生态环境部两项废气标准首发，5月1日实施！

Core Viewpoint - The Ministry of Ecology and Environment has released two new air pollution measurement standards, HJ 1457-2026 and HJ 1458-2026, which will be implemented on May 1, 2026, marking a significant step in air quality monitoring and regulation in China [1][2]. Group 1: Measurement Standards - HJ 1457-2026 introduces a portable beta-ray method for measuring low-concentration particulate matter from fixed pollution sources, applicable to various industries excluding lead-zinc smelting and battery manufacturing [3][4]. - The detection limit for this method is 0.3 mg/m³, with a measurement lower limit of 1.2 mg/m³ when sampling at standard conditions [4]. - HJ 1458-2026 outlines a method for measuring 30 types of volatile organic compounds (VOCs) using bag sampling and portable gas chromatography-mass spectrometry [6][7]. - The detection limits for VOCs vary based on sampling conditions, ranging from 0.05 mg/m³ to 7 mg/m³, with measurement lower limits from 0.2 mg/m³ to 28 mg/m³ [7]. Group 2: Policy and Market Implications - The new standards are driven by the need for enhanced low-emission regulations under the "14th Five-Year Plan," necessitating frequent monitoring of low-concentration particulate matter in industries such as power generation, steel, and cement [8]. - The introduction of HJ 1457-2026 will create demand for portable beta-ray particulate monitoring devices, as it provides a legal method for enforcement and self-monitoring [8]. - HJ 1458-2026 will push companies in sectors like chemicals and electronics to adopt portable GC-MS and bag sampling systems, increasing the demand for emergency monitoring services from third-party testing organizations [8]. - Both standards support rapid on-site monitoring, aligning with the ecological environment department's needs for mobile enforcement and real-time tracking, thus fostering growth in integrated solutions for portable monitoring equipment and smart regulatory platforms [8].
