Final answer:
The largest sources of particulate pollutants are electric power plants and motor vehicles. Option 1
Step-by-step explanation:
The largest sources of particulate pollutants are electric power plants and motor vehicles. These two sources release significant amounts of particulate matter into the atmosphere, which can have negative impacts on human health and the environment.
Electric power plants burn fossil fuels, such as coal and oil, to generate electricity. This combustion process releases particulate pollutants, including soot and ash, into the air. Motor vehicles, especially those powered by gasoline or diesel, emit pollutants such as fine particles, nitrogen oxides, and volatile organic compounds.
For example, coal-fired power plants release large amounts of fine particles into the air, which can contribute to respiratory problems when inhaled. Similarly, motor vehicle exhaust contains particulates that can cause lung irritation and respiratory issues. Option 1
