Abstract Objective To learn the changes of blood lead levels and serum biochemical parameters of the school age children from different areas. Methods All research objects,the school age children,were from three different areas respectively,including a mountainous area （L area）,an island area （H area） where there is not history of Pb pollution,and an industry area （N area） in relation to Pb pollution. The morning urine and peripheral venous blood samples were collected from the school age children. Pb in blood （PbB）,δ-aminoaevulinic acid in urine （ALA）,Ca²⁺,BUN,Cr in serum,and Thyroid Stimulating Hormone （TSH）,thyroxin （T4）,free thyroxin （FT4） levels were detected. Results PbB levels [M was 36.0 ppb] of the school age children from N area were significantly higher than that of L area [22.0 ppb] and H area [23.8 ppb]. On the contrary,serum Ca²⁺ levels of the school age children from N area were significantly lower than that of L area and H area. Serum T4 of N area was significantly lower than that of L area and H area. Serum FT4 of H area was significantly higher than that of L area and N area. And TSH of N area and H area were both obviously lower than that of L area. But all of these thyroxin indexes were in the range of normal values. Conclusion It should be widely concerned that the significant elevation of PbB levels may have a negative impact on school age children in the future.
