16 yesterday, the latest forecast of the environmental protection department release, many users on the microblogging question, from yesterday until next month on the 1st, the capital's heavily polluted air for 4 days, why not start red warning.
It is reported that, according to the 2015 revised release of "Beijing air heavy pollution emergency plan" heavy air pollution warning is divided into four levels, before the start of the yellow warning for predicting heavy air pollution will last two days (48 hours); orange alert for predicting heavy air pollution will last three days (72 hours); the red warning for predicting heavy air pollution will last for more than 3 days (72 hours).
correspond to different colors of warning, measures are also different, including health protection measures, the proposed contingency measures and compulsory emergency measures in three categories.

After the emergency plan amendments, according to the environmental protection department statistics, found that in accordance with this new standard, three times last year (a total of about 10 days) in line with published red alert condition.
However, regardless of the emergency plan prior to its amendment or amendment, Beijing has never been started red alert.
One environmental expert said yesterday, for more than three days even more long-term air quality forecasting and early warning, is a world problem, so this requires relevant departments to improve their forecasting and warning capabilities. In addition, he believes the current presentation area into a piece of pollution pollution characteristics, regional level and scale of pollution forecasting and early warning and urgent need for emergency measures, so as to achieve a more efficient and rapid reduction of pollution effects.
