受8月連續強降雨影響,卑南溪溪水暴漲,部分河段既有水覆蓋及導水土堤遭洪水沖刷受損,河床裸露面積增加。為迎戰秋冬東北季風可能帶來的河川揚塵,台東縣政府於降雨趨緩、確認現地作業安全後,立即投入人力及重型機具展開修復,目前環保局施作維護之水覆蓋區域,修復進度已達7成以上。
縣政府表示,8月豪雨造成台東大橋至出海口等河段水覆蓋明顯受損,環保局隨即辦理現地勘查及機具調度,依河床裸露情形及揚塵風險,優先針對高風險區域進行導水、築堤及水覆蓋修復,並視河床水文及天候條件持續擴大改善範圍。

縣府指出,卑南溪河床變動快速,水覆蓋設施容易受到颱風、豪雨及溪水暴漲影響,因此揚塵防制並非一次性的工作,而是必須隨河床及水文條件持續調整。目前逐漸進入東北季風好發時期,縣府將持續掌握氣象、風速風向、河床裸露及水覆蓋狀況,滾動調整修復區位及施工量能。
臺東縣環保局指出,依歷年監測及防制經驗分析,當水覆蓋修復程度達7成,在風速達4.6公尺/秒以上時,河川揚塵發生機率可由約5成降至約2成。因此此次搶在東北季風影響加劇前加速恢復水覆蓋,不只是修復受損設施,更重要的是提前降低裸露河床受強風吹襲所造成的揚塵風險。

A two-year-old seal named Nana swam 200km back to Dachangshan Island in Liaoning province after being released into the ocean on September 7, marking its second return to a human-inhabited area, according to Science Education Times.

Shanxi Province has officially issued the "15th Five-Year Plan for the Construction of Beautiful Shanxi", which deploys 17 indicators and 58 tasks around the four major areas of ecological environment quality, pollution reduction and carbon reduction, ecological protection and risk prevention and control, aiming to promote a fundamental improvement in the ecological environment and build a solid ecological barrier in the middle reaches of the Yellow River.

On September 24, the Shanxi Provincial Department of Ecology and Environment announced at a press conference that the province’s comprehensive ambient air quality index dropped by 28% during the “14th Five-Year Plan” period, and 11 districts and cities have completely dropped out of the bottom ten of 168 key cities in the country. During the "15th Five-Year Plan" period, Shanxi will promote the transformation of industry, energy, and transportation structures and strive to achieve a fundamental improvement in the quality of the ecological environment.
During field scientific research and monitoring, staff at the Wufeng Houhe National Nature Reserve in Hubei captured for the first time high-definition field images of forest musk deer, a national first-level protected wild animal, showing clear images of it walking through mountain forests and shrubs.

The Environmental Protection Bureau of the Taoyuan City Government promotes "Smoke-free Purdue" during the Ghost Festival this year, calling on industrial areas, large temples and communities to respond. The event attracted more than 45,000 participants, reduced air pollutants and achieved 4.89 metric tons of carbon reduction, and combined environmental protection with traditional folk customs.

All 108 schools in Serian, Sarawak, were ordered to close on Thursday after the air pollutant index breached 200, reaching the very unhealthy category.
