Additional information

The phototransformation in air was investigated using the SRC AOP v1.92 estimation tool. AOPwin is an application contained in the EpiSuite 4.1, the suite of physical/chemical property and environmental fate estimation programs developed by the EPA’s Office of Pollution Prevention Toxics and Syracuse Research Corporation (SRC).
