Air Pollution Flashcards
Basics about Oxides of Sulphur
1. Source
2. Chemical reactions
- Sulphur containing Fossil Fuels
- Further oxidization of Sulphur dioxide120 t
SO₂ + 2O₂ → 2SO₃
SO₂ + O₃ → SO₃ + O₂
SO₂ + H₂O₂ → H₂SO₄
Medical Problems caused by Oxides of Sulphur.
Bronchitis, Asthma, Emphysema, redness of eyes and tears.
What oxides will cause the following problems?
- Bronchitis
- Acute respiratory diseases
- cardiovascular disorder
- Cancer
- Asthma
- Poor Eyesight
- Tears and Redness
- Headache and Nervousness
- Emphysema
- Pregnancy-related problems.
a. Sulphur dioxide
b. Nitrogen Oxide
c. Carbon monoxide
d. hydrocarbons
e. Sulphur dioxide
f. Carbon mono-oxide
g. Sulphur dioxide
h. carbon mono oxide
i. Sulphur dioxide
j. carbon monoxide
What is the meaning of Emphysema?
To puff up, referring to puffing up of areoles, and damaging their walls, creating shortness of breath.
What pregnancy-related problems can carbon monoxide due to smoking cause?
- Deformed infants
- Spontaneous abortion
- Premature Birth.
What oxides/ chemicals are causing the following phenomenon?
1. Ozone depletion
2. Red Haze in traffic
3. Global Warming
4. Acid rain
5. Atmospheric haze
- CFC and Nitrogen dioxide
- Nitrogen Dioxide
- Carbon dioxide, Methane, Nitrogen Dioxide, CFC
- Oxides of Sulphur and Nitrogen/ ammonium
- Ammonium
Why is the pH of rain 5.6 ?
The formation of carbonic acid as a result of the reaction between rain water and carbon dioxide.
Why is carbon monoxide poisonous?
Carbon monoxide is poisonous due to the formation of carboxyhaemoglobin in the blood, which is 300 times more stable than oxyhaemoglobin, cutting off the supply of oxygen in the brain. 5-6% of carboxyhaemoglobin will cause headaches, nervousness and poor eyesight.
Name all the green house gases.
- Carbon dioxide
- Methane
- Nitrogen Dioxide
- CFC chlorofluorocarbon
- Water Vapor
- Ozone
name indirect effects of global warming on health.
There is an increase in vector-borne diseases
1. Malaria
2. Dengue
3. Sleeping Sickness
4. Yellow Fever
Name the oxides released from the following sources.
Basics about nitrogen oxide
- a natural source of NO2 is the oxidization of the nitrate ion formed as a product of the reaction between N2 and O2 due to lightning.
- Source - Automobile engine at high temperature (1483K) combustion of fossil fuel
How does nitrogen oxide react with ozone
All reactions of Acid rain, and types of acid rain.
There are two types of acid rain, ( when acid from the atmosphere settles on the earth)
Dry Deposit (can happen on both solid and liquid surfaces) - SO2, NO2
Wet deposit - Can be present in form of aerosols, like ammonia/ gases which settle on the ground as snow, rain, fog, etc.
After effect of acid rain
- Dissolves nutrients required for plant growth.
- Leeching of heavy metals due to corrosion of pipes made of lead, copper, and iron.
- corrosion of infrastructure made out of metals, like bridges ( may cause collapses over time)
- Changing chemical compositions of water bodies like lakes, rivers, etc.
