砷是自然界中广泛存在的元素。此外,它可以在几种基质中发现不同的物种,因此它是化学形态中的目标元素之一。尽管陆生植物的研究数量很少,与鱼或尿液等基质相比,由于这种类型的基质与人类食物链密切相关,这一数字正在上升。在形态分析中,样品制备是一个关键步骤和几个提取程序存在的缺点。在这次审查中,处理提取程序的论文,分析方法,并严格讨论了在陆地环境中种植的植物中的物种保护研究。基于使用与HPLC-ICP-MS相关的水或稀酸溶液提取的分析程序是很好的替代方案。由于它们的多功能性和敏感性,尽管较便宜的策略被证明是可行的选择。
Arsenic is an element widely present in nature. Additionally, it may be found as different species in several matrices and therefore it is one of the target elements in chemical speciation. Although the number of studies in terrestrial plants is low, compared to matrices such as fish or urine, this number is raising due to the fact that this type of matrix are closely related to the human food chain. In speciation analysis, sample preparation is a critical step and several extraction procedures present drawbacks. In this
review, papers dealing with extraction procedures, analytical methods, and studies of species conservation in plants cultivated in terrestrial environment are critically discussed. Analytical procedures based on extractions using water or diluted acid solutions associated with HPLC-ICP-MS are good alternatives, owing to their versatility and sensitivity, even though less expensive strategies are shown as feasible choices.
