观察无特别重金属污染记录的某地区3岁儿童尿中重金属水平以及它们与儿童生长发育的关系,为预防重金属对儿童健康影响提供科学依据。研究人员选取江苏某县3岁儿童461名,收集随机尿样,使用电感耦合等离子体质谱仪(ICP-MS)检测铅、汞、镉水平,测量儿童身高、体质量、头围和胸围,用“Gesell量表0～3岁智力发育诊断量表”评估智能发育状况,用SPSS 16.0分析暴露与健康效应之间关系。结果显示尿中铅、汞及镉的浓度均呈非正态分布,
To observe the urinary levels of heavy metals and their relationship with children’s growth and development in 3-year-old children in a certain area without any record of heavy metal pollution and provide a scientific basis for preventing the impact of heavy metals on children’s health. The researchers selected 461-year-old children from a county in Jiangsu province to collect random urine samples and measure the levels of lead, mercury and cadmium by inductively coupled plasma mass spectrometry (ICP-MS). The height, body mass, head circumference and chest circumference “Gesell scale 0 to 3 years old mental development diagnostic scale ” to assess the intelligence development status, SPSS 16.0 analysis of the relationship between exposure and health effects. The results showed that urinary lead, mercury and cadmium concentrations were non-normal distribution,
