The association between indoor smoke exposure due to traditional baking (baking homemade bread) and anthracosis has rarely been investigated. The aim of the present study is to quantify such association among the Iranian population. A hospital based case-control study was carried out on 83 anthracotic cases and 155 controls (83 individuals with non-anthracotic pulmonary disorders from the pulmo...

Auckland has a temperate climate with comfortable warm, dry summers and mild, wet winters. Auckland house design not only focus on winter thermal performance and indoor thermal condition, but also indoor moisture control, which is closely related to indirect health effects such as dust mites, fungi, etc. Most Auckland houses are designed to use temporary heating for winter indoor thermal comfor...

Protocol Summary The Michigan Department of Community Health (MDCH) and the Michigan Department of Environmental Quality (MDEQ) will conduct soil, indoor dust, and blood sampling for polychlorinated dioxins, furans, and coplanar PCBs. Based on the results of preliminary soil sampling in residential yards, 25 adults will be asked to participate in the Pilot Exposure Investigation. Participants w...

Exposure to house dust is a significant source of exposure to flame retardant chemicals (FRs), particularly in the US. Given the high exposure there is a need to understand the bioaccessibility of FRs from dust. In this study, Tenax beads (TA) encapsulated within a stainless steel insert were used as an adsorption sink to estimate the dynamic absorption of a suite of FRs commonly detected in in...

In this work, phthalic acid esters (PAEs): dimethyl phthalate (DMP), diethyl phthalate (DEP), di-n-butyl phthalate, benzyl butyl phthalate, bis(2-ethylhexyl) phthalate, and di-n-octyl phthalate in indoor dust (used as passive sampler) were investigated. The settled dust samples were collected from thirteen indoor environments from Palermo city. A fast and simple method using Soxhlet and GC-MS a...

A prevalence study was conducted among office workers in Malaysia (N= 695). The aim of this study was to examine associations between asthma, airway symptoms, rhinitis and house dust mites (HDM) and cat allergy and HDM levels in office dust. Medical data was collected by a questionnaire. Skin prick tests were performed for HDM allergens (Dermatophagoides pteronyssinus, Dermatophagoides farinae)...

Home characteristic questions are used in epidemiological studies and clinical settings to assess potentially harmful exposures in the home. The objective of this study was to determine whether questionnaire-reported home characteristics can predict directly measured pollutants. Sixty home inspections were conducted on a subsample of the 2006 population-based Toronto Child Health Evaluation Que...

Building associated illnesses - sick building syndrome (SBS) as a common example - are associated with staying in buildings with poor indoor air quality. The importance of indoor fungal growth in this phenomenon continues to be evident, even though no causative relation has been established so far. Indoor humidity is strongly associated with the symptoms of SBS. Fungal metabolites that may indu...

Greater attention is currently being paid to the relationship between indoor environment and childhood allergies, however, the lack of reliable data and the disparity among different areas hinders reliable assessment of the relationship. This study focuses on the effect of indoor pollution on Chinese schoolchildren and the relationship between specific household and health problems suffered. Th...

spreading wood particles and attached colored materials in work places can cause many problems for woodwork industry workers. the aim of this study is to design and implement a local exhaust ventilation system to control wood dust and isocyanates simultaneously. the study was conducted on 18 workers in the paint workroom of a wood door industry. at first, an overview of the workplace indoor air...
