Condolences to the family and friends of Tsang Kam-yin that passed away today after becoming critically ill while participating in Sunday's marathon (see government press release).

While it is impossible to ascertain the role that the severe pollution levels may have had on Mr. Tsang, the toxic air quality on that day should certainly be seriously considered as a contributor. We await a confirmation or denial of this being a factor in Mr. Tsang's death from the government.

It is very disappointing, that two days after nearly 40,000 citizens undertook strenuous exercise during environmental conditions that were dangerous to health, Hong Kong's Department of Health has issued no notice or recommendations to the community. Shame on you Dr. Lam, please re-read your mission statement.
