Spring 2005.

Apart from some minor editing to produce a reasonably uniform title and abstract page, I have not made any editorial changes to these reports; they are how the undergraduate students produced them at the end of the semester. In most cases, the graduate student associated with the project did not have an opportunity to offer suggestions for changes. The guidelines that the students were given regarding the report for this semester can be found elsewhere on the site. The students did have access to the reports from the fall of 2004, if they chose to look. There are some problems with these reports, so they should not be considered as models. Students were not asked specifically to document how the report was produced, but some did indicate (in their report of who did what in each group) that in some groups each student took responsibility for a particular section. This mode of operation was confirmed by the gradatue students with whom I met on June 13th 2005 for a discussion of the semester's activities.

The project titles are:

1. Arsenic Contamination: Do vegetables planted in arsenic-contaminated soil take up dangerous amounts of arsenic? Do vegetables planted close to pressure-treated wood structures take up dangerous amounts of arsenic? Do certain vegetables take up more arsenic than others?

2. Removal of Arsenic (III) from waters by using iron filings

3. The Determination of Arsenic in Pressure Treated Wood on the Umass Campus

4. Total Arsenic Determination of Soils in Areas Proximal to Sources of Contamination

5. Microbial Volatilization of Arsenic

6. Analysis of inorganic arsenic in surface water and sediment in Amherst Massachusetts using hydride generation inline with inductively coupled plasma- atomic emission spectrometry

7. Modifying the Arsenic Test Kit: Adjusting the Number of Times Swirled During the 30-minute Reaction Period and Changing Temperature

8. Arsenic Removal using bread mold and sources of Acidophilus Lactobacillus

9. Removal of Arsenic from Contaminated Water with Zinc-Sulfide

10. Measurement of Arsenic in the Soil of University of Massachusetts Amherst Campus
