What strategies can reduce emissions of sulfur oxides and nitrogen oxides to the atmosphere?
The catalytic converter reduces carbon monoxide, as well as unburned hydrocarbons.
The EGR system introduces exhaust gas to the intake, creating a lower combustion temperature, and in turn less oxides of nitrogen.
There are more advanced systems on newer cars, but these are the basics.

How do humans add nitrogen to the atmosphere?
Humans add nitrogen to the atmosphere primarily through the burning of fossil fuels, which releases nitrogen oxides. Agricultural activities, such as the application of nitrogen-based fertilizers, also contribute to nitrogen emissions into the atmosphere.
What energy source is associated with nitrogen emissions?
The combustion of fossil fuels, such as coal, oil, and natural gas, is associated with nitrogen emissions. When these fuels are burned at high temperatures, nitrogen oxides (NOx) are released into the atmosphere, contributing to air pollution and smog formation.
How can we reduce nitrogen oxides?
Nitrogen oxides can be reduced by implementing technologies such as catalytic converters in vehicles and selective catalytic reduction systems in industrial processes to lower emissions. Additionally, using cleaner fuels and improving engine efficiency can also help reduce nitrogen oxide levels in the atmosphere.
Is Acid rain created when water vapor in the atmosphere absorbs carbon dioxide?
Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides, which react with the water molecules in the atmosphere to produce acids.
Does lightning help in nitrogen fixation?
Yes, lightning can help in nitrogen fixation by splitting nitrogen molecules in the atmosphere, which then combines with oxygen to form nitrogen oxides. These nitrogen oxides are washed out of the atmosphere by rain, allowing them to be used by plants as a nutrient.
When fuels such as coal and gas are burned what do they release?
When fuels such as coal and gas are burned, they release carbon dioxide, sulfur dioxide, and nitrogen oxides into the atmosphere, contributing to air pollution and greenhouse gas emissions. These emissions can have detrimental effects on human health and the environment, including climate change and respiratory issues.
What are the emissions from coal combustion at thermal power plants?
Oxides of Nitrogen Oxides of Sulphur
Where do nitrogen oxides, a harmful air pollutant, originate from?
Nitrogen oxides, a harmful air pollutant, originate mainly from vehicle emissions, industrial processes, and combustion of fossil fuels.
Where does sulfur oxides and nitrogen oxides in the air come from?
Sulfur oxides and nitrogen oxides in the air primarily come from the burning of fossil fuels in vehicles, power plants, and industrial processes. When fuel containing sulfur and nitrogen is burned, these elements combine with oxygen in the air to form sulfur oxides (SOx) and nitrogen oxides (NOx), which are then released into the atmosphere.
How does oxides of nitrogen come into the atmosphere?
Nitrogen oxides are primarily emitted into the atmosphere through the combustion of fossil fuels in vehicles and power plants. They are also released during industrial processes and biomass burning. Once in the atmosphere, nitrogen oxides can react with other compounds to form pollution such as smog and acid rain.
What is a principal cause of acid rain?
Acid rain is caused by emissions of sulphur dioxide and nitrogen oxides which react with the water molecules in the atmosphere to produce acids.Nitrogen oxides can be produced naturally by lightning strikes and sulphur dioxide is produced by volcanic eruptions and industrial emissions. It also can be from gases from burning coal and oil released into the air.
What are the names of the gases produced by the vechiles?
Carbon monoxide, hydrocarbons, sulfur oxides, particulate matter, and nitrogen oxides (There are also bromine emissions from leaded gasoline).
