful for elimination alter transformation pathways contaminants.
