Finally, decades of research have provided no evidence of an extrapulmonary transport (including via olfactory neuronal pathways) of particles associated with cigarette smoking; smoking exposes the individual to literally kilograms of a particulate combustion product that includes ultrafine particles. George Often, senior technical leader for air emissions and combustion product management at the Electric Power Research Institute, says that while this may be a low-cost approach to achieving moderate reductions in mercury emissions, larger plants will retrofit with other technologies to meet the requirements of the Clean Air Interstate Rule. In addition to the possible long-term damage that many of the mosquito coil pollutants may cause, the researchers concluded that significant acute health effects, including asthmatic reactions and eye and respiratory irritation, could be expected from exposure to the combustion product |
