So in 1926, President Calvin Coolidge used the help of chemists to make these already toxic alcohols even more dangerous, particularly by adding methanol.

所以在 1926 年，卡尔文·柯立芝总统在化学家的帮助下，让这些已经有毒的酒精更加危险，特别是通过添加甲醇的方式。

Unfortunately, ethanol and toxic alcohol metabolites like acetaldehyde also pass freely through the placenta, but the fetal liver doesn't have the necessary enzymes to metabolize them, so they build up inside the fetus really fast.

不幸的是，乙醇及有毒的酒精代谢产物，如乙醛，也可自由通过胎盘，而胎儿的肝脏却没有分解这些物质所必需的酶，因此它们可以在胎儿体内快速积聚。
