Contamination of benzotriazole ultraviolet stabilizers in house dust from the Philippines: Implications on human exposure

Seven compounds of benzotriazole ultraviolet stabilizers (BUVSs) were determined in house dust samples collected from a residential area (Malate: n=17) and municipal dumping area (Payatas: n=20) in the Philippines. Total concentrations of the 7 BUVSs in house dust ranged from ND (not detected) to 10...

Zusammenfassung:	Seven compounds of benzotriazole ultraviolet stabilizers (BUVSs) were determined in house dust samples collected from a residential area (Malate: n=17) and municipal dumping area (Payatas: n=20) in the Philippines. Total concentrations of the 7 BUVSs in house dust ranged from ND (not detected) to 1020ng/g in Malate and ND to 277ng/g in Payatas. Among the target compounds, the most abundant BUVS was UV-234, with a median value of 84ng/g (ND-813ng/g) in Malate and 41ng/g (ND-212ng/g) in Payatas, respectively. Significantly higher concentrations of UV-326 (p
