Study Notes
Environmental Pollutants and Their Effects
- Noise pollution can cause hearing loss, stress, and other health problems.
- Refrigerants, such as chlorofluorocarbons (CFCs), contribute to ozone depletion.
- Ozone (O3) plays a crucial role in the Earth's atmosphere, absorbing ultraviolet (UV) radiation.
Ozone Depletion and Greenhouse Gases
- Chlorofluorocarbons (CFCs) are the primary cause of ozone depletion in the stratosphere.
- Carbon dioxide (CO2) is a greenhouse gas, currently at a concentration of approximately 414 parts per million (ppm) as of 2021.
- Methane (CH4) contributes to the greenhouse effect, responsible for around 18% of the phenomenon.
Human Health and Waste Management
- The typical frequency range of human hearing is between 20 Hz and 20,000 Hz.
- Municipal Solid Waste (MSW) is a significant environmental concern.
Atmospheric Processes
- Ozone (O3) is broken down into oxygen (O2) through the action of ultraviolet (UV) radiation in the stratosphere.
- The main function of ozone (O3) in the Earth's stratosphere is to absorb ultraviolet (UV) radiation, protecting the planet from harmful radiation.
