Nitrogen Oxide (NOx) by Haziq Haikal Saipol https://padlet.com/haziqhaikal54/z9c2x2gsllp5 By Group 12 en-us 2018-09-27 01:13:50 UTC 2023-03-28 21:23:22 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Beartoy.png What is NOx? haziqhaikal54 https://padlet.com/haziqhaikal54/z9c2x2gsllp5/wish/286308633 Nitrogen dioxide and nitric oxide are referred to together as oxides of nitrogen (NOx). NOx gases react to form smog and acid rain as well as being central to the formation of fine particles (PM) and ground level ozone, both of which are associated with adverse health effects..]]> 2018-09-27 01:17:59 UTC https://padlet.com/haziqhaikal54/z9c2x2gsllp5/wish/286308633 Primary Pollutant of NOx haziqhaikal54 https://padlet.com/haziqhaikal54/z9c2x2gsllp5/wish/286308944 A primary pollutant is an air pollutant emitted  directly from a source. Its is emitted directly by autos, and industry. Fossil fuel combustion (gasoline and diesel engines) is the main source for nitrogen oxides in urban areas, while microbial activity in the soil and agricultural practices such as the use of synthetic fertilizers are its main sources in rural areas. Exposure to nitric oxides may cause an inflammation of the respiratory tracts.

It’s include ozone, which is formed when hydrocarbons (HC) and nitrogen oxides (NOx) combine in the presence of sunlight (NO2), which is formed as NO combines with oxygen in the air. Acid rain also formed when sulfur dioxide or nitrogen oxides react with water.

2.      An exposure of 0.06-0.1 ppm of N02 for 2-3 yrs causes acute respiratory disease.
3.      NO2 oxides cellular lipids, form bonds with haemoglobin, reduces the efficiency of oxygen transport and disrupts some cellular enzyme system.
4.      About 500-600 ppm of N02 for 2-10 days results in pulmonary haemorrhage, lung cancer and gum-inflammation.
5.      330-1500 ppm of NOx present in cigarette smokes develop lung disease in victim ans lowers the resistance to influenza and bronchitis.

2.      Higher concentrations of N02 (10-50 ppm) checks the metabolic activities and 🤬 the photosynthesis in plants.

2.      NO2 along with hydrocarbon produces peroxide which combine with ozone to cause crack in rubber.
3.      NO2, O3 and hydrocarbon in sunlight form PAN responsible for photochemical smog.
