Smog formation possible in Hong Kong

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.


CY Leung and Hong Kong air pollution

After lambasting Donald Tsang for not combating, and even defending, air pollution - can see how CY Leung administration performs in this regard. Perhaps promising signs to start with; this from SCM Post Lai See:

Old waste incinerator technology will threaten health of HK people

Professor Tony Hedley is an expert on Hong Kong air pollution and health; recently retired from being Chair Professor of Community Medicine at the University of Hong Kong. Here's excerpt of an email he sent regarding Hong Kong government's plans to build a mega-incinerator on artificial island by Shek Kwu Chau:


Plan for incinerator island by Shek Kwu Chau environmentally unacceptable

The choice of building an incinerator on a specially constructed artificial island by Shek Kwu Chau is not justified on any scientific basis, and is environmentally unacceptable.

More people die when Hong Kong air dirtier

Press Release from Clean Air Network:

A new study unveiled today by HKU’s Department of Community Medicine demonstrates that there is a direct link between visibility and the health impacts of air pollution.
Until now, scientists have had to rely on epidemiological research (illness in communities), clinical observation (sick people needing care), and molecular biology, to determine the health effects of air pollution. Now, however, environmentalists and public health experts have a new way to measure the potential damage from air pollution.
The study, which was conducted by the University of Hong Kong’s School of Public Health, shows that, for every loss of 6.5 kilometers of visibility, there is a 1.13 percent increase in all natural causes of death, accounting for about 450 deaths per year.
