　　The Shanghai environment expert and meteorological expert carry on consult the analysis discovery urgently, the pollution air mass which the north cold air brings are the primary cause, the long distance transportation of pollution group cause the long triangle many cities to occupy the air quality slight pollution the condition. According to the Shanghai environmental monitoring Center predict that the pollution possibly continues to the today and tomorrow. Today’s air pollution index possibly dropped compared to yesterday, air quality still for mild concentration or critical pollution. The experts suggested that heart disease and respiratory disorder patient should reduce the physical exertion and outdoor activities.

　　This morning the temperature plummets to 15℃

　　The early fall season, the north cold air starts to go south unwillingly lonely repeatedly. Yesterday, the whole city highest temperature compared dropped 2℃~3℃ the day before yesterday.

　　Shanghai environmental monitoring Center’s concerned expert pointed out that consecutively for three days of mild concentration . Moreover the index is so high, this year for the first time, under the disadvantageous meteorological condition external agency is the primary factor. According to the meteorological expert analyzed the discovery, the north cold air has brought the pollution air mass, in the cross region transportation process, affected the long triangle and Central China plain air quality . Moreover the pollution tendency did not have to slow down the sign obviously, the pollution possibly continues to 20th, on 21st.

　　Before world abundant, air will be fresher

　　Although the foreign factor is causes this air pollution the important attribute, but controls and reduces the Shanghai local pollution emission to guarantee that the resident breathes to a better air. Otherwise, in the external pollution and this locality pollute under the double whammies will bring the worse air pollution.

　　It is reported that is alive Bo Qian, the Shanghai environmental protection department will develop to raise the dust pollution special rectification and vehicle to limit the line and gas station oil gas recycling and region air pollution union prevention and many other measures, guaranteed welcomes the world abundantly in World Expo has the good ambient air quality.
