Abstract

For the first time, the concentration of plastic particles in surface water of Lake Baikal was evaluated. The concentrations of plastic particles were evaluated in trawl samples taken in the coastal zone of the most densely populated southeastern coast and in the Maloe More―one of the most popular tourist zones in Baikal. Converted to water surface area, the concentration of plastic particles varied from 19 000 to 75 000 per 1 km², at an average of 42 000 particles per 1 km², suggesting a high level of plastic pollution. By their chemistry, the particles were classified as polyethylene, polypropylene, and polystyrene. The microplastic found in the study is assumed to be the product of decay of various domestic packing materials.

贝加尔湖中南部沿海地表水的塑料污染

摘要

首次评估了贝加尔湖地表水中塑料颗粒的浓度。在人口最稠密的东南沿海地区和贝加尔湖最受欢迎的旅游区之一的玛洛莫尔（Maloe More）的拖网样本中评估了塑料颗粒的浓度。转化为水的表面积，塑料颗粒的浓度从19到000 75 000改变每1km ²，在平均42个000粒子的每1km ²，这表明塑料污染的高水平。根据它们的化学性质，将颗粒分类为聚乙烯，聚丙烯和聚苯乙烯。研究中发现的微塑性被认为是各种家用包装材料的腐烂产物。
