Amid growing concerns over Indoor Air Quality (IAQ), this paper presents a comprehensive analysis of pollutants to assess the environmental health in few Case Study Buildings (CSBs). The main objectives were evaluate levels key Pollutants (IAPs) (PM10, PM2.5, CO, CO2, TVOCs) and relative humidity across multiple social housing properties analyze how occupant behaviormay affect IAQ. Utilizing quantitative measurements, study investigates range exposure building occupants IAPs. methodology involves systematic measurement IAPs through installation data loggers, focusing on pollutant air quality CSBs. Findings show fluctuation levels, with some demonstrating consistently within acceptable while others exhibit sporadic spikes concentrations. results indicate that significant attention should be given PM10, VOCs. This underscores importance continuous monitoring targeted interventions mitigate poor IAQ ensure healthier indoor environments for occupants. Further research implementation effective measures are imperative safeguard public well-being.

Buildings are constructed and operated to satisfy human needs improve quality of life. Good indoor air (IAQ) thermal comfort prerequisites for health well-being. For their provision, buildings often rely on heating, ventilation, conditioning (HVAC) systems, which may lead higher energy consumption. This directly impacts efficiency goals the linked climate change considerations. The balance between use, optimum IAQ calls scientifically solid well-established limit values exposures experienced by building occupants in spaces, including homes, schools, offices. present paper aims appraise selected pollutants reported scientific literature, how they handled international national guidelines standards. include carbon dioxide (CO2), formaldehyde (CH2O), particulate matter (PM), nitrogen (NO2), monoxide (CO), radon (Rn). Furthermore, acknowledging particularly strong impact use from HVAC, temperature (T), relative humidity (RH) also included, as relate both possibilities avoid moisture related problems, such mould growth proliferation house dust mites.

Lung inflammatory disorders are a major global health burden, impacting millions of people and raising rates morbidity death across many demographic groups. An industrial chemical common environmental contaminant, formaldehyde (FA) presents serious concerns to the respiratory system, including onset aggravation lung disorders. Epidemiological studies have shown significant associations between FA exposure levels incidence severity several diseases. causes inflammation in tract via immunological activation, oxidative stress, airway remodelling, aggravating pre-existing pulmonary compromising function. Additionally, functions as sensitizer, causing allergic responses hypersensitivity pneumonitis sensitive people. Understanding complicated processes behind formaldehyde-induced is critical for directing targeted strategies aimed at minimizing exposures alleviating burden formaldehyde-related illnesses on health. This abstract explores intricate relationship diseases, asthma, bronchitis, inflammation, injury fibrosis.

Indoor air in residential dwellings can contain a variety of chemicals, sometimes present at concentrations or combinations which have negative impact on human health. Air Quality (IAQ) surveys are often required to characterize exposure investigate IAQ concerns and complaints. Such should include sufficient contextual information elucidate sources, pathways, the magnitude exposures. The aim this review was describe parameters that affect dwellings: building location, layout, ventilation, finishing materials, occupant activities, demography. About 180 peer-reviewed articles, published from 01/2013 09/2021 (plus some important earlier publications), were reviewed. importance largely depends study objectives whether focus is specific pollutant assess health risk. When considering classical pollutants such as particulate matter (PM) volatile organic compounds (VOCs), significant IAQ, detailed these needs be reported each study. Research gaps suggestions for future studies together with recommendation where measurements done also provided.

This paper reports on the findings from INDAIRPOLLNET (INDoor AIR POLLution NETwork), a recently completed European COST Action network. ran September 2018 to March 2023 with more than 200 indoor and outdoor air quality scientists universities, large small companies, research institutes around Europe beyond. The expertise of our interdisciplinary network members covered chemistry, biology, standardisation, household energy, particulate matter characterisation, toxicology, exposure assessment, cleaning, building materials, physics engineering (including ventilation energy), design. aim was design framework for future chemistry field campaigns, improved understanding chemistry. main focus better understand sources, transformations fate chemical pollutants found in buildings. In this paper, we present network, which include call greater spatial temporal coverage measurements indoors, need standardised techniques impact occupants quality. We also checklist parameters that should be measured any campaign. Finally, new framework, focusing 5 key areas: reactivity environments; mapping organic constituents indoors; role occupant chemistry; modelling studies novel materials technologies indoors. hope will use community, enabling healthier buildings future.

This study examines impacts typical Indian cooking practices on indoor air quality characteristics by monitoring evolution fine ultrafine particle (UFP) concentration dining facility residential educational institute India. The area was spread across kitchen (zone1) hall (zone2). A combination validated low-cost PM sensors (LCS), DustTrak8433, Scanning Mobility Particle Sizer (SMPS) utilized for real-time data acquisition while using Liquefied Petroleum Gas (LPG) fuel. PM2.5 UFP concentrations were monitored at 1.3 m 1.8 from floor assess vertical variation pollutants during activities, including breakfast, lunch, dinner, processes such preheating, reheating, stir-frying, deep-frying. It found that prolonged durations involved high-heat methods like stir-frying deep-frying resulted rise coarser (300-550 nm) PM2.5, causing higher exposure concentration. levels are upper heights because temperature-driven convection currents hygroscopic growth particles due high humidity levels. Air exchange rates (AER) considerably varied chimneys low controlled (closed doors) compared mixed ventilation (opened conditions. maximum AER obtained lunch (4.3 9.9 h-1) breakfast (-7.8 6.8 dinner (0.55 7.9 h-1). decrement rate inside zone 1 highest (126µgm-3h-1), coinciding with ventilation. recommended improving better design can reduce commercial rural kitchens.
