This project enables the implementation of modern environmental chemical analyses in the university's area of emphasis in environmental chemistry, which is offered as an option within the bachelor's chemistry degree program. The program's goal is to prepare students for careers in environmental monitoring, assessment, and industrial ecology research and development by teaching them U.S. Environmental Protection Agency (USEPA) methods of environmental analysis and assessment. This is done in two lecture/laboratory courses and a required independent research project. Students learn environmental assessment techniques by working as a group to prepare an Environmental Impact Statement (EIS) using National Environmental Policy Act (1970) guidelines. Samples are collected and analyzed to obtain data in support of the EIS. The only inorganic priority pollutant that had not been measured is Hg, and hence this project provides a vapor generator accessory to be used on an existing AAS. The project also provides a gas chromatograph mass spectrometer to enable measurement of specific organic compounds including chlorinated pesticides, PCBs, PAHs, and petroleum hydrocarbons. Other new equipment upgrades sample preparation procedures to improve safety, efficiency, and analyte yield and reduce the environmental impact of the analysis itself. This equipment includes a microwave-assisted digestor, a grinding mill, a tissue homogenizer, a freeze drier, a sonic dismembrator, solid-phase extraction units, and equipment to heat and recover solvents from Kuderna-Danish evaporators. The new laboratory experiences can be added to the university's Environmental Chemistry Laboratory manual, which is in use at other institutions. No other undergraduate teaching manual is available for teaching USEPA methods. The new equipment can also be used in mandatory student research projects, whose results are traditionally presented off campus. *

该项目使现代环境化学分析在大学的环境化学重点领域的实施，这是作为学士学位课程内的一个选项提供。 该计划的目标是通过教他们美国环境保护署（USEPA）的环境分析和评估方法，为学生在环境监测，评估和工业生态学研究和开发方面的职业生涯做好准备。 这是在两个讲座/实验室课程和所需的独立研究项目。 学生学习环境评估技术，作为一个小组工作，准备使用国家环境政策法（1970年）指导方针的环境影响报告书（EIS）。 收集和分析样品以获得支持环境影响报告书的数据。 唯一尚未测量的无机优先污染物是汞，因此本项目提供了一种蒸汽发生器配件，用于现有的原子吸收光谱仪。 该项目还提供了一个气相色谱质谱仪，以测量特定的有机化合物，包括氯化农药，多氯联苯，多环芳烃和石油烃。 其他新设备升级了样品制备程序，以提高安全性、效率和分析物产量，并减少分析本身对环境的影响。 该设备包括微波辅助蒸发器、研磨机、组织匀浆器、冷冻干燥器、声波破碎器、固相萃取装置以及加热和回收来自Kuderna-Danish蒸发器的溶剂的设备。 新的实验室经验可以添加到大学的环境化学实验室手册，这是在其他机构使用。 没有其他本科教学手册可用于教授美国环保局的方法。 新设备也可以用于强制性的学生研究项目，其结果传统上是在校外提出的。 *
