In the face of severe global epidemic, indoor architectural space has become one critical issues, and construction a new type “built environment” while solving “health epidemic prevention” goal active development in countries around world (SDGs & Pandemic Response); Pollutant concentration, optimization heat humidity environment, release environmental monitoring data, etc. It can not only p...

Around 50% of the world's population, particularly in developing countries, uses biomass as one of the most common fuels. Biomass combustion releases a considerable amount of various incomplete combustion products, including particulate matter (PM) and polycyclic aromatic hydrocarbons (PAHs). The paper presents the results of Indoor Air Quality (IAQ) measurements in six houses equipped with woo...

OBJECTIVES To investigate the association among symptoms of sick building syndrome (SBS). Self-reported questionnaire and indoor environmental surveys of newly build dwellings in Japan were conducted. MATERIALS AND METHODS The questionnaire included items on symptoms of SBS and lifestyle, and an indoor environmental survey (i.e., mold, mites, and volatile organic compounds (VOC)) was conducte...

In this study, 56 volatile organic compounds species (VOCs) and other pollutants (NO, NO2, SO2, O3, CO PM2.5) were measured in the northern suburbs of Nanjing from September 2014 to August 2015. The total compound (TVOC) concentrations higher autumn (40.6 ± 23.8 ppbv) winter (41.1 21.7 alkanes most abundant among VOCs (18.4 10.0 ppbv). According positive matrix factorization (PMF) model, found ...

Indoor air quality (IAQ) has become an important area of concern these days and tends to be more serious human health as well resident convenience, especially in smoke haze season (February - April) Upper Northern Thailand (UNT). monitoring model development for controlling the indoors is necessary all buildings, particularly urban areas polluted areas. This study aims i) indoor quality, ii) as...

As people spend 90% of their time indoors, it was necessary to improve indoor environmental quality enhance human productivity. Indoor consists air (IAQ), thermal, visual, and acoustic comfort. However, only a few studies have investigated the combined effects IAQ noise. During after COVID-19 pandemic, portable cleaner is often used in buildings reduce concentration particles air, but also gene...

One of the main preventive measures recognized by WHO and implemented to mitigate COVID-19 epidemic impact, controlling transmission coronavirus, was use a facemask. Since facemask is an accessory that can be used several hours day, through which air we breathe passes, in contact with face skin, it must not cause discomfort wearer contain toxic, irritating or sensitizing substances. Therefore, ...

This paper presents results of a comprehensive survey conducted to better understand concentrations and spatial variations of indoor and outdoor concentrations of volatile organic compounds (VOCs) in industrial, urban and suburban neighborhoods. Three cities, representing these types of neighborhoods in Michigan, USA were selected, and 30 to 50 homes were selected in each city. Duplicate or tri...

asthma and atopic dermatitis are common allergic diseases, and their prevalence has increased in urban children. recently, it is becoming understood that forest environment has favorable health effects in patients with chronic diseases. to investigate favorable clinical and immunologic effects of forest, we examined changes in clinical symptoms, indirect airway inflammatory marker, and serum ch...

BACKGROUND Construction painters have not been studied well in terms of their hazards exposure. The objective of this study was to evaluate the exposure levels of total volatile organic compounds (TVOCs) for painters in the construction industry. METHODS Activity-specific personal air samplings were carried out in three waterproofing activities [polyurethane (PU), asphalt, and cement mortar] ...
