The total land area of Macau measured 29.9 km2 at the end of 2011, up by 0.7 percent year-on-year. The population density rose by 1.7 percent to 18,400 people per km2.

In 2011 total rainfall decreased significantly by 37.2 percent year-on-year to 1,363.6 mm; the lowest pH value of rainwater was 3.5 (precipitation with a pH value lower than 5.6 is classified as acid rain).

DSEC further indicated that the quality of potable water from the distribution network and Water Treatment Plants of Macau conformed to the standard, according to the results of the analysis carried out by the Laboratory of the Civic and Municipal Affairs Bureau. The salinity level of potable water was classified as "Low" in 2011.

Well, for those who are not happy here, feel free to leave..., its quite simple actually, just pack and go home. Macau doesn't need expats with their neo-liberal ideas. Go home !

Anti-Expat, i really do not see the logic between poor air quality and the neo-liberal ideas of expats. But then logic and common sense do not exists in Macau, this is another good example!!

Anti-Expat, that we do not like the air quality does not mean we are not happy here...By the way, who developed the Cotai strip? Exactly: expats!

What a load of rubbish. When you can't see Zhuhai from Taipa most days in winter (due to the northerly wind from China), you know this is total propaganda. Let's see how many good days they had by world air quality standards, not those made up by Macao, HK, and China....

Yes, this is all true. The DSEC and the bureaus responsible for that (if there is any) are totally right. We have a fantastic QUALITY OF THE AIR as we all know and can see and breath...
