Several flights were cancelled or delayed in China on Friday because of record levels of pollution that covered the city of Shanghai in smog. This prompted the officials to issue highest level of health warning.
This comes as an embarrassment to China, especially at a time when the country is trying to make Shanghai a global business hub at par with those of London, Hong Kong and New York by the year 2020.
On Friday afternoon, the Shanghai government issued the severest health warning as the pollution index of the city ranged between 23 and 31 times the levels that have been recommended by International Health Officials.
According to the officials, it is unfit for an individual to live in such an environment that is so badly covered with polluted air. The country has made several efforts to fight pollution over the last few years but has not been able to make enough progress. The noxious haze was caused by several factors like industrial pollution, auto emissions trapped by windless weather, cold, etc.
Above 300 levels are hazardous. The World Health Organization recommends that not more than daily level of 20 be recorded in any city.
