Mussels were sampled during winter and spring to assess seasonal variability. NRRT values showed a significant reduction in both populations across both seasons, indicating compromised lysosomal integrity and exposure to environmental stressors. However, the wild mussels exhibited consistently lower NRRT values compared to the farmed individuals, suggesting a higher level of stress. The question of why is yet to be answered.enBlack SeapollutionmusselsLysosomal membrane stability assessment in wild and farmed mussels (Mytilus galloprovincialis Lamarck, 1819) as biomarkers for environmental stress: winter and spring resultsArticle
