|airborne contaminant;大气污染物
大气污染物（Atmospheric Pollutant） 是指存在于地球大气层中，对自然环境、生态系统或人类健康产生有害影响的物质或能量形式。这类污染物可通过自然过程（如火山喷发、沙尘暴）或人类活动（如工业排放、交通尾气）释放到空气中，其浓度超过环境本底水平或安全阈值时即构成污染。
主要特征与类型
大气污染物通常以气态、颗粒物或气溶胶形态存在。常见类型包括：
环境影响与健康危害
治理与监管
国际公约如《蒙特利尔议定书》和《巴黎协定》推动污染物协同减排，各国通过排放标准（如中国《大气污染防治法》）、清洁能源转型及实时监测网络（如AQI指数）实施管控。
参考资料来源
Atmospheric pollutant（大气污染物）指存在于大气中，对生态环境、人类健康或气候系统造成负面影响的物质。以下是详细解释：
基本定义
大气污染物是自然或人为释放到大气中的有害物质，当其浓度超过环境容量时，会破坏生态平衡或威胁人类健康。例如悬浮颗粒物（PM₂.₅、PM₁₀）、硫氧化物（SOₓ）、氮氧化物（NOₓ）等。
来源
颗粒物（Particulate Matter, PM）
如PM₂.₅（直径≤2.5微米）可深入肺部，引发呼吸系统疾病和心血管问题。
气体污染物
其他污染物
包括一氧化碳（CO）、重金属（如铅、汞）及持久性有机污染物（POPs）。
健康与生态影响
控制措施
如需进一步了解具体污染物标准或案例，可参考权威环境机构报告（如联合国环境规划署）。
