Recently, air pollution in our country has become more and more serious. Many netizens are worried about the impact of air pollution on people. What diseases can air pollution cause? The following editor explains in detail what are the diseases caused by air pollution?
What is air pollution?Air pollution (also known as air pollution), according to the definition of the International Organization for Standardization (ISO), "air pollution (air pollution) usually refers to the fact that certain substances enter the atmosphere due to human activities or natural processes, showing sufficient concentration, To achieve sufficient time, and therefore endanger the comfort, health and welfare of the human body or the environment."
What are the diseases caused by air pollution?Air pollution causes lung cancer, chronic obstructive pulmonary disease, asthma, leukemia and other diseases.
Lung cancer is currently one of the most common malignant tumors in countries around the world, and one in every four cancers is lung cancer. At present, the industry recognized that the main causes of lung cancer are smoking and air pollution. The mortality rate of lung cancer is extremely high. There are 1.2 million new cases in the world every year, and one person dies of lung cancer almost every 30 seconds. Lung cancer is also the cancer with the highest incidence in my country, with an annual incidence rate of 35 people per 100,000 people suffering from lung cancer. Chronic obstructive pulmonary disease, including common chronic bronchitis and emphysema, is a destructive lung disease that gradually weakens the patient's respiratory function. The main factors that cause COPD include smoking and dust. Therefore, avoiding smoking and reducing exposure to dust in the air are effective ways to prevent it.
Every year 100,000 people worldwide die from asthma due to indoor air pollution, and 35% of them are children. Children living in air-polluted environments are more likely to suffer from bronchial allergic reactions, which in the end can lead to allergic asthma and other lung diseases later in life. Dust mites and all kinds of inhalable particulate matter are the culprits that cause asthma in children. Therefore, reducing floating dust and mites in the air is an effective way to prevent asthma in children.
The incidence of leukemia in China is 3 per 100,000 people. Approximately 40,000 leukemia patients are newly added each year, of which 50% are children, and most of them are children between 2-7 years old. The proportion of urban leukemia patients accounts for 30%. Indoor air pollution has become the main cause of leukemia.
Through further analysis and research on the work content and professional technology of multiple monitoring platforms, the air micro-monitoring station compares and analyzes the latest domestic research results and application results, and combines my country’s national conditions and personnel plans of relevant departments with reference to the issued country Standards and documents, in accordance with the combination of advancement, practicability, and objectivity, the combination of information technology and automation technology, as well as the combination of advancement and economy, and the guiding ideology of both management methods and application effects, were finally designed and developed This set of PC-end and mobile-end supporting use and coexistence of atmospheric network quality control platform.
It has the characteristics of low price, small size, low maintenance, intelligence, accuracy, etc., suitable for large area, grid layout, and intensive monitoring. The air quality sensor automatically uploads the monitored data to the big data cloud platform through wireless communication to realize the intelligent monitoring and precise traceability functions of the Internet of Things + big data + cloud computing, and apply it to the grid construction and key sources of urban basic monitoring Monitoring (factories, industrial parks, construction sites, ports, road traffic, scattered coal combustion, "scattered and polluted" enterprises, catering areas, etc.) provides accurate data support for city managers to fully grasp the distribution of pollution in the region. In order to better control urban air pollution for managers.
