关于空气质量的英语专业术语

关于空气质量的英语专业术语

这两天大家肯定都很关注空气质量状况的播报，或许你会奇怪空气质量指数究竟是依据哪些污染物算出来的？

各种等级的污染对我们有哪些危害？

下面就来为大家科普下这些基础学问吧：

【关于空气质量的术语】

环境空气ambientair

指人群、植物、动物和建筑物所暴露的室外空气

空气质量指数airqualityindex（AQI）

定量描述空气质量状况的无量纲指数。

空气质量分指数individualairqualityindex（IAQI）

单项污染物的空气质量指数。

首要污染物primarypollutant

AQI大于50时IAQI最大的空气污染物。

超标污染物non-attainmentpollutant

浓度超过国家环境空气质量二级标准的污染物，即IAQI大于100的污染物。

总悬浮颗粒物totalsuspendedparticle（TSP）

指环境空气中空气动力学当量直径小于等于100μm的颗粒物。

颗粒物（粒径小于等于10μm）particulatematter（PM10）

指环境空气中空气动力学当量直径小于等于10μm的颗粒物，也称可吸入颗粒物。

颗粒物（粒径小于等于2.5μm）particulatematter（PM2.5）

指环境空气中空气动力学当量直径小于等于2.5μm的颗粒物，也称细颗粒物。

*此前我们国家采纳的空气质量标准是API（AirPollutionIndex），也就是空气污染指数；但在2021年2月后进行了修订，改为AQI，最重要的一个改变就是加入了PM2.5的监测。

【AQI基于哪些空气污染物】

TheAQIlevelisbasedonthelevelof6atmosphericpollutants:

①二氧化硫：

sulfurdioxide（SO2）

②二氧化氮：

nitrogendioxide（NO2）

③PM10：

suspendedparticulatessmallerthan10μminaerodynamicdiameter

④一氧化碳：

carbonmonoxide（CO）

⑤臭氧：

ozone（O3）

⑥PM2.5：

suspendedparticulatessmallerthan2.5μminaerodynamicdiameter

【空气质量指数及对健康的危害】

空气质量指数（AQI）空气质量指数类别（AirPollutionLevel）表示颜色（Colors）对健康影响状况（HealthImplications）建议实行的措施（HealthMessages）英文综述

0-50优（Good）绿色（Green）空气质量令人满足，基本无空气污染各类人群可正常活动Nohealthimplications.Enjoyyourusualoutdooractivities.

51-100良（Moderate）黄色（Yellow）空气质量可接受，但某些污染物可能对极少数特别敏感人群健康有较弱影响极少数特别敏感人群应削减户外活动Membersofsensitivegroupsshouldreduceoutdooractivities.

101-150轻度污染（LightlyPolluted）橙色（Orange）易感人群症状有轻度加剧，健康人群消失刺激症状儿童、老年人及心脏病、呼吸系统疾病患者应削减长时间、高强度的户外熬炼Slightirritationsmayoccur.Children,eldersandpeoplewithheartorbreathingproblemsshouldreducestrenuousoutdooractivities.

151-200中度污染（ModeratelyPolluted）红色（Red）进一步加剧易感人群症状，可能对健康人群心脏、呼吸系统有影响儿童、老年人及心脏病、呼吸系统疾病患者避开长时间、高强度的户外锻练，一般人群适量削减户外运动Slightirritationsmayoccur.Children,eldersandpeoplewithheartorbreathingproblemsshouldrestrictstrenuousoutdooractivities.

201-300重度污染（HeavilyPolluted）紫色（Purple）心脏病和肺病患者症状显著加剧，运动耐受力降低，健康人群普遍消失症状儿童、老年人和心脏病、肺病患者应停留在室内，停止户外运动，一般人群削减户外运动Healthypeoplewillbenoticeablyaffected.Children,eldersandpeoplewithheartorbreathingproblemsshouldremainindoors.Healthyindividualsshouldreduceoutdooractivities.

300严峻污染（SeverelyPolluted）褐红色（Maroon）健康人群运动耐受力降低，有明显剧烈症状，提前消失某些疾病儿童、老年人和病人应当留在室内，避开体力消耗，一般人群应避开户外活动Healthypeoplewillexperiencereducedenduranceinactivities.Theremaybestrongirritationsandsymptomsandmaytriggerotherillnesses.Children,eldersandthesickshouldremainindoorsandavoidexercise.Healthyindividualsshouldavoidoutdooractivities.
