Abstract
In order to understand the rural environment air quality of North He'nan Province,54 villages of 5 types in 6 provinces and municipalities in North He'nan Province were selected to monitor the environment air quality for a total of 1,440 days from 2015 to 2018.The monitoring data of main pollution factors SO2,NO2 and PM10 was analyzed.The results showed that the number of days for the rural environment air quality to reach the standard in northern He'nan province was 1156 days,the rate of compliance was 80.3%,and the main factors that exceeded the standard were PM10 and NO2.The mass concentrations of SO2 and NO2 in rural environment air were low;although the mass concentration of PM10 was relatively high,it generally showed a downward trend; the non-compliance rate of the environment air quality of the 5 types of villages in order from large to small was:industrial type>ecological type>tourism type >planting type>breeding type; the worst air pollution was in the first quarter,exceeding the standard,the main pollution factor was PM10; the better air quality was that of Puyang city,followed by Hebi city and Xinxiang city,and the worse were that of Jiaozuo city,Jiyuan city and Anyang city.Various means can be taken to reduce the pressure on the prevention and control of environmental air pollution in rural areas by appropriately increasing regional monitoring points,conducting source analysis research on major factor PM10 and actively developing online monitoring.
