Dula Amarasiriwardena

Dula Amarasiriwardena, emeritus professor of chemistry, has a Ph.D. in analytical chemistry from North Carolina State University and his undergraduate work was completed at the University of Ceylon in Sri Lanka. He has a M.Phil. in chemistry from the University of Sri Lanka and a postgraduate diploma in international affairs from the Bandaranaiake Center for International Studies.

Professor Amarasiriwardena regularly teaches analytical chemistry, environmental chemistry and general chemistry. His research interests include topics in chemistry, environmental pollution, water quality, inductively coupled plasma-mass spectrometry, studies of trace metal analysis, toxic wastes, radon monitoring, pesticide residues, soil and environmental chemistry. This includes chemical speciation of arsenic and antimony and characterization of trace metals bound to soil-derived humic acids by size exclusion chromatography (SEC) or ion chromatography (IC) coupled with inductively coupled plasma-mass spectrometry (ICP-MS). He is also interested in the application of laser ablation (LA)-ICP-MS for investigation of past trace metal nutrition and the exposure to toxic metal pollutants using tissues such as human teeth and hair. He serves on the editorial boards of Environmental Pollution and Microchemical Journal. Professor Amarasiriwardena is a member of American Chemical Society, and Sigma Xi Honorary Research Society, and he served as the Chair of the Society for Applied Spectroscopy – New England Section. He has received grants from the National Science Foundation and the Pittsburgh Conference. Dula received the Gruber Award for Excellence in Students Advising at Hampshire College in 2014. He served as a Fulbright Specialist at the University of Concepción and University of Tarapaca in Chile. Professsor Amarasiriwardena is interested in chemical education, environmental issues in developing nations, and in activism in environmental groups through lobbying and education.

Recent and Upcoming Courses

Pollution and Our Environment
This course will explore environmental pollution problems covering four major areas: the atmosphere, the hydrosphere, the biosphere, and energy issues. Several topics, including acid rain; automobile emissions; ozone layer depletion; climate change; mercury, lead and cadmium poisoning; pesticides; solid waste disposal; and problems of noise and thermal pollution will be addressed. We will emphasize some of the environmental issues affecting our immediate community, as well as those in developing nations. We will also do several project-based labs, gain understanding of scientific methodology, and learn how to write scientific research reports. Class participation, satisfactory work on the required class projects, problem sets, literature critiques, and laboratory/field reports are required for evaluation. Keywords: pollution, environment, change, community, solid waste
Chemistry II
This is a continuation of Chemistry I: the principles and concepts examined during the previous term will be expanded and applied to more sophisticated systems. Topics will include chemical thermodynamics, nuclear chemistry, chemical equilibrium, acid-base equilibria and their applications, complex ion equilibria, and solubility, oxidation-reduction reactions, electrochemistry, and reaction rates. We will also emphasize application of those chemical principles to environmental, biological, industrial and day-to-day real-life situations. Problem sets will be assigned throughout the semester. The laboratory will consist of two project-based labs and some laboratory exercises. Basic laboratory skills, chemical instrumentation techniques, and the use of computers in the chemistry laboratory will be emphasized. Prerequisite: Successful completion of Chemistry I and its laboratory or instructor permission.
