    Sammanfattning : The environmental toxin PFAS (per- and polyfluorinated alkyl substances) is a heterogeneous synthetic industrial chemical group that has been used since the 1950s which, due to its attractive properties, has a wide range of applications in our society. PFAS are persistent and bioaccumulative, which means that the levels increase in the environment over time; At higher levels, the substances are toxic and show a negative effect on human health.

    Sammanfattning : In Tanzania, approximately 76% of the drinking water supplies is dependent on groundwater sources. However, the groundwater in north Tanzania is susceptible to contamination by arsenic and fluoride. This study examines the spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, located in northern Tanzania. LÄS MER
