9871241基尔达夫收购用于研究天然和环境工程系统中含水胶体和颗粒的仪器这是一项为仪器提供支持的建议，这些仪器将用于支持对水悬浮液中的胶体和颗粒在环境污染物的传输和去向中所起作用的研究。将重点研究影响饮用水质量、影响水处理过程的性能、有助于形成沉积物并控制其向环境释放污染物的胶体和颗粒，以及在生物、化学和地质过程的影响下影响碳和其他营养物质循环的胶体和颗粒。具体地说，这项研究将涉及有机胶体在形成致癌、致突变和有毒的消毒副产品中的作用；包括病毒、细菌和原生动物在内的微生物胶体对水质的影响；颗粒在沉积物形成和相关污染物释放中的作用以及在调节碳和其他营养物质的循环运动中的作用。该仪器将用于伦斯勒理工学院环境与能源工程系、生物学系和地球与环境科学系教职员工之间的合作研究，预计将帮助该学院发展强大的、多学科的研究重点，重点放在胶体和颗粒水成分上。

9871241 Kilduff ACQUISITION OF INSTRUMENTATION FOR RESEARCH ON AQUEOUS COLLOIDS AND PARTICLES IN NATURAL AND ENVIRONMENTALLY ENGINEERED SYSTEMS This is a proposal to provide support for instrumentation that will be utilized to support research on the role that colloids and particles in aqueous suspension play in transport and fate of environmental pollutants. Studies will be conducted that focus on colloids and particles that affect potable water quality, influence the performance of water treatment processes, contribute to the formation of sediments and control their release of contaminants to the environment, and that affect the cycling of carbon and other nutrients under the influence of biological, chemical and geologic processes. Specifically, the research will address the role of organic colloids in formation of carcinogenic, mutagenic and toxic disinfection byproducts; impact of microbial colloids including viruses, bacteria and protozoa on water quality; role of particles in formation of sediments and release of associated contaminants and in mediating the cyclic movement of carbon and other nutrients.The proposal leading to this award was submitted in response to the 1998 Major Research Instrumentation (MRI) Program Instrument Development and Acquisition Solicitation. The instrumentation will be used in research being conducted in a collaborative effort between and among faculty in Rensselaer Polytechnic Institute's Departments of Environmental and Energy Engineering, Biology, and Earth and Environmental Science and is expected to assist it in developing a strong, multidisciplinary research focus on colloidal and particulate aqueous constituents.
