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.
