An overview of analytical methods and occurrence of benzotriazoles, benzothiazoles and benzenesulfonamides in the environment

• Analytical methods for benzotriazoles, benzothiazoles and benzenesulfonamides.
• We review the occurrence of benzotriazoles, benzothiazoles and benzenesulfonamides.
• LC-MS/MS determines benzotriazoles, benzothiazoles and benzenesulfonamides most often.
• Critical steps in analysis of benzotriazoles, benzothiazoles and benzenesulfonamides.

Benzotriazoles, benzothiazoles and benzenesulfonamides are high-volume production chemicals widely used in industry and households every day. They are highly soluble in water and some resist biodegradation and/or have toxic effects. They have already been classified as emerging organic pollutants, and some are considered ubiquitous water contaminants.We review the analytical methods currently employed for the determination of benzotriazoles, benzothiazoles and benzenesulfonamides in aqueous and solid environmental matrices, and their occurrence in river water, sewage, soil, sediment and sewage sludge. Furthermore, we provide data and information on their removal and their behavior during sewage treatment.
