How do oxides of Sulphur and nitrogen released in the air pollute the environment?
The oxides of nitrogen can behave as the primary pollutant by producing toxic reaction themselves or they can act as secondary pollutants and combine with other pollutants to form acid rain, photochemical smog, aerosols.
What does oxides of nitrogen cause?
Environmental and health effects of nitrogen oxides Elevated levels of nitrogen dioxide can cause damage to the human respiratory tract and increase a person’s vulnerability to, and the severity of, respiratory infections and asthma. Long-term exposure to high levels of nitrogen dioxide can cause chronic lung disease.
How does Sulphur oxides cause air pollution?
Sulfur oxides also combine with water droplets in the air to make sulfuric acid, which is part of acid rain. Acid rain is bad for plants and fish and other living things. Sulfur oxides combine with other molecules to form particles that contribute to particulate pollution, creating hazy skies with reduced visibility.
How does sulfur dioxide affect the environment?
Environmental effects When sulfur dioxide combines with water and air, it forms sulfuric acid, which is the main component of acid rain. Acid rain can: cause deforestation. acidify waterways to the detriment of aquatic life.
What are the effects of oxide of nitrogen and sulfur dioxide?
What are the health effects of SO2 and NO2? SO2 and NO2 both can cause lung disease. NO2 can also increase your chances of getting viruses. SO2 can cause eye irritation and burning of the skin.
How do sulfur dioxide and nitrogen oxides help cause acid rain?
Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.
Why are the oxides of nitrogen and sulphur harmful for the environment Class 8?
The pollutants like Sulphur dioxide and Nitrogen dioxide combine in the atmosphere and form their acids which are called acid rain. These pollutants are emitted from industries or factories. 1. Acid rain is harmful to aquatic organisms and other animals.
How does nitrogen dioxide get into the atmosphere?
NO2 primarily gets in the air from the burning of fuel. NO2 forms from emissions from cars, trucks and buses, power plants, and off-road equipment.
Where does sulfur dioxide come from?
Sulfur dioxide, SO2, is a colorless gas or liquid with a strong, choking odor. It is produced from the burning of fossil fuels (coal and oil) and the smelting of mineral ores (aluminum, copper, zinc, lead, and iron) that contain sulfur. Sulfur dioxide dissolves easily in water to form sulfuric acid.
Is nitrogen oxide the same as nitrous oxide?
Nitrogen is a molecule composed of two nitrogen atoms, while nitrous oxide is a chemical compound of two nitrogen molecules and one oxygen molecule. Nitrogen makes up 78% of the Earth’s atmosphere and is an inert gas that is colourless, odourless and tasteless.
Do you think sulfur dioxide and nitrogen oxides in the air are harmful or beneficial?
What is nitrogen oxide?
Description. Oxides of nitrogen are a mixture of gases that are composed of nitrogen and oxygen. Two of the most toxicologically significant compounds are nitric oxide (NO) and nitrogen dioxide (NO2). Other gases belonging to this group are nitrogen monoxide (or nitrous oxide, N2O), and nitrogen pentoxide (NO5).
Do oxides of sulphur and nitrogen have a negative impact?
We will study the negative impact of oxides of sulphur and nitrogen when present in excess quantity than the permissible limit. The general term to refer to all oxides of sulphur is SOx. The major oxides of sulphur are sulphur dioxide and sulphur trioxide.
How do oxides of sulphur and nitrogen enter the atmosphere?
Oxides of sulphur and nitrogen are responsible for many natural phenomena. Similarly, oxides of sulphur such as sulphur dioxide enter the atmosphere by natural processes such as volcanic eruptions.
How are nitrogen oxides formed?
The classic example of the formation of nitrogen oxides is by the chemical reaction of atmospheric nitrogen and oxygen during the thunderstorm. The chemical reaction occurs in the presence of lightning to form the nitric oxide which further undergoes reaction with oxygen to form nitrogen dioxide.
What happens when nitric oxide reacts with oxygen?
The nitric oxide will rapidly react with oxygen to form NO 2 (nitrogen dioxide). The rate of nitrogen dioxide production will increase if the reaction occurs between stratospheric ozone and nitrogen oxide. The irritant red haze usually seen in the traffic and congested regions is due to the presence of oxides of nitrogen.
