    Abstract:

    Benzophenone (BP) type ultraviolet (UV) filters are widely used in paints, coating materials and colorants. In order to investigate the occurrence of BP-type UV filters in painters, 10 urine samples from painters and other 10 urine samples from general population were collected in Harbin City. Urinary concentrations of five BP-type UV filters including 2-hydroxy-4-methoxy benzophenone (BP-3), 4-hydroxy benzophenone (4-HBP), 2, 4-dihydroxy benzophenone (BP-1), 2, 2′, 4, 4′-tetrahydroxy benzophenone (BP-2) and 2, 2′-dihydroxy-4-methoxy benzophenone (BP-8) were analyzed. The results indicated that the painters in Harbin were widely exposed to BP-3, 4-HBP, BP-2 and BP-8. BP-2 and BP-8 were the major BP-type UV filters. For all BP-type UV filters in painters, BP-3, 4-HBP and BP-2 shared the same origin, and 4-HBP and BP-8 shared the same origin.However, the BP-2 and BP-8 originated differently. The excretion doses of BP-type UV filters in painters were higher than that in general population, which indicated a possoble relationship between the exposure doses of BP-type UV filters and the working environment for painters. Long term exposure to paint or coating materials can increase the burden of BP-type UV filters in human.
