Atomic Absorption and Graphite Furnace for Environmental Physiology and Toxicology

要求的设备是原子吸收分光光度计（AA），具有通过火焰或石墨炉测量多种环境基质中的阳离子的能力。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，他们研究环境之间的相互作用（生物因素，如物种相互作用，物理化学因素，如盐度、氧气、温度、pH值、氨、毒物）以及个体动物和生态系统对环境的反应。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、农药和水力压裂液对环境的影响，以及其中的鱼类和无脊椎动物。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（如血浆）中测量。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。

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.
