The draft version of a new set of policies to control fine particle pollution is open for public comment until March 4, according to the Environmental Protection Ministry.

It consists of suggestions to manage PM2.5 pollution - particles smaller than 2.5 microns in diameter that can go deep into the lungs - from all kinds of sources, including industry, agriculture and automobiles.

"It is more like a guide to all levels of government bodies on the detailed measures, technologies and management approaches to deal with PM2.5," Feng Bo, an official from the ministry's science, technology and standards department, told China Daily.
