Figure 1. Spearman correlations between hepatic concentrations of THg, Se, MeHg, TOrgHg and age of Guiana dolphins.

Figure 1

The specimens are from Guanabara Bay, Rio de Janeiro State. Concentrations are in µg/g wet wt. and age in years. (A) Relationships between total mercury concentration (THg) and age. (B) Relationships between selenium concentration (Se) and age - data from fetus and neonates were excluded from the analysis. (C) Relationships between methylmercury concentration (MeHg) and age. (D) Relationships between total organic mercury (TOrgHg) and age.
