The Effect of a Short-Term Exposure to Lead on the Levels of Essential Metal Ions, Selected Proteins Related to Them, and Oxidative Stress Parameters in Humans

Table 4

Correlations between lead-induced changes of the levels of lead, MDA, and LPH and the changes of the levels of essential metals, activities of antioxidant enzymes, and the levels of oxidative stress markers and ceruloplasmin. S: serum; E: erythrocyte; L: leukocyte; D: a difference between the levels at baseline and at the end of the study period.
