The researchers examined the potential ecological impacts of pharmaceuticals and personal care products (PPCPs) by focusing on triclosan, an antibacterial compound whose use has dramatically increased in recent years. The project addressed three main questions: (1) Are there detectable levels of triclosan in waters and sediments of Illinois rivers and streams? (2) Are the levels of triclosan in Illinois rivers and streams impacting the resident bacterial communities? (3) How does triclosan impact the composition and function of sediment bacterial communities? These questions were studied using a combination of field surveys and experimental work in laboratory-scale model streams. The results and conclusions of this project will be discussed during the seminar.
