The blood lead levels of 1879 children were normal distribution with mean and standard deviation of 7.33μg / dl and 5.46μg / dl, respectively, with a median of 6.6μg / dl ranging from 0.1 to 75.0μg / dl Significant difference. There were 448 lead poisoning persons accounting for 23.84% of the total. Among them, the incidence of lead poisoning among urban children was the highest (39.55%), followed by rural areas, mountainous areas and islands, which were 27.57%, 14.24% and 11.68% respectively.
