Abstract

Polycyclic aromatic hydrocarbons (PAHs) in moss (Hypnum plumaeformae) samples collected from two retrial profiles on the northern slope of Nanling mountains were analysed qualitatively adopting. Accelerated solvent extraction jel chromatographic column (GPC) purification and GC-MS. The concentrations of phenanthrene was the highest in PAHs of the moss samples; the ∑PAHs range was 309.2-1342.4 ng/g dry weight, its composition possessed better correlation with the atmosphere deposition PAHs; the concentrations of most PAHs tended to decline in different degree with the increase of altitude. Through comparing with aerosols and gas phase PAHs the great flow sampler collected samples, it was discovered that the mosses tended more to accumulate high-molecular-weight PAHs; the concentrations of PAHs in the mosses weight PAHs and the atmosphere had quite good relatively.
