Release date: 2015-03-10 Each year, there are approximately 1.4 million cases of lung cancer worldwide, which have become the most common cancer in the world for more than two decades. It has been known that smoking and occupational exposure can lead to an increase in lung cancer patients. However, in some large cities in China, health and workplace safety conditions have improved despite the decline in the number of people smoking. However, the upward trend of lung cancer can still be observed. Scholars in the United States and China have published research on the pollution of PM2.5 and the risk of lung cancer in the Journal of Environmental Protection (Environmental Protection) published in the Journal of Scientific Research Press in June 2014. Scholars use Western countries to influence the text. The study of force examined the association between PM2.5 and lung cancer (see original text) with the goal of presenting some of the research results of the Chinese community. The relationship between these lung cancer cases and PM2.5 pollution may be relatively new in China, but Western countries have been studying for decades. These findings can provide a basis for further research in the country and help to establish a more comprehensive national pollution control policy. Scholars have proposed two views: long-term exposure to PM2.5 is associated with an increased incidence of lung cancer; systematic research is necessary in China. The chemical composition of particulate matter varies with size, so the impact on human health depends on the size of the contaminant. The human body cannot screen out tiny particles, so dust, especially particles smaller than 2.5 microns (PM2.5), can enter the alveoli of the lungs (where gas is exchanged). These particles not only negatively affect the gas exchange in the lungs, but also penetrate the lungs into the bloodstream, causing serious health problems. Research by American research institutions In 1995, the American Cancer Society (ACS) sponsored a study that showed an increase in annual mortality due to cardiopulmonary disease and lung cancer as the concentration of fine particles increased. This study was closely watched in 1997 as a new standard used by the US Environmental Protection Agency (EPA) to support national ambient air quality PM2.5. The follow-up study of ACS in 2002 showed that PM2.5 pollution levels were associated with increased risk of cardiopulmonary function and lung cancer mortality. If the average concentration of PM2.5 increases at a rate of 10 μg/m3, the risk of death for various natural causes increases by approximately 4%, the risk of death from cardiopulmonary disease increases by 6%, and the risk of death from lung cancer increases by 8%. Coal is still China's main energy source, releasing SOx during the burning process. Developing clean coal technology (which is what Chai Jing calls for coal washing) and or switching to alternative fuels (which are currently not feasible) may reduce China's PM2.5 pollution. The relationship between the relative risk of lung cancer mortality and the change of PM2.5 concentration of 10 μg/m3 has changed from 8% in 1979-1983 to 13% in 1999-2000, according to the two groups of PM2.5 data. The average value is 14%. European research institute research In 2007, Nawrot TS and other scholars used data from 15 European countries to report the association between PM2.5 and male lung cancer mortality. For men, the national PM2.5 level increased by 5μg/m3, and the mortality rate was standardized by age and smoking rate. The mean PM2.5 increased by 17.7% at the end of the year. Similarly, European studies also support a positive correlation between PM2.5 and lung cancer. In 2013, a study conducted by a European consortium reported lung cancer incidence and air pollution in 17 countries in Europe, indicating the relationship between exposure to airborne particulate matter and lung cancer, especially in Europe (pulmonary The incidence of adenocarcinoma, which greatly increases epidemiological evidence. Chinese research data is limited In developing countries, attention to pollution is not low, but the data is not comprehensive enough to conduct reliable statistical research. The lack of systematic research on the relationship between PM2.5 and lung cancer incidence in China is largely due to the fact that the impact of PM2.5 pollutants on health was only caused by the US Embassy in Beijing after the release of PM2.5 data. Public attention. Domestic experts hold different views on the relationship between smog and lung cancer. Some people deny that Beijing PM2.5 pollution is the cause of the increase in lung cancer cases. Because of the lack of local scientific research data, it takes at least 10 years of data to prove this causal relationship. But scholars believe that decades of Western research evidence can be used. It is very necessary to carry out relevant system research in China. We are not trying to verify the results of Western research, but to control PM2.5 pollutants and prevent and cure the lung cancer caused by it. In China, the classification of PM2.5 pollutants as carcinogens is an important step. In view of the scale of the affected population exposed around the world, it is not too late, and the country can no longer delay, so it needs to act immediately.
