As of today, the devastating explosion caused by the Sinopec Huanghua Oil Pipeline in Huangdao District, Qingdao City, continues to leave a deep impact on the hearts of many. The sight of roads torn apart and streets turned into rivers still lingers in people's minds, echoing the tragedy of an innocent disaster. This incident bears a painful resemblance to the Dalian pipeline explosion in 2010, where harmful gases released during the accident posed serious threats to the local environment and ecosystems.
According to the Propaganda Department of the Working Committee of the Qingdao Economic and Technological Development Zone (Huangdao District), approximately 18,000 residents from 12 communities have been evacuated. At Dexian Road Primary School, located in the western part of the area, students were provided with masks as a precaution. Despite these efforts, smoke from the fire in Huangdao continues to spread toward the city center, raising concerns among the public.
The Qingdao Environmental Protection Bureau reported that at the northwest corner of the intersection of Wuhu Island Street and Huaihe Road, the concentration of non-methane hydrocarbons was measured at 2 mg/m³, well below the national standard of 4 mg/m³. At another monitoring point near the intersection of Huaihe Road and Penghudao Street, the level was recorded at 1 mg/m³. These readings indicate that current air quality remains within safe limits.
In a recent statement posted on its official Weibo account, the Qingdao Municipal Environmental Protection Bureau released a preliminary report on the oil pipeline leak incident. According to the monitoring data, the levels of non-methane hydrocarbons downwind have not yet exceeded the safety threshold. Non-methane total hydrocarbons refer to all volatile hydrocarbons except methane. When their concentration rises beyond certain levels, they can cause direct harm to human health, irritate the eyes, respiratory tract, and skin, and under specific conditions, contribute to the formation of photochemical smog, which poses additional risks to both the environment and public health.
Experts from the EPA, interviewed by China Labor Safety Net, emphasized that the explosion released various irritating gases that could be carried by the wind. These substances may cause varying degrees of irritation and damage, primarily affecting the eyes, nose, throat, and skin. While most effects are localized, prolonged exposure can lead to systemic reactions.
In response to the situation, experts recommend that local residents take extra precautions. They advise wearing protective masks, using skin ointments for added protection, and avoiding unnecessary outdoor activities until the air quality improves.
