Abstract

Trees are considered to be an effective tool for metal pollution biomonitoring. In the present study, the concentration of metals (Cu, Pb, Zn, Cd, Co, Ni, Fe, Mn, and Al) in black poplar leaves ( L.), together with the concentration of PM, PM, PM, and total suspended particles (TSP), was used for the air pollution biomonitoring in 12 sites from various areas of Cluj-Napoca city, Romania. The concentration of PM in the air was high, but their metal content was low. However, Cu, Pb, and Zn were moderately enriched, while Cd was highly enriched in PM due to anthropogenic sources. The average metal concentration in leaves decreased in the order Zn>>Fe>Mn>Al>Pb>Ni>Cu>Co>Cd and increased with the increase of PM concentration, indicating that poplar leaves are sensitive to air pollution. The principal component analysis indicated that traffic, waste burning, road dust resuspension, and soil contamination are the main anthropogenic sources of metals in poplar leaves. The results indicated that black poplar leaves are a suitable biomonitoring tool for metal pollution, in urban environments.

摘要

树木被认为是金属污染生物监测的有效工具。在本研究中,罗马尼亚克卢日-纳波卡市不同区域的12个地点,利用黑杨树叶中的金属(铜、铅、锌、镉、钴、镍、铁、锰和铝)浓度,以及PM 、PM 、PM和总悬浮颗粒物(TSP)的浓度进行空气污染生物监测。空气中PM的浓度较高,但其金属含量较低。然而,由于人为来源,铜、铅和锌有中度富集,而镉在PM中高度富集。树叶中金属的平均浓度顺序为锌>>铁>锰>铝>铅>镍>铜>钴>镉,并随PM浓度的增加而增加,表明杨树叶片对空气污染敏感。主成分分析表明,交通、垃圾焚烧、道路扬尘再悬浮和土壤污染是杨树叶中金属的主要人为来源。结果表明,在城市环境中,黑杨树叶是金属污染的合适生物监测工具。
