Beijing (CNS) -- Beijing's air quality has declined in the first quarter of this year, reaching its worst in January, the local municipal environmental protection bureau said on Monday.
Chen Tian, head of the bureau, said in a live broadcast that the levels of PM10 and nitrogen dioxide increased by 20 percent in the first quarter compared with the same period last year. The levels increased by 47 percent in January.
He attributed it to motor vehicles and home heating with coal, saying the city's emissions have exceeded its environmental capacity. Oxynitride emitted by 5.25 million automobiles in Beijing accounts for more than 56 percent of the total oxynitride emissions in the city, Chen added.
Chen also said the government will put more effort into lowering tailpipe emissions, as only about a hundred thousand vehicles currently meet the Beijing V standard.
Construction of two heating plants in the northwest and northeast parts of the city will be accelerated to reduce individual coal-fired heating, Chen added.
