“Asbestos was banned in the U.S. In 1979. The twin towers were built a couple years before so I’m not surprised.”一位专门室空气的教授解释完，转向陈立，“No offence， but I believe asbestos is still wildly used in China. If we inspect this building， it will be very likely to find asbestos in ducts， insutors， and other building materials.” （译：国1979年开始禁止使用石棉材料。双塔的建成比那早几年，所以不奇怪。没有冒犯的意思，但是据我所知石棉材料在中国仍然广泛应用。如果我们检查这间屋，很有可能会在、隔层和其它建筑材料中发现石棉。）

陶郁笑：“Your house is new. I bet you told Carol the story so she allows you to smoke at home.” （译：你家房

老说：“I’ve seen studies showing if you leave in an asbestos containing house but you don’t smoke， or the opposite way， the risk of getting lung cancer wouldn’t be a lot higher than normal. But if you smoke and live in an asbestos containing house at the same time， the moster would come to you.”（译：我看过一些研究，如果你烟但不住在有石棉的房里，或者相反，患癌症的风险并不比正常况很多。但如果你既烟又住在有石棉的屋里，那“怪兽”就会找到你了。）

“Thought asbestos had been banned for decades in the US.” 陶郁说，“It is the most common cause of lung cancer. When were the twin towers built？” （译：我以为国几十年前就禁止（在建筑材料中使用）石棉了。它是最常见的导致肺癌的原因。双塔是什么时候建的？）

s， concrete， anhydrite， metal， and even asbestos.” （译：那些灰尘就是在一天累积起来的。我们了一个短期污染风险分析，在灰尘里发现各成分，玻璃纤维、泥（粉末）、脱硫酸钙（国建筑墙面的主要成分）、金属（粉末）、甚至还有石棉。）
