摘要
Based on the conventional meteorological observation data during 1959-2014 and data of lung cancer cases of a third-grade classA tumor hospital in Nanchang City during 1997-2013,the annual variation of haze days in Nanchang City during 1959-2014 and its correlation with the related meteorological factors,as well as the characteristics of different types of lung cancer patients in Nanchang during 1997-2013 were analyzed. A correlation analysis method was used to study the correlation between the number of urban lung cancer patients and the number of haze days and fog days in each month in Nanchang. The lagging period of lung cancer was also discussed. The results show that the number of haze days in Nanchang rose since 1959,which is mainly related to the increase in the emissions of urban pollutants and the decrease of surface wind speed. The average age of female lung cancer was earlier than that of men. The number of men lung cancer patients was significantly larger than that of women. The number of urban lung cancer patients was obviously larger than that in rural areas. Haze had a great impact on the occurrence of lung cancer,with the lagging period of three years. Haze had a greater impact on urban women than urban men. The impact of haze on old people was greater than that of young and middle-aged people.
