探究“三手烟”的警示
1月6日北京（新华网）——你或许了解二手烟的危害，但根据援引周二媒体的关于儿科的一项研究，专家警告说，三手烟同样有害。
三手烟就是烟熄灭后仍在空气中的烟雾的残留污染，研究人员说，这种有毒烟尘虽沉积于物体表面但仍可通过空气弥散。
Massachusetts General的研究人员进行了这项研究。
研究显示：“儿童对三手烟特别容易暴露，因为他们在周围呼吸攀爬和玩耍，容易接触和误食表面的污染。”
三手烟的残留物中包括重金属、致癌物质和放射性物质，都对孩子产生危害。
芝加哥市呼吸系统健康协会的主席和首席执行官Joel Africk声称，此项儿科研究并非要求禁止在私人住宅吸烟的立法，而是提醒每一位吸烟者和非吸烟者。
