Oxidative Damage in Lymphocytes of Copper Smelter Workers Correlated to Higher Levels of Excreted Arsenic
Figure 4
Comparative levels of SOD activity in plasma samples from low- and high-exposure human populations and correlation between SOD activity and urinary excretion of As from highly As-exposed population. (a) SOD activity in the plasma samples of the low-As-exposure group () and high-As-exposure group (). Data are graphed as mean standard error (). (b) Relationship between plasma SOD activity and As concentration in urine from highly exposed population (). Statistical differences of SOD activity between the groups were established according to U-Mann-Whitney test.
