Abstract

Monitoring atmospheric pollution in urban areas is challenging because pollutant deposition occurs at short distances, requiring a large amount of sampling and analysis to characterize it. Ecological indicators can help overcome this problem, allowing us to select sites with the highest deposition of pollutants from the atmosphere. Nevertheless, a major gap is the temporal characterization of the accumulation rate of magnetic particles in ecological indicators, which is critical to understand if the bioaccumulation process is linear or if saturation occurs. To overcome this problem, Parmotrema perlatum lichens were magnetically and chemically studied in a pollution gradient over space and time. Lichen transplants were exposed over 18 weeks to a high-traffic road. Results show that magnetic properties and element composition reflected both distance from the road (nonlinear decrease of up to 100 m from source) and exposure time (increasingly linearly over the entire study period with eightfold increments), showing that up to 18 weeks, the accumulation rate remained constant over time, with no saturation occurring. Chemical analysis showed a strong linear relationship between the accumulation of zinc (Zn), antimony (Sb), manganese (Mn), copper (Cu) chromium (Cr) and magnetic susceptibility. Magnetization acquisition curves reveal a time-dependent low-coercivity component, interpreted as mainly related to nonexhaust, mostly brake abrasion particle emissions. It is concluded that the magnetic properties of lichen transplants can be used in urban environments to characterize the spatial and temporal patterns of the deposition of pollution metallic particles from the atmosphere.

地衣移植用于空气中微粒物质的磁性和化学生物监测:葡萄牙里斯本时空研究
监测城市地区的大气污染具有挑战性,因为污染物的沉积距离很短,需要进行大量的取样和分析才能确定其特征。生态指标有助于克服这一问题,使我们能够选择大气污染物沉积量最大的地点。然而,生态指标中磁性微粒累积率的时间特征描述是一个主要空白,这对于了解生物累积过程是线性还是饱和至关重要。为了解决这个问题,我们在污染梯度的空间和时间范围内对 Parmotrema perlatum 地衣进行了磁学和化学研究。地衣移植体暴露在交通繁忙的道路上长达 18 周。结果表明,磁性和元素组成反映了与道路的距离(距离污染源 100 米处非线性减少)和暴露时间(在整个研究期间呈线性增加,增加了 8 倍),表明在 18 周内,积累率随时间保持不变,没有出现饱和现象。化学分析显示,锌(Zn)、锑(Sb)、锰(Mn)、铜(Cu)、铬(Cr)的积累与磁感应强度之间存在很强的线性关系。磁化采集曲线显示了随时间变化的低矫顽力成分,这主要与非废气(主要是制动磨损颗粒排放物)有关。结论是,在城市环境中,地衣移植体的磁特性可用于描述大气污染金属颗粒沉积的空间和时间模式。
