The organic matter may partially decompose, using up the dissolved oxygen in the sediment.

有机物会局部分解，消耗沉淀里的溶解氧。

David says that dissolved oxygen attaches to the PFAS and breaks it.

大卫说，溶解的氧气会附着在 PFAS 上并将其分解。

They take in water and extract the dissolved oxygen which fuels their cells.

它们吸入海水，然后提取溶解在其中的氧气来让自己的细胞正常运作。

Unable to wash downriver, the nutrients build up while dissolved oxygen in the water decreases.

养分因无法向下游流动而不断累积，同时水中的溶解氧量却在不断减少。

One more detail bears mentioning: that is the warmer water also holds less dissolved oxygen.

水温升高会导致水中的溶解氧含量减少。

Fey said an important finding was that the researchers were able to show such a notable drop in dissolved oxygen levels.

费伊称，研究人员能够证实溶解氧水平的显著下降非常重要。

At the ocean's surface, a small — proportion of gases like oxygen and carbon dioxide dissolve into the water — dissolved oxygen, for example, allows sea creatures to breathe.

在海水表面，有很小一部分的气体，比如氧气和二氧化碳，溶解在海水中 (举个例子，氧的溶解可以让海洋生物呼吸)。

It fully dissolves oxygen from the air, and any solvent or any ion can be dissolved fully.

它能完全溶解空气中的氧气，任何溶剂或任何离子都能被完全溶解。

The dissolved oxygen can then diffuse into the tissues, where it's needed to make ATP.

溶解氧可以扩散到组织中，在组织中生成ATP。

Underwater, fish breathe with gills, which are feathery organs packed with blood vessels that absorb dissolved oxygen from the water.

在水下，鱼用鳃呼吸，鳃是羽毛状的器官，里面布满了吸收水中溶解氧的血管。

You see, the dissolved oxygen diffuses into the plasma first, and then it diffuses into the red blood cells.

你看，溶解氧首先扩散到血浆，然后扩散到红细胞。

In this lesson, we're going to discuss the significance of both hemoglobin and dissolved oxygen in terms of oxygen transport.

在这节课中，我们将讨论血红蛋白和溶解氧在氧传输方面的重要性。

Therefore, while the amount of dissolved oxygen may be low compared to the amount bound to hemoglobin, dissolved oxygen is essential for oxygen transport.

因此，虽然溶解氧的量可能比与血红蛋白结合的量低，但溶解氧对于氧的运输是必不可少的。

However, even the primary source of oxygen that fish get is not from the oxygen in H2O, but from microscopic bubbles of dissolved oxygen in the water.

然而，即使鱼获得氧气的主要来源也不是来自 H2O 中的氧气，而是来自水中溶解氧的微小气泡。
