The purpose of this study was to determine if the use of "earthenware dishes" is associated with high blood lead levels in children. Measurements of lead in blood were done in 169 school-children. Of this sample 100 children were selected: 50 of them with the lowest concentration of lead in blood and 50 with the highest. A questionnaire was applied to 39 mothers of the children with low blood lead levels (< 20.2 micrograms/dl) and 48 mothers of the children with high blood lead levels (> 28.0 micrograms/dl). Results show that the use, frequency and time of utilization of this type of dishes is statistically associated with high levels of lead in blood.
本研究的目的是确定使用“陶制餐具”是否与儿童血铅水平升高有关。对169名学童进行了血铅测量。从这个样本中选取了100名儿童：其中50名血铅浓度最低，50名血铅浓度最高。对血铅水平低（<20.2微克/分升）的39名儿童的母亲和血铅水平高（>28.0微克/分升）的48名儿童的母亲进行了问卷调查。结果表明，这种类型餐具的使用、使用频率和使用时间与血铅水平升高在统计学上相关。
