Atmospheric, soil, and feces samples were collected in Ny-Ålesund during July 2015. The concentrations, distributions, congener profiles, and contaminant migration levels were analyzed for 16 polycyclic aromatic hydrocarbons (PAHs) identified by the United States Environmental Protection Agency (US EPA) as priority contaminants (16 PAHs). Mean concentrations in the gas and particle phases were 37.8 ng m⁻³ and 2.9 ng m⁻³, respectively, and mean concentrations in soil and reindeer/bird feces were 329.1 ng g⁻¹ and 720.7 ng g⁻¹, respectively, on a dry weight (d.w.) basis. In more than three phases, naphthalene and phenanthrene dominated the concentrations of the 16 total PAHs (Σ₁₆PAH) and the concentration of PAHs in the gas phase was much higher than in the particle phase. The main sources of local PAHs may be coal combustion and air-surface exchange. There was a volatilization tendency from soil to air for 2–4 ring PAHs, and exchange fluxes were ~ 10⁵ times greater than the deposition fluxes of 5–6 ring PAHs. The underground migration of PAHs was investigated in Ny-Ålesund; the results showed flux values of ~ 0.07% from the initial PAH concentrations.

2015年7月在Ny-Ålesund收集了大气，土壤和粪便样品。分析了美国环境保护署（US EPA）鉴定的16种多环芳烃（PAH）的浓度，分布，同类物和污染物迁移水平。 ）作为优先污染物（16个PAH）。气相和颗粒相的平均浓度分别为37.8 ng m ^-3和2.9 ng m ^-3，土壤和驯鹿/鸟粪的平均浓度分别为329.1 ng g ^-1和720.7 ng g ^-1。干重（dw）为基础。在多于三相，萘和菲为主的总共16种多环芳烃的浓度（Σ ₁₆PAH）和气相中PAHs的浓度远高于颗粒相。局部多环芳烃的主要来源可能是煤炭燃烧和空气表面交换。有从土壤中挥发的倾向于空气中2-4环PAHs和交换通量分别为〜10 ⁵比的5-6个环多环芳烃沉积通量更大倍。在Ny-Ålesund对PAHs的地下迁移进行了研究。结果表明，相对于初始PAH浓度，通量值为〜0.07％。
