北美作业代写 呼吸系统疾病

许多人患有呼吸系统疾病，如鼻炎、鼻子过敏、哮喘等，因为他们在童年时期暴露在空气污染的地区。根据一本名为《空气污染对儿童健康和发展的影响》的书，空气污染中的颗粒物、二氧化氮和臭氧会影响儿童的呼吸系统。这本书收集了关于空气污染对儿童呼吸系统影响的各种研究。颗粒物对哮喘患者的影响更为严重。本研究的一部分进一步表明，它会对肺功能造成明显的不利影响。长期暴露于二氧化氮影响患病率、哮喘发病率、过敏性鼻炎或过敏性湿疹。“四分之三的研究显示与支气管炎和咳嗽有关，而三分之二的研究显示肺功能明显下降。”臭氧影响肺的功能。一项大型研究表明，当哮喘儿童生活在高臭氧浓度地区，发病率增加。与交通有关的空气污染物影响哮喘和花粉热的流行和发病率。(Kuna-Dibbert Krzyżanowski &施耐德,2005)因此,根据这本书,我们得到一个结论,许多颗粒物等污染物,二氧化氮,臭氧等引起的呼吸道感染。此外，由于空气污染，许多儿童患有呼吸道疾病。空气污染影响急性呼吸道感染。空气污染与哮喘相关的发病率和死亡率有关。大量证据表明，与空气污染相关的发病率和死亡率与呼吸道感染呈正相关。在欧洲，2001年有四分之一的儿童死于急性呼吸道感染。约翰斯顿(Chatterjee Johnston)做了一项研究，希望了解空气污染与儿童急性呼吸道感染的风险和严重程度之间的关系。他们的研究指出，空气污染中的PM10、PM2.5、二氧化氮、二氧化硫和臭氧会增加儿童的上呼吸道和下呼吸道症状。据调查，研究人员称，当污染物减少时，儿童的呼吸健康可以得到改善.

北美作业代写 呼吸系统疾病

Many people suffer respiratory diseases, such as rhinitis, nose allergies, asthma, and so on, because they were exposed to the air polluted area during their childhood. According to a book called Effect of Air Pollution on Children’s Health and Development, particulate matter, nitrogen dioxide, and ozone in air pollution affect children’s respiratory systems. This book collected a variety of studies about the effects of air pollution on children’s respiratory system. Particulate matter causes more serious effects on asthmatics. A part of this research further showed it causes significant disadvantage effects on lung function. Long-term exposure to nitrogen dioxide affects prevalence, the incidence of asthma, allergic rhinitis or atopic eczema. “Three out of four studies showed an association with bronchitis and cough while two out of three showed significant reductions in lung function. Ozone affects the functions of the lungs. One large study showed when asthmatic children who live in high ozone concentration areas and increase the rate of incidence. Traffic-related air pollutants affect the prevalence and incidence of asthma and hay fever. (Krzyżanowski, Kuna-Dibbert, & Schneider,2005) Therefore, according to this book, we get a conclusion that many pollutants such as particulate matter, nitrogen dioxide, ozone, and so on cause respiratory infection. Furthermore, many children suffer respiratory disease because of air pollution.Air pollution affects acute respiratory infections. Air pollution has a connection with asthma-related morbidity and mortality. Much evidence proves that the morbidity and mortality related to air pollution have a positive connection with the respiratory infection. In Europe, there were a quarter of children who were killed by acute respiratory infections in 2001. Chauhan, Chatterjee Johnston made a study that wanted to know the relationship between air pollution and the risk and severity of acute respiratory infections in children. Their study pointed out PM10, PM2.5, nitrogen dioxide, sulfur dioxide and ozone in air pollution increased upper and lower respiratory symptoms in children. According to the survey, the researcher claimed children’s respiratory health can be improved when the pollutants decrease.
