I’m very sorry; I was in too much of a hurry and didn’t pay attention to my wording! :(
It seems there are very few Hyatt guests who meet this standard; let’s keep waiting. I found the following information on other websites: In 2008, the EU issued the Directive on Air Quality and Cleaner Air in Europe, setting a target concentration limit for PM2.5 at 25 μg/m3 by 2010. At the same time, toxic and harmful volatile pollutants such as benzene were specified as pollutant categories, and heavy metal pollutants such as As, Cd, and Ni, which mainly originate from coal combustion and vehicle emissions, were also regulated.
Thank you for your reply! :handshake
