Spatial and Temporal Distributions of Polycyclic Aromatic Hydrocarbons in Sediments from the Canadian Arctic Archipelago
<p>The concentrations of 23 polycyclic aromatic hydrocarbons (PAHs; 16 parent and 7 alkylated PAHs) in 113 surface marine sediment samples, 13 on-land sediment samples and 8 subsampled push cores retrieved from the Canadian Arctic Archipelago (CAA) were calculated. PAHs were extracted...
