Background and Objective: The presence of fungal bioaerosols in hospitals indoor environments have affected the health of patients with the defect in immunity system. Therefore, determination of the rate and species of these agents is essential. This study aimed to investigate association between fungi contamination and particulate matter (PM10, PM2.5 and PM1) concentrations in the main indoor ...
The research literature provides strong evidence that characteristics of buildings and their indoor environments influence the prevalence of several adverse health effects. Kuwait is considered one of the countries with harshest weather conditions. It is estimated that Kuwaitis spend most of their times indoors. Indoor environments quality should be taken seriously since indoor allergens and ir...
This study was carried out to determine the distribution of particles in classrooms in primary schools located in the centre of the city of Sari, Iran and identify the relationship between indoor classroom particle levels and outdoor PM2.5 concentrations. Outdoor PM2.5 and indoor PM1, PM2.5, and PM10 were monitored using a real-time Micro Dust Pro monitor and a GRIMM monitor, respectively. Both...
In this study, polyhalogenated compounds such as BFRs were analyzed in indoor air and dust samples from two homes in Japan. Concentrations of PCBs and TBPs in exhaust and indoor air of two houses were detected at 10 – 10 pg/m orders and were well above those in outdoor air. For dust samples, the detected PBDE and PBDD/F concentrations were in the range of our past study. Interestingly, compared...
BACKGROUND Previous research has found relationships between specific indoor environmental exposures and exacerbation of asthma. OBJECTIVES In this review we provide an updated summary of knowledge from the scientific literature on indoor exposures and exacerbation of asthma. METHODS Peer-reviewed articles published from 2000 to 2013 on indoor exposures and exacerbation of asthma were ident...
Introduction We are exposed to brominated flame retardants (BFRs) in daily life through multiple media including food products, air, and dusts; direct exposure to BFRs from treated goods is also of considerable importance. However, very little is known about behavior of BFRs in the consumer products. Since textile products such as curtains, carpet, and seat covers have high specific surface are...
Adverse health and environmental effects of household dust are derived from their chemical composition and properties. In this study, household, stairs and entryway dust (<20 μm) samples from homes located in urban, residential and residential near to industrial area in Greater Cairo during summer 2013 were collected to study their chemical composition, characterization and factors affecting th...
Background: The climate change and particulate matter emission contented of bioaerosols is known as an important reason of increasing the allergic interactions especially in patients with defect in immunity system. The aim of this study was to investigate fungal bioaerosol concentrations in relation to particulate matter (PM10, PM2.5 and PM1) in indoor parts and ambient air of the generd educat...
