The figure shows the total of 32 PAHs in the air at seven urban sites in Gothenburg, and in the Botanical Garden’s arboretum. The Y axis shows an average value of the measurements in June and September 2018. The amount is given in ng/m3 air, i.e., in nanograms per cubic metre of air. There are no establish threshold level, but the researchers argue that the results are an important starting point for future risk assessments.
