请将下面这段话翻译成英文：
三手烟是指在吸烟几小时或几天之后仍然残留在地毯、衣物以及其他物品中的烟污染。据研究，许多人，尤其是烟民，都不知道三手烟会危害人们的健康。在接受调查的1500名烟民和非烟民中，绝大部分人都认同二手烟的危害。但当他们被问到是否知晓“吸入前一天有人吸烟的屋子里的空气会危害你的健康”时，只有65%的非烟民和43%的烟民回答是肯定的。
参考译文：
Third-hand smoke refers to the tobacco smoke contamination that lingers on carpets, clothes and other materials hours or days after smoking. According to a study, a large number of people,particularly smokers, have no idea that the third-hand smoke is a health hazard for people. Of the 1,500 smokers and nonsmokers surveyed,the vast majority agree that second-hand smoke is harmful. But when asked whether they agreed with the statement, "Breathing air in a room where people smoked yesterday can harm your health," only 65% of nonsmokers and 43% of smokers gave the affirmative answer.
