德里首次进行云种试验,使用化学品增加降雨量,减少空气污染,但效力和安全性仍不确定。 Delhi's first cloud-seeding trial used chemicals to boost rainfall and reduce air pollution, but effectiveness and safety remain uncertain.

德里进行了首次云种试验,通过增加降雨量、使用碘化银或盐基化学品刺激云层的雨滴形成来防止严重空气污染。 Delhi conducted its first cloud-seeding trial to combat severe air pollution by enhancing rainfall, using silver iodide or salt-based chemicals to stimulate raindrop formation in clouds. 该技术是1940年代开发的,旨在从大气中清除污染物,尽管关于其有效性的全球证据仍然有限。 The technique, developed in the 1940s, aims to wash pollutants from the atmosphere, though global evidence of its effectiveness remains limited. 环境关切包括潜在的碘化银毒性和干冰产生的温室气体排放。 Environmental concerns include potential silver iodide toxicity and greenhouse gas emissions from dry ice. 试验突出显示,目前正在努力评估云种在城市空气质量改善中的作用,并进行安全和准确所需的认真规划和监测。 The trial highlights ongoing efforts to assess cloud seeding’s role in urban air quality improvement, with careful planning and monitoring required for safety and accuracy.
