A review on inorganic gaseous pollutants in conservation spaces: monitoring instrumentation and indoor concentrations

This contribution presents the results of a review of scientific literature on gaseous inorganic pollutants monitored in confined indoor spaces housing cultural heritage. A survey on standards suggesting concentration thresholds together with European projects on the topic was provided. Sixty-six scientific articles were systematically selected based on the PRISMA flow diagram over the period 1984–2021 for a total number of 80 case studies mainly located in Europe (64
