Polycyclic aromatic hydrocarbons (PAHs) concentrations in Avicennia germinans plant tissue and semipermeable membrane devices in a crude oil contaminated salt marsh

This dataset includes the concentrations of polycyclic aromatic hydrocarbons (PAHs) in three fractions on the Avicennia germinans (black mangrove) leaf (PAHs in particles on the leaf surface, PAHs partitioned into the leaf cuticle and PAHs in the remaining leaf tissue. PAH concentrations in semipermeable membrane devices in the plant canopy and on the marsh surface were collected simultaneously with these leaf measurements. Finally, marsh soil PAH concentrations were collected on several dates for comparison. These data reflect the continued cycling of PAHs in marsh vegetation years after the spill.本数据集涵盖了海榄雌（Avicennia germinans，俗称黑红树）叶片中三个组分的多环芳烃（polycyclic aromatic hydrocarbons, PAHs）浓度，分别为叶片表面颗粒物结合态多环芳烃、分配至叶片角质层的多环芳烃，以及剩余叶片组织中的多环芳烃。研究人员同步采集了植物冠层及潮滩表面半透膜装置中的多环芳烃浓度，与上述叶片样品检测同步开展。最后，为开展对照分析，研究人员在多个采样日期采集了潮滩土壤的多环芳烃浓度。这些数据反映了溢油发生数年后，潮滩植被中多环芳烃仍在持续循环。
