项目摘要

The equipment requested is an Atomic Absorption Spectrophotometer (AA) with the capability of measuring cations in a number of environmental matrices via either flame or graphite furnace. This equipment is a replacement for an existing machine that has proven to be an essential component in fundamental and applied research programs in environmental physiology and toxicology. The AA will support two successful multidisciplinary research groups who study the interplay between the environment (biotic factors such as species-interactions, and physicochemical factors such as salinity, oxygen, temperature, pH, ammonia, toxicants) and the responses of the individual animal and the ecosystem to that environment. Specifically, this equipment will aid in examining the effects of municipal and industrial effluents, nanomaterials, sediments, pesticides and hydraulic fracturing fluids on the environment, and the fish and invertebrates therein. The AA will be used to measure cations including, but not restricted to sodium, calcium and potassium. and contaminating heavy metals such as cerium, silver, nickel, copper and cadmium. These will be measured in water samples, and in animal tissues (e.g. plasma). This instrumentation will provide an excellent training environment for numerous undergraduate and graduate students and help in improving environmental sustainability in Canada.

所需的设备是原子吸收分光光度计 (AA)，能够通过火焰或石墨炉测量许多环境基质中的阳离子。该设备是现有机器的替代品，已被证明是环境生理学和毒理学基础和应用研究项目的重要组成部分。 AA 将支持两个成功的多学科研究小组，研究环境（物种相互作用等生物因素，以及盐度、氧气、温度、pH 值、氨、毒物等物理化学因素）与个体动物和动物的反应之间的相互作用。生态系统到该环境。具体来说，该设备将有助于检查城市和工业废水、纳米材料、沉积物、杀虫剂和水力压裂液对环境以及其中的鱼类和无脊椎动物的影响。 AA 将用于测量阳离子，包括但不限于钠、钙和钾。并污染重金属，如铈、银、镍、铜和镉。这些将在水样和动物组织（例如血浆）中进行测量。该仪器将为众多本科生和研究生提供良好的培训环境，并有助于改善加拿大的环境可持续性。
