致毒气扩散

展开全文

事情源于当地时间2月3日,在美国俄亥俄州东部邻近宾夕法尼亚州的小镇东巴勒斯坦城,一列诺福克南方火车的约50节车厢脱轨,并引发火灾。

根据当地居民拍摄画面显示,事故现场火光冲天、浓烟弥漫,浓烟甚至能在气象雷达上显示,散到附近小镇。

The train, operated by Norfolk Southern, had been carrying chemicals and combustible materials, with vinyl chloride, a toxic flammable gas, being of most concern to investigators.

这列火车由诺福克南方公司运营,载有化学品和可燃物质,调查人员最担心的是有毒可燃气体氯乙烯。

A huge fire erupted from the derailment, sending thick billowing smoke into the sky and over the town.

火车脱轨后引发了一场巨大的火灾,滚滚浓烟冲入天空,包围了附件小镇。

那么,氯乙烯是什么?为什么会让大家如此担心?

Vinyl chloride is also a carcinogen that’s been linked to increased risk of liver cancer. The Centers for Disease Control and Prevention warns that breathing vinyl chloride over long periods “may be connected” to brain cancer, lung cancers and some cancers of the blood.

氯乙烯也是一种致癌物质,会增加患肝癌的风险。美国疾病控制与预防中心警告称,长期吸入氯乙烯“可能”会引发脑癌、肺癌和某些血癌。

“Short-term exposure to high levels can cause dizziness, drowsiness, fatigue and headaches,” Maria Doa, the senior director for chemicals policy at the Environmental Defense Fund, said in an email.

“短期吸入高浓度的氯乙烯会导致头晕、嗜睡、疲劳和头痛,”环境保护基金会化学品政策高级主管玛丽亚·多阿在电子邮件中说。

事故发生后,东巴勒斯坦城当局3日深夜在社交媒体发文,对事发地点周围1英里(约合1.6公里)范围内居民发布撤离令,并开放了当地高中和社区中心作为避难所,同时建议疏散区域外的居民避免外出。

6日,工作人员对有毒气体进行所谓“受控释放”,也就是将车上的氯乙烯排放并燃烧。

The authorities’ decision to burn vinyl chloride from the five tanker cars was rooted in concern that they could explode and send shrapnel and other debris into nearby neighborhoods.

当局决定焚烧这五辆油罐车中的氯乙烯,是因为担心会发生爆炸,碎片飞射,危害附近的社区。
