Environmentally-related contaminants of high concern: Potential sources and analytical modalities for detection, quantification, and treatment

Environment International, Journal Year: 2018, Volume and Issue: 122, P. 52 - 66

Published: Nov. 28, 2018

In recent years, emerging contaminants (ECs) of high concern are broadly distributed throughout the environmental matrices because various industrial practices and anthropogenic inputs, i.e., human-made activities. With ever increasing scientific knowledge, technological advancement, socio-economic awareness, people now more about widespread distribution environmentally related ECs concern. As, possess serious ecological threats potential risks to human health aquatic life, even at minor concentrations. The controlled or uncontrolled discharge long-term persistence that includes micro-pollutants, endocrine disruptors (EDs), pesticides, pharmaceuticals, hormones, toxins, industrially-related synthetic dyes dyes-containing hazardous pollutants, etc. pose a significant challenge policy regulators, engineers, community. conventional treatment technologies proved ineffective for complete elimination removal an array in biological samples. order overcome aforementioned threats, tremendous research efforts have been made boost efficiency remediation techniques develop new modalities detect, quantify treat samples efficiently. boom biotechnology engineering offers opportunities advanced innovative field water treatment. This review discusses hazards associated with bodies, surface water, groundwater, wastewater streams. Life-cycle (micro)-pollutants suitable examples from sources viewpoints is also discussed. later part focuses on cost-effective (removal) approaches phase-changing these

Urban Stormwater: An Overlooked Pathway of Extensive Mixed Contaminants to Surface and Groundwaters in the United States

Environmental Science & Technology, Journal Year: 2019, Volume and Issue: 53(17), P. 10070 - 10081

Published: Aug. 21, 2019

Increasing global reliance on stormwater control measures to reduce discharge surface water, increase groundwater recharge, and minimize contaminant delivery receiving waterbodies necessitates improved understanding of stormwater–contaminant profiles. A multiagency study organic inorganic chemicals in urban from 50 runoff events at 21 sites across the United States demonstrated that transports substantial mixtures polycyclic aromatic hydrocarbons, bioactive contaminants (pesticides pharmaceuticals), other known or suspected pose environmental health concern. Numerous organic-chemical detections per site (median number detected = 73), individual concentrations exceeding 10 000 ng/L, cumulative up 263 ng/L suggested concern for potential effects during events. Organic concentrations, loads, yields were positively correlated with impervious surfaces highly developed catchments. Episodic storm-event loads comparable often exceeded those daily wastewater plant discharges. Inorganic chemical generally dilute concentration did not exceed chronic aquatic life criteria. Methylmercury was measured 90% samples ranged 0.05 1.0 ng/L.

Regulating water reuse for agricultural irrigation: risks related to organic micro-contaminants

Environmental Sciences Europe, Journal Year: 2020, Volume and Issue: 32(1)

Published: Jan. 18, 2020

Abstract In recent years, more and countries see irrigation using reclaimed water as an opportunity to secure enhance agricultural production. Despite the benefits of reuse, scientific community raised several concerns challenges for human health environment. This includes chemical risks. Effluents from urban wastewater treatment plants usually contain a wide range organic chemicals. Such chemicals remaining in after process may cause hazards health, contaminate surrounding soil resources, even compromise drinking sources. Once crops on irrigated sites are exposed chemicals, potential transport accumulation edible parts fruits vegetables need be controlled rule out their introduction into food chain. Finally, problems concerning release wastewater-borne antibiotics environment starting gain attention. For these reasons, should face stringent quality requirements order minimize Combinations measures reducing at source, technical natural processes especially remove with persistent, bioaccumulative toxic (PBT), or mobile (PMT) properties, good practices, supplementary preventive (e.g. knowledge transfer stakeholders involved) will necessary bring about ensure safe future. While internationally many regulations guidelines reuse have successfully been implemented, questions remain whether current regarding risks is sufficiently considered regulatory context. The new regulation attempted European Union, poses better take account.

Biofilm Thickness Influences Biodiversity in Nitrifying MBBRs—Implications on Micropollutant Removal

Environmental Science & Technology, Journal Year: 2016, Volume and Issue: 50(17), P. 9279 - 9288

Published: July 31, 2016

In biofilm systems for wastewater treatment (e.g., moving bed biofilms reactors-MBBRs) thickness is typically not under direct control. Nevertheless, likely to have a profound effect on the microbial diversity and activity, as result of diffusion limitation thus substrate penetration in biofilm. this study, we investigated impact nitrification removal more than 20 organic micropollutants laboratory-scale nitrifying MBBRs. We used novel carriers (Z-carriers, AnoxKaldnes) that allowed controlling at 50, 200, 300, 400, 500 μm. The community was assessed via 16S rRNA gene amplicon sequencing ammonia monooxygenase (amoA) abundance quantification through quantitative PCR (qPCR). Results from batch experiments analysis showed (i) thickest (500 μm) presented highest specific biotransformation rate constants (kbio, L g(-1) d(-1)) 14 out 22 micropollutants; (ii) positively associated with biodiversity, which suggested main factor observed enhancement kbio; (iii) thinnest (50 exhibited (gN d(-1) g(-1)), amoA kbio values some most recalcitrant (i.e., diclofenac targeted sulfonamides). Although thin favored activity micropollutants, based thicker should be considered enhance elimination broad spectrum micropollutants.
