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-… Witryna2), other non-methane compounds, and traces of VOCs from previous cargo. During loading, hydrocarbon gases (methane–pentane and heavier components) are also released from the cargo. The release of these compounds, combined with the rising cargo level, results in a pressure increase of the cargo tank that is eventually vented …
