Abstract
Tetrabromobisphenol A or TBBPA is a widely used brominated flame retardant in modern materials such as electronic products, plastics and building materials. TBBPA can leach out of flame retardant-treated products during production, use, reuse, and final disposal of these consumer products. It has thus become a contemporary environmental contaminant. This study reports the levels of TBBPA in indoor dust from houses (n=4) and internet cafes (n=5) in Angono and Quezon City, in the Philippines. TBBPA in indoor dust was analyzed by ultrasonication-assisted hexane extraction and HPLC-UV determination. The instrument and method detection limits were 0.004 ng uL-1 and 1275 ng g-1, respectively. The standard calibration solutions ranged from 0.03 to 0.30 ng uL-1 (r2=0.9956). The extraction recovery was 78% (n=3. TBBPA was found in six of the nine indoor dust samples studied where the concentrations ranged from not detected to 4916 ng g-1. The occurrence and levels of TBBPA in indoor dusts are significant and suggest the need for further investigations especially in other microenvironments where people may be exposed to this contaminant.
