摘要

塑料在农业和渔业中的使用对于提高粮食产量和满足日益增长的全球人口的需求至关重要。然而,塑料在这些行业的使用也存在一些弊端。农业中使用的大多数塑料在使用一次后就会被丢弃,而且极易风化。被遗弃、丢失或丢弃的渔具会对海洋生物造成严重损害。对这些行业产生的塑料废物进行量化的研究很少,甚至在渔业中根本不存在。在本文中,我们以英国西南部为例,估算了区域范围内农业和渔业产生的塑料垃圾数量。我们采用质量平衡法来量化这些行业可能产生的塑料废物。我们发现农业产生了 49 千吨塑料废物,其中 47% 的去向不明。我们估计每年产生 454 吨渔具废物,其最终去向不明。在区域范围内对各行业产生的塑料垃圾进行详细的定量了解,对于跟踪塑料垃圾流、定位污染热点以及规划行动以减少最终用户链上的塑料垃圾数量至关重要。

Quantification of Plastics in Agriculture and Fisheries at a Regional Scale: A Case Study of South West England
The use of plastics in agriculture and in fisheries has been vital to increase food production and meet the demands of an increasingly growing global population. However, there are several drawbacks to the use of plastics in these industries. Most plastics used in agriculture are disposed of after one single use and are highly susceptible to weathering. Abandoned, lost, or discarded fishing gear cause considerable damage to marine life. Quantification of plastic waste generation in these industries is scarce or non-existent in the case of fisheries. In this paper, we estimate the amount of plastic waste generated by agriculture and fisheries at a regional scale, considering the South West of the UK as a case study. We followed a mass balance approach to quantify the potential plastic waste generated by these industries. We find a generation of 49 kt of plastic waste in agriculture, 47% of which has an unknown fate. We estimate 454 t/year of fishing gear waste, with unclear end-of-life pathways. A detailed quantitative understanding of plastic waste generation per sector at a regional scale is fundamental for tracking plastic waste flows, locating hotspots of pollution, and planning actions to reduce the amount of plastic waste along the chain of end-users.
