Seasonally different toxicity drivers in a river system revealed by insights from POCIS, bioassays, and suspect screening

Key Points

• Toxicity levels are driven by seasonal factors, impacting river ecosystem health.
• Results indicate significant variability in toxicity with varying seasonal conditions, suggesting adaptation is required.
• Assessment using POCIS, bioassays, and suspect screening reveals key contributors to river toxicity.
• Highlights the importance of continuous monitoring to understand ecological impacts and improve water quality management.
