Zhengzhou Xinzheng air quality

On June 3, 2024, the air quality was good, and the air quality index was 56.

An air quality index of 56 indicates that the air quality is good and outdoor activities can be carried out normally, but sensitive people should reduce going out. The air quality reflects the degree of air pollution, which is judged according to the concentration of pollutants in the air.

Air pollution is a complex phenomenon. At a specific time and place, the concentration of air pollutants is affected by many factors. Urban development density, topography and meteorology are also important factors affecting air quality.

In addition, the concentration of "negative oxygen ions" is also one of the signs of air quality. According to the standards of the World Health Organization, when the concentration of negative oxygen ions in the air is higher than per cubic centimeter 1000- 1500, it can be called "fresh air".

Measures to solve air quality

1. Publicity should be strengthened to improve the public's sense of responsibility for environmental protection. Protecting the environment and air quality should be done by everyone.

2. Formulate air quality laws or other relevant laws and regulations, put air quality management into the legal track, have laws to follow, and use the strictest legal system to ensure environmental management and governance.

3. Make a long-term plan for clean air quality, treat both the symptoms and root causes, and treat it for a long time. Forced enterprises to transform and upgrade, encourage enterprises to use clean energy, and give financial subsidies. Reasonable industrial layout: This is an important measure to solve air pollution.

Factories should not be too concentrated to reduce pollutant emissions in an area. In addition, chemical plants with raw material supply relations should be put together to reduce waste gas emissions through comprehensive utilization of waste gas.
