Applicant's summary and conclusion
- Executive summary:
The environmental distribution and transport of dipropylene glycol methyl ether acetate (DPMA) between environmental compartments (air, water, soil, and sediments) was predicted using a Level III fugacity model. Input values required by the model include molecular weight, melting point, water solubility, vapor pressure, and octanol/water partition coefficient. In addition to these parameters, the model requires input of measured or estimated half-lives for reaction in air, water, soil, and sediments. The model incorporates transport rates into and between environmental compartments, and allows for losses of the compound due to advection or degradation processes.
This substance has high water solubility, a very low vapor pressure, and low log Kow. The substance therefore has a low potential for adsorption to soil or sediments, and a low potential to volatilize from water or soil to the atmosphere. If released to air, the substance will react with hydroxyl radicals. If released directly to water, the most probable emission route based on physical properties and use patterns, most of the substance will remain in the water compartment and is expected to be biodegraded. If released to soil, the substance is expected to be biodegraded. These modeling calculations, and associated input emission rates and output environmental concentrations, are intended solely to illustrate potential for distribution and transport of the substance among environment compartments. These results are not intended for use in derivation of predicted environmental concentrations (PEC) for specific compartments and/or use patterns.
