摘要:

根据广西5市1018名18岁学生体质调查资料和环境监测资料,用灰色理论的关联分析法研究环境污染物与青少年生长发育的关系。结果表明,学生身高、体重、肺活量、收缩压、舒张压与环境污染物的关联顺序基本相同,按其关联程度的大小依次为:工业废水或废气中的烟尘、废气中的SO₂含量、废气、工业废渣和废水中Pb含量,提示应密切关注工业废水、废气中烟尘和SO₂含量对青少年生长发育的影响。

Abstract:

Based on a national constitution survey of 1018 students aged 18 years and data of environmental monitoring in five cities of Guangxi, we studied the relationship between environmental pollutants and growth of students by using grey relation analysis. The results showed that related orders of environmental pollutants and height, weight, vital capacity, systolic BP and diastolic BP were similar. The related degree was in the order of industry waste water or smoke and dust in waste gas, content of SO₂ in waste gas, waste gas, industry waste residue, content of Pb in waste water. More attention should be paid that growth and development of students could be influenced by waste water, smoke and dust in waste gas, content of SO₂ in waste gas.
