Before Reading: Scan the reading text, look up the vocabulary items and odd one out the one that doesn’t fit the group

E.g Vitamin B, Folic acids, Proteins, Eggs

  1. Mitigate the effects-Reduce the impact-Exceed the threshold
  2. Particles- Carbon dioxide -Dust-Pollen
  3. Masks- Air purifiers- Earplugs- Vitamin B

1)    What is PM and How does it affect human health?

2)    How many people in the world are susceptible to high exposure to PM2.5?

3)    According to the article, which foods should people consume in order to reduce the damage done by PM?

4)    In what respect is human hair compared to a PM particle?

5)    How is the experiment conducted? (Explain in your own words)

7)    According to Baccerelli, what is the urgent action, polluted areas should take?

8)    Which implementations are suggested for the South Asia air pollution deaths

Write a problem solution essay with the information you have learned on how we can reduce the fatal health effects of air pollution.

Answer Key

Mitigate the effects, reduce the impact, exceed the threshold

Particles, Carbon dioxide, Dust, Pollen,

Masks, Air purifiers, earplugs, vitamin B

  1. Pm is a type of air pollutant consisting of small particles of different sizes — from tiny molecular clusters to dust or pollen that we can see. When people inhale them, they go into the lungs cause “epigenetic” changes to our cells — disturbances or mutations that can damage our health.
  2. 92% of the world’s population lives in places where the PM2.5 level exceeds the recommended threshold.
  3. liver, chicken and nuts, amongst other things, and B12 in fish, meat, eggs, milk and some cereals. OR B vitamin supplements/ Food containing rich amounts of vitamin B
  4. In terms of size; the human hair is compared to PM in terms of size
  5. 10 volunteers were being exposed to clean air to see their normal health conditions Then researchers gave polluted air to the volunteers with a type of oxygen mask. Each volunteer was given a B vitamin supplement daily made up of 2.5 mg of folic acid, 50 mg of vitamin B6, and 1 mg of vitamin B12. In the end, researchers found that 4 weeks of vitamin supplements decreased the damage done by PM2.5 exposure by 28-76%.
  1. According to Baccerelli, heavily polluted areas, are urgently needed to validate research findings and develop preventive interventions using B vitamins to contain the health effects of air pollution
  2. It is stated that people should start using masks, air purifiers or any other emerging method to protect themselves; in addition, governments should make regulations and protect people’s health through maintaining air quality
