Module 4 Flashcards
Introduction
This module discusses the nature, types, sources, and effects of air pollution. It gives the general status of air pollution in the country and summarizes the salient features of the Clean Air Act and suggests ways by which to prevent pollution.
is the presence of substances in the air in amounts harmful to humans, other animals and/or plants.
Air pollution
The criteria in determining air pollutants are:
- Particulates or very fine solids, collectively referred to as total suspended particulates (TSP)
- Particulate matter 10um in diameter
- Carbon monoxide
- Lead
- Ozone
- Sulfur Oxide
7.Nitrogen Oxide
also commonly called soot, microscopic particles suspended in the air.
Particulates or very fine solids, collectively referred to as total suspended particulates (TSP)
a toxic, odorless, colorless gas, is produced from the incomplete burning of fossil fuels or any carbonaceous material.
Carbon monoxide
is formed by a series of complex reactions involving nitrogen oxides, volatile, organic compounds, and sunlight.
Ozone
are the product of chemical reaction of sulfur and oxygen from the air.
Sulfur Oxide
are produced from high temperature combustion which causes the combination of nitrogen and oxygen gases, which are naturally present in the air.
Nitrogen Oxide
Main Sources of Air Pollution
- Mobile Sources
- Stationary Sources
- Anthropogenic Sources
- Other Sources
About 3.9 million vehicles are registered in the whole country. Around 70% use gasoline and 30% use diesel.
Mobile Sources
that account for most of the air pollution are power plants, cement plants and oil refineries.
Stationary Sources
(human-caused) sources of air pollution have been increasing with increasing urbanization, industrialization, and increasing vehicle pollution.
Anthropogenic Sources
persistent organic pollutants are group of substances that are not uncommon in our everyday lives but are extremely toxic.
Other Sources
was passed in 1999
The Clean Air Act, or Republic Act 8749
are areas with similar climate, meteorology or topology which affect the diffusion of pollution in the atmosphere or areas which share common interest or face similar development programs.
