NO This manual provides procedural guidance for monitoring total gaseous mercury in air using passive air samplers developed by a research institute, outlining device design, preparation, deployment, and post-exposure handling. It explains the sampler’s operation through diffusion and adsorption processes, highlighting features that enable both short- and long-term measurements and reduce contamination risks. The document details component materials, site selection criteria, environmental data recording, and installation requirements within a protective shelter. It further specifies exposure protocols, including handling of blanks, and concludes with instructions for sample retrieval, storage, documentation, and transport conditions to preserve sample integrity for subsequent laboratory analysis
