一、问题背景近年来,随着经济发展不断加快,工业化、城市化不断增速,工厂排放的污染性气体及可吸入颗粒物不断增多,空气污染也越发严重。由于气象条件不同,空气污染物扩散的快慢与污染程度也会有所差异。为了增强保护环境意识,本课题围绕各种天气现象对城市空气污染的影响进行了探究,从身边的实例了解目前严峻的环境形势,进而从小事做起,热爱环境、爱护自然。二、探究目标探究目标。搜集处在不同天气条件下的城市污染状况
First, the problem background In recent years, with the accelerating economic development, industrialization, urbanization continues to grow, factories emit pollutant gases and respirable particulate matter continues to increase, air pollution is also more and more serious. Due to different weather conditions, the spread of air pollutants and pollution levels will vary. In order to enhance the awareness of environmental protection, the subject explores the impact of various weather phenomena on urban air pollution. From the examples around us, we understand the current harsh environmental situation, and then start from a small matter, love the environment and take good care of nature. Second, explore the target to explore the target. Collect urban pollution in different weather conditions
