Some key parameters such as gasoline vapor mole quality and compression factor, vapor pressure, and vapor-airdiffusion coefficient were decided and recommended.
Airdiffusion can impact the pollutant distribution in atmosphere, and so do some non-diffusion aspects such as dry sediment, wet sediment and chemical translation.
