The purpose of this article is to provide the reader with factual information to demonstrate that the use of MDI compared to other agents used in CWP production processes does not pose increased inhalation exposure risks for workers.
Increasing inhalation of ambient ultrafine particles has been linked with exacerbation of respiratory symptoms and mortality among COPD sufferers [16], [17], [18].
Second, it could increase the effect of PM10 through increased inhalation during the activities outside (e.g., exercise), which also could increase the effect of O3.
[ 5] For example, patients who hyperventilate during a panic attack, can develop increased bronchospasm as a result of increased inhalation of cold and dry air.
They indicate that the trend for increased dermal uptake with increasing age is significant for DEP and DnBP, whereas the trend for increased inhalation uptake is significant for DnBP, but not DEP.
Increased activity level increases inhalation rate up to severalfold, and those with higher activity levels in relation to work or recreation outdoors will receive a higher effective dose of pollution, particularly on days when outdoor air quality is poor.
Elsewhere we show that EC children have blood enriched with lower-molecular weight PCBs relative to other congeners, a finding that may denote increased inhalation exposure for this demographic.
In aggregate across all trips, the benefit from the averted exposure to PM2.5 in the underground approximately balanced the harms from increased inhalation of pollutants as a result of the higher ventilation rates associated with cycling.
Davis et al. [ 22] showed several plasma immune mediators were associated with increased inhalation injury severity, even after adjusting for age and percentage of total body surface area burned.
Outdoor walking and cycling spaces often have lower concentrations of traffic-related pollutants than in-vehicle spaces [ 9], but often correspond with increased inhalation rates and longer travel durations which could result in a higher dose of air pollutant inhalation [ 10].
