  • So it is summer, and of course, of course you're heading up to the beach.

    夏天到了 你一定正準備衝往海邊吧

  • You splash around the waves from the ocean, when you realize

    當你正在海邊踏浪戲水時 會發現…

  • you may have had forge made to drink

    無意間 你喝進了太多水

  • The boardwalk was so far away


  • you feel get little bit sandy.


  • So, why not just go in the ocean, right?


  • Did your conscience taken at this point? And they keep you guilty?

    你的良心是否在此時作祟 罪惡感油然而生?

  • Well, it shouldn't.

    其實 你不用這樣

  • It's our mission to make you note, it's absolutely okay to go in the ocean,

    這次的任務就是讓你知道 在海中解放絕對OK

  • and here's why:


  • First of, urine is mostly water.

    一 尿液主要成分是水

  • The average humans' urine is more than ninety five percent water.


  • And also the difference between 1 to 2 grams per liter of sodium and chloride ions,


  • guess what is in sea water?


  • The ocean is about ninety six point five percent H2O,

    海水中 水占了約96.5%

  • and has a higher concentration of sodium and chloride than urine.


  • Urine and sea water also contains a small amount of Potassium.

    同時 尿液和海水都含有微量的鉀

  • So far, so good!

    目前為止 一切都好!

  • Second, urine is the main waste product in the urea.

    第二 尿液中最主要的廢棄物是尿素

  • As the body's breakdown proteins and foods,


  • urines are the left over compound that get rid of excess nitrogen's of our bodies.


  • The man urea is just a part of expression,

    尿素 我不是說尿液 只是排泄的一小部分

  • a drop in the ocean.


  • The volume of Atlantic ocean is of, three hundred fifty quintillion liters.


  • That's three hundred fifty and eighteen zeros!


  • That every person on earth, in the average amount of pee,

    假設世上每個人 尿液量都符合標準

  • containing the average amount of urea, into the Atlantic,

    尿中含標準比例的尿素 所有人都尿在太平洋中

  • will be just sixty parts per trillion of urea in the ocean.


  • That's nothing guys

    各位 這根本就不算啥

  • plus urine contains a lot of nitrogen.

    另外 尿液中富含氮

  • Nitrogen combines of water to produce Ammonium,


  • which feeds ocean plant life.


  • So, no which we these guys, we're still good.

    所以 這其實不是在做壞事

  • Finally, forgetting all the fancy math.

    最後 不再提複雜的數學運算

  • Every animal in the ocean, pees in the ocean.

    其實 所有的海洋生物 都直接在海中尿尿

  • The fin whales was out about nine hundred and seventy liters of urine a-day.


  • That's more than two hundred and fifty liters!


  • So they are not harming things, you certainly as well.

    連長鬚鯨都對海洋無害了 你當然也是!

  • So, there you go. Don' be afraid to pee in the ocean.

    所以 結論來了 別怕在海中尿尿

  • And go back in worrying more important things,


  • like that shark ray behind you.


  • Oh, and we have to mention this:

    對了 得提提這點

  • Peeing in the ocean is totally fine.


  • But don't pee in protected areas, like reefs


  • or smaller bodies of water, especially swimming pools.

    在小水域解放也不妥 特別是游泳池

  • C&EN Reporter and Admitted Ocean Pee-Er.

    她是C&EN記者 也是海中尿尿合法會員

  • If you got a Chemistry question for us,


  • it doesn't matter how silly it is, I just talk about pee for two minutes,

    不管這問題有多笨 我剛剛才談尿尿談了兩分鐘

  • leave it in the comments and, find us on Facebook and Twitter.

  • Take a look in the science of ice cream or, how to get rid of your garlic breath.

    去看冰淇淋科學 或是擺脫嘴裡洋蔥味的方法

  • We'll back next week for more awesome chemistry!

So it is summer, and of course, of course you're heading up to the beach.
