Air pollution
How lightning can produce air pollution?
Lightning extremely high temperatures led chemical reactions that can produce harmful gases or substances that pollutes the air.
What is global warming?
Mainly an increase on Earth temperature causing ice melting, oceans levels raising and weird and strong weather.
Which cause of air pollution have been produce more damage to the Earth environment?
Man made (unnatural) causes do more damage to the Earth environment than natural causes. Why?
How particulate matter affect us?
Some particulate matter may enter on our respiratory system and can aggravate heart and lung diseases.
How sulfur monoxide affect us?
Sulfur monoxide affect us narrowing the airways, wheezing and shortness of breath, especially in those with asthma.
Does acid rain be dangerous?
Yes, it is. Acid rain can be harmful for plants, aquatic creatures and infrastructures.
Does carbon monoxide harmful?
Yes, it is. Breath carbon monoxide deprive body of oxygen, causes headaches, fatigue, impaired vision and can kill us.
Can the air pollution be measured?
Yes, with especial devices that tell us the air quality index.
Which is the normal composition of the air?
78% nitrogen, 21 % oxygen and 1% other gases
What is acid rain?
Acid rain is weird rain produced by air pollutants (sulfur dioxide and nitrogen dioxide).
What are the causes of air pollution?

Why ozone is considered air pollutant?
At high altitudes, ozone protect us against of harmful Sun rays. But a low altitudes, ground-level, can be harmful for us.
Why man made (unnatural) causes do more damage to the Earth environment than natural causes?
Because every day too much pollutants are dumped to the air by factories, cars, planes, trains and so on.
Why natural causes do less damage to the Earth environment than unnatural (manmade) causes?
Because volcanos, wild fires, pollen and dust storms do not happen every day.
How our houses can be air polluted?
By smoking, burning gas on stove and heaters.
How cars pollute the air?
Cars burnt fossil fuels (petrol, diesel) dumping direct to the air carbon monoxide and sulfur dioxide.
How volcano eruption can pollute the air?
During volcano eruption are released to the air toxic gases, ashes and heavy particles.
How ground-level ozone affect us?
Ground-level ozone can irritate our respiratory system, produce asthma, reduce lung functions by inflaming and damaging lining of lungs.
Where the ground-level ozone come from?
Ground-level ozone como from cars, power plants and chemical plants exhausts.
How smog affect us?
Heavy smog can be deadly for us because respiratory diseases can be aggravated for. Indeed, low visibility and yellow/black color over the cities can occur.
How can we help to reduce the air pollution?
Many things we can do and every effort counts. We can ride a bike instead of drive a car. We can tell to our family about air pollution. We can tell our parents make pollution check on their cars. We can ride a school bus instead of individual transport to school.
How Nitrogen dioxide affect us?
Nitro dioxide affects our lungs and causes wheezing and increases chances of respiratory infections.
What is nitrogen dioxide?
Nitrogen dioxide is a reddish brown gas.
How nitrogen dioxide is produced?
Nitrogen dioxide is produced when nitric oxide combines with oxygen in the air.
Where we can find nitrogen dioxide?
On cars exhausts and power plants exhausts.
What is ozone?
Ozone is a gas naturally present in the air.
Where we can find particulate matter?
Particulate matter are present in many sources including fossil fuels, dust, smoke, fog and so on.
When smog can appear?
Smog appears when heavy traffic, high temperatures and calm winds exists.
What smog stand for?
Smog stand for combination of gases with water vapor and dust. The word smog in fact come from a mixup of smoke and fog.
How the air on our school environment is polluted?
The air on our school can be polluted by smog produced by cars and kitchens; when we don't switch off electric appliances not in use, when people smoke.
What is the air quality index?
The air quality index indicates the actual pollutants level on the air and how can be hazardous for our health.
Which other problem are associated to smog?
The global warming, green house effect, thinning the upper Ozone layer and acid rain are associated to smog.
What are the unnatural causes of air pollution?
Unnatural means man made pollution by burning fossil fuels (coal, petrol), wood and other substances used in cars, homes and energy plants
Which more we can do to help?
We can switch off lights and electric appliances when not in use. We can join a group dedicated to stop pollution. We can encourage our parents to carpool to work. We can learn more and stays up to date in this matter.
What is smog?
When the 5 major pollutants are together, we called it smog.
How wild fire can pollute the air?
Wild fires produce smoke, dust and ashes that pollute the air.
What is air pollution?
any visible or invisible particle or gas found in the air that is not part of the original normal composition.
Which are the 5 major air pollutants?
carbon monoxide, sulfur dioxide, nitrogen dioxide, particulate matter and ground level ozone
What are the natural causes of air pollution?
forest (wild) fires, pollen, dust storm, vulcano eruption.
What is carbon monoxide?
is a colorless and odorless gas produced when carbon does not burn in fossil fuels like petrol, cooker gas, diesel
Where we can find sulfur monoxide?
mainly on power plants exhaust and cars, airplanes, trains, ships exhaust.
Where we can find carbon monoxide?
on car exhaust, on gas cookers and heaters, on train and airplane exhausts.
What about sulfur monoxide?
sulfur monoxide is produced when coal and fossil fuels are burnt.
