GSH (μMol / mL) and GSSG (μMol / mL) levels and GSH/GSSG ratio in groups of occupational exposure and not exposed group. GSH and GSSG results for subgroups A, B, C, D shown nearly values in the scale for which it is observed as a single point in the graph. p values were obtained with a one-way ANOVA test at 95% confidence level. The significance value is shown for the comparison of the unexposed group with the four occupational exposure subgroups of GSH and GSSG (a, b, c, d; p = 0.000), and for the GSH / GSSG ratio (a, b, c, d; p = 0.710)
