在中国,城市笼罩在浓重雾霾里成了司空见惯的情景。2017年冬天,有关北京“空气末日”(airpocalypse)的报道占据了全球媒体的头条,在中国国内也引发了不满和争论。但在本周,中国东北部城市哈尔滨的大气污染状况则刷新了之前北京高污染水平的记录。
世界卫生组织的国际癌症研究机构将大气污染归为致癌物。据称,有“充分证据”证实,暴露在大气污染下的户外会导致肺癌,而且还会有增加患膀胱癌的风险。
中国雾霾已经广泛地成为呼吸道疾病的诱因,而且据新华社报道,医学专家发出警告称,在哈尔滨高危雾霾之后,需要相关疾病治疗的人数将会大增。
Cityscapes shrouded in thick smog have become a common scene in China. Last winter, Beijing's 'airpocalypse' garnered headlines worldwide and generated much anger and debate within China. But this week, air pollution levels in the northeastern city of Harbin surpassed the previous record levels in Beijing.
The city was essentially shut down after PM2.5, fine particulate pollution that is considered hazardous, reached levels of 1,000 micrograms per cubic metre – 40 times the safety level recommended by the World Health Organisation. Schools, motorways and an airport were closed on Tuesday as visibility in some areas of the city dropped to less than 10 metres.
