PAH concentrations in smooth cordgrass (Spartina alterniflora) tissue and semipermeable membrane devices in a crude oil contaminated salt marsh

This dataset includes the concentrations of polycyclic aromatic hydrocarbons (PAHs) in 3 fractions on the smooth cordgrass (Spartina alterniflora) 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. Soil concentrations were collected on several dates for comparison. This data reflects the continued cycling of PAHs through marsh vegetation years following the Deepwater Horizon oil spill.

本数据集包含互花米草（Spartina alterniflora）叶片三个组分中的多环芳烃（polycyclic aromatic hydrocarbons, PAHs）浓度，分别为叶片表面颗粒物结合态PAHs、分配至叶片角质层的PAHs，以及剩余叶片组织中的PAHs。研究同步采集了该植物冠层及潮滩表面半透膜装置（semipermeable membrane devices）中的PAHs浓度，与上述叶片采样同步进行。为便于对比，研究团队还在多个日期采集了土壤中的PAHs浓度数据。本数据集反映了深水地平线漏油事件（Deepwater Horizon oil spill）发生多年后，多环芳烃通过潮滩植被持续循环的过程。
