The toxicity of nitrogen pentoxide.
There is no evidence in the literature that nitrogen pentoxide (N205), the highest known oxide of nitrogen, has ever been the subject of a toxicological investigation. This gas rapidly breaks down to give nitrogen dioxide and oxygen, but is known to be stabilized by the presence of ozone, and several investigators (Schumacher and Sprenger, 1929; Johnston, 1951) have studied the complex system o...
متن کاملThe Rate of Decomposition of Nitrogen Pentoxide at Very Low Pressures.
(3) The reaction time of the direct growth-response is constant for a particular intensity of illumination, provided that the duration of the exposure period exceeds a certain value. Below that value the reaction time increases as the exposure time decreases. This is also true for the phototropic response. (4) The manner in which the reaction time of each mode of response varies as a function o...
متن کاملToxicity of nitrogen dioxide: an introduction.
Many questions, needed to advance our understanding of the mechanism of injury from high-level NO2, remain unanswered to date. This is partly due to the limited interest in the toxicity of high-level exposures, and partly due to the public pressure and interest to study the effects of low- (environmental) levels. However, the effects of exposure to high-level NO2 are of great interest to the mi...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
