Fig. 6From: Multilevel responses of adult zebrafish to crude and chemically dispersed oil exposureMicronuclei in peripheral erythrocytes of adult male zebrafish after 3 and 21 d of exposure to WAF dilutions of crude oil (5% and 25% WAFOIL) and chemically dispersed crude oil (5% WAFOIL+D). Results are presented as mean ± standard deviation for n = 7–11. Letters indicate statistically significance between treatments within the same sampling point and asterisks indicate statistically significance between sampling timepoints (p < 0.05)Back to article page
