The actual rate of volatilization of plasticizers from water apparently has not been experimentally measured. The rates of volatilization, however, estimated using the Sonth-worth Method to estimate gas-phase and liqnid-phase mass transfer coefficients, were reported in HSDB, and summarized in Table 18.10. VolatiUzation was estimated nnder two scenarios (Figure 18.1) a shallow (1-m deep) river moving at a rate of 1 m/sec below an air mass moving at 3 m/sec. The second scenario was a shallow (1-m deep) lake moving at 0.05 m/sec below a breeze of 0.5 m/sec. The estimated volatilization half-lives of the plasticizers followed the trend established by their Heniy Law constants. Consequently, the predicted half-lives of ditridecyl phthalate, di-(2-ethylhexyl) adipate, di-(2-ethylhexyl) azelate, diundecyl, diisooctyl, dihexyl, dinonyl phthalate were less than 6 days. The same plasticizers would likely be more persistent in the lake scenario. The volatilization rates of the other plasticizers appeared to be much slower, and volatilization from water may not be a significant environmental pathway. Furthermore, the Southworth estimation technique does not take into acconnt sorption of dissolved chemicals by suspended particles. Sorption would increase the residence time of dissolved plasticizers. The predicted volatilization rates, however, were based on Hemy s Law constants which are themselves only estimates.
