Multiple choice

What are the two main types of air pollutants regulated by the Clean Air Act?

  1. Criteria pollutants and hazardous air pollutants

  2. Mobile source pollutants and stationary source pollutants

  3. Indoor air pollutants and outdoor air pollutants

  4. Primary air pollutants and secondary air pollutants
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Clean Air Act regulates two main types of air pollutants: criteria pollutants and hazardous air pollutants. Criteria pollutants are those that are harmful to human health and the environment, and for which the EPA has set national ambient air quality standards. Hazardous air pollutants are those that are known or suspected to cause cancer or other serious health problems.

Multiple choice

What are the main sources of air pollution from mining?

  1. Blasting

  2. Hauling

  3. Loading and unloading

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The main sources of air pollution from mining include blasting, hauling, and loading and unloading. Blasting releases dust and other particles into the air, while hauling and loading and unloading can release dust and diesel exhaust.

Multiple choice

What are some ways to reduce air pollution from mining?

  1. Using dust collectors

  2. Watering roads

  3. Covering trucks

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

There are a number of ways to reduce air pollution from mining, including using dust collectors, watering roads, and covering trucks. Dust collectors can be used to capture dust particles before they are released into the air. Watering roads can help to reduce dust emissions from hauling and loading and unloading. Covering trucks can help to reduce dust emissions from hauling.

Multiple choice

What are some of the recent trends in air pollution from mining?

  1. Air pollution from mining is decreasing

  2. Air pollution from mining is increasing

  3. Air pollution from mining is staying the same

  4. It is difficult to say
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

It is difficult to say whether air pollution from mining is increasing or decreasing, as there is no comprehensive data on the issue. However, some studies have suggested that air pollution from mining may be increasing, due to the increasing demand for coal and other minerals.

Multiple choice

What are some examples of pollution prevention?

  1. Using energy-efficient appliances.

  2. Recycling and composting.

  3. Using public transportation or walking instead of driving.

  4. All of the above.
