• Increased use of pharmaceuticals such as antibiotics has lead to the presence of biologically active antibiotics (i.e ampicillin) in surface waters, causing awareness of possible human and environmental health concerns. These non-target effects could cause effects on aquatic ecosystems and ecological communities. One of the main components of an aquatic ecosystem is their microalgae communities which are the main primary producers for aquatic ecosystems.
  Microalgae species and communities could be affected by antibiotic presence in the water bodies leading to possible shifts of populations in the communities. Using Pseudokirchneriella subcapitata, Chlorella spp., and Scenedesmus spp. an acute 72hr growth inhibition test was performed on three individual species, and as a community. Toxicity was assessed by measuring absorbance at 415nm to find algae density changes and by observing population changes in
  different concentrations of ampicillin.
