新德里空气污染严重,外交官分享中国经验
Huan Qiu Shi Bao· 2025-12-18 22:54
接下来几天里,宇静逐步介绍中国如何一步步治理空气污染。报道称,这些帖文概述了一套综合治理模 式,包括严格的机动车排放标准、关停高污染工厂、减少煤炭、推广清洁能源以及区域协同规划。 印媒提到,中国外交官的建议之一是对新德里机动车实施严格的排放管控,采用较高标准,例如与欧6 标准类似的中国"国六"标准,该标准针对的是氮氧化物和其他污染物的排放。 【环球时报特约记者 任重】近日印度首都新德里空气污染情况严峻,中国驻印度大使馆一名发言人在 社交平台分享了中国治理大气污染的经验,收获印度网民关注。 据印度"oneindia"网站18日报道,中国驻印度大使馆发言人宇静15日在社交平台发帖说:"中印两国都深 知在快速城市化进程中应对空气污染的挑战。虽然问题依然复杂,但中国过去十年持之以恒的努力已带 来显著改善。" "oneindia"网站提到,尽管新德里此前已进行过交通管制试验,但汽车尾气仍然是空气污染的主要来源 之一。印度已要求所有2020年4月1日之后生产的车辆必须符合BS-VI排放标准,但老旧车辆仍在道路上 行驶。 宇静的帖文下方有不少印度网民留言表示支持和感谢。有网民说:"我曾在污染最严重的时候去过北 京,也曾在奥 ...
越南首都深陷重度雾霾 政府敦促工厂减产
Yang Shi Xin Wen· 2025-12-13 04:53
河内民众:"这样的空气对老年人的健康影响很大。我们已经进入了全球空气污染最严重的城市行列。 如果能想办法把空气污染水平降下来,让人民的生活好一些,那就再好不过了。" (文章来源:央视新闻) 连日来,越南首都河内持续受重度雾霾困扰。 为了应对污染,越南卫生部已于本周早些时候敦促电力、钢铁和化工厂削减产量。河内也将从2026年年 中开始在市中心部分区域实施汽油摩托车禁令,并将在此后逐步把禁令扩大至燃油汽车。 空气污染信息应用程序AirVisual的数据显示,12月11日中午,河内的空气质量指数(AQI)达到243, 使其位列全球空气污染最严重城市第四位。如果换算成PM2.5浓度,河内的空气污染水平可能是世界卫 生组织建议的5微克/立方米标准的50倍之多。而本周,这座城市还多次登上全球空气污染最严重城市榜 首。 另据报道,摩托车是河内居民的主要交通工具,该市拥有约700万辆摩托车和100多万辆汽车。 ...
阿联酋媒体:印度治理空气污染可向中国学三个经验
Huan Qiu Shi Bao· 2025-12-01 10:03
Core Viewpoint - India is facing severe air pollution issues, particularly in northern cities like Delhi and Mumbai, and lacks the political will to treat this as a public health emergency, which exacerbates the situation. The country can learn valuable lessons from China's approach to tackling air pollution, particularly in promoting electric vehicles and public transportation electrification [1][2]. Group 1: Key Lessons from China - India should develop a long-term comprehensive action plan rather than reactive measures that only respond to deteriorating air quality. This requires better coordination between state and central governments [2]. - More efforts are needed to control vehicle emissions and promote clean fuels, as the public transportation system in most Indian cities does not meet expectations. Increased funding is necessary to address these gaps [2]. - Accurate data is crucial for building public trust. The Delhi government's poor handling of pollution data has eroded citizen confidence, making it difficult to trust that effective measures will be taken to address the crisis [2]. Group 2: Challenges in Implementation - India's progress in addressing air pollution is hindered by weak enforcement and competing priorities, unlike China's strict regulations and promotion of clean energy [2]. - The existing system in India is flawed, with loose assessments and ineffective enforcement. Stronger actions are required to achieve significant improvements similar to those seen in China [3].

印度要重见蓝天,中国经验是“良方”
Huan Qiu Shi Bao· 2025-11-18 00:36
Core Insights - The article discusses the severe air pollution issues faced by India, particularly in Delhi, and highlights China's willingness to share its air quality management experiences to help India overcome these challenges [1][2]. Group 1: Air Pollution in India - India is currently experiencing a dual crisis of aerosol pollution leading to short-term cooling and a health crisis, compounded by the risk of accelerated future warming [2]. - The industrial emissions, urban traffic, dust, and crop burning in the Indo-Gangetic Plain contribute to some of the worst air pollution globally [2]. - Predictions indicate that India's warming rate may double in the coming decades, leading to extreme heat, disrupted monsoons, and agricultural interruptions [2]. Group 2: China's Air Quality Management Experience - China's air quality management began in earnest in 2013, resulting in a 57% reduction in PM2.5 average concentration and a 92% decrease in heavy pollution days from 2013 to 2022, while GDP grew by 69% [1]. - The Chinese approach emphasizes prioritizing the closure of inefficient pollution sources and strict emission standards to quickly address residents' health issues [2]. - China has demonstrated that pollution control and carbon reduction can be synergistic, providing a model for other developing countries [3]. Group 3: Global Implications and Cooperation - The article suggests that China's experience serves as a guide for other developing nations facing similar development and environmental challenges [3]. - China's commitment to sharing renewable energy technology and financial support with countries like India contrasts with the politicalization of climate issues by some nations [3]. - The overarching theme is that pollution management and climate change response should be integrated into a single governance framework, emphasizing a human-centered and systematic approach [3].
印度新德里多次人工降雨失败引争议
Huan Qiu Shi Bao· 2025-11-03 22:49
在这场"人工降雨争议"背景下,印度理工学院德里分校发布了一份研究报告。研究团队分析了2011年至2021年的气候数据,发现新德里冬季气候 干燥、湿度极低,不具备持续进行人工增雨的条件。即使在理论上实现降雨,其效果也只能维持1至3天,空气污染水平很快会反弹。 【环球时报报道 记者 苑基荣】印度首都新德里近日展开多次人工降雨试验,以缓解持续恶化的冬季空气污染问题,但因成效有限引发争议。 报告还强调,人工降雨既成本高昂,又存在科学不确定性,对污染源并无实质作用,不应作为新德里治理空气污染的主要手段。报告参与者、印 度理工学院德里分校教授加尼表示,印度政府应集中力量推动清洁燃料使用、改善废弃物管理,并严格监管排放,"除非控制住污染源,否则污染 物浓度不会真正降低"。 综合《印度斯坦时报》《印度快报》等媒体11月1日报道,新德里政府与印度理工学院坎普尔分校展开合作,于10月下旬动用两架飞机在市区上空 释放含有碘化银和氯化钠颗粒的焰弹,试图触发降雨。然而,由于云层稀薄、湿度不足,降雨量极少,计划中的后续试验也被迫中止。 印媒称,新德里每年冬季的雾霾问题尤为严重,冷空气使农田焚烧、工厂和汽车排放物滞留在地表。近日,该市PM ...

第一作者兼通讯作者,我国学者发表Science论文,揭示我国城市空气污染的独特化学机制
生物世界· 2025-09-01 10:30
Core Viewpoint - Air pollution is a global environmental issue with significant impacts on air quality, climate, ecosystems, and human health. China's severe smog pollution, characterized by high PM2.5 concentrations, has shown improvement since 2013 due to regulatory measures [2][3]. Group 1 - The unique formation mechanism of smog in China involves both high-intensity primary pollutant emissions and efficient secondary transformation processes [2][3]. - The current stage in China is marked by a mix of agricultural and industrial societies, leading to high emissions of secondary aerosol precursors from various sources, including ammonia from agricultural activities and nitrogen oxides from industrial activities [3][4]. - A recent review published in the journal Science highlights the complex interactions of multiple atmospheric factors contributing to the unique formation mechanism of secondary organic aerosols (SOA) in urban China [4][10]. Group 2 - Despite significant progress in environmental pollution control over the past decade, uncertainties remain regarding the precursors, formation processes, and impacts of SOA on radiation budgets and human health in Chinese cities [6][9]. - The substantial decrease in PM2.5 concentrations in urban China has led to a significant increase in ground-level ozone concentrations, which facilitates SOA formation [6][9]. - Understanding the sensitivity of ozone-nitrogen oxides-volatile organic compounds in urban areas is crucial for developing economically effective strategies to control precursors that lead to high concentrations of both SOA and ozone [6][9]. Group 3 - The study identifies that high atmospheric oxidation capacity in winter results from various factors, including high concentrations of gas-phase nitrous acid photolysis and nitrogen oxides participating in olefin ozonolysis [7][9]. - The increase in nitrate proportions has also enhanced the liquid water content of aerosols, further promoting the generation of liquid-phase SOA [7][9]. - Future research should focus on exploring unknown oxidation pathways, characterizing precursors and multi-generation oxidation products at the molecular level, and understanding the corresponding generation and aging mechanisms [7][9]. Group 4 - The paper summarizes the scientific status of SOA formation in urban China, emphasizing the dominant role of anthropogenic precursors, the main mechanisms of SOA formation, and the importance of multi-pollutant and multiphase processes in SOA evolution [9][10]. - This research deepens the understanding of the formation mechanisms of haze pollution in China and provides a reference for global atmospheric pollution studies, offering important scientific basis for future air pollution control and policy-making [10].
