Isaac Wirgin, at NYU, and Mark Hahn, at Woods Hole, have been studying PCB-resistant fish, to see how they do it.

在伍兹霍尔研究所，艾萨克的Wirgin和纽约大学的Hahn，研究了耐PCB鱼类，了解到他们是如何做到的。

Dr Hahn is looking at a different animal, the killifish (pictured), in New Bedford harbour, Massachusetts, which was polluted by other producers.

而Hahn博士研究位于马萨诸塞州新贝德福德港口的鳉鱼（如图），这部分流域遭受到其他生产企业的PCB污染。

Dr Hahn has, however, found nine places along the amino-acid chain of killifish AHR where the link in the chain varies between individuals.

但沿AHR的氨基酸链上有9个部位的链接存在个体变异。

He described it as a " very historic breakthrough" on the basis of a study the statistics of which the head of the FDA, Stephen Hahn, got publicly and spectacularly wrong.

他称这是一个基于一项研究的“非常具有历史意义的突破”，FDA局长史蒂芬·哈恩公开了这项研究的数据，这些数据错得离谱。
