Smog is a common sight in Hong Kong, with the amount of polluted days increasing by 28 percent to 303 so far this year. Hong Kongers would be quick to point the finger at Chinese factories across the border. Yet, research is increasingly indicating that the problem is much more localized, coming from emissions produced by shipping. What we know in Hong Kong is that up to 50% of pollution sources come from marine vessels, said Gina McCarthy, administrator at the U.S. Environmental Protection Agency. Smog levels within the city of over 7 million reached hazardous levels earlier this week, with particles in one urban area, Sham Shui Po hitting a PM2.5, hitting 91.7 micrograms per cubic meter of air. Anything above 71 is classified as very dangerous according to the World Health Organization guidelines.
