| Research Abstract |
UV filters in cosmetics and UV light stabilizers in polymer based products are important chemicals in our daily life. However there is increasing concern that they may release to rivers and coastal areas and give adverse effects on aquatic organisms like fishes and shells. In this study, multiresidual analysis method for measuring UV filter and UV light stabilizers in surface waters, sediments and aquatic biota were established. Furthermore their occurrence, distribution, persistence and bioaccumulation in rivers were investigated. It revealed that some of these chemicals were ubiquitous in aquatic environment.
