PM2.5是指大气中直径小于或等于2.5微米的颗粒物,也称为可入肺颗粒物。它的直径还不到人的头发丝粗细的1/20。虽然PM2.5只是地球大气成分中含量很少的组分,但它对空气质量和能见度等有重要的影响。与较粗的大气颗粒物相比,PM2.5粒径小,富含大量的有毒、有害物质且在大气中的停留时间长、输送距离远,因而对人体健康和大气环境质量的影响更大。2012年2月,国务院同意发布新修订的《环境空气质量标准》增加了PM2.5监测指标。

(2)某检测点的部分群众在看到PM2.5超标后,便到市政府门口拉横幅、堵门、喧闹,严重影响了政府正常的工作秩序。还造成社会秩序的一定混乱。

(6分)假如让你去做这些 * * 群众的说服工作,请你运用所学知识,写出你的劝说提纲。

(3)(8分)请你就如何控制PM2.5,请分别从法律、科技的角度向市政府各提一条可行性建议并说明其理论依据。
