【摘要】 "白色污染"成为21世纪最严重的环境污染问题之一,已经受到各国专家学者的关注。通过对滇池南部沿岸滩涂环境中塑料分布情况进行研究,发现滇池南部沿岸各样点塑料丰度达0-56.44个/m~2不等,且农村区域明显高于湿地公园区域;颜色以白色(66.2%)、透明(23.3%)为主;种类以泡沫(49.1%)和薄膜(13.94%)尤为丰富;通过采用拉曼光谱对塑料进行成分鉴定发现主要存在PE、PET、PP、PS和PVC五种材质,且呈现分布数量PS>PE>PET>PP>PVC的关系。综合发现农业活动和渔业活动是影响滇池南部沿岸塑料垃圾分布最主要的因素。更多还原

【Abstract】 "White pollution" has become one of the most serious environmental pollution problems in the 21 st century and has attracted the attention of experts and scholars all over the world. By studying the distribution of plastics in the tidal flats in the south bank of DianLake, it was found that the number of plastics in the east and south bank of Dian Lake varied from 0 to 56.44/m~2, and the rural area was significantly higher than the wetland park area. The color was mainly white(66.2%) and transparent(23.3%). The types of foams(49.1%) and thin films(13.94%) were the most abundant. By using Raman spectroscopy to identify plastic materials, it is found that there are mainly five materials, PE, PET, PP, PS and PVC, and the distribution quantity is PS>PE>PET>PP>PVC. It is found that agricultural activities and fishing activities are the most important factors affecting the distribution of plastic waste in the east and south bank of Dian lake.更多还原
