Description
Nitrogen Oxides and Sulfur Oxides  contributes a great amount in formation of ground ozones combined with volatile organic compounds and the help of the heat and sunlight  form in any type of combustion process  When in air, can easily form acids (acids aerosols), therefore, nitrogen contributes in formation of acid rain acidifies soils and open water  Can form nitrate particles when reacting with solid particles (salts) and can stay in the air or come back to the soil surface through rain and contaminate soil.  Regardless of source of nitrogen oxides, nitrogen oxides can travel very far like ozone.  A major affect they have on our bodies is harm to our lungs and other breathing organs. The intensity and location of damage to our body depends on the forms of the nitrogen oxides. o If it is water soluble, it causes damage to upper areas of our respiratory system (e.g. nose, bronchioles, throat) o If it is not water soluble, it will reach lower areas of our lungs and affect small airways.  Nitrogen oxide gases are harmful to those who already have respiratory problems (e.g. Asthma – most common) or weak immune system. Children are more vulnerable to such a negative effect.  How are Sulfuric Oxides produced: usually during the burning of coal (soft coal) and oil and as well from the extract of metals from ores.  Sulfur Dioxides are very soluble and can dissolve in water vapour or water molecules in air and forms acid rain (similar to nitrogen dioxide).  Sulfur oxide gases can react with other solids and form solid sulfates. Lead  Major reason lead is found in air (especially in urban areas) is b/c gasoline was leaded (not anymore)  Young children are particularly sensitive to the aversive effects of lead.  Lead in air can slowly deposi
