采用该方案的学生将探讨污染物在水生，大气和陆地环境中的生物转化以及生态系统和人类健康所依赖的生物地球化学过程。重点是对环境污染和通过生物转化的物质循环问题进行现场和实验室实验以及预测建模的应用。
Students in this option address the biological transformations of contaminants in aquatic, atmospheric, and terrestrial environments and the biogeochemical processes upon which the health of ecosystems and humans depend. Emphasis is on the application of field and laboratory experimentation as well as predictive modeling to problems of environmental contamination and material cycling through biological transformations.
