次の英文を和訳してほしいです。
Methylation is a chemical process in which a methyl(CH3)group is added to an atom or molecule.
The resulting compound does not usually dissolve in water and is more easily absorbed into organisms such as plankton.
Methylmercury is very dangerous because it enters the food chain as soon as it is absorbed into plankton.
Next, it ends up in a fish that eats the contaminated plankton.
After the contaminated fish is eaten by another fish, the methylmercury stays in the surviving fish's flesh, and the cycle may be repeated over and over.
Once the mercury reaches the top of the food chain, for example in a 300-kilogram tuna, it will stay there for the rest of the fish's life.
As a result, people are very worried about the effect of eating fish that are high on the food chain or very old.
These fish may have very high accumulations of mercury, and thus may be dangerous to eat.
Fish that are lower on the food chain, or younger, are seen as safer.
As the article makes clear, an important first step is to discover the exact nature of the ocean's mercury methylation process.
After the process is understood, it may be possible to control it.
Until we can reduce the amount of mercury that accumulates in the ocean, it would be advisable to avoid fish that may be high on mercury, wouldn't it?
