[ Focus on Chemical Machinery and Equipment Network ] A large* study of American adults showed that air pollution and a variety of neurological diseases (including Parkinson's disease, Alzheimer's disease and other dementias) have a significant increase in hospitalization risk Related.
Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipmentPM2.
5 refers to the particulate matter in the ambient air with an aerodynamic equivalent diameter less than or equal to 2.
5 microns.
The particle size is small, the area is large, the activity is strong, and it is easy to be accompanied by toxic and harmful substances.
It can be suspended in the air for a long time, and it is harmful to air quality and visibility.

Although humans have realized the impact of PM2.
5 on health, its relationship with neurological diseases is still *confirmed.

This study surveyed the elderly in the United States, the number of which is as high as 63 million.
Compared with any previous studies on air pollution and neurological diseases, the amount of data used in this study is very extensive.
In addition, consider potential confounding factors, such as socioeconomic conditions.
The results show that for every 5 μg/m3 increase in PM2.
5 concentration per year, the risk of hospitalization for Parkinson’s disease, Alzheimer’s disease and related dementia increases by 13%.

It can be seen that air pollution not only hurts the lungs but also hurts the brain, and is closely related to neurological diseases.
So, what do you know about environmental monitoring equipment ?
Monitoring instrument So, what do you know about environmental monitoring equipment ?
First of all, the concentration of PM2.
5 particles can be measured by monitoring stations located around the city.
The equipment used by these monitoring stations is also quite professional and the cost is high.
Therefore, the researchers further reduced its size on the basis of the conventional air quality monitoring equipment sensor .
In the end, the size of this sensor reached 12 x 9 x 3 mm, which is even smaller than a 1 cent coin.
Although the volume is small, it does not affect the accuracy of its monitoring.

Secondly, the air quality monitor can be used, which is not only a single instrument, but also contains a complete set of environmental monitoring system, which can provide comprehensive monitoring support, including environmental monitoring, evaluation, analysis, application and environmental supervision business co-processing, The system operation and maintenance guarantees the integrated business system functions, and timely discovers the characteristics of pollutants, provides the full-process tracking function of the discovery, confirmation, disposal, and summary of pollution events, and issues early warnings in a timely manner through information and multimedia channels such as mobile apps and the Internet.
To "early detection, early warning, and early treatment".

In addition, there are air quality monitors, whose application significance is to scientifically monitor the environment from a microscopic point of view, and then obtain scientific data about environmental quality, so as to conduct scientific and accurate analysis of environmental quality, and analyze pollutants.
Carry out timely development and treatment to effectively prevent and treat environmental pollution, protect the lives and property of the people of the country, and avoid unnecessary losses to the people due to atmospheric pollution.

In addition, there are lidars that are particularly suitable for applications in densely populated areas.
It emits a laser beam to the high altitude, and then obtains air pollutant data for the distance through which the laser passes.
When lidar is used for networked observation, each laser beam can not only read pollutant data, but also enter atmospheric physics and meteorological model analysis.
While reducing the artificial judgment of atmospheric conditions, the distribution area and propagation speed of the haze can be learned in time.

People need to breathe air to sustain life.
If people want to live a healthy life, breathing clean air is the best policy.
Air pollution is harmful to the human body.
It is everyone's responsibility to care for the environment.
Environmental monitoring instruments help us guard the blue sky and white clouds.
