Emerging and Persistent Contaminants in a Remote Coastal Stream System: Five Priority Compounds in Southeast Asia

Sustainability, Journal Year: 2025, Volume and Issue: 17(2), P. 581 - 581

Published: Jan. 14, 2025

This study is a preliminary assessment of the emerging and persistent contaminants (EPCs) in ecologically sensitive Kamphuan Stream Southern Thailand. The analysis 15 compounds revealed that EPC concentrations below main community were significantly elevated during rainy season, with highest levels found for sucralose (9070 ng/L), metformin (6250 fexofenadine (5110 gabapentin (3060 ng/L). These spatiotemporal patterns highlight episodic nature contamination driven by urban stormwater runoff, where rainfall events create temporary pathways transport EPCs to streams draining into coastal ecosystems. Maximum three pharmaceuticals (diclofenac, gemfibrozil, ibuprofen), as well sucralose, caffeine, fenobucarb, exceeded general predicted no-effect (PNECs) marine or fresh waters; however, these not persistent. Limited sampling across campaigns constrained ability fully characterize dynamics this issue through statistical inference. Furthermore, risk assessments absence locally derived PNECs tropical ecosystems organisms, along limited standardization PNEC determination methodologies, making definitive conclusions challenging. A comparative five priority metformin, naproxen, fluoxetine) against existing data from East Southeast Asia underscores need further research evaluate ecological risks posed diverse rivers streams. Future studies should focus on greatest importance, investigate their transformation products, identify sources pathways, assess environmental aquatic
