Tianjin Atmospheric Emission Standards

Tianjin air emission standards stipulate petroleum refining and petrochemistry, pharmaceutical manufacturing, rubber product manufacturing, coating and ink production, plastic product manufacturing, electronics industry, automobile manufacturing and maintenance, printing and packaging printing, Control requirements for volatile organic compounds emissions from furniture manufacturing, surface coating, ferrous metal smelting and other industries.

This standard applies to the emission management of volatile organic compounds in the exhaust gas of existing and newly built sewage units, as well as the environmental impact assessment of construction projects, the design of environmental protection facilities, the acceptance of completed environmental protection and the volatile organic compounds after production. emissions management.

Hazards of air pollutants:

1. The main hazards of sulfur dioxide SO2: forming industrial smog, making it difficult to breathe at high concentrations. It is the culprit of the famous London smog incident; entering the atmosphere Afterwards, it is oxidized to sulfuric acid to form acid rain in the clouds, which is very harmful to buildings, forests, lakes, and soil; it forms suspended particles, also known as aerosols, which enter the lungs as people breathe, causing direct damage to the lungs.

2. The main hazards of suspended particulate matter TSP: it enters the lungs with breathing and can be deposited in the lungs, causing respiratory diseases. Particulate matter easily adheres to a variety of harmful substances, some of which are carcinogenic, and some of which can induce pollen allergies. They are deposited on the leaves of green plants, interfering with the process of plants absorbing sunlight and carbon dioxide and releasing oxygen and water, thereby affecting the health and growth of plants.

Thick particulate matter concentration will affect the respiratory system of animals; kill microorganisms, cause changes in the food chain, and then affect the entire ecosystem; block sunlight and may change the climate, which will also affect the ecosystem.

3. The main hazards of nitrogen oxide Nox: irritate people's eyes, nose, throat and lungs, increase the incidence of viral infections, such as causing influenza that leads to bronchitis and pneumonia, and induce lung cell cancer. ; Forms urban smog, affecting visibility; destroys leaf tissue and inhibits plant growth; forms nitric acid droplets in the air, producing acid rain.

To sum up, Wen Wurui, director of the Tianjin Municipal Environmental Protection Bureau, said that this year we will strengthen the management measures of coal control, dust control, vehicle control, industrial pollution control, and new project control in accordance with the law, and promote the completion of 236 management tasks. , and strive to continue to maintain a significant decline in the average annual concentration of PM2.5.

Legal basis:

"Tianjin Regulations on the Prevention and Control of Air Pollution"

Article 12

Tianjin implements air pollutant emission regulations A management system that combines concentration control with total emission control of key air pollutants. If pollutants are discharged into the atmosphere, the concentration of pollutant discharge shall not exceed the prescribed emission standards; if key air pollutants are discharged, the total amount control indicator shall not be exceeded.
