Treatment of particle/gas partitioning using level III fugacity models in a six-compartment system

In this paper, two level III fugacity models are developed and applied using an environmental system containing six compartments, including air, aerosols, soil, water, suspended particulate matters (SPMs), sediments, as a “unit world”. The first model, assumes equilibrium between air aerosols water SPMs. These assumptions lead to four-fugacity model. second model removes these leading six-fugacity models, compared four PBDE congeners, BDE-28, -99, −153, −209, with steady flux of gaseous congeners entering the following conclusions. 1. When octanol-air partition coefficient (KOA) is less than 1011.4, produce similar results; when KOA > especially 1012.5, results diverge significantly. 2. Chemicals in imposed but state not necessary aerosols. 3. from indicate internally consistent chemicals all whereas presents inconsistent where 4. mass balanced predicted by If balance achieved condition will be no longer valid.
