Abstract

Aircraft operations at an airport result in the emission of various substances. Simultaneously, in an airport area, road traffic is very intense, also contributing to the emission of the same substances. In this work, potentially toxic elements (PTEs), essentially trace metals, and others not categorized as such (alloys elements and ceramic particles that constitute particulate matter) are considered, which end up being deposited on soils. The main purpose of this study is to identify soil quality degradation potentially connected to aircraft operations related to Lisbon Airport. At the same time, an attempt is made to differentiate the contribution of soil quality degradation resulting from road traffic. Several geotechnical and chemical parameters are determined for all the 102 collected samples. X-ray fluorescence analysis is performed to identify and quantify the main elements present in all samples. Some samples are also subjected to X-ray diffraction to determine the mineralogical composition. The data obtained allow the creation of distribution maps of the detected elements and, after multivariate statistical analysis, conclude which ones are related to very intense road traffic and which ones are related to aircraft-traffic emissions, in an urban area, based on a holistic interpretation of all intervenient variables.

空气和道路交通造成的城市土壤质量退化——相关信息和研究

在机场飞行的飞机会排放各种物质。同时，在机场区域，道路交通非常繁忙，也导致了同样物质的排放。在这项工作中，潜在有毒元素(pte)，基本上是微量金属，以及其他未被归类为此类的元素(合金元素和构成颗粒物质的陶瓷颗粒)被考虑在内，它们最终沉积在土壤中。本研究的主要目的是确定与里斯本机场相关的飞机运行可能相关的土壤质量退化。同时，试图区分道路交通造成的土壤质量退化的贡献。对收集的102个样品确定了若干岩土和化学参数。进行x射线荧光分析，以确定和量化所有样品中存在的主要元素。有些样品还经过x射线衍射来确定矿物成分。获得的数据可以绘制所探测到的要素的分布图，并在进行多元统计分析后，根据对所有干预变量的整体解释，得出在城市地区哪些与非常密集的道路交通有关，哪些与飞机交通排放有关的结论。

期刊介绍： In 21st century living, engineers and researchers need to deal with growing problems related to climate change, oil and water storage, handling, storage and disposal of toxic and hazardous wastes, remediation of contaminated sites, sustainable development and energy derived from the ground. Environmental Geotechnics aims to disseminate knowledge and provides a fresh perspective regarding the basic concepts, theory, techniques and field applicability of innovative testing and analysis methodologies and engineering practices in geoenvironmental engineering. The journal''s Editor in Chief is a Member of the Committee on Publication Ethics. All relevant papers are carefully considered, vetted by a distinguished team of international experts and rapidly published. Full research papers, short communications and comprehensive review articles are published under the following broad subject categories: geochemistry and geohydrology, soil and rock physics, biological processes in soil, soil-atmosphere interaction, electrical, electromagnetic and thermal characteristics of porous media, waste management, utilization of wastes, multiphase science, landslide wasting, soil and water conservation, sensor development and applications, the impact of climatic changes on geoenvironmental, geothermal/ground-source energy, carbon sequestration, oil and gas extraction techniques, uncertainty, reliability and risk, monitoring and forensic geotechnics.
