As far as the impact of air pollutants on human health being concerned, ozone is one of the main pollutants in atmosphere. In particular, the ground level ozone is responsible for a variety of adverse effects on both human being and plant life. To protect the humankind from such adverse health effects, early information and precautions of high ozone level need to be supplied in times. In this study, statistical characteristics of ground level ozone is analyzed according to the field monitoring data in mixed residential, commercial and industrial areas, e.g., Tsuen Wan area in Hong Kong. The study deals with the characteristics of hourly and daily mean ozone levels under different climatic conditions such as temperature, solar radiation, wind speed, and other pollutant concentration levels. The study aims to investigate the importance of meteorological factors and their impact on relevant pollutant concentration levels from chemical aspect. Further, reasons causing the spatial and temporal variations of ozone levels are discussed. All these results will provide a physical basis for accurately predicting ozone concentration in extensive, future research.
就空气污染物对人类健康的影响而言，臭氧是大气中的主要污染物之一。特别是地面臭氧会对人类和植物生命造成各种不利影响。为了保护人类免受此类不良健康影响，需要及时提供高臭氧水平的早期信息和预防措施。在本研究中，根据香港荃湾等混合住宅、商业和工业区的现场监测数据，分析了地面臭氧的统计特征。该研究探讨了在不同气候条件下，如温度、太阳辐射、风速和其他污染物浓度水平下，每小时和每日平均臭氧水平的特征。该研究旨在从化学角度研究气象因素的重要性及其对相关污染物浓度水平的影响。此外，还讨论了导致臭氧水平时空变化的原因。所有这些结果将为在广泛的未来研究中准确预测臭氧浓度提供物理基础。
