Sampling and analysis techniques for inorganic air pollutants in indoor air

Effective evidence-based actions to reduce indoor air pollution must be derived from data obtained using accurate means for assessment of the critical pollutants and identification their sources. This is paramount importance provide robust evidence establishing effective policies or preventive measures. Nevertheless, designing a reliable sampling plan assessing concentration inorganic pollutant in requires expertise conducting rigorous campaigns proper knowledge on existing standards methodologies target substances. Therefore, this review focuses relevant information recommendations that should considered when collect complementary environment under study, properly define criteria details work ensure quality assessments. In particular, comprehensive most commonly used determination list monitoring has been compiled. Thus, gaseous such as CO2, CO, O3, NO2, NO, NH3, SO2, H2O2, H2S, HNO3 HNCO are included present review.
