Effect of Hydrocarbon and NO_xon Photochemical Smog Formation under Simulated Transport Conditions

Verification of a mathematical model for aerosol nitrate and nitric acid formation and its use for control measure evaluation

“…These control programs are expensive, and the most effective strategies to reduce 0 3 and N0 2 concentrations (Pitts et al, 1983;Chock et al, 1981Chock et al, . 1983Glasson, 1981Glasson, , 1983) are still in question. A key problem faced when selecting between alternative control programs is that the decisions made will also affect the concentrations of a number of currently unregulated but potentially damaging co-pollutants, in particular HN0 3 and AN.…”

Characterisation of semi-volatile hydrocarbon emissions from diesel engines

“…These studies show that reducing HC and NO x concentrations simultaneously leads to a decrease in O 3 , however, this is less than the decrease observed from HC reduction alone (Glasson, 1981). Thus historically it has been known that by controlling HC levels in the atmosphere, O 3 reduction could be achieved in urban areas (Glasson, 1981). In recent years, VOC emissions have been successfully quantified and reduced in many developed cities, however, research shows that longer chain HCs are typically not considered as part of air quality control strategies.…”

“…Smog chamber irradiation studies have also been conducted to investigate ozone formation as a function of the initial concentration of its precursors. These studies show that reducing HC and NO x concentrations simultaneously leads to a decrease in O 3 , however, this is less than the decrease observed from HC reduction alone (Glasson, 1981). Thus historically it has been known that by controlling HC levels in the atmosphere, O 3 reduction could be achieved in urban areas (Glasson, 1981).…”

Research Progress on Photocatalytic/Photoelectrocatalytic Oxidation of Nitrogen Oxides

“…However, the large consumption of fossil fuels, such as coal and petroleum, has led to the excessive emission of nitrogen oxides (NO x ) [1]. The NO x emitted into the atmosphere not only causes acid rain [2,3], photochemical smog [4,5], PM2.5 [6,7], and other environmental problems but also changes the climate and destroys the ozone layer [8]. In addition, NO x severely damages the human heart and lungs and further reduces the efficacy of the human immune system [9], making the human body susceptible to respiratory diseases, such as cough, eye inflammation, chest tightness, nausea, sore throat, and bronchitis [10,11].…”
