The NATO SPS Workshop (unmapped: uri https://ephysimlab.usm.md/spsatcg5816/) on monitoring and protection of critical infrastructure by unmanned systems provided participants the opportunity to consider state-of-the-art ways of the use of Unmanned Vehicle Systems (UVS) and sensor network technology for threats monitoring of critical infrastructures. Also, sessions on the monitoring, data analysis and structural modelling, monitoring, and forecasting of natural catastrophes, as well as on the cybersecurity and protection of IT infrastructure were of special interests for students and experts working in the ICT field. We present a drone-based platform for the monitoring of air pollution with gaseous pollutants and solid microparticles, PM_2.5 and PM₁₀, as well as chemical and radiological contaminations. In addition, results on air pollution analysis for particulate matter including Atomic Force Microscopy (AFM) and Fluorescence Lifetime Imaging Microscopy (FLIM) are provided in this paper.
