Web“The current photolytic degradation experiments were performed on DBDPE in solvents and on silica gel. Large differences in the photolytic degradation behaviors of DBDPE may exist between lab matrixes and the natural environmental media such as atmospheric particles, soil, and water as suggested previously for deca-BDEs (Raff and Hites, 2007). WebIV. Photolytic Debromination of BDE 209 BDE 209 absorbs sunlight in the UV region of the electromagnetic spectrum that reaches the surface of the earth. Due to this light absorption, BDE 209 is susceptible to photodegradation, which can occur significantly through debromination. A majority of the UV spectrum is blocked by glass windows and
