This study evaluated how different levels of sediment metal contamination (ranging from below to above toxicity thresholds) and exposure durations (3–14 days) influence metal bioaccumulation and biomarker responses in fish under estuarine conditions. Using an integrated biomarker approach, the relationships among environmental contamination, metal accumulation, and fish health were examined to improve biomonitoring strategies....
