Predicting the magnitude of herbicide impacts on marine primary productivity remains challenging because extent worldwide pollution in coastal waters and concentration-response relationships phytoplankton communities to multiple herbicides are unclear. By analyzing spatiotemporal distribution at 661 bay gulf stations from 1990 2022, we determined median, third quartile maximum concentrations 12 triazine 0.18 nmol L

Ecotoxicity characterization of chemicals: Global recommendations and implementation in USEtox

Chemosphere, Год журнала: 2022, Номер 310, С. 136807 - 136807

Chemicals emitted to the environment affect ecosystem health from local global scale, and reducing chemical impacts has become an important element of European sustainability efforts. The present work advances ecotoxicity characterization chemicals in life cycle impact assessment by proposing recommendations resulting international expert workshops conducted under umbrella UNEP-SETAC Life Cycle Initiative GLAM project (Global guidance on environmental indicators). We include specific for broadening scope through introduce additional compartments beyond freshwater related indicators, as well adapting effect modelling approach better reflect environmentally relevant exposure levels including a larger extent chronic test data. As result, we (1) propose consistent mathematical framework calculating factors their underlying fate, parameters; (2) implement into USEtox scientific consensus model; (3) calculate reported inventory case study rice production consumption; (4) investigate influence data selection criteria indicator scores. Our results highlight need careful interpretation scores light robustness species sensitivity distributions. Next steps are apply recommended studies, adapt it soil, sediment marine environment. is applicable evaluating assessment, footprinting, substitution, risk screening, prioritization, comparison with targets.

Environmental Concentrations of Herbicide Prometryn Render Stress-Tolerant Corals Susceptible to Ocean Warming

Environmental Science & Technology, Год журнала: 2024, Номер 58(10), С. 4545 - 4557

Global warming has caused the degradation of coral reefs around world. While stress-tolerant corals have demonstrated ability to acclimatize ocean warming, it remains unclear whether they can sustain their thermal resilience when superimposed with other coastal environmental stressors. We report combined impacts a photosystem II (PSII) herbicide, prometryn, and on Galaxea fascicularis through physiological omics analyses. The results demonstrate that heat-stress-induced inhibition photosynthetic efficiency in G. is exacerbated presence prometryn. Transcriptomics metabolomics analyses indicate prometryn exposure may overwhelm repair mechanism corals, thereby compromising capacity for acclimation. Moreover, might amplify adverse effects heat stress key energy nutrient metabolism pathways induce stronger response oxidative corals. findings at environmentally relevant concentrations would render more susceptible exacerbate breakdown Symbiodiniaceae symbiosis. present study provides valuable insights into necessity prioritizing PSII herbicide pollution reduction reef protection efforts while mitigating climate change.

Environmental risk assessments strategies that account for the complexity of exposures are needed in order to evaluate toxic pressure emerging chemicals, which also provide suggestions mitigation and management, if necessary. Currently, most studies on co-occurrence environmental impacts chemicals concern (CECs) conducted countries Global North, leaving massive knowledge gaps South. In this study, we implement a multi-scenario assessment strategy improve both exposure hazard components chemical process. Our incorporates systematic consideration weighting CECs were not detected, as well an evaluation uncertainties associated with Quantitative Structure-Activity Relationships (QSARs) predictions chronic ecotoxicity. Furthermore, present novel approach identifying mixture drivers. To expand our beyond well-studied aquatic ecosystems, applied River Aconcagua basin Central Chile. The analysis revealed concentrations exceeded acceptable thresholds selected organism groups vulnerable taxonomic groups. Streams flowing through agricultural areas sites near river mouth exhibited highest risks. Notably, eight drivers among 153 co-occurring accounted 66–92 % observed risks basin. Six them pesticides pharmaceuticals, classes known their high biological activity specific target organisms.

Ecotoxicological mixture risk assessment of 35 pharmaceuticals in wastewater effluents following post-treatment with ozone and/or granulated activated carbon

The Science of The Total Environment, Год журнала: 2023, Номер 906, С. 167440 - 167440

Reducing the risk posed by mixtures of pharmaceuticals is a goal current initiatives such as European Green Deal to reduce anthropological environmental impacts. Wastewater effluent typically contains large numbers active pharmaceutical ingredients (APIs). For some APIs, existing technology conventional activated sludge (CAS) wastewater treatment plants (WWTPs) have removal rates below 20 %, thus WWTP discharges are adding toxic burden receiving waters. We present an assessment 35 APIs in samples from 82 Northern WWTPs using concentration addition model, and identify respective risk-driving APIs. This then compared corresponding mixture Danish Hillerød subjected post-treatment with varying specific ozone doses (0.15-1.05 mgO3/mgDOC) and/or granulated carbon (GAC). All exceeded thresholds at least factor 30, median RQSUM 92.9, highlighting need for substantial dilution recipient Antibiotics, analgesics anti-depressants were among top drivers 99 % average attributable azithromycin, diclofenac, venlafaxine, clarithromycin mycophenolic acid. Effluent was reduced ozonation concentration-dependent manner, decreasing threshold levels 0.83 following 0.65 mgO3/mg DOC. Fresh GAC also effective reducing both alone treatment, 0.04 0.07 respectively. To our knowledge, this first study comparing "conventional" processes additional joint risks demonstrate technologies, efficacy aquatic environment acceptable limits.
