Seasonal cycle of indoor-VOCs: comparison of apartments and cities

Mapping Cumulative Environmental Risks: Examples from the EU NoMiracle Project

“…A comparable seasonal cycle of concentrations was observed by Schlink et al [44] for indoor volatile organic compounds.…”

VOCs Levels in Indoor and Outdoor Residential Homes in Helwan, Egypt

“…Indoor concentrations are also affected by climatic conditions and air exchange rate due to forced or natural ventilation (4) . This recorded concentration is about twice the median concentration of VOCs measured by Maisey (49) in Western Australia (38.1 µg/m 3 ); about three times the maximum TVOCs in indoor 0.5-22.4 µg/m 3 recorded by Sexton (50) and more than 0.31-28; 1.39-13.91 and 0.5-58.6 µg/m 3 measured by Gustafson; Kuntasal and Schlink, respectively (51)(52)(53) .…”

Comparative study of indoor-outdoor exposure against volatile organic compounds in South and Middle America

“…Since most people spend over 80 percent of their time indoors [10], indoor VOCs are thought to be of greater concern considering potential health effects because the indoor concentrations of these compounds are often higher than those typically encountered outdoors. On the one hand the indoor-outdoor ratio (I/O) is generally used to infer penetration to indoor environments and indoor sources [18].…”

“…The occurrence and concentrations of VOCs in residences can be affected by outdoor atmospheric conditions, indoor sources, indoor volume, human activities, chemical reactions, ventilation rates, and seasonal factors [9,10].…”
