        “大气十条”实施以来，全国城市PM_2.5浓度呈下降趋势，预期能够实现国家规定的2017年空气质量改善目标。若按现有力度措施，北京市2017年PM_2.5浓度达到年均值60 μg/m³左右的目标难以实现，同时臭氧（O₃）污染迅速抬头。未来两年必须下决心采取超常规措施破解北京大气污染防治中的若干难点问题，才能突破大气污染治理瓶颈，达到预定目标。

        In most Chinese cities, fine particulate matter (PM_2.5) concentration has decreased after implementation of Air Pollution Prevention and Control Action Plan in the past three years, and the goals of overall national air quality improvement listed in the plan is expected to be achieved by 2017. However, the specific goal of that PM_2.5 annual concentration in Beijing shall be controlled below 60 micrograms per cubic meter by 2017 is difficult to be accomplished. Meanwhile, ozone (O₃) pollution is emerging quickly in Beijing. Regarding the present situation in air pollution in Beijing, a number of extraordinary measures of air pollution prevention and control must be carried out immediately during the next two years.
