Concentration of pollutants and their derivated effects are one of the most important elements in the evaluation of aquatic environment through biomonitoring programs. Samples of mussel gill homogenates are important to evaluate biomarkers of water pollution, such as total oxidant status (TOS) and total antioxidant capacity (TAC)
Evaluated assays showed adequate precision when gills homogenates were used. with intra- and interassay CVs lower than 15%, and recovery percent between 80% and 120%, which are the agreed limits for good method functionality (Table 1).
Table 1. The homogenites showed to be adequate for TAC and TOS measurement in mussel gills.
