methyl

However, thiomersal, the preservative in some vaccines, contains ethyl mercury not methyl mercury.

然而，在某些疫苗中用作防腐剂的硫柳汞含乙基汞，并非含甲基汞。

Further, ethyl mercury is actively excreted via the gut, unlike methyl mercury, which accumulates in the body.

另外，乙基汞通过肠道被积极排除出去，而不像甲基汞那样在体内积累。

In particular, ethyl mercury decomposes much more quickly than methyl mercury and does not accumulate in the body.

特别是乙基汞的分解速度比甲基汞快很多，并且不会在体内累计。
