环保部:“中国北方人因空气污染减寿5.5年”不可信

       对美国近日发布的一份研究报告所称“中国北方人因空气污染比南方人减寿5.5年”,中国环境保护部科技标准司副司长刘志全7月10日回应,上述结论缺乏实证,有失偏颇,“没有大量样本得出这个结论不可信”。

       美国《纽约时报》等媒体8日报道称,一项最新研究显示,居住在淮河以北的五亿中国人由于室外空气污染将总共丧失25亿年的预期寿命,即中国北方人的预期寿命平均比南方人少5.5年,原因是北方普遍使用煤炭取暖导致空气污染,对人体心肺功能造成破坏性影响。

国际开源期刊polymers约稿通知 (IF: 1.687)

Dear Colleagues,

Functional polymers possess combined physical, chemical and mechanical properties and functionalities taking advantage of their conductive, optical, electronic and biomedical features. Some functional polymers also reveal stimuli responsive properties that are subject to change upon exposure to external stimuli such as temperature, pH, and light. Perturbation of local environment can lead to change in polymer conformation, structure, and aggregated states that render them be used as smart materials. Polymer colloids allow further expansion of applications of functional polymers as they can be easily processed and adopted for conjugation with a variety of biomolecules. Hierarchical self-assemblies comprised of polymer colloids show applications as photonic materials with tunability simply by changing the size of the colloids. Recent studies also suggest that nanoscaled polymer colloids have similar application potentials as semiconducting quantum dots. In recent years, polymer colloids have emerged as one of the most promising materials due to their size and morphology -dependent properties, and the feasibility for chemical modification that allows exploration of emergent phenomena and commercial applications.
