项目摘要
Although the element iron (Fe) is the most abundant transition metal in atmospheric aerosols, it can be a limiting nutrient in large areas of the surface ocean. The availability of Fe as a biological nutrient depends on its particle size, solubility and chemical speciation, all of which are source dependent.The set of questions presented in the proposal are focused on the physiochemical production and measurement of atmospheric soluble Fe (Fesol), forms. In particular, these studies will be directed towards the valuation of soluble Fe emitted by automobile vehicle exhaust. As well as comparing the total Fe (Fesol) associated with combustion from different motor vehicle types (e.g. gasoline, diesel and compressed natural gas fuels) under well characterized (chassis dynamometer) driving conditions, an effort will be made to characterize the quantity of fuel borne Fe. A second part of the project will look at the speciation of solubilized Fe that result from the dissolution by polycyclic aromatic hydrocarbons, both a fraction of common hydrocarbon fuels and a combustion fuel by product.
虽然铁元素(Fe)是大气气溶胶中最丰富的过渡金属,但在海洋表面的大片地区,它可能是一种有限的营养物质。铁作为生物营养物的有效性取决于其粒度、溶解度和化学形态,所有这些都依赖于来源。提案中提出的一系列问题集中在大气可溶性铁(Fesol)形式的物理化学生产和测量上。特别是,这些研究将针对汽车尾气排放的可溶性铁的估值。除了比较不同机动车辆类型(如汽油、柴油和压缩天然气燃料)在良好表征(底盘测力仪)驾驶条件下与燃烧相关的总铁(Fesol)外,还将努力表征燃料携带铁的数量。该项目的第二部分将研究由多环芳烃溶解产生的可溶性铁的形态,多环芳烃是普通碳氢化合物燃料的一部分,也是燃烧燃料的副产品。
