What are the hazards caused by dust pollution from building construction?

For dust pollution, it is composed of large particles in size, which is often blocked in the upper respiratory system, if the dust particles are below 10 microns, they will enter the lower respiratory tract, and below microns, they will accumulate in the alveoli, causing a series of diseases, and in severe cases, it can lead to lung failure and death.

1. The necessity of studying the damage of construction dust pollution to human health Construction dust is caused by construction human activities, and its dust particles will move with air flow under the influence of construction human activities, and finally become fine particles, which are easy to be sucked by people, and once they enter the lungs, they will cause a series of diseases and even endanger people's lives. Specifically, in the process of building construction, a large amount of dust suspended due to the activities of construction personnel or the operation of machinery is controlled, which will not only increase the dust concentration, but also reduce the air quality, especially in large cities, the dust concentration has seriously exceeded the standard. Because the dust contains a large amount of heavy metals such as carbon, hydroxide, sulfur, chlorine, fluorine, etc., and it is easy to produce poison after reaction, it will not only affect the growth of surrounding plants, but also affect people's health.

After all, dust particles containing heavy metal elements will move with the air, and once the smile particles enter people's respiratory system and accumulate in the alveoli, they will cause a series of diseases. In addition, dust contains a large number of bacteria and viruses, and dust will become a medium for bacteria and viruses to accelerate the spread and seriously affect people's health. In addition, the civil problems caused by the dust problem on the construction site will also increase, which not only cannot ensure the smooth progress of the construction and ensure the quality of the construction, but also will cause significant losses to the construction unit.

Therefore, the corresponding research on the health damage of construction dust pollution has become an urgent problem for construction enterprises.

2. Problems encountered in the evaluation of health damage caused by construction dust pollution Insufficient research on the degree of dust pollution in construction At present, the main sources of dust pollution in construction are cement, construction sites and building material piles, etc., and only the emission of particulate matter related to construction is evaluated in the evaluation, and if only the emission of cement materials is emphasized, it is not possible to comprehensively analyze the particulate matter emission of the entire construction activity. After all, the discharge height is limited, and the sedimentation degree is relatively fast. Therefore, it is not possible to evaluate the proportion of particulate matter emitted by emission sources and construction emissions to total emissions based on the emission inventory, and it is not possible to achieve the actual share rate in the air.

Dust pollution from construction mainly causes the increase of dust particles in the air, making the ambient air turbid, and the fine particles are inhaled into the body to cause lung diseases and other respiratory diseases.

The harm of dust is still multifaceted, dust will cause haze, and sand source is one of the reasons for the formation of haze, inducing the occurrence of people's diseases, such as cancer, lung disease, etc.

With the rapid development of urban construction, the number of construction sites in various places is increasing rapidly, and the dust caused by all aspects of construction has become an important factor leading to air pollution. With the in-depth development of the blue sky defense war, strengthening the prevention and control of dust pollution at construction sites has become an important task of urban environmental governance.

Dust control measures at the construction site:

1. Law enforcement personnel go deep into the construction site, widely publicize the laws and regulations related to site management and related law enforcement procedures and punishment standards, enhance the legal awareness of the construction party, and urge its civilized construction.

2. Register the project name, development unit, construction unit, pavement hardening, fence setting, contact information and other relevant information of each construction unit in the urban area in detail, and establish a civilized construction file for site management according to the specific conditions of each construction site.

There are many, such as bringing dust to the streets and polluting street hygiene. It affects people's physical and mental health.

Extended information: Human beings can be defined at biological, spiritual, and cultural levels, or a combination of these definitions. Biologically, humans are classified as hominoids, chromosome 2 and orangutan nail chromosome centromere fusion (equilibrium translocation) association mode proximity of more than 16n, and multiple interarm inversions, the rest of the chromosomes have strong homology, is a higher animal.

On a spiritual level, man is described as being able to use the concept of a variety of souls that are believed to be associated with divine forces or beings in religion. In cultural anthropology, human beings are defined as beings capable of using language, with complex social organizations and technological developments.

1.Contamination by soil, dirt and other attachments carried by construction vehicles;

2.Detachable and reusable windproof and dust suppression nets are arranged around the construction site, which can reduce the wind speed by 86% and effectively inhibit the spread of dust on the construction site;

3.Dust pollution of building materials.

Dust protection measures. 1. For the cement, ash, sand and gravel and other materials that are easy to produce dust pollution stacked in the construction site, a closed fence not lower than the height of the stacked objects shall be set up around them; The outside of the engineering scaffold is closed with a dense safety net.

2. Within 30 days after the completion of the project, level the construction site and remove the accumulated soil and piles.

3. Do not use air compressors to clean the dust of vehicles, equipment and materials.

4. The ground of the construction site is hardened.

5. When carrying out construction operations that produce a large amount of mud, it is equipped with corresponding mud pools and mud ditches to ensure that the mud does not flow out, and the waste slurry is transported by sealed tankers.

6. Use ready-mixed mortar.

7. Set up a hard airtight enclosure of not less than 2 meters around the construction site.

8. Set up vehicle washing facilities and supporting drainage and mud sedimentation facilities in the construction site; The transport vehicle can only leave the construction site after it has been desilted and rinsed.

9. If the construction waste and engineering residue cannot be cleared and transported within 48 hours, a temporary stacking yard shall be set up in the construction site, and the temporary stacking yard shall take dust-proof measures such as fencing and covering.

10. If bulk materials, construction waste and muck are transported on the building, they shall be cleared and transported in a closed manner, and they shall not be thrown or scattered in the air.
