Special trees help clear Guangzhou's air

GUANGZHOU: Experts are working in this southern city to develop tree species that could make a major contribution to the battle against pollution.

A total of 30 species, including camphor trees, are currently being tested in terms of their ability to resist air pollution at the Huadu Liuxiwan Agriculture and Forest Ecology and Technology Center.

"These special trees, which will be used in the city's urban greening projects, will play growing role in cutting urban air pollution," said Zhang Weiqiang, a researcher with the Guangdong Forest Research Institute (GFRI).
