It has been found to be effective for removing heavy metals from both soil and water. This study focused on the fungal biosorption of specific heavy metals (Cd, Cr, Cu, As, Pb, and Zn) that are common environmental pollutants, as a means to bioremediate pollutants that can be consequences of rapid urbanization and industrialization. Fungal species were collected from contaminated sites along Waller Creek and their ability to biosorb heavy metals was investigated using ICPMS. Results found that Penicillium spp. from Waller Creek site CS was able to best biosorb Zn (110 g Zn/g fungal dry mass), while also performing well with Cr and Pb (4.6 and 4.0 g/g, respectively) and having detectable levels of As and Cd (0.3 and 0.2 g/g, respectively). Ag and Cu were only detected in single replicates, and so are not reliable datapoints. Limitations include bacterial contamination in original cultures from biomass suspensions, inconsistency in methodology as the procedure writing was an ongoing process and breaks within the fungi incubation process where culture conditions could not be checked on as frequently. Further investigation for other fungal species might be able to provide a deeper understanding on how different fungal characteristics affect their heavy metals bioremediation process and replications with varying concentration of heavy metals standard or performing more repeated runs on the ICPMS are suggested to reduce uncertainties in the data.Item Just What IS a Watershed?(0000-00-00) University of Texas at Austin; Environmental Science InstituteItem Let's Settle It(0000-00-00) University of Texas at Austin; Environmental Science InstituteItem Microbial Contaminants in Driking Water(0000-00-00) University of Texas at Austin; Ramirez, Roland; Environmental Science InstituteItem On the Surface(0000-00-00) University of Texas at Austin; Environmental Science InstituteItem The Ozone Layer, CFCs and Global Warming(0000-00-00) University of Texas at Austin; Environmental Science InstituteItem Solubility and Chemical Changes in Groundwater(0000-00-00) University of Texas at Austin; Gordon, J.D.; Environmental Science InstituteItem Use it Wisely(0000-00-00) University of Texas at Austin; Environmental Science InstituteItem Water - Is there going to be enough?(0000-00-00) University of Texas at Austin; Environmental Science InstituteItem Water - On the Surface and in the Ground(0000-00-00) University of Texas at Austin; Environmental Science InstituteItem Water - On the Surface and in the Ground (Highschool lesson)(0000-00-00) University of Texas at Austin; Environmental Science InstituteItem Water - Planning for the Future(0000-00-00) University of Texas at Austin; Environmental Science InstituteItem Water in the Texas Coastal Basin(0000-00-00) University of Texas at Austin; Environmental Science InstituteItem Water Usage and Conservation(0000-00-00) University of Texas at Austin; Environmental Science InstituteItem Watershed Model(0000-00-00) University of Texas at Austin; Environmental Science InstituteItem What Makes Up a Heatlthy Watershed?(0000-00-00) University of Texas at Austin; Environmental Science Institute
