While there are increasing data on chemical mixtures in European water bodies, consistent data on chemical pollution in many countries of the Global South and on a global scale are extremely scarce. Thus, we established the Global Chemical Monitoring (GloCheM) network involving enthusiastic scientists from all continents to join forces and close existing data and knowledge gaps, and to improve chemical monitoring on a global scale. To facilitate the implementation of global sampling campaigns we contribute to the development of new sampling tools for easy and cost-effective water sampling.

So far, we have investigated chemical mixture in Western Kenya (Chepchirchir et al., 2024; Kandie et al., 2020a; Kandie et al., 2020b; Tanui et al., 2025a; Tanui et al., 2025b), in the megacity of Lahore, Pakistan (Shahid et al., 2025) and in Chile (Inostroza et al., 2024). In ongoing projects, we further explore chemical pollution in the Nile basin and the Sosiani River in Eldoret (Kenya).
