WebTypes of VOCs The EPA categorizes VOCs by their volatility. 1. Very Volatile Organic Compounds (VVOC) boiling point range of <0 to 50-100 degrees centigrade Exist as gas. Ex: Propane Butane Methyl Chloride Types of VOCs The EPA categorizes VOCs by their volatility. 2. Volatile Organic Compounds (VOC) boiling point range of 50-100 to 240-260 ... WebNMVOCs include a large variety of chemically different compounds, such as benzene, ethanol, formaldehyde, cyclohexane, 1,1,1-trichloroethane and acetone. Essentially, … Concentrations of VOCs in indoor air may be 2 to 5 times greater than in outdoor air, sometimes far greater. During certain activities, indoor levels of VOCs may reach 1,000 times that of the outside air. Studies have shown that emissions of individual VOC species are not that high in an indoor environment, but the total concentration of all VOCs (TVOC) indoors can be up to five times higher than that of outdoor levels. New buildings experience particularly high levels of VOC off-… how many pounds is 7.5 kg
