A
Correct answer
Explanation
The production of bespoke clothing often involves energy-intensive processes, leading to the release of greenhouse gases that contribute to climate change.
What is the most common environmental health hazard?
-
Air pollution
-
Water pollution
-
Soil pollution
-
Noise pollution
A
Correct answer
Explanation
Air pollution is the most common environmental health hazard, and it is responsible for an estimated 7 million deaths each year.
Which of the following is not a source of noise pollution?
-
Cars
-
Factories
-
Airplanes
-
Birds
D
Correct answer
Explanation
Birds are not a source of noise pollution.
Which of the following is an example of a negative externality?
-
Air pollution from a factory
-
Education
-
Traffic congestion
-
Deforestation
A
Correct answer
Explanation
Air pollution from a factory is an example of a negative externality because it imposes costs on society that are not reflected in the market price of the goods produced by the factory.
What is the primary source of plastic pollution in the ocean?
-
Industrial Waste
-
Agricultural Runoff
-
Personal Care Products
-
Single-Use Plastics
D
Correct answer
Explanation
Single-use plastics, such as plastic bags, straws, and utensils, are a major contributor to ocean pollution due to their extensive use and improper disposal.
What is the main cause of ocean acidification?
-
Oil Spills
-
Climate Change
-
Industrial Waste
-
Agricultural Runoff
B
Correct answer
Explanation
Ocean acidification is primarily caused by the absorption of carbon dioxide from the atmosphere into the ocean, which leads to a decrease in pH levels.
Which of the following is not a type of coastal pollution?
-
Oil spills
-
Sewage discharge
-
Agricultural runoff
-
Forest fires
D
Correct answer
Explanation
Forest fires are not a type of coastal pollution, as they are typically found inland.
What is the primary source of liquid waste pollution from dams and irrigation projects?
-
Industrial wastewater
-
Agricultural runoff
-
Municipal sewage
-
Mining activities
B
Correct answer
Explanation
Agricultural runoff is the primary source of liquid waste pollution from dams and irrigation projects, as it contains fertilizers, pesticides, and other chemicals that can contaminate water sources.
How do dams and irrigation projects contribute to the increase in liquid waste pollution?
-
By creating reservoirs that trap pollutants
-
By diverting water away from natural wetlands
-
By increasing the use of fertilizers and pesticides
-
All of the above
D
Correct answer
Explanation
Dams and irrigation projects contribute to the increase in liquid waste pollution by creating reservoirs that trap pollutants, diverting water away from natural wetlands that would otherwise filter pollutants, and increasing the use of fertilizers and pesticides in agriculture.
What are the main pollutants found in liquid waste from dams and irrigation projects?
-
Nitrogen and phosphorus compounds
-
Heavy metals
-
Pesticides and herbicides
-
All of the above
D
Correct answer
Explanation
Liquid waste from dams and irrigation projects can contain a variety of pollutants, including nitrogen and phosphorus compounds, heavy metals, pesticides and herbicides, and other toxic chemicals.
Which of the following is not a major source of pollution in India?
-
Industrial emissions
-
Vehicle emissions
-
Agricultural runoff
-
Deforestation
D
Correct answer
Explanation
Deforestation is not a source of pollution, but rather a result of it. Deforestation can lead to increased erosion and sedimentation, which can pollute water sources. However, deforestation itself is not a source of pollution.
What are some of the sources of noise pollution regulated under the Noise Pollution (Regulation and Control) Rules, 2000?
-
Industrial machinery
-
Construction activities
-
Transportation vehicles
-
Loudspeakers and public address systems
-
All of the above
E
Correct answer
Explanation
The Noise Pollution (Regulation and Control) Rules, 2000 regulate noise pollution from a variety of sources, including industrial machinery, construction activities, transportation vehicles, loudspeakers and public address systems.
What are the primary sources of pesticide and herbicide contamination in aquatic ecosystems?
-
Agricultural runoff
-
Industrial discharge
-
Domestic wastewater
-
Atmospheric deposition
A
Correct answer
Explanation
Agricultural runoff is the major source of pesticide and herbicide contamination in aquatic ecosystems, as these chemicals are extensively used in crop production and can be easily transported to water bodies through surface runoff or leaching.
What is the primary environmental concern associated with the development of large-scale solar farms?
-
Habitat Loss
-
Water Consumption
-
Air Pollution
-
Noise Pollution
A
Correct answer
Explanation
The primary environmental concern associated with the development of large-scale solar farms is habitat loss, as the conversion of natural land for solar installations can disrupt ecosystems and displace wildlife.
Which of the following is NOT a common type of environmental health indicator?
-
Air quality
-
Water quality
-
Soil quality
-
Noise levels
D
Correct answer
Explanation
