Background: The European Commission has developed and put in place the Information Platform for Chemical Monitoring Data (IPCHEM), to promote a more coherent approach to the generation, collection, storage and use of chemical monitoring data in relation to humans and the environment.
Objectives: This paper describes the specific development of the IPCHEM thematic module "Products and Indoor Air Data" which aims to facilitate the retrieval of and access to existing and future chemical monitoring data sources stemming from e.g. national monitoring programs of EU Member States and EU funded projects. The current development focusses on harmonised data and metadata templates and code lists related to indoor air monitoring data.
Methods: The extension and revision of the IPCHEM metadata and data collection templates for indoor air monitoring data was based on harmonisation and standardisation efforts on the development of indoor air monitoring protocols and guidelines for monitoring indoor pollution attributed to chemical and biological stressors, which were undertaken by European Commission Services, EU funded projects and research networks and EU Members States.
Results: A list of ten candidate data collections for potential integration were identified and prioritised. A different level of relevance was attributed to the enhanced metadata and data elements (mandatory, recommended, optional) to allow for their flexible applicability by end users. These elements should be provided for reaching the required quality in the data documentation as well as for ensuring a correct data traceability and interpretation.
Conclusions: The proposed enhanced metadata and data models of the IPCHEM thematic module "Products and Indoor Air Data" can be used by data providers when planning and setting up their future indoor air monitoring campaigns, or to further mapping and harmonising data elements of their existing data collections for further integration into IPCHEM. This will boost the effective implementation of a coordinated approach for collecting, accessing and sharing existing and future indoor air monitoring data in support of policy making.

Commercial HVAC systems intended to mitigate indoor air pollution are operated based on standards that exclude aerosols with smaller diameters, such as ultrafine particles (UFPs, D ≤ 100 nm), which dominate a large proportion of indoor and outdoor number-based particle size distributions. UFPs generated from occupant activities or infiltrating from the outdoors can be recirculated and accumulate indoors when they are not successfully filtered by an air handling unit. Monitoring UFPs in real occupied environments is vital to understanding these source and mitigation dynamics, but capturing their rapid transience across multiple locations can be challenging due to high-cost instrumentation.

Wildfires at the wildland-urban interface (WUI) have been increasing in frequency over recent decades due to increased human development and shifting climatic patterns. The work presented here focuses on the impacts of a WUI fire on indoor air using field measurements of volatile organic compounds (VOCs) by Proton-Transfer-Reaction Time-of-Flight Mass Spectrometry (PTR-TOF-MS). We found a slow decrease in VOC mixing ratios over the course of roughly 5 weeks starting 10 days after the fire, and those levels decreased to ∼20% of the initial indoor value on average.

Formaldehyde (HCHO) has become a significant indoor air pollutant, arising from the widespread use of decorative and construction materials. Adsorption is the most convenient method for HCHO removal. However, the current adsorption is limited by the current low adsorption capacity and desorption.

Background: Coronavirus disease (COVID-19) quickly spread around the world after its initial identification in Wuhan, China in 2019 and became a global public health crisis. COVID-19 related hospitalizations and deaths as important disease outcomes have been investigated by many studies while less attention has been given to the relationship between these two outcomes at a public health unit level. In this study, we aim to establish the relationship of counts of deaths and hospitalizations caused by COVID-19 over time across 34 public health units in Ontario, Canada, taking demographic, geographic, socio-economic, and vaccination variables into account.

The national radon surveys in Montenegro revealed that the highest annual average radon concentrations (C) in ground floors of dwellings and schools were found in a rural region characterized as a typical high-karst area. In this region, spanning approximately 800 km, C values in 9 houses and 16 schools ranged from 219 to 2494 Bq/m, with AM = 977 Bq/m. To investigate the causes of these elevated indoor radon concentrations, the following parameters were measured near the 25 surveyed buildings: soil humidity, electrical conductivity, pH, activity concentrations of Ra, U, U, Th and K, radon concentration in soil gas (c), soil permeability for radon gas (k), and gamma dose rate in the air.
