- Abstract:
-
To understand atmospheric pollution levels and their temporal variation in Luoyang, the concentrations of PM10, SO2 and NO2 in that city were measured continuously by the monitoring equipments from January, 2014 to December, 2016. The results showed that the primary pollutant was PM10, the annual average concentrations were (119.4 ±64.5) μg/m3, (124.4 ±68.1) μg/m3 and (129.0 ±91.2) μg/m3 from 2014 to 2016, respectively. Based on the National Environmental Air Quality Standard of China, all the levels of PM10 during the three years exceeded the secondary grade; sequentially, NO2 was a bit outside the range of the secondary grade, while SO2 was not over the secondary grade. The monthly variations of average concentrations of three pollutants were similar, and their trends appeared U-shape. The three pollutant concentrations were the highest in summer and the lowest in winter. Gradually, annual average concentrations of PM10 and NO2 were both rising while annual average concentration of SO2 was reducing year by year. Pearson analysis indicated that air pollutants were significantly correlated with wind speed, air pressure, air temperature and vapor pressure, and weakly correlated with average relative humidity. It is not a single role that various meteorological factors have the influence on the air pollutant variation, but the combination of those meteorological factors do.
