Hey there, welcome to Life Noggin! With summer approaching here in Blocko Land, I find myself constantly checking the thermometer to see how hot it is.
大家好！欢迎来到脑洞大开的生命奇想！在布鲁克岛，夏天的脚步越来越近，我经常拿起温度计看看这里有多热。
Once it hits 25 degrees celcius, you better believe you can find me hanging out at the beach, getting a tan, and playing volley block with my friends.
一旦温度到了25摄氏度时，我就会经常在海滩上，晒得皮肤黝黑，和朋友们玩着沙滩网球。
Now, even if this thermometer is filled with mercury, if it breaks, it won’t be that big of a deal.
现在，这个温度计里面充满了汞，即使它摔破了，也不会有什么事情。
But what about bigger quantities of mercury? What would inhaling, ingesting, or even absorbing those things do to you?
但是，如果是更大量的汞呢？如果我们不慎吸入、吞咽或者甚至是吸收了这些汞呢？
What!? These are just questions that i have! Don't look at me like that! High levels of mercury exposure can wreak havoc on your nervous system and your brain.
什么！？这就是我想提问的问题啊！不要用那种眼神看我好吗！大量的汞接触会严重破坏你的神经系统和大脑。
One thing that makes mercury especially dangerous is that it can cross the blood brain barrier and build up in the brain.
汞特别危险的一个原因是它能穿过血脑屏障，在大脑中积聚。
When mercury enters your system, it causes an increase in the amount of something called reactive oxygen species.
当汞进入你的身体时，它会导致体内活性氧数量的升高。
These molecules damage DNA and are strongly linked to the onset of conditions like cancer and neurodegenerative diseases like ALS, Parkinson's, and Alzheimer's.
这些分子可损害DNA，并且与癌症和肌萎缩侧索硬化症、帕金森症、阿兹海默症等神经退行性疾病的发生有密切的关系。
When it's consumed, mercury can start to accumulate in the heart as well as the brain.
汞摄入体内后，便开始在心脏和人脑中积聚。
It's believed that when mercury builds up in this area, it can cause cardiomyopathy, when the heart becomes enlarged and the tissue becomes thick and stiff.
当汞在心脏区域积聚的时候，它会导致心肌症的发生，届时心脏会增大，组织会变厚变硬。
This means that the heart can’t function properly and it slowly begins to decline.
这意味着心脏不能正常工作，并且它会慢慢开始衰弱。

Another key system that suffers when you ingest, inhale or otherwise consume mercury? Your kidneys.
当你吸入、吞咽或是以别的方式摄入汞的时候，另外一个会受累的重要器官就是你的肾脏。
These organs are vital in filtering blood and removing waste, but they're also a main target for mercury.
肾脏对于过滤人体血液和清除体内废物至关重要，但它们也是汞攻击的主要器官。
The presence of this toxin has been linked to renal cancer and chronic renal disease,
一直以来，汞就跟肾癌和慢性肾脏病的发生有关。
which leads to a gradual loss of kidney function, digestive problems, and what the Mayo Clinic calls "decreased mental sharpness".
慢性肾脏病会导致肾功能逐渐下降，消化系统问题，还有美国梅约诊所所说的“智力水平下降”。
None of this sounds good! Mercury poisoning has a whole slew of other effects like memory loss, skin rash, insomnia, and loss of peripheral vision.
这些问题听起来都不好！汞中毒还会带来很多其它的后果，比如失忆，皮疹，失眠，和周边视觉丧失等问题。
While small amounts of mercury are generally fine, heavy exposure causes all kinds of problems for the body and mind.
虽然少量的汞接触通常是没有问题的，但大量的汞接触会对身体和精神带来各种各样的问题。
Interestingly, how you consume mercury and the specific type of mercury actually plays a big part in how severe the effects will be.
有趣的是，摄入汞的方式和汞的类型对于带来后果的严重程度有很大的关系。
The three main types of mercury are Elemental, Organic and Inorganic. And they can be consumed in different ways- drank, eaten, inhaled, or absorbed through the skin.
汞的三种主要类型是单质、有机和无机。它们可以通过不同的方式摄入人体——饮用、食用、吸入或通过皮肤吸收。
The severity of mercury exposure varies widely among these combinations.
汞接触的方式和类型不同，损害的严重程度也会有很大区别。
For example, that silvery liquid form of mercury, Elemental Mercury, is so slippery that it'll just slide right through the stomach and intestines if it's swallowed.
例如，银色液体形式的汞就是元素汞，它非常滑，如果有人吞咽了它，它会直接从胃和肠里面流过去。
It seems like the inhalation of mercury vapors is what's most harmful.
看起来吸入汞蒸汽是最有害的。
And mercury vapors are surprisingly prevalent. People typically just think of thermometers and sushi when they think of mercury,
而且，令人惊讶的是汞蒸气非常常见。通常，人们说到汞的时候会想到温度计和寿司，
but the vaporized form of this element is also released by volcanic activity, mining operations, earthquakes, and the burning of fossil fuels.
但是像火山活动、采矿作业、地震、化石燃料燃烧都会释放出汞蒸气。
Poisons like mercury create a wide array of changes in the body depending on what the toxin is.
根据毒素的不同，像汞这样的毒素会在体内带来一系列不同的变化。
People can suffer from seizures, fall unconscious, or enter an altered mental state.
人们可能会遭受痉挛、昏倒或者精神异常等危害。
Of course, if you think you or someone else may have been poisoned by something, call 911 right away.
当然，如果你认为自己或他人可能中毒了，请马上拨打911。
Let us know in the comment section below what we should talk about next! we're taking suggestions for future videos!
请在评论区告诉我们下期你想讨论什么！我们会积极听取你们的建议！
Now that we know a bit more about mercury, I want you to check out this liquid.
现在既然我们对汞的了解又加深了一些，我想让你们想想这种液体。
Why does it move like that? What on earth is going on!? our friends at verge science explain why NASA made this magnetic liquid! Check it out!
为何它会这样移动？到底发生了什么事？我们在边缘科学栏目的朋友们会给你解释为什么美国国家航空和宇宙航行局会制造出这种磁性液体。去看看吧！
As always, my name is Blocko, this has been Life Noggin, don't forget to keep on thinking!
我是宝高，这里是脑洞大开的生命奇想。思考不要停！
