Study Notes

Acid Rain

  • The primary cause of acid rain is the release of pollutants such as sulfur dioxide and nitrogen oxides into the atmosphere, which combine with water and oxygen to form acidic compounds.

Effects of Acid Rain

  • A common effect of acid rain on the environment is the damage to trees, lakes, and rivers, and the loss of biodiversity.

pH Range of Acid Rain

  • Acid rain typically falls in the pH range of 4.5 to 5.6, which is more acidic than normal rainwater.

Materials Vulnerable to Acid Rain

  • Materials particularly vulnerable to damage from acid rain include limestone, marble, and other calcium carbonate-based structures.

Ozone Depletion

  • The main cause of ozone depletion is the release of chlorofluorocarbons (CFCs) and other halogenated gases into the atmosphere, which break down ozone molecules.

Consequences of Ozone Depletion

  • A significant consequence of ozone depletion is an increase in UV radiation, which can cause skin cancer and cataracts in humans, and damage to marine life.

Impact on Marine Life

  • Ozone depletion can disrupt marine ecosystems, leading to a decline in phytoplankton populations, which can have a cascading effect on the entire food chain.

Sources of Ozone-Depleting Substances

  • The primary sources of substances that contribute to ozone depletion are chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and halons, which are commonly used in refrigerators, air conditioners, and fire extinguishers.
