农田微塑料污染现状及分析评价方法研究

Research on the Current Situation and Analysis and Evaluation Methods of Microplastic Pollution in Farmland

摘要: 随着生产技术的不断进步，塑料这一高分子合成材料在经济性、效率性和可替代性方面展现出明显的优势，使用量也逐年增加。然而，由于处理不当，大部分废弃塑料未能得到有效回收，而是大量积聚在水域和陆地环境中。这些塑料在自然环境中经过物理和化学作用，逐渐破碎成微小的塑料颗粒，即微塑料。微塑料污染已经成为环境问题的重要代表。本文将重点探讨农田中微塑料污染现状及现有的分析评价方法，并提出相应的防控策略，为解决这一问题提供参考。

Abstract: With the continuous progress of production technology, plastics, as a polymer synthetic material, have shown obvious advantages in economy, efficiency, and substitutability, and their usage has also increased year by year. However, due to improper handling, most of the discarded plastic has not been effectively recycled, and instead accumulates in large quantities in water and land environments. These plastics undergo physical and chemical reactions in the natural environment, gradually breaking into tiny plastic particles, known as microplastics. Microplastic pollution has become an important representative of environmental problems. This article will focus on exploring the current situation of microplastic pollution in farmland and existing analysis and evaluation methods, and propose corresponding prevention and control strategies to provide reference for solving this problem.
