They have complex stracture and abundant in the universe. U.S. EPA listed 16 PAHs as priority pollutants in 1979 based on their amount and biotoxicity in the environment. Human exposed to PAHs by three pathway i.e. ingestion, inhalation and dermal contact routes. This study used the system dynamics software STELLA to develop a novel PAHs Dynamic Multimedia Transport (DMT) model. The PAHs levels in each environmental compartment and biota are simulated to calculate life time average daily dose (LADD) for the citizens of Taiwan. The Air Resource Co-benefits (ARCoB) model was applied to estimate the costs and co-benefits of emission reductions in criteria air pollutants (CAPs), greenhouse gases (GHG) and PAHs. Iron and Steel Industry and supercritical fluid extraction (SFE) were chosen as case studies. iii By the target year of 2025, the investment costs of emission reductions (installation costs add operational costs) in Case1-1 and Case1-2 were estimated to be NT$ 6,270 and 20,834 million/yr, respectively. And the total benefits in Case1-1 and Case1-2 was estimated to be NT$ 14,759 and 49,179 million/yr. The results of cost-benefit analysis demonstrate that the benefit-cost ratio of 2.36 for Case1-2 will be higher than that of 2.35 for Case1-1.
