In recent years field test kits have been largely used to identify arsenic (As) levels in contaminated water sources in Bangladesh, West Bengal (India), and elsewhere in the world to establish whether or not the water is safe. Most of the kits are based on the reaction of arsine gas with some chemical agent to form a coloured complex; the intensity of the colour is compared visually with a colour-coded chart or measured electronically to calculate the concentration of As in the water sample. In this paper, a step-wise review is presented of the analytical process used in the most commonly available As field test kits and the associated shortcomings of each of these kits. We also identify the research gaps for future work to enhance the accuracy and reliability of test results produced by these kits.
近年来，现场检测试剂盒在很大程度上已被用于识别孟加拉国、西孟加拉邦（印度）以及世界其他地方受污染水源中的砷（As）含量，以确定水是否安全。大多数试剂盒基于砷化氢气体与某种化学试剂的反应形成有色络合物；通过目视将颜色强度与颜色编码图表进行比较，或进行电子测量以计算水样中砷的浓度。本文对最常用的砷现场检测试剂盒所采用的分析过程及其各自相关的缺点进行了逐步回顾。我们还确定了未来工作的研究空白，以提高这些试剂盒所产生测试结果的准确性和可靠性。
