Histological, Genotoxic, and Biochemical Effects on Cnesterodon decemmaculatus (Jenyns 1842) (Cyprinodontiformes, Poeciliidae): Early Response Bioassays to Assess the Impact of Receiving Waters

Figure 6

Biomarkers and morphological parameters of oxidative stress in Cnesterodon decemmaculatus exposed to different treatments for 96 hs. Treatments: NC (negative control, MHW); RR (surface water of the Reconquista River); RR+Cd (surface water of the Reconquista River with 2 mg Cd/L); Cd (2 mg Cd/L). Values are expressed as mean ± SEM. Treatments not sharing a common letter are statistically different from each other (ANOVA followed by Tuckey test, p < 0.05). Number of individuals analyzed in each treatment: 16-22.
