Effects Of Air Pollution On Public Health In Huzhou, Zhejiang Province

With the continuous development and progress of science and technology, the rapid growth of population in promoting our production level, promote the development of economy and improve living standards at the same time, also caused great damage to the environment, environmental pollution problem is increasingly serious, environmental costs also increase rapidly. Especially in the urban air pollution problems such as the fog, to our physical and mental health and social stability caused serious damage. At present, the people of all countries to city attaches great importance to are backed by the problem of pollution.Based on the analysis of the main atmospheric pollutants such as SO2, NO2 and PM10 of relevant features in the huzhou city, and its damage to people, on the basis of long-term trends, according to the control "week effect" and meteorological factors in multiple factors, such as air pollution and human health of huzhou exposure - reaction relationship is analyzed, and the use of time sequence semiparametric generalized additive model (GAM), age, gender, and disease types of model is established, the public health caused by the loss of air pollution in huzhou city has carried on the quantitative assessment of the situation. The results for the local government, to build health is sensitive to atmospheric pollution early warning system, and the corresponding measures and the protection of vulnerable groups to work with the corresponding theoreticalAt the same time, the research results also show that atmospheric pollutants SO2 and PM10 concentration during the study period in Huzhou city, generally showed a downward trend year by year, and the bright warm period is lower than the heating period, the summer and fall below the winter and spring. Peak appeared in December next year in May, suggesting that PM10 mainly comes from the spring dust storms and winter coal-fired heating effect. Winter SO2 concentration is relatively high, presenting a typical U change trend, which suggests that the influence of SO2 come mainly from coal to keep warm in winter. And the concentration of NO2 change is relatively small, in both the seasonal and annual change or interannual variations, basically characterized by the heating period is lower than the bright warm period. Relevant data show that when the concentration of SO2, NO2 and PM10 increases, the respiratory system disease of fuzhou residents admissions risk also increases accordingly. The above three kinds of air pollutant concentration increase 10mg/m3, all kinds of respiratory disease, the number of hospital risk change is as follows: the respiratory system disease of the whole population growth of 0.7%,0.5% and 3.4% respectively; URTI all population growth in 1.3%,0.7% and 7.1% respectively; Pneumonia of the whole population growth are 1.6%,1.0% and 1.6% respectively; COPD of the whole population growth of 2.9%,0.3% and 15.9% respectively (note:the influence of PM10 all people with COPD lack of statistical significance). In the aspect of gender, the female is affected by the atmospheric pollution bigger than men. At the age level, in view of the disease, COPD affected obviously by less than 65 people aged is bigger than the influence of more than 65 year old, for URTI and pneumonia disease, more than 65 people aged suffer much more obviously. Huzhou city, at the same time, we also found that atmospheric pollution to a certain extent, also affect the residents of disease of heart head blood-vessel, admissions. Each increased when the concentration of SO2, NO2 and PM10 10mg/m3, its all kinds of people, admissions effect is as follows: the growth of the disease of heart head blood-vessel crowd will are 0.4%,0.5% and 0.4% respectively (note:SO2 and NO2 influence cardiovascular and cerebrovascular diseases all people lack of statistical significance). IHD of the whole population growth of 1.3%,1.1% and 3% respectively (note:the influence of NO2 on the people of IHD all lack of statistical significance). High blood pressure, all people will be increased by 0.8%,1.8% and 0.8% respectively; Whole stroke population growth of 2.1%,1.3% and 10.5% respectively. IHD, for more than 65 year old people are influenced by the larger, and for high blood pressure and stroke disease, less than 65 year old suffered harm bigger crowd.This paper, according to a study in fuzhou air pollution to a certain extent, the harm to the health of people, people suffering from respiratory and cardiovascular disease in hospital number increased with the increase of air pollutant concentration corresponding to ascend, and in the disease type, gender, and age levels showed different degrees of difference.
