Indoor air quality (IAQ) in nursery school is believed to be different from elementary school. Moreover, younger children are more vulnerable to air pollution than higher grade children because they spend more time indoors, and their immune systems and bodies are less mature. The purpose of this study was to compare the concentrations of the monoaromatic volatile benzene, toluene, ethylbenzene ...

We reviewed the literature on Indoor Air Quality (IAQ), ventilation, and building-related health problems in schools and identified commonly reported building-related health symptoms involving schools until 1999. We collected existing data on ventilation rates, carbon dioxide (CO2) concentrations and symptom-relevant indoor air contaminants, and evaluated information on causal relationships bet...

Activated carbon (AC) has been widely used in indoor air quality (IAQ) control for removal of hazardous volatile organic compounds (VOCs). A detrimental effect of this adsorption technology is that bacteria multiplied on AC may deteriorate IAQ. In this paper, antibacterial AC nanocomposites with welldispersed silver nanoparticles (Ag/ACs) were prepared by the attachment of Agþ on the functional...

Indoor air quality (IAQ) influences individual physical and mental health. Laboratory studies conducted in environmental chambers have shown that IAQ parameters such as temperature, humidity, CO 2 , volatile organic compounds (VOCs) may impact participants’ productivity cognitive performance. To better understand the influence of VOC at low concentration on function, this study applied a contro...

The study investigated the concentration and distribution features of culturable airborne fungi (CAF) in indoor air for four public transport vehicles (bus, metro, metrobus, ferry) Istanbul. collection samples was performed from each vehicle both directions once a month March 2017 to February 2018. highest lowest CAF concentrations measured during were determined be 40–660 CFU/m3 bus, 20–400 40...

UNLABELLED This study, a randomized controlled trial, evaluated the effectiveness of free-standing air filters and window air conditioners (ACs) in 126 low-income households of children with asthma. Households were randomized into a control group, a group receiving a free-standing HEPA filter placed in the child's sleeping area, and a group receiving the filter and a window-mounted AC. Indoor a...

Introduction: Mold may affect the Indoor Air Quality (IAQ) in workplace dormitories. This study aims to investigate indoor air factors that molds growth a dormitory of an LNG Company Indonesia. Several determinant factors, including relative humidity, general temperature, wet dry velocity, illumination, particulate matter, and carbon dioxide concentration were assessed against microorganism col...
