Tennis player Justin Henin-Hardenne is worried about air pollution at the Olympics, because she’s already left a Chinese tennis tournment due to complications from poor air quality and asthma.

“I have had asthma for a few months now and I felt very bad in New York at the end of the tournament so I was really concerned about Beijing,” the Belgian told a news conference in Madrid on Monday.

Henin said had to withdraw from the China Open in Beijing in September because of her asthma.

“I had to go back and see a specialist to start other treatments but I’m feeling better now. I was pretty disappointed because I wanted to play the tournament and get used to the conditions.”

Henin is still hopeful that Beijing’s air will improve and she wil be able to defend the gold medal she won in the 2004 Olympics.
