Smoggy weather has become common in China. But these days, air pollution levels in the north eastern city of Harbin surpassed the previous record levels.
The city was essentially shut down after PM2. 5, fine Particulate(微粒物) pollution that is considered hazardous(有害的) . reached levels of 1000 micrograms per cubic meter-40 times the safety level remended by the World Health Organization. Schools, motorways and an airport were closed on Tuesday as visibility in some areas of the city dropped to less than 10 meters.
Photos from Harbin showed residents covering their mouths with masks and scarves, and moving like ghostly shadows through the fog. Cars and motorcycles are moving slowly as traffic came to a standstill with traffic lights barely visible. .
Just days previously , the World Health Organization's International Agency for Research on Cancer (IARC) classified air pollution as a carcinogen(致癌物) . It stated that there is " sufficient evidence" that exposure to outdoor air pollution causes lung cancer and also linked it with an increased risk of bladder cancer. It's said that exposure has increased significantly particularly in " rapidly industrial countries with large populations".
"The air we breathe has become polluted with a mixture of cancer-causing substances" , Dr Kurt Straif , head of the IARC said in a press released. "We now know that outdoor air pollution is not only a major risk to health in general, but also a leading environmental cause of cancer deaths. "
