本研究旨在研究燃煤电厂周边不同植物叶片中多环芳烃（PAHs）的积累情况，并为PAHs污染监测寻找潜在的生物指标。研究在CPP周边地区的8个地点进行。在CPP 1 km范围内生长的21种植物叶片中的多环芳烃浓度范围为0.043 ~ 4.52µg g−1。多年生草本植物和灌木叶片中多环芳烃的平均浓度高于一年生草本植物和乔木。草本植物中5 ~ 6环多环芳烃含量最高，4环多环芳烃主要存在于灌木中。2 ~ 3环多环芳烃在草本植物、乔木和灌木间差异不显著。在此基础上，选取了4种具有代表性的植物，研究了CPP对多环芳烃化合物空间分布格局的影响。2 ~ 3环多环芳烃含量差异无统计学意义，4环、5 ~ 6环和Σ16PAHs存在区域统计学差异。多环芳烃（PAHs）sch - bip具有显著的区域统计学差异。随着距离的变化，多环芳烃的浓度显著降低。蒙古蒲公英对总多环芳烃和5 ~ 6环多环芳烃的捕获量均最大，对BaP的捕获量最大。这些结果可以改善筛选生物指标的科学依据，特别是T。蒙古可能是优先考虑的国家。
The purpose of this study was to investigate polycyclic aromatic hydrocarbons (PAHs) accumulation in leaves of different plant species growing in the neighborhood of coal-fired power plant (CPP) and to identify potential bioindicators for PAHs pollution monitoring. The study was performed in 8 sites in the surrounding areas of CPP. PAHs concentrations in leaves of 21 plant species growing within 1 km of CPP ranged from 0.043 to 4.52 µg g−1. A higher mean concentration of PAHs was found in leaves of perennial herbs and shrubs compared with annual herbs and trees. Herbaceous plants had the highest concentrations of 5–6 rings PAHs, and 4-ring PAHs mainly existed in shrubs. For 2- to 3-rings PAHs, there was no significant difference among herbaceous plants trees and shrubs. Then, four representative plants were further chosen for investigating the effect of CPP on the spatial distribution patterns of PAH compounds. No distinct difference in the level of 2- to 3-rings PAHs was observed onBroussonetia kaempferiSieb, whereas 4 rings, 5–6 rings, and Σ16PAHs had regional statistical differences. PAHs inKalimeris indica(L.) Sch.-Bip had significant regional statistical differences. With the change of distance, the concentration of PAHs showed a significant decrease.Taraxacum mongolicumtended to capture the largest amount of both total PAHs and 5- to 6-ring PAHs, especially to BaP. These results could improve scientific evidence for the screening of bioindicators, in particular,T. mongolicumcould be a priority.
