What is it about?

At the Nelson Mandela African Institution of Science and Technology, we analyzed water and wastewater samples from Themi River and the Arusha Waste Stabilization Pond (WSP) to find the levels of progesterone hormone. Although the levels of the endocrine disrupting chemical were not alarming, but progesterone was found to exist in high enough levels to cause harm to aquatic organisms.

Why is it important?

This is one of the few publications that have attempted to find endocrine disrupting chemicals (EDCs) in waters and wastewaters of a highly growing urban area in East Africa. It is a huge contribution to science from an area that has been highly understudied.


In my opinion, the information in this work is important as it sheds some light on the issues related to endocrine disrupting chemicals in sub-Saharan Africa. It forms a baseline for researchers who would like to study the distribution and levels of EDCs in the waters of suburban and urban Africa.
