|airborne contaminant;大氣污染物
大氣污染物(Atmospheric Pollutant) 是指存在于地球大氣層中,對自然環境、生态系統或人類健康産生有害影響的物質或能量形式。這類污染物可通過自然過程(如火山噴發、沙塵暴)或人類活動(如工業排放、交通尾氣)釋放到空氣中,其濃度超過環境本底水平或安全阈值時即構成污染。
主要特征與類型
大氣污染物通常以氣态、顆粒物或氣溶膠形态存在。常見類型包括:
環境影響與健康危害
治理與監管
國際公約如《蒙特利爾議定書》和《巴黎協定》推動污染物協同減排,各國通過排放标準(如中國《大氣污染防治法》)、清潔能源轉型及實時監測網絡(如AQI指數)實施管控。
參考資料來源
Atmospheric pollutant(大氣污染物)指存在于大氣中,對生态環境、人類健康或氣候系統造成負面影響的物質。以下是詳細解釋:
基本定義
大氣污染物是自然或人為釋放到大氣中的有害物質,當其濃度超過環境容量時,會破壞生态平衡或威脅人類健康。例如懸浮顆粒物(PM₂.₅、PM₁₀)、硫氧化物(SOₓ)、氮氧化物(NOₓ)等。
來源
顆粒物(Particulate Matter, PM)
如PM₂.₅(直徑≤2.5微米)可深入肺部,引發呼吸系統疾病和心血管問題。
氣體污染物
其他污染物
包括一氧化碳(CO)、重金屬(如鉛、汞)及持久性有機污染物(POPs)。
健康與生态影響
控制措施
如需進一步了解具體污染物标準或案例,可參考權威環境機構報告(如聯合國環境規劃署)。
