1. SUSPENDED PARTICULATE MATTER BY JULIEN GONZALEZ AND CHRISTIAN CAMPO

2. WHAT IS IT It is the sum of all solid and liquid particles suspended in air, many of which affect respiration This mix contains dust, pollen soot, smoke, water vapor smog and pollutants Made up of carbon dioxide, nitrogen dioxide ozone lead sulfur dioxide and particulate matter Most of these Fall in to a size of 10 to 0.1 µmµ These particles come in many different size ranges such as coarse, fine and ultrafine.

3. WHAT IS THE ISSUE The main issue with it is that particle consentrations Affect the lungs of humans and other living organisms and affect their life expectancy Particle consentration also affect certain groups more then others particularly elderly people, children, people with a pre-existing heart and lung disease Particle consentration also heavy affects other organizations like plants by the slowing down photosynthesis and affecting soil pH levels They also store heat more and obscure sunlight

4. WHY DOES THIS OCCUR Studies have shown that particles originating from internal combustion engines, coal burning, residual oil combustion and wood burning have strong inflammatory potential. In comparison, wind-blown dust of crustal origin

5. WHERE DOES IT OCCUR This occurs in most city’s but more commonly LDC for they have less environmental restrictions but the top city’s with this are Beijing, China Ahwaz, Iran Ulan Bator, Mongolia Lahore, Pakistan New Delhi, India Riyadh, Saudi Arabia Cairo, Egypt Dhaka, Bangladesh Moscow, Russia Mexico City, Mexico

6. HOW CAN IT BE CONTROLLED The regulation of this is very simple cut down on automobile use and to place more regulations upon coal and wood burning maintain wild fires more Reducing private automobiles in big city’s during certain hours Significantly slowing down mining and closely regulating the waste
