"The smell comes after midnight and it makes me cough a lot and I can't sleep," she said.
Zhao said she posted her suffering on the online forum of the Tiantongyuan community, and many others had also complained.
The environmental department of Changping district received Zhao's complaint, and told the Global Times that it had pinpointed the Luxin Asphalt Factory, which is only two kilometers away from Zhao's compound and works at night, as the possible pollution source.
The department said Monday that it has warned the factory not to pollute the air. But Zhao says this has barely worked.
"In the first month the air quality did improve, but then it worsened," she said.
Tiantongyuan is the largest residential compound in Asia, and the population had reached 400,000 by June 2012, according to news portal qianlong.com.
The residential area was built on a former landfill, and from the 1950s on, household garbage was buried in its eastern section, while medical waste was buried in the western section, the Beijing News reported.
