Abstract The lack of data on the concentrations, sources and dynamics pollutants makes management household air quality ineffective. This PhD thesis focused identifying pollutant understanding factors influencing indoor concentration levels exposure in home. A survey 1698 urban 287 rural homes two one-week measurement campaigns showed that solid fuels, including charcoal, firewood sawdust, are ...

Few studies pay attention to the possible associations between indoor VOCs and childhood asthma in Shanghai considering effect of household ventilation. From March 2013 December 2014, we collected air samples from 358 children's bedrooms Shanghai, China. Information on asthma, environmental exposures, lifestyle behaviors was collected. Two-sample Mann-Whitney U test, bivariate logistic regressi...

Few empirical studies have examined the simultaneous effects of window opening and indoor plants on air characteristics. This study compared four variables, day/night, status, plant distance, number plants, characteristics in a room at basement via experiments. was because perform photosynthesis during day, which produces O2 absorbs CO2, whereas they usually produce only CO2 night. Moreover, hi...

IAQ is a crucial factor affecting the health, comfort, and productivity of workers, particularly those working in enclosed spaces like bank offices. This study aimed to evaluate office’s operational area vault by analyzing concentrations CO2, TVOC, PM10, PM2.5, as well temperature, relative humidity, air movement. Two different ventilation systems were compared assess their impact on IAQ. The a...

Elemental carbon (EC) content in air is considered a proxy for the diesel exhaust impact at workplaces. This paper examines possibility of estimating EC mine on basis measurements volatile organic compounds (VOC). The measurement study was carried out an underground metal mine. Gas chromatography with mass spectrometry (GC/MS) applied VOC determination, and thermal-optical analysis (TOA) FID de...

Multisensor information fusion technology is an advanced processing method that different from classical data technology. Capability and operational accuracy, in order to make effective comprehensive evaluation of environmental quality, the monitoring system built by NB-IoT sensor used conduct multisensor research on collected factors such as temperature, humidity, formaldehyde, PM2.5, TVOC. At...

Children spend a large amount of time in school environments and when Indoor Air Quality (IAQ) is poor, comfort, productivity and learning performances may be affected. The aim of the present study is to characterize IAQ in a primary school located in Taranto city (south of Italy). Because of the proximity of a large industrial complex to the urban settlement, this district is one of the areas ...

To discuss the reduction of formaldehyde and volatile organic compound (VOC) emissions from engineered flooring, cashew nut shell liquid (CNSL)-formaldehyde (CF) resin and CF/PVAc resin were applied for the maple face of the veneer bonding on plywood. The CF resin was used to replace urea-formaldehyde (UF) resin in the formaldehyde-based resin system in order to reduce formaldehyde and VOC emis...

To evaluate complaints of adverse reactions to marking pen emissions, groups of mice were exposed for 1 h to the emissions of 8 brands of felt-tip markers or white-board cleaner. Pneumotachographs and a computerized version of ASTM E-981 test method were used to measure changes in respiration. Sensory irritation (SI), pulmonary irritation (PI), and/or air flow limitation (AFL) of differing inte...
