at least one recent scientific study has shown that the city can, under the right conditions, “form its own smog”.
The study by Hong Kong and Macau air scientists argued that a rapid build-up of particulate matter in the air – a key component of smog – was possible even in the absence of northerly winds that can transport pollutants from afar.
Deposits on plastic bottles may seem a jolly nice idea to many of us - could make a huge difference in Hong Kong, where we buy and throw away maybe 10 million bottles per day - close to 4 billion per year!

Bloomberg article notes Hong Kong sets a few records, but now - after being run by Donald Tsang - also ranks as the most polluted international financial center.. From article:
Although I'm new here, there's a book project they may be interesting. I've copied the text of the flyer below. (Yes, I am currently interning with Project Kaisei, so if I sound like I'm advertising, I apologize.)
Environmental protection officials in the Hong Kong Special Administrative Region and neighboring Guangdong Province said on Monday they are confident of achieving their targets to reduce air pollution by 55 percent from 1997 levels within the next three years.
Airborne particulates have been in the news in Hong Kong again, as the air is so thick with them that even clear skies are whitish rather than blue (hah! - so much for the government's Action Blue Sky Campaign - launched w fanfare; seems to have vanished amidst the smog); and HK Chief Executive Donald Tsang expressed the view that while they do impact visibility, the particulates may not affect human health!
Possible ways to clean indoor air a little.
