Figure 3From: Mercury immune toxicity in harbour seals: links to in vitro toxicity Percentage of surviving cells estimated by Trypan blue coloration after 72 h of MeHg exposure. * p < 0.05; **, p < 0.01 relative to control PBMCs 100%. 5 wells per condition for both species. Humans: n = 8 for 0.1 μM and 1 μM; n = 3 for other concentrations. Harbour seals: n = 5 for 1 μM and n = 2 for other concentration.Back to article page
