Short summary
A total of 86 polycyclic aromatic compounds (PACs), toxic compounds mainly emitted after fossil fuel combustion, were measured during 8 months in the urban air of Longyearbyen (78° N, 15° E), the most populated settlement in Svalbard. Contrary to a stereotype of pristine Arctic conditions with very low human activity, considerable PAC concentrations were detected, with spring levels comparable to European levels. Air pollution was caused by local snowmobiles in spring and shipping in summer.
