Abstract

We investigated the effectiveness of high-density polyethylene (HDPE) covers in reducing landfill emissions of hydrogen sulphide (H₂S), ammonia (NH₃), and inhalable particulate matter smaller than 10 μm in diameter (PM₁₀) at the Waste Management Centre Marišćina (Croatia) by comparing air quality data from 2018, prior to the installation of the HDPE cover, with data from 2021, post-installation. The results demonstrate a significant reduction in H₂S and PM₁₀ concentrations (36.76 % and 24.18 %, respectively). However, NH₃ levels unexpectedly increased by 20.48 %, suggesting the presence of additional sources of ammonia in the vicinity of the centre or changes in landfill microenvironment. Our findings highlight the effectiveness of HDPE covers in controlling specific landfill emissions and the need for a comprehensive environmental management strategy to address all pollutants. Future research should also investigate the long-term effects of HDPE cover on landfill emissions and how they could contribute to broader environmental goals, such as reducing greenhouse gas emissions and improving air quality.

减少垃圾填埋气体排放：HDPE覆盖层在降低大气中H2S、NH3和PM10浓度方面的有效性。

我们通过比较2018年（HDPE盖安装前）和2021年（安装后）的空气质量数据，研究了高密度聚乙烯（HDPE）盖在减少垃圾填埋场硫化物（H2S）、氨（NH3）和直径小于10 μm的可吸入颗粒物（PM10）排放方面的有效性。结果表明，H2S和PM10浓度显著降低（分别为36.76%和24.18%）。然而，NH3水平意外地增加了20.48%，表明在中心附近存在额外的氨源或垃圾填埋场微环境发生了变化。我们的研究结果强调了HDPE覆盖在控制特定垃圾填埋场排放方面的有效性，以及解决所有污染物的综合环境管理战略的必要性。未来的研究还应该调查HDPE覆盖对垃圾填埋场排放的长期影响，以及它们如何有助于更广泛的环境目标，例如减少温室气体排放和改善空气质量。
