That's the term being used to describe the invisible yet toxic brew of gases and particles clinging to smokers' hair and clothing, not to mention cushions and carpeting, that lingers long after second-hand smoke has cleared from a room. The residue includes heavy metals, carcinogens and even radioactive materials that young children can get on their hands and ingest, especially if they're crawling or playing on the floor。 吸烟的父母常常会开窗或打开电扇,以此为他们的孩子净化空气,不过专家们最近发现了另一种与香烟有关的对儿童健康的威胁,而且更难对付——三手烟。
所谓“三手烟”是指房间内的“二手烟”清除许久之后,仍残留在坐垫、地毯甚或吸烟者头发和衣物上看不见的气体和颗粒的有毒混合物。残留物包含重金属、致癌物,甚至辐射物质,它们很容易沾在婴幼儿的手上并被吃到嘴里,尤其是当小孩子在地板上爬或玩耍时。
