Figure 2From: Biomarkers of oxidative stress and its association with the urinary reducing capacity in bus maintenance workersCorrelation between 8OHdG and reducing species. (a) Correlation between urinary levels of 8OHdG (in μg/g creatinine) and reduced species (in μW/g creatinine) for all collected samples. (b) Correlation between within-shift variation of 8OHdG (% of initial value) and within-shift reduced species (% of initial value) for smokers and non smokers.Back to article page
