1.2- Dibromo-3-chloropropane model

Glaze et al. (1995) proposed a kinetic model for the UV/H202 oxidation using radical and the direct photolysis of the organic compounds. The model utilized the literature values of the rate constants for radical formation and substrate oxidation. It was applied to interpret the data from the oxidation of l,2-dibromo-3-chloropropane (1,2-DBCP) at low levels (less than 500 pg/ L) in simulated and actual groundwater.

UV/H202 oxidation of VOCs has also been studied in detail and several studies reported kinetic models to predict the efficiency of the process. For example, Liao and Gurol [75], Glaze et al. [113], De Laat et al. [155] and Crittenden et al. [74] studied the UV/H202 oxidation of VOCs such as n-chlorobutane, 1,2-dibromo-3-chloropropane and tri- and tetra-chloroethanes in batch photoreactors with low-pressure mercury vapor lamps. Effects of pH, concentration of hydrogen peroxide, UV intensity and the presence of carbonates or fulvic substances were variables studied. 

Better animal models need to be developed to accurately detect subtle changes in reproductive performance. Chemicals such as diethylstilbesterol and 1,2-dibromo-3-chloropropane have heightened the concern of toxicologists and the public in this important area of research.
