UV filters are classified as environmental pollutants (emerging pollutants). One of the most frequently detected UV filters in real samples is 2-phenylbenzimidazole-5-sulfonic acid (PBSA). It has been shown that conventional technologies applied in sewage treatment plants are not adapted for complete removal of sunscreen agents.

The subject of this study is 2-phenylbenzimidazole-5-sulfonic acid (PBSA), which is one of 26 filters used for personal protection in the European Union. The aim of the study was to investigate the stability of 2- phenylbenzimidazole-5-sulfonic acid and its sodium salt under the influence of various agents. The study has shown that UV radiation, pH value, hydrogen peroxide are important factors limiting...
