The other problem with most plastics is that there are other molecules in that material-in that base polymer-that are added there to make the plastic flexible or make it really thin, and those things are broadly called " plasticizers."

多数塑料还有另一个问题，在这种基物的材料，还要添加其他分子，让塑料变得柔软或轻薄，这些东西被统称为“增塑剂”。

These chemicals-widely used in the middle decades of the 20th century to manufacture electrical insulation, coolants, sealants and plasticisers-often ended up dumped in lakes, rivers and coastal waters.

在20世纪的几十年，这些化学物质广泛应用于制造电气绝缘物，冷却剂，密封剂增塑剂，它的废物排污于湖泊，河水。

These plasticizers I was talking about are lipophilic, meaning they easily transfer when in contact with fats.

我刚才说的这些增塑剂是亲脂性的，也就是说它们在与脂肪接触时很容易转移。

But then, I have seen at least one paper that found that the cycle of heating and freezing, if you use the same container to do both many times, will also enhance degradation and also enhance those plasticizers leaching out.

但是，我至少看到有一篇论文说过，加热冷冻循环，如果你对同一个容器多次加热冷冻，也会加速它的降解，增加增塑剂的浸出。
