Smog/Ground level ozone By: Emily Khalili and Audrey Lopez

What is ground level ozone (Smog)? Definition: mixture of harmful air pollutants (fog, smoke etc.) in atmosphere Ozone is the chemical of O3 Layer of smog in atmosphere- troposphere

What is ground level ozone (Smog)? How is it created? Chemical reaction of oxides of nitrogen (NO3) and volatile organic compounds (VOC) Sunlight stimulates the chemical reaction Chemical reaction NO3 + VOC + Sunlight = 03

Causes of Smog/Ground Level Ozone Lots of smog b/c of the abundant emission of NO3 and VOC What are sources of NO3 and VOC? Gasoline-powered vehicles (cars) Lawn equipment Industrial facilities Burning of fossil fuels

Causes of Smog/Ground Level Ozone More common in urban cities Why? Most cars and industrial facilities are located there High ozone levels usually during the summer Why? More sunlight

Health Effects of Smog/Ground level ozone Children at high risk b/c lungs are still developing Smog targets the lungs Breathing problems b/c of smog Chest pain/coughing Bronchitis Asthma Lungs vulnerable to infections Permanent scaring of lung tissue

solutions Using a cleaner commute helps with lowering the ozone level such as: Carpooling Riding a bike Conserving electricity Mulching/composting leaves or yard waste

outlook The Clean Air Interstate Rule: A rule which is only effective in 27 states on the East Regulates air emission from stationary and mobile sources. National Ambient Air Quality Standards Ozone- 0.075 parts per million (volume) 8 hr concentration averaged over 3 years Smog checks Required check of amount of gas emitted from cars and other vehicles
