How does the combustion of car gasoline affect the ozone?

Question

This is for a school powerpoint presentation. Any information regarding the question would be much appreciated! Thanks!

Answer 1

it has very little effect or no reffect on the ozone layer but it dose cause ozone pollution. nitrous oxide and nitrogen dioxide as they react release oxigen free radicles which can form ozone.

Answer 2

You need to distinguish between tropospheric ozone and stratospheric ozone.  There is little effect of car exhaust on stratospheric ozone, as everyone else has mentioned, so perhaps your presentation is on tropospheric ozone.  Gengi gave a decent answer for tropospheric ozone, google "photochemical smog ozone" for more details on the link between internal combustion engines and tropospheric ozone.

Answer 3

Human activity since the industrial revolution has increased the concentration of various greenhouse gases, leading to increased radiative forcing from CO2, methane, tropospheric ozone, CFCs and nitrous oxide. Molecule for molecule, methane is a more effective greenhouse gas than carbon dioxide, but its concentration is much smaller so that its total radiative forcing is only about a fourth of that from carbon dioxide. Some other naturally occurring gases contribute very small fractions of the greenhouse effect; one of these, nitrous oxide (N2O), is increasing in concentration owing to human activity such as agriculture. The atmospheric concentrations of CO2 and CH4 have increased by 31% and 149% respectively since the beginning of the industrial revolution in the mid-1700s. These levels are considerably higher than at any time during the last 650,000 years, the period for which reliable data has been extracted from ice cores.[27] From less direct geological evidence it is believed that CO2 values this high were last attained 20 million years ago.[28] Fossil fuel burning has produced about three-quarters of the increase in CO2 from human activity over the past 20 years. Most of the rest is due to land-use change, in particular deforestation.[29]

Recent increases in atmospheric carbon dioxide (CO2). The monthly CO2 measurements display small seasonal oscillations in an overall yearly uptrend; each year's maximum is reached during the Northern Hemisphere's late spring, and declines during the Northern Hemisphere growing season as plants remove some CO2 from the atmosphere.

The monthly CO2 measurements display small seasonal oscillations in an overall yearly uptrend; each year's maximum is reached during the Northern Hemisphere's late spring, and declines during the Northern Hemisphere growing season as plants remove some CO2 from the atmosphere.

The present atmospheric concentration of CO2 is about 385 parts per million (ppm) by volume.[30] Future CO2 levels are expected to rise due to ongoing burning of fossil fuels and land-use change. The rate of rise will depend on uncertain economic, sociological, technological, and natural developments, but may be ultimately limited by the availability of fossil fuels. The IPCC Special Report on Emissions Scenarios gives a wide range of future CO2 scenarios, ranging from 541 to 970 ppm by the year 2100.[31] Fossil fuel reserves are sufficient to reach this level and continue emissions past 2100, if coal, tar sands or methane clathrates are extensively used.[32]

Answer 4

its got carbon monoxide and other noxious gases in it and even though it isnt much , there are a lot of cars in the world and it all adds up and creates like a blanket over the world

heres a site about green house affect and the ozone http://www.adrian.edu/chemistry/th/Somel...

Answer 5

After we got rid of all of those CFC's and cost millions of dollars....  Scientists finally realized that, Hey, the hole has always been there and nothing is happening to it....  They also realized that those CFC's weren't making it up that high....  I wonder how you increase in elevation, the air and all other gasses get less dense... Yet somehow, CO2 and all these other bad ones, which are usually heavier than any other gas, climbs all the way up to that ozone layer?  Kind of makes you wonder.

Let's see, 385 parts per million...  Hmmmmm  1,000,000 / 385 equals about one 2500th of the total...  And that is causing global warming?  YOU GOTTA BE KIDDING!!!!

Answer 6

Not much. It's mainly CFC's that destroys the ozone layer.

B t w, the ozone layer and global warming is two separate issues. More info on how they are connected here: http://www.ucsusa.org/global_warming/sci...

Edit: Sorry, I just realized that I might have misunderstood your question. (I thought you where talking about the ozone layer)

Ozone in the trophosphere is indeed a strong greenhouse gas (while the ozone in the stratosphere is protecting us). This link may be to some help for you:

Answer 7

carbon is the most cause. the black stuff you see on the muffler

or coming out of semi stacks.

Answer 8

combustion of car gasoline turns to some sort of smoke that is polluting the air and destroys the o zone layer which in turn causes global warming..

Answer 9

Not much.  Car exhaust contains CO, CO2, Nitrogen Oxides and other things but not the CFCs that damage the Ozone layer.
