Outline of Final Research Achievements

Polycyclic aromatic hydrocarbons (PAHs) are widespread environmental pollutants that have become a serious global problem due to their toxicity and long-range transportation. In this study, the characteristics of PAH pollution was investigated using pine needles and mosses as bioindicators. In addition, the effective use of these bioindicators was examined. The study sites were alpine regions and their surrounding urban areas across central Japan. The results of this study revealed that (1) a stronger influence of transboundary PAH pollution from other East Asian countries on the northern coastal cities and alpine regions, (2) mosses can be good indicators for the assessment of transboundary PAH pollution, and (3) in contrast to mosses, pine needles strongly reflected the influence of domestic PAH pollution. These results demonstrate that pine needles and mosses can function as bioindicators and facilitate the assessment of PAH pollution from a different perspective.
