Abdullah Alowaifeer, graduate student, will present "Bioaccumulation of arsenic and mercury" as part of the LRES Seminar Series in 346 Leon Johnson Hall.
Arsenic and mercury are found in aquatic environments worldwide. Fish and fish products consumption constitutes one of the primary sources of human exposure for both. Upon prolonged exposure to these metal(loid)s, serious health effects can result and thus it is critical that we understand how each enters and accumulates in food chains and thus in human endpoints. My PhD work consists primarily of two research thrusts. The first examines food chain arsenic and mercury accumulation in a natural aquatic ecosystem, Yellowstone Lake. The second concerns understanding the biochemical basis for arsenic bioaccumulation in bacteria, using the bacterium Agrobacterium tumefaciens as a study model.
