Lead-induced oxidative stress in isolated fathead minnow gills. Whole gill preparations from naïve adult fish were incubated with lead nitrate for 60 min according to published methods (17). n = 4 fish/lead concentration. Average GSH/GSSG values for the vehicle control group (n=4) averaged 83.02 ± 20.55 * p<0.05 relative to vehicle controls as determined by ANOVA with modified t-statistics (Bonferroni method).
