Recent advances in miniaturization of chemical instrumentation and in low-cost small drones are catalyzing exponential growth in the use of such platforms for environmental chemical sensing applications. The versatility of chemically sensitive drones is reflected by their rapid adoption in scientific, industrial, and regulatory domains, such as in atmospheric research studies, industrial emission monitoring, and in enforcement of environmental regulations. As a result of this interdisciplinarity, progress to date has been reported across a broad spread of scientific and non-scientific databases, including scientific journals, press releases, company websites, and field reports. The aim of this paper is to assemble all of these pieces of information into a comprehensive, structured and updated review of the field of chemical sensing using small drones. We exhaustively review current and emerging applications of this technology, as well as sensing platforms and algorithms developed by research groups and companies for tasks such as gas concentration mapping, source localization, and flux estimation. We conclude with a discussion of the most pressing technological and regulatory limitations in current practice, and how these could be addressed by future research.
微型化学仪器和低成本小型无人机的最新进展正在推动这些平台在环境化学传感应用中的使用呈指数级增长。化学敏感无人机的多功能性反映在它们在科学、工业和监管领域的快速采用，例如在大气研究、工业排放监测以及环境法规的执行中。由于这种跨学科性，迄今为止的进展已经在广泛的科学和非科学数据库中得到报道，包括科学期刊、新闻稿、公司网站和现场报告。本文的目的是将所有这些信息整合到一个关于使用小型无人机进行化学传感的全面、结构化和更新的综述中。我们详尽地回顾了这项技术的当前和新兴应用，以及研究小组和公司为气体浓度测绘、源定位和通量估计等任务开发的传感平台和算法。最后，我们讨论了当前实践中最紧迫的技术和监管限制，以及未来研究如何解决这些问题。
