Core Viewpoint - The automatic monitoring of pollution sources has established a large system, but issues such as unclear responsibility, irregular equipment maintenance, inconsistent data quality, and frequent data falsification persist, undermining the industry's image and reducing the effectiveness of fund utilization. The Jiangxi Province has proactively introduced the "Regulations on the Management of Automatic Monitoring Data for Pollution Sources" to address these challenges [1][2]. Group 1: Regulations and Responsibilities - The regulations clearly define that the polluting units are the responsible entities for automatic monitoring, mandating them to install, use, and maintain monitoring equipment legally, ensuring the normal operation and accuracy of monitoring data [1]. - The regulations include detailed anti-fraud provisions, listing four types of illegal activities and establishing penalties for both the units and responsible individuals, including dual fines and a five-year employment ban [1]. Group 2: Data Application and Industry Impact - The automatic monitoring technology has matured, yet biases regarding its reliability hinder investment in monitoring equipment. The recognition of the value of automatic monitoring by enterprises is crucial for its widespread application [2]. - The regulations state that marked automatic monitoring data can serve as evidence for pollution permits, waste treatment fee calculations, environmental statistics, and environmental protection tax assessments, which can incentivize polluting units to acknowledge the importance of automatic monitoring [2]. - A robust automatic monitoring system requires not only advanced technology and well-maintained equipment but also legal support to ensure its effectiveness and promote a positive feedback loop in the industry [2].

央广网北京7月20日消息（总台中国之声记者刘梦雅 蔡薇）据中央广播电视总台中国之声《新闻纵 横》报道，生态环境部发布的最新空气质量预报显示，7月下半月，全国大部空气质量以优良至轻度污 染为主。京津冀及周边地区中南部、长三角、汾渭平原和成都平原个别城市可能出现臭氧中度污染。 臭氧污染指的是近地面对流层臭氧浓度过高，对人体健康和生态环境造成危害的一种现象。近地面 的臭氧主要来自于机动车尾气、石油化工废气等污染源排放，这其中含有大量氮氧化物和挥发性有机物 等前体物，它们在强烈太阳紫外线的作用下发生光化学反应后，就会产生大量臭氧，从而造成臭氧污 染。高温的夏季是臭氧污染高发的季节，今年夏天臭氧污染的形势如何？人们应该怎样注意防范、降低 危害？当前又有哪些新技术、新手段来助力臭氧污染监测与治理？ 臭氧是氧气的同素异形体，在常温下是一种有特殊臭味的淡蓝色气体，这种气体有好有坏，到底 是"地球卫士"还是"隐形杀手"，这取决于它们到底在哪里。中国环境保护组织公众环境研究中心主任马 军介绍，约有90%的臭氧在10千米高空的平流层，是自然产生的，可以形成地球的保护伞，保护地球上 的生物免于紫外线的辐射伤害，这些臭氧就是有益的。与 ...
