To illuminate the air pollution situation of the tourist city of Qinhuangdao, the atmospheric pollutants were measured from autumn 2009 to summer 2010. The results showed that the mean average concentration of NO, NO2, SO2, O3 and PM10 during the observation period reached (18 +/- 18), (45 +/- 18), (42 +/- 46), (44 +/- 25) and (128 +/- 77) microg x m(-3), respectively. The particulate matter pollution was serious, and the rate of the annual mean value exceeded the National Ambient Air Quality Standard II by 28%. The average daily concentration and average max hourly O3 concentration were (64 +/- 21)microg x m(-3) and (126 +/- 42) microg x m(-3) in summer, and the air masses from the southern ocean aggravated the O3 pollution. The concentrations of NO(x) SO2 and PM10 in the heating period were 1.5, 4.9 and 1.5 times more than those in the period without heating and the daily average concentration of SO2 and PM10 exceeded the National Ambient Air Quality Standard II by 53% and 11% in the heating period, respectively. The superimposition effect of regional transport in the Beijing-Tianjin-Hebei region and industrial area surrounding the Bohai Bay and local harbor emission led to an increase of 17% (NO(x)), 27% (SO2) and 12% (PM10), resulting in average concentrations of up to (100 +/- 49), (110 +/- 84) and (215 +/- 108) microg x m(-3) in winter. The winds from northern inland and southern ocean can effectively remove the air pollutants.
为了解秦皇岛这座旅游城市的空气污染状况，于2009年秋季至2010年夏季对大气污染物进行了测量。结果表明，观测期间NO、NO₂、SO₂、O₃和PM₁₀的平均浓度分别达到(18±18)、(45±18)、(42±46)、(44±25)和(128±77)μg·m⁻³。颗粒物污染严重，年平均值超标率比国家环境空气质量二级标准高出28%。夏季O₃日均浓度和小时平均最大浓度分别为(64±21)μg·m⁻³和(126±42)μg·m⁻³，来自南部海洋的气团加剧了O₃污染。供暖期NOₓ、SO₂和PM₁₀的浓度分别是非供暖期的1.5倍、4.9倍和1.5倍，供暖期SO₂和PM₁₀的日均浓度分别比国家环境空气质量二级标准超标53%和11%。京津冀地区区域传输与环渤海湾周边工业区及当地港口排放的叠加效应导致冬季NOₓ增加17%、SO₂增加27%、PM₁₀增加12%，平均浓度分别高达(100±49)、(110±84)和(215±108)μg·m⁻³。来自北部内陆和南部海洋的风能够有效去除空气污染物。
