I have over 7 years experience with ICP-MS, ICP-OES, GFAA and FAA. I have worked with several universities in designing some real world experiments for undergrad students to carry out in the field of elemental analysis. I would suggest environmental toxicology, as these sample types are less dangerous than medical toxicology (Blood Borne Pathogens Issue).
I would say use the EPA Method for analysis of metals via ICP-OES in water, soil and sludge samples. I have several step by step SOPs for all of this, including sample prep, how to set up methods on the instrument and how to do the field sampling. The only real hazards would be the acids you need (HCL and HNO3) but these are both within OSHA regs for college level work, and do not pose much risk as long as the proper PPE is worn.
I am actually right in the middle of a project to get a Perkin Elmer Elan 9000 over at my undergrad school, so I am full throttle in this, so you have caught me at a good time if you want some really in depth info. One of the main projects that many undergrad schools do, is to take the students out into the field and collect water run off samples near landfills, and then test them for the EPA regulated elements to see how the concentrations look, and see whether or not anything toxic is leaching out of the waste in the landfills and out into the environment. You can then take all of the data and plug it into a stats analyzer like the program Minitab, or even Excel and see how the different collection points compare to each other. Then the students can write up reports outlining the process, the analysis as well as draw conclusions based on the data. It is a good experiment for undergrad students as it gives them some real world exposure into environmental toxicology, analytical chemistry and even regulatory compliance.
