We investigated the effectiveness of high-density polyethylene (HDPE) covers in reducing landfill emissions of hydrogen sulphide (HS), ammonia (NH), and inhalable particulate matter smaller than 10 μm in diameter (PM) 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 HS and PM concentrations (36.76 % and 24.18 %, respectively). However, NH 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.
我们通过比较克罗地亚马里什奇纳废物管理中心2018年（高密度聚乙烯（HDPE）覆盖层安装前）和2021年（安装后）的空气质量数据，研究了HDPE覆盖层在减少该填埋场硫化氢（HS）、氨（NH）和直径小于10μm的可吸入颗粒物（PM）排放方面的有效性。结果表明，HS和PM浓度显著降低（分别降低了36.76%和24.18%）。然而，NH水平意外上升了20.48%，这表明该中心附近存在额外的氨源或填埋场微环境发生了变化。我们的研究结果突出了HDPE覆盖层在控制特定填埋场排放方面的有效性，以及制定全面环境管理策略以应对所有污染物的必要性。未来的研究还应调查HDPE覆盖层对填埋场排放的长期影响，以及它们如何有助于实现更广泛的环境目标，如减少温室气体排放和改善空气质量。
