Abstract

Analysis of summertime temperature characteristics and ozone exposure indexes were carried out for eight locations in Poland for a 15-year period (1997–2011). The number of days with the maximum temperature exceeding 25°C and 30°C was calculated for each year. The analysis covered the 8-hour running average and daily maximum of near surface ozone concentrations. Also, the accumulated exposure when ozone concentrations were above 120 μg/m3 (AOT60) was calculated as a diagnostic indicator of adverse health effects for each year. Although high ozone concentrations are associated with hot temperatures, the exposure to values higher than 120 μg /m3 is correlated with the length of the hot weather period rather than with the occurrence of days with extremely high temperatures. In most cases the elevated ozone concentrations occurred during days when the maximum temperature was higher than 24°C. Episodes of very high ozone concentrations, exceeding 180 μg /m3, were not associated with heat wave periods at analysed locations.
在波兰高温事件背景下的15年地表臭氧污染分析
对波兰8个地点15年(1997-2011)的夏季温度特征和臭氧暴露指数进行了分析。计算每年最高气温超过25℃和30℃的天数。分析涵盖近地表臭氧浓度的8小时平均值和日最大值。此外,还计算了臭氧浓度超过120 μg/m3 (AOT60)时的累积暴露量,作为每年不良健康影响的诊断指标。虽然高臭氧浓度与高温有关,但高于120 μg /m3的暴露量与炎热天气期的长度相关,而与极端高温天数的发生无关。在大多数情况下,臭氧浓度升高发生在最高温度高于24°C的日子里。在所分析的地点,臭氧浓度超过180 μg /m3的极高浓度与热浪期无关。
