China’s Ministry of Environmental Protection has drafted definitions for the conditions that qualify a day as having haze pollution. It says a haze pollution day occurs when the average concentration of PM2.5 is above 75 micrograms per cubic meter and visibility is less than 5 km for more than six consecutive hours due to an increasing concentration of fine particulate matter in the air.

The Environmental Protection Department of the HKSAR Government has recently released the 2012 air pollutant emission inventory. Just as with the prior three years, ship emissions remain Hong Kong’s largest source of sulphur dioxide (SO2), respirable suspended particulates (RSP or PM10) and nitrogen oxides (NOx).

Finally, some data. A couple of weeks ago Civic Exchange and two Hong Kong universities released a report detailing the extent of emissions from ships in the Pearl River Delta region, and their public health impact. It’s a groundbreaking study. Using 2008 data, researchers from HKUST did a ship emissions inventory of vessels activity across the PRD. They then calculated the dispersion of the pollutants, which showed that Shenzhen and Hong Kong have the most ship emissions, ahead of other coastal PRD regions such as Zhongshan and Dongguan, and outer PRD regions, like Foshan and Huizhou.
