如果条例从PM10改为PM2.5测量,新西兰的Blenhim可能无法达到新的空气质量标准。 Blenheim, New Zealand, may fail new air quality standards if regulations shift from PM10 to PM2.5 measurements.

2024年,新西兰布伦海姆达到了空气质量标准,但环境部提议的修改可能使其不符合标准。 In 2024, Blenheim, New Zealand, met air quality standards, but changes proposed by the Ministry for the Environment could make it noncompliant. 目前,Blenhim监测PM10,限制为每立方米50微克,每年允许一次超额。 Currently, Blenheim monitors PM10, with a limit of 50 micrograms per cubic meter, allowing one exceedance yearly. 如果按提议向PM2.5标准转变,布伦海姆将记录21次超额,达不到新的限额。 If the standard shifts to PM2.5, as proposed, Blenheim would have recorded 21 exceedances, failing to meet new limits. 这一变化可能需要采取额外的空中管理措施。 This change could require additional air management measures.
