Figure 7: Factorial analysis of the immune-related responses in mussels exposed to a physical-and chemical-treated effluent before and after ozone treatment. A factorial analysis was performed using the principal component procedure for the extraction of the factors. Abbreviations: CF: condition factor; ST: soft tissue weight ratio; GSI: gonado-somatic index; phag: phagocytic activity; phag effic: phagocytic efficiency or phagocytic activity/cell viability; Vtg: vitellogenin-like proteins; Adh: hemocyte adherence; Via: hemocyte viability, NOx: total nitrites and nitrates; COX: cyclooxygenase. The biomarkers that are clustered or close together indicate a significant and proportional response.
