Sources-attributed contributions to health risks associated with PM-bound polycyclic aromatic hydrocarbons during the warm and cold seasons in an urban area of Eastern Asia.

Despite the well-established recognition of the health hazards posed by PM-bound PAHs, a comprehensive understanding of their source-specific impact has been lacking. In this study, the health risks associated with PM-bound polycyclic aromatic hydrocarbons (PAHs) and source-specific contributions were investigated in the urban region of Taipei during both cold and warm seasons. The levels of PM-bound PAHs and their potential health risks across different age groups of humans were also characterized.
