write a note on the affect of air pollution on Human being, plant and animals

Answer 1

 



What are the effects of air pollution?

Below are a few key effects of air pollution. The last page on FactSheet has some specific air pollution incidents that are worth checking out.

Acidification:
Chemical reactions involving air pollutants can create acidic compounds which can cause harm to vegetation and buildings. Sometimes, when an air pollutant, such as sulfuric acid combines with the water droplets that make up clouds, the water droplets become acidic, forming acid rain. When acid rain falls over an area, it can kill trees and harm animals, fish, and other wildlife. 


Acid rain destroys the leaves of plants.
When acid rain infiltrates into soils, it changes the chemistry of the soil making it unfit for many living things that depend on the soil as a habitat or for nutrition. Acid rain also changes the chemistry of the lakes and streams that the rainwater flows into, harming fish and other aquatic life.

Eutrophication:
Rain can carry and deposit the Nitrogen in some pollutants on rivers and soils. This will adversely affect the nutrients in the soil and water bodies. This can result in algae growth in lakes and water bodies, and make conditions for other living organism harmful.

Ground-level ozone:
Chemical reactions involving air pollutants create a poisonous gas ozone (O3). Gas Ozone can affect people’s health and can damage vegetation types and some animal life too.

Particulate matter:
Air pollutants can be in the form of particulate matter which can be very harmful to our health. The level of effect usually depends on the length of time of exposure, as well the kind and concentration of chemicals and particles exposed to. Short-term effects include irritation to the eyes, nose and throat, and upper respiratory infections such as bronchitis and pneumonia. Others include headaches, nausea, and allergic reactions. Short-term air pollution can aggravate the medical conditions of individuals with asthma and emphysema. Long-term health effectscan include chronic respiratory disease, lung cancer, heart disease, and even damage to the brain, nerves, liver, or kidneys. Continual exposure to air pollution affects the lungs of growing children and may aggravate or complicate medical conditions in the elderly.

NOTES
Particulate matter can come in almost any shape or size, and can be solid particles or very very tiny liquid droplets.

Big particles can be between 2.5 and 10 micrometers (about 25 to 100 times thinner than a human hair).

Small particles are smaller than 2.5 micrometers (100 times thinner than a human hair).

Answer 2

Air Pollution has been one of the biggest problems that the humans have been facing over the years. This is not an issue for some specific country; it is important for people across the world to curb the issues related to air pollution. The Air pollution index has been at all-time highs for quite some time. The effects of air pollution can be severe and very impacting to your overall health.

1. Breathing polluted air puts you at a higher risk for asthma and other respiratory diseases. Ozone and traffic pollutants can trigger an asthma attack, there is also emerging evidence for onset of asthma associated with exposure to pollution.

2. Air pollutants are mostly carcinogens and living in a polluted area can put people at risk of Cancer. Cancer risk increases with exposure to toxic air contaminants, such as benzene, formaldehyde and diesel particulate matter.

3. Brain requires a high amount of energy. Hence there is a high demand for oxygen supply. Decreased oxygen content in air leads to inadequate energy supply to the brain. There is also the risk of headaches, depression, anxiety, etc.
