在海里撒尿没问题吧?

Is it OK to Pee in the Ocean?

《化学反应》 美国化学会出品
So it’s summer
夏日炎炎
and of course you’re heading out to the beach.
当然要去海滩玩耍
You’re splashing around in the waves from the ocean
当你在海浪里扑腾的时候
when you realize…
突然意识到
you may have drank far too much water.
可能喝水喝得太多太多了
The boardwalk is so far away
想上岸 沙滩离得太远
and your feet will get all sandy
脚上也会沾满沙子
so why not just go in the ocean, right?
你想 那干脆在海里撒尿吧
Does your conscious kick in at this point
这时候蹦出这种想法
and make you feel guilty?
会让你感到内疚吗?
Well. It shouldn’t.
其实 不需要内疚
It’s our mission to make you know it’s
我们的任务就是让你了解
absolutely okay to go in the ocean.
在海里撒尿是完全可以的
Here’s why:
原因如下:
First off, urine is mostly water.
第一 尿液的成分大部分都是水
The average human’s urine
一般人类尿液里面
is more than 95 percent water.
含有超过95%的水
It also has between one to two grams
每升尿液中还含有一至二克
per liter of sodium and chloride ions.
钠离子和氯离子
Guess what’s in sea water?
猜海水里有什么?
The ocean is about 96.5 percent H-2-Oh
海水中大约含有96.5%的水
and has a higher concentration
并且含有比尿液浓度更高的
of sodium and chloride than urine.
钠离子和氯离子
Urine and sea water also contain small amounts of potassium.
尿液和海水中也含有少量的钾
So far so good.
目前并没有不妥
Second, urea is the main waste product in our urine.
第二 尿素是尿液中的主要代谢废物
As our bodies break down proteins in food,
当身体分解食物中的蛋白质时
urea is the leftover compound
尿素这种残留物
that gets rid of excess nitrogen in our bodies.
帮我们排出体内多余的氮元素
The amount of urea we release in our urine is
恕我直言 尿液中的尿素量
just, pardon the expression, a drop in the ocean.
跟海水比起来就如同沧海一粟
The volume of the Atlantic ocean
大西洋的水量约为
is about 350 quintillion liters,
3.5万亿亿升
that’s 350 and eighteen zeros.
也就是350后面接18个零
If every person on Earth peed
如果地球上每个人都将
the average amount of pee containing the average amount of urea into the Atlantic,
含有平均尿素量的平均尿液量排到大西洋中
there would be just 60 parts per TRILLION
尿素的含量也只占海水的
of urea in the ocean.
一万亿分之六十
That’s nothing guys
那算不了什么 伙计们
Plus, urea contains a lot of nitrogen,
另外 尿素中含有许多氮
which converts to ammonium in water,
氮在水中可以转变成铵
which feeds ocean plant life.
从而养活海底植物
So no issue there guys.
这也不是问题
We’re still good.
在海里撒尿仍无碍
Finally, forgetting all the fancy math,
最后 忘掉所有复杂的数字
every animal in the ocean… pees in the ocean.
每只海洋动物……都会尿在海里
The fin whale lets out about 970 liters of urine A DAY.
长须鲸一天 就会排出约970升的尿液
That’s more than 250 gallons!
超过250加仑!
So if they’re not harming things,
如果这些无害
you certainly aren’t as well.
你的尿液也肯定无害
So there you go.
所以放心吧
Feel free to pee in the ocean
尽情地在海里撒尿
and go back to worrying about more important things
去担心更重要的事情吧
like that shark that’s right behind you.
比如就在你身后的鲨鱼
OH! And we have to mention this:
对了 我必须提醒一下
peeing in the ocean is totally fine.
在大海里撒尿是完全可以的
But DON’T pee in protected areas
但是不要在保护区撒尿
like reefs,or smaller bodies of water, especially swimming pools.
如暗礁区或较小的水域 特别是游泳池
