    Study Notes

    Definitions and Concepts

    • Ambient Air Quality: Refers to the overall quality of the air in a given area, measuring the concentration of pollutants that can affect human health and the environment.

    Pollutants

    • Primary Pollutants: These are the harmful substances released directly into the atmosphere from various sources in their original forms, such as carbon monoxide and sulfur dioxide.
    • Secondary Pollutants: Formed through chemical reactions in the atmosphere after primary pollutants have been emitted, including ozone and particulate matter.

    Legislation and Air Pollution

    • RA 8749: Known as the Clean Air Act of 1999 in the Philippines, it provides a legal framework for the improvement of air quality and defines what constitutes air pollution.
    • Constitution of Air Pollution According to RA 8749: Air pollution is identified as the presence of substances in the air that can be harmful to health or the environment.
    • Primary Concern of Air Pollution: RA 8749 emphasizes the need to protect public health and the environment from the detrimental effects caused by air pollution.

    Pollution Characteristics

    • General Amount of Pollution: The term used to describe the collective pollution present in a broad area is referred to as "ambient air pollution."
    • Directly Released Pollutants: These pollutants enter the atmosphere straight from their source in a harmful state, impacting air quality immediately upon release.
    • Hazardous Form Pollutants: Some pollutants transform into dangerous chemicals after being released into the air or through subsequent chemical reactions in the atmosphere.
