We will begin by discussing what volatile organic compounds are, before asking how they contribute to poor indoor air quality. Finally, we will outline a number of ways in which to control and minimise their presence in residential environments. What are VOCS and how do they contribute to poor...
Environmental Protection Agency, volatile organic compounds (VOCs) are pollutants that permeate the air as gases from certain solids or liquids. Substantial VOC content in products is, of course, a bad thing from both an environmental and health standpoint; but when it comes to indoor air quality...
While natural ventilation remains the most efficient means to decrease indoor VOC levels, air purifiers have gained popularity to sustain indoor air quality, particularly under challenging outdoor conditions, such as elevated fine dust concentrations, heat waves, and extreme cold. Typically, air purifier...
the air quality guidelines for specific substances,while they do not refer to specific environmental settings,may be difficult to apply to the indoor environment.for example,the relevant compounds often occur in mixtures at higher concentrations indoors than they do in outdoor air,thus providing multi...
If you are concerned about Volatile Organic Compounds, and the effect they can have on your indoor air quality and health, it is important to speak to an expert. Our local specialists can conduct a free home survey to assess the level of ventilation in your home and provide advice about th...
Any organic compound that evaporates at room temperature and is hazardous to human health, causing poor indoor air quality. Many VOCs found in homes, such as paint strippers and wood preservatives, contribute to sick building syndrome because of their high vapor pressure. VOCs are often used in ...
In recent years proof of "indoor air quality", designed to protect and improve the health and safety of workers, was a central strategy in the prevention of many companies. The man creates with the environment in which he lives and works a continuous gas exchange through breathing; this ...
VOCs generated from construction materials, furniture, and household essentials are considered as the main causative substances of so-called "Sick building syndrome", a typical indoor health problems. In 2002, Ministry of Health, Labour and Welfare of Japan formulated the indoor air quality guideline...
