Turns out, that's not chlorine you can smell at all... There's more to that chlorine smell than meets the nose. Chlorine is one of those smells that's instantly recognisable. Just a whiff of it can conjure up fond (or not so) childhood memories of swimming lessons, galas and days out.
事实证明，你闻到的根本不是氯。你闻到的气味不止是氯这么简单。氯气的辨识度很高。一丢丢氯气就能召唤出孩时上游泳课、盛会和出去浪的那些日子的美好回忆。
A sudden blast of chlorine may also remind you that you should probably give your house a quick clean, but it remains that chlorine and swimming pools are forever linked in our minds and noses. But that strong chemical smell isn't all it's cracked up to be... A strong chlorine smell doesn't indicate high levels of chlorine at all, according to the National Swimming Pool Foundation ( nspf.org ).
突然闻到氯可能会让你想起，也许该打扫屋子了，但我们的大脑和鼻子却一直将氯和游泳池联系在一起。但这种浓烈的化学气味并没有人们所说的那么好。浓烈的氯气味儿并不意味着氯含量很高，国家游泳池基金会表示（nspf.org）。
In fact, it indicates some real nasties lurking in the water. Experts at the Water Quality and Health Council, U.S. Centers for Disease Control and Prevention and that NSPF said properly treated swimming pools do not have a strong chemical smell.
事实上，这表明水中潜伏着一些脏东西。水质与健康委员会、美国疾病预防与控制中心、国家游泳池基金会的专家表示，经恰当处理的游泳池并不会散发出强烈的化学气味。
Instead, when chlorine in pool water combines with urine, feces, sweat, and dirt from swimmers' bodies, the mixture produces chemical irritants called chloramines. It's the chloramines that give off that familiar odour, which in fact USE UP chlorine and cause eyes to sting and go red. All of which means there's not much in the way of protection from germs.
相反，当泳池中的氯与游泳者的尿液、粪便、汗水和污垢混合时，混合物会产生化学刺激物，即氯胺。散发出这种气味的物质是氯胺，实际上会导致眼睛刺痛、红肿。这些都意味着它几乎无法保护我们不受细菌感染。
Does this change how you feel about swimming pools? "It's understandable why most people think that a chemical smell means there is too much chlorine in the pool, but the truth could be the opposite," said Chris Wiant, Chair of the Water Quality and Health Council. "To help prevent chloramines from forming where you swim, shower before swimming and take little swimmers on regular bathroom breaks."
这会改变你对泳池的看法吗？"大人数人觉得这种化学气味代表着泳池里的氯过多，这是可以理解的，但真相却可能恰恰相反，"水质与健康委员会的主席Chris Wiant说道。"为了防止泳池中氯胺的形成，你可以在游泳前淋浴，带小孩子在常规的浴室休息。"
