Oxidative Damage in Lymphocytes of Copper Smelter Workers Correlated to Higher Levels of Excreted Arsenic
Figure 2
Comparative effect of arsenic exposure on lipid peroxidation in blood samples from low- and high-exposure human populations. (a) Comparison of MDA distribution profile in blood samples isolated from low-As-exposure (control, ) and high-As-exposure () human populations. Lipid peroxidation was assessed by plasma MDA concentration. The statistical analysis indicates significant differences between the two groups (test U-Mann-Whitney ). (b) Correlation between MDA concentration and urinary excretion of As in the high As-exposure population (). The associations between the two variables were determined by -Pearson ().
