A report says air quality in Beijing has improved in the last few years thanks to the implementation of clean air actions.
The report was released by a group of leading British and Chinese scientists.
More than 150 scientists have spent five years conducting one of the largest air pollution field campaigns in Beijing.
The scientists have found that sources of key air pollutants in the city center are much lower than predicted, but concentrations were still relatively high in 2016 and 2017.
Researchers also discovered that cooking oil emissions are a source of potentially hazardous fine particles in Beijing.
The report also says road traffic is not a major source of primary PM2.5, but remains a significant source of Nitrogen oxide.

The top US infectious diseases expert says the nation has not turned the corner yet on the coronavirus pandemic, despite a rise in vaccinations.
Dr. Anthony Fauci says the number of daily infections is still too high in the country to declare victory against the virus.
"We do have a lot of challenges in front of us with regard to the high level of daily infections, yesterday being, 54,974. When you are at that level, I don't think you can declare victory and say you've turn the corner. You've got to continue to do what we're doing, more vaccinations and continue to do public measures until we actually turn the corner."
While daily cases are still high at around 55-thousand, the figure is a significant drop from the 250,000 daily cases at the peak of the winter wave.
So far, more than 2.5 million Americans are getting vaccinated each day.

The head of the International Chamber of Shipping has raised concerns about the impact of the current blockade of the Suez Canal to worldwide trade.
A skyscraper-sized container ship has become wedged across Egypt's Suez Canal and blocked all traffic in the waterway, threatening to disrupt global shipping.
Guy Platten says the Suez Canal is one of the most strategic waterways in the world as it carries about 12 percent of world trade annually.
"We are already seeing evidence that ships are starting to gather at the entrances to the canal at both ends, so that process, that logjam is starting to grow as every hour that passes. So it's a serious incident. It shows you how fragile the global supply chains can be at times."
The Ever Given, a Panama-flagged ship that carries cargo between Asia and Europe, ran aground in the Suez Canal on Tuesday.
