Hi, my name is Dan Snow, and I’m a research associate professor in the School of Natural Resources and the Laboratory Services Director of the UNL Water Sciences Laboratory. I have been at UNL since 1990. I use analytical chemistry to help understand how water becomes contaminated and what we can do to prevent it. A good part of my work in the Water Sciences Laboratory involves creating analytical methods for new or "emerging" environmental contaminants like steroids, pharmaceuticals, algal toxins, explosives and pesticides. I also help develop methods to measure and use stable isotopes as tracers to study environmental problems and processes.
Mass spectrometry is an incredibly powerful tool to use in studying the occurrence and environmental fate of chemicals and their potential for affecting organisms and people. Students and staff I supervise use mass spectrometers to help other scientists and engineers find out exactly what chemicals are in water and other materials. I work with biologists studying endocrine disruption in fish in Nebraska rivers to find out what kinds and concentrations of steroid hormones and pesticides may be associated with these effects. I also work with scientists and engineers to find out what kinds and concentrations of steroid hormones and pharmaceuticals may be found in livestock and municipal waste, and whether or not these chemicals can get into water.

I give presentations about these chemicals and the way we measure them to students and other groups in classes, seminars and during tours of the Water Sciences Laboratory. I also assist agencies, educators, producers and the public with questions about water quality, water treatment and water testing. I have helped teach classes in environmental chemistry and plan to offer a class in how analytical chemistry is used to study water.
