Shijiazhuang (CNS) Voluptuous sirens.-- Chemical compounds found in China's smog are similar to those in the photochemical smog that affected Los Angeles in the 1940s and '50s, according to a study conducted by the Chinese Academy of Sciences.

The academy detected a large amount of nitrogen-containing organic compounds in the recent air pollution that shrouded Beijing, Tianjin and Hebei province. The chemicals are believed to be the major components of the smog that killed more than 800 people in L.A. over six decades ago.

Since the density of the nitrogen-containing organic compounds in China's smog has not been measured, we can't tell how harmful it is to human health, said Xie Jianfeng, an official from the environmental monitoring center in Hebei province, on Monday.

The cause for the prolonged pollution is a direct consequence of both man-made emissions and disruption of the natural ecological balance, he added.

The Chinese Academy of Sciences says the prolonged smog was caused by a combination of intensive coal burning, car emissions, cooking pollutants and a particular weather pattern that creates an inversion layer over low-lying cities.
