The air pollution in the Pearl River Delta (PRD) is more harmful to residents’ health than Beijing’s due to the higher level of nitrogenous organic compounds, Hong Kong website House News reported Thursday.

Wu Dui, an expert at the China Academy of Meteorological Sciences said due to the different kinds of contaminants, PM 2.5 particles in PRD contained more nitrogenous organic compounds than in eastern and northern parts of China.

The nitrogenous organic compounds, the main components of photochemical smog, are mainly emitted by shoe and cosmetics factories.

Wu mentioned that the problem was discovered a decade ago, but was ignored at that time. He said the pollution would be worse from July to September when the sunlight was too strong to prevent the air circulating well. Cutting down emissions is the only way to solve the problem, Wu said.
