A Machine Learning Approach for Predicting Plant Uptake and Translocation of Per- and Polyfluoroalkyl Substances (PFAS) from Hydroponics

ACS ES&T Engineering, Journal Year: 2024, Volume and Issue: 4(8), P. 1884 - 1890

Published: June 4, 2024

Plant uptake and accumulation of per- polyfluoroalkyl substances (PFAS), represented by the root concentration factor (RCF), shoot (SCF), translocation (TF), were predicted using machine learning (ML) models from experimental data with 19 PFAS compounds nine plant species. Unsupervised principal component analysis (PCA) was first used to classify input data, then supervised ML models, including multiple linear regression model (MLR), artificial neural network (ANN), random forest (RF), support vector (SVM) algorithms, applied for predicting chosen output parameters. RF displayed highest prediction accuracy among tested models. Feature importance performed showed that molecular weight, exposure time, species are most important parameters RCF, SCF, TF in hydroponic systems. further estimate two prevalent compounds, perfluorooctanoic acid (PFOA) perfluorooctanesulfonic (PFOS), their common alternatives results revealed replacing have either comparable or higher roots shoots. Our demonstrated approach could generate critical insight into shed light on potential food safety concerns replacements.

Exploring per- and polyfluoroalkyl substance distribution in Arctic wastewater treatment lagoons and natural wetlands: First record in Nunavik, Canada

Chemosphere, Journal Year: 2025, Volume and Issue: 374, P. 144186 - 144186

Published: Feb. 16, 2025

Per- and polyfluoroalkyl substances (PFAS), as emerging bioaccumulative contaminants, are widely present in water wastewater systems. Municipal effluents serve pathways for PFAS to enter aquatic environments. This study monitors the treatment lagoons, nearby wetlands bay a Canadian Arctic community. Eight out of 40 targeted were detected samples collected from raw wastewater, natural wetlands, Ungava bay. The total concentrations ranges 45.9-56.1 ng/L 36.6-70.8 measured at 7.3 most prevalent frequently 6:2 FTS, PFHxA, PFNA. At all sites, short-chain surpassed long-chain PFAS. Short-chain peaked 267.01 (79.74%), while totaled 67.83 (20.26%). estimated yearly mass flow rate into environment through lagoon effluent was 2.33 g/year. conducted environmental risk assessment both lagoons three downstream suggests that risks associated with under posed minimal ecological risk, though long-term evaluation is needed. In conclusion, findings this research provide further information on pollution regions may, such, guide development comprehensive regulations safeguard human health environment, thereby mitigating potential future risks.

Storm Daniel Extreme Flood Event in Thessaly, Greece: Assessing the Pollution Status of the Impacted Coastal Marine Areas through Extended Screening of Emerging Contaminants Using LC-TIMS-HRMS

Environmental Science & Technology Letters, Journal Year: 2025, Volume and Issue: 12(4), P. 432 - 439

Published: March 4, 2025

In this study, we investigate the pollution status in impacted seawaters and sediments of coastal areas region Thessaly, central Greece, following Storm Daniel extreme flood event September 2023, a phenomenon classified as deadliest Mediterranean tropical-like cyclone recorded history one costliest cyclones beyond North Atlantic. For this, an ultra high-performance liquid-chromatography-based wide-scope target screening more than 2300 LC-amenable emerging contaminants (ECs) was carried out utilizing technique TIMS-QTOF-MS. Our results highlight fact that floodwater runoff resulted extensive transportation terrestrial derived material from major transport plant protection products, pharmaceuticals, including even illicit drugs, surfactants, industrial chemicals, per- polyfluorinated alkyl compounds (PFAS) at sea, result overflowing local wastewater treatment plants destruction agricultural, industrial, port facilities. Overall, alteration classification determined ECs most importantly study area, with potential implications for their environmental quality status.
