Wooden Structures

Construction materials containing tar products are a source of indoor air pollution in buildings. This particularly concerns old buildings, in which wooden structures were impregnated with tar compositions (creosote oil and Xylamite oil containing tar products) and buildings in which bituminous seal containing hydrocarbon solvents was used. During the 1970s and 1980s, an impregnant known as Xylamite was commonly used in Polish buildings. This material still emits organic vapors into the building’s environment, significantly worsening indoor air quality (IAQ). Xylamites and other impregnating materials are a source of indoor air pollution through toxic organic compounds, such as phenol, cresols, naphthalenes, chlorophenols (CPs), and chloronaphthalenes (CNs), which emit specific odors. TD-GC/MS enables detailed identification of the reasons behind chemical indoor air pollution. The results of laboratory tests on the chemical emissions of bitumen-impregnated materials were presented in 32 case studies. In turn, the results of indoor air pollution by volatile bitumen components were presented on 11 reference rooms and 14 case studies, including residential buildings, office buildings, and others. Laboratory tests of samples of construction products confirmed the main emission sources into indoor air. The research results for the period 2014–2019 are tabulated and described in detail in this manuscript.

Indoor air pollution level in dwellings varies in different areas. Specifically, the formaldehyde and total volatile organic compound pollution are serious in new residential buildings according to the investigation of indoor air pollution status of residential buildings in China. Appropriate ventilation, as an important means to reduce the concentration of indoor pollutants, is mainly affected by ventilation mode, ventilation performance, ventilation strategies, etc. This paper analyses the status, standards, technologies and products related to residential ventilation and concludes the existing drawbacks in residential ventilation applications in China. Understanding of residential ventilation, and its standards, design methods, technologies, products, also the economy and usability should be given a major consideration to research.

AbstractMuch of the population in developing countries uses firewood for cooking. The resulting indoor air pollution has severe health consequences for children who are close to the fire while their mothers cook. We use survey data from Guatemala to examine the effects of firewood consumption on the health of children up to five years of age. We also investigate the impact of cooking inside the home, the importance of a mother cooking while caring for her children and the role played by the smoke permeability of housing construction materials. We find that children living in households that use more wood, and where exposure to indoor air pollution is higher because the mother cooks while caring for children or because cooking takes place inside, are more likely to have symptoms of respiratory infection. Simulations indicate that policies that target cooking habits in order to directly reduce exposure, particularly by reducing the number of women who simultaneously cook and care for children, may be more effective for improving young children's health than policies to accelerate the adoption of gas stoves.

AbstractIndoor air pollutant is a serious problem due to its wide diversity and variability. The harmful substances from construction materials and decorative materials may make the indoor air pollution become more and more serious and cause serious health problems. In this paper, the review summarizes the advanced technologies for the removal of indoor air pollutants and the development in the treatment of indoor air pollution by catalytic oxidation technologies. Meanwhile, some catalytic oxidation mechanisms of indoor air pollutants are proposed in detail, and suggestions for the indoor air pollution treatment are also presented, in order to provide some reference for subsequent research.

Background: Indoor air pollutants are increasingly being associated with respiratory illnesses leading to high degree of morbidity and mortality. There are not sufficient epidemiological studies from Pakistan which assess level of awareness of indoor air pollution resulting in respiratory diseases in population. Methods: This cross sectional survey was carried out on general population of Rawalpindi/Islamabad. Sample size was 223 study subjects selected by non-probability convenient sampling. Knowledge of the study subjects was determined with regard to indoor air pollution, its effects on health and different sources of indoor air pollution with the help of a questionnaire. The influence of age, gender, educational status and socio economic status on the level of awareness was also analyzed. Results: Out of total 223 participants, 115 were males and108 females. Participants aware of indoor air pollution were 91.5% and adequate awareness about its sources was 80.7%. Those who knew indoor air pollution is detrimental to health were 95.1%. Awareness about building construction dust as source of indoor air pollution was maximum (84.8%). There was significant difference in awareness among participants with different monthly incomes and educational status and also between males and females. Conclusion: This study concludes that general population of Rawalpindi/Islamabad has fairly good awareness about sources of indoor air pollution. Use of harmful material causing indoor air pollution should be limited or substituted with better ones where possible.
