This set of Environment Management test focuses on “Effects and Control Measures of Air Pollution”.
1. Which is responsible for the greatest exposure to carbon dioxide for living organisms?
a) Hurricanes
b) Soil erosion
c) Vehicles emission
d) Cigarette smoking
View Answer
Explanation: Cigarette smoking is responsible for the greatest exposure to carbon monoxide. Exposure to air containing even 0.001% of carbon monoxide for few hours can cause collapse, coma and even death in the worst case.
2. How excessive water loss takes place in plants?
a) Due to soil pollution
b) Due to mutation
c) Due to air pollution
d) Due to improper seed
View Answer
Explanation: The leaves of plants are damaged when some gaseous pollutants enter the pores of the leaf. Chronic exposure of the leaves to air pollutants can break down the waxy coating that helps prevent excessive water loss in plants.
3. How does asthma cause to human beings?
a) Because of excessive diet
b) Because of water pollution
c) Because of air pollution
d) Because of soil pollution
View Answer
Explanation: Asthma is one of the health impacts that are caused due to air pollution. There are many health impacts especially respiratory impacts on human beings. Asthma is caused due to excessive inhale of sulphur dioxide and smoking.
4. What is the reason for reduced in the plant growth?
a) Excessive exposure to sunlight
b) Excessive exposure to wind
c) Excessive exposure to water pollution
d) Excessive exposure to air pollution
View Answer
Explanation: Reduced in the plant growth is due to the chronic exposure of air pollution on the plants. Reduced plant growth is an effect due to the impact of plants of air pollution. Chronic exposure interferes with photosynthesis and plant growth in the plants.
5. Which dioxide damages the flower process in plants?
a) Sulphur dioxide
b) Carbon dioxide
c) Nitrite dioxide
d) Magnesium dioxide
View Answer
Explanation: Sulphur dioxide released due to air pollution caused damages to living organisms. Higher concentration of sulphur dioxide results in the formation of flowers. The flower buds become stiff and hard. They fall from the plants, as they are unable to flower.
6. Human’s respiratory system doesn’t many mechanisms that help to protect them from air pollution.
a) True
b) False
View Answer
Explanation: Human respiratory have many mechanisms to prevent air pollution. The hair in the noise filters out large particles. The sticky mucus in the lining of the upper respiratory tract captures smaller particles and dissolves some gaseous pollutants.
7. What is the main reason for ozone depletion?
a) Releasing of oxygen
b) Releasing of chemicals
c) Releasing of CFCs
d) Releasing of nitrogen
View Answer
Explanation: Chlorofluorocarbons (CFCS) are extremely stable, non-flammable. CFCs leading in the ozone layer depletion. India signed the Montreal Protocol in 1992, which aimed at controlling the production and consumption of ozone depleting substances.
8. Which of the following component is more dangerous to ozone layer?
a) CFCs
b) Nitrogen
c) Halons
d) Sulphur
View Answer
Explanation: Halons are similar to structure to CFCs but it contains bromine instead of chlorine. CFCs and halons migrate into the upper atmosphere after they are released and caused damage to the ozone layer. Halons are more dangerous to the ozone layer than CFCs.
9. Why ozone depletion more over the South Pole?
a) Due to uneven disturbance of CFCs
b) Due to extreme weather conditions in the Antarctic atmosphere
c) Due to cyclonic depression in South Pole
d) Due to extreme pressure
View Answer
Explanation: Despite the fact that CFCs are evenly distributed over the globe, ozone depletion is especially pronounced over the South Pole due to extreme weather conditions in the Antarctic atmosphere.
10. When did India signed the Montreal Protocol?
a) 1990
b) 1991
c) 1992
d) 1993
View Answer
Explanation: India signed the Montreal Protocol in 1992. The aim is to control the production and consumption of ozone depleting substances. It was set up as an example of a successful international agreement.
11. What is the main reason for skin cancer?
a) Due to mutation
b) Due to unhealthy lifestyle
c) Due to alcohol consumption
d) Due to UV radiations
View Answer
Explanation: Ozone depletion causes many harmful health impacts on humans and other organisms. When humans are exposed to Sunlight where due to ozone layer depletion receives direct UV radiations which cause skin burn which further causes skin cancer.
12. How many fundamental approaches are there to control air pollution?
a) One
b) Two
c) Three
d) Four
View Answer
Explanation: Air pollution can be controlled by two fundamental approaches. Those approaches can control air pollution if it applies in effective way. The two fundamental approaches to control air pollution are preventive techniques and effluent control.
13. Why industries location plays an important role with concern to the environment?
a) To get more output from industries
b) To clear the forests in order to build the industries
c) To get more income
d) To prevent pollution causing by industries
View Answer
Explanation: Industries should be carefully located in order to minimize the effects of pollution after considering the topography and wind direction. Industries with are in side cities cause more pollution than those which are in outskirts.
14. National Air Quality Monitoring Programme (NAMP) is formed to monitor the air quality.
a) True
b) False
View Answer
Explanation: NAMP aims to determine the present air quality status and trends, and to control and regulate pollution from industries and other sources to meet the ambient air quality standards. It provides background air quality data that is required for industrial sitting and town planning.
