An Investigation and Analysis of Polluting Trend along Railway Line and Usable Ability Test of Snack Box with New Materials

为了消除铁路沿线的白色垃圾污染，铁道部对不可降解的餐盒进行了更新换代。本文通过对餐盒的污染动态试验和使用性能调查对新型快餐盒进行了筛选。结果为：污染动态试验２种类型的新型快餐盒污染曲线呈下降趋势，纸制餐盒尤其明显。而对照线、自线对照的污染曲线则呈上升趋势。使用性能试验按照５０％的满意程度，只有ｄ厂餐车工作人员的满意率没达到一半，其余各厂均达到和超过了５０％。说明就目前质量的餐盒使用，是可以被大多数人接受。从餐盒评价的排序结果来看，纸制品餐盒是最受使用部门欢迎的。
