Oil, antifreeze, pet feces, car washing detergents and waste water, gasoline drips, spills etc. all are washed from streets into sewers and then to rivers causing water pollution. Studies indicate that stormwater run-off is about as bad for streams as raw sanitary sewage.

What pollutants are regulated by the Clean Water Act?

The Clean Water Act regulates pollutants such as oil and grease, toxic metals, pesticides, and industrial chemicals. These pollutants can come from various sources such as industrial discharges, agriculture runoff, and municipal sewage. The Act sets limits on the amount of these pollutants that can be discharged into water bodies to protect water quality and aquatic life.


What Four ways pollutants are changed or affected int the atmosphere?

Pollutants in the atmosphere can be changed through processes like oxidation, photolysis, deposition, and dilution. Oxidation involves pollutants reacting with oxygen to form new compounds. Photolysis breaks down pollutants using sunlight. Deposition is the removal of pollutants from the atmosphere through settling or washout. Dilution occurs when pollutants are dispersed and mixed with clean air.


Organisms help to clean up pollutants?

Yes, organisms such as bacteria, fungi, and certain plants can help clean up pollutants through a process called bioremediation. These organisms break down or metabolize pollutants into less harmful substances, reducing their impact on the environment. Bioremediation can be a cost-effective and environmentally friendly way to remediate contaminated sites.


Why is fuel cell important to earth?

Fuel cells are important to Earth because they provide a clean and efficient way to generate electricity without producing harmful emissions like greenhouse gases or pollutants. They can help reduce our reliance on fossil fuels and contribute to a more sustainable energy future by using hydrogen, a clean energy carrier that can be produced from renewable sources.


How does the atmosphere clean itself?

The atmosphere cleans itself through natural processes such as rain, wind, and sunlight. Rain washes away pollutants from the air, while wind helps disperse them. Sunlight breaks down pollutants and acts as a natural disinfectant. Additionally, vegetation plays a role in absorbing pollutants and releasing oxygen through photosynthesis.
