“…Numerous toxicological studies have examined cardiopulmonary health effects of a variety of ambient gas and particulate pollutants such as ozone, real-time ambient particulate matter (PM) and source-specific pollutants, including power plant combustion collected PM, diesel exhaust (DE), nano materials, asbestos and even biofuel exhausts (Brito et al, 2010; Golomb at al., 2012; Kodavanti et al, 2000, 2005, 2011, 2013; Shannahan et al, 2012; Tong et al, 2009). Pulmonary injury from inhalation of these pollutants could be influenced by chemical composition, physical characteristics, surface reactivity, the level of exposure, the method of exposure, the lung deposition of specific pollutant, longevity of exposure and more importantly the animal species and strain related factors.…”
