Air pollutants
- "Air pollutants" are gases and particles that cause air pollution and are defined by the ordinance of the Ministry of Environment.
- "Specified atmospheric pollutants" are air pollutants that can directly or indirectly harm the health and property of people and the growth of plants and animals. They are defined by the ordinance of the Ministry of Environment.
- "Substances that change climate and ecosystem" are gaseous substances that can cause a change in ecosystem due to global warming.
- The greenhouse gas is one of them, and the rest of them is determined by the ordinance of the Ministry of Environment. "Greenhouse gas" absorbs or re-emits infrared rays and radiant heat to induce a greenhouse effect.
- This includes carbon dioxide, methane, nitrous oxide, hydrogen fluoride, perfluorocarbons, and sulfur hexafluoride. "Volatile Organic Compounds" means petrochemicals, organic solvents, and other substances in hydrocarbons, and the Minister of Environment notifies them in consultation with the representatives of the relevant governmental institute.

Deodorization test
Deodorization refers to measures to remove odor through physically isolating the component of odor by chemically changing the component of the odor or absorbing it. Deodorants include chemical deodorants and physical deodorizers.
Some deodorants do not supply deodorizing substances separately, but perform deodorization functions electrically and mechanically.

Odor pollutants
- "Odor" refers to the smell of hydrogen sulfide, mercaptans, amines, or other irritating gaseous substances that stimulate the smell of the human body, causing discomfort and disgust.
- "Odor emission facilities" refer to facilities, machinery, and equipments that cause odors.
- The Minister of Environment determines it in consultation with the head of the relevant central administrative agency, and declare the ordinance.
- "Complex odor" refers to the smell of two or more odorous substances acting together to stimulate a person's sense of smell, causing discomfort and disgust.
- "Specified odor substance" is a substance that causes odor and is determined according to the ordinance of the Ministry of Environment. The measurement of odor is intended to determine if the emission limit is exceeded. At the outlet and site boundary, it is a principle to measure the odor by the air dilution sensory method. If it is necessary to check whether or not odorous substances are emitted, it is necessary to measure the odorous substances specified by the instrument analysis by the instrumental analysis method.
