Recently, indoor air quality has attracted the attention of policymakers and researchers as a critical issue like that of external air pollution. Indoor air quality is more important as people spend time longer indoors than outdoors. Indoor environments are closed compared to external environments providing less opportunity for the pollutants to dilute. The emissions contain many substances tha...

Air pollution is one of the greatest environmental risks to health, causing millions deaths and deleterious health effects worldwide, especially in urban areas where citizens are exposed high ambient levels pollutants, also influencing indoor air quality (IAQ). Many sources fairly obvious well known, but contribution outside still leads significant uncertainties, particular influence that varia...

Background: Cooking activities generate pollutants that can cause adverse health effects to occupants. This study aims characterize the indoor air environment in small and medium food enterprises (SMEs), as studies this area are scarce. Methods: A series of field measurements were conducted investigate IAQ at 14 SMEs selected Pulau Pinang for three different cooking methods (frying, boiling, ba...

According to UAE Health Ministry and Dubai Healthcare City reports, 15% of residents have a chronic respiratory disease such as asthma. Moreover, 90% the 150,000 patients at Al Ain Hospital suffered from upper tract diseases, bronchitis, or Sick Building Syndrome (SBS) has emerged social problem in United Arab Emirates (UAE). The Municipality regulates Indoor Air Quality (IAQ) with strict stipu...

Due to increasing health and environmental issues, indoor air quality (IAQ) has garnered much research attention with regard incorporating advanced clean technologies. Various physicochemical treatments have been used monitor, control, manage contaminants, such as monitoring devices (gas sensors internet of things-based systems), filtration (mechanical electrical), adsorption, UV disinfection, ...

The kindergarten’s indoor air contained a number of pollutants, including total volatile organic compounds, particulate matter, carbon monoxide and insufficient ventilation with high dioxide levels, which exceeded the quality (IAQ) guideline. presence these pollutants is caused by various factors inappropriate physical setting. Indisputably, authorities throughout countries provide guidelines f...

Abstract The presented paper deals with the assessment of selected indoor environmental quality (IEQ) factors, specifically parameters thermal comfort and air (IAQ), in two buildings a modern office complex. Both are LEED certified. monitoring IEQ risk factors took place spaces (cell open-space offices) representative all occupied areas under operating conditions. results real measurements IAQ ...

Children under 15 years spend over six hours per day in school buildings and are particularly vulnerable to the effects of poor indoor air quality (IAQ). However long-term monitoring environmental conditions is limited Australian schools. This study evaluates IAQ ten classrooms temperate settings Victoria. Temperature, relative humidity, CO2 concentration, PM2.5 PM10 were monitored a period one...

Humans spend the majority of their time indoors, where they are potentially exposed to hazardous pollutants. Within this context, over past few years, there has been an upsurge low-cost sensors (LCS) for measurement indoor air pollutants, motivated both by recent technological advances and increased awareness quality (IAQ) its potential negative health impacts. Although not meeting performance ...
