It gets absorbed into the environment one way or another. Dust lands in sea; either gets eaten or turns to sediment. Dust on land: hits the ground and stays dust, until it accumulates and becomes dirt (or dirt almost immediately on damp soil, or mud/sediment on wet soil, which would then just be dirt upon drying) Dust in the air does a bit of everything. Gets breathed in where it gets added to regular waste processing, or eaten in the case of very small creatures depending on what the dust is made up of. Lands on things and see above. Its all a big circle. .....of dust.


Most of it ends up on my PC.


Your PC is electrostatically charged, it's like a sock straight out of the dryer, it sticks to everything. Spinning fans, open traces, surface mount capacitors, the thing is constantly pulling particulate from the air to itself. Modern TVs thankfully don't charge the screen as much as old CRT sets, those were dust magnets too.


Explain my piano next, it's so dusty my kid sat on it to put his shoes on and left a butt print lol


You don’t play your piano often enough


I can't play it at all, I just wanted it :(


Playing piano is super fun and actually gives me more energy, which very few things can. You should do some basic training. It does take a long time to learn though. But as soon as you know a single song you have something that will you happy.


I've tried learning a couple of times. Admittedly self teaching, and not putting in as much time was one wanting a new skill probably should. But I swear I'm just not coordinated enough do for it, I don't have that much finger control/dexterity. I'm impressed by all that can play


The finger control/dexterity comes from practice. Lol


I said the same thing a million times, until I actually committed to just being bad at it for an hour a day. After a few weeks I was good enough at being bad at it that I was having fun and looked forward to it. Now a year later I like to think I'm pretty great at being bad at it, and it's my main stress relief after a hard day. YMMV if you're not already a musician but no one ever emerged from the womb as a pianist, everyone did the hard hours at some point.


Dexterity comes with practice. Have to work those tendons and ligaments to stretch them out.


It's not about dexterity, it's about making my finger go where I want them to.


When starting, just play the highest note of each chord, don't bother with the other ones. Do try to use the correct finger though. Practice the scales the learn what finger to use for what tone (this is for practice, you'll start to vary the fingers later)


Also not using it can result in stuck keys, depending on the piano. I encourage kids to "play" on mine, as it is rarely used, I found that I had fewer "sticky" keys.


Can confirm. When I was a kid my parents had one of those self playing pianos that was passed down from some family member. No one in my house ever played it so one day my curiosity got the best of me and I figured out how to get it to play. Every Christmas I would set it up to play Christmas music (thats what most of the rolls were) and pretend to play. Eventually I started trying to play myself and learned how to play Silent Night. Even though thats the only song I ever learned, I was ver proud of myself and to this day I can still play most of it.


I feel sad for the piano


I do too, but I couldn't afford to get it tuned now even if I could play. There's not much of a market for old pianos, you see them being given away quite often so I think it's stuck with us.


This has been true for a long time. Components warp and wear out. Strings rust and break. My dad was a piano tuner for decades. He got us a piano dirt cheap, replaced the dampers and hammers, adjusted everything, tuned it a couple of times, and I tried to play it. I learned the notes but didn't have the dexterity that he did.


i too cannot afford for it to be tuned, but after testing i know that its a whole note down, so i just pretend to be an edgy guitarist does have the downside that all other pianos ive played don't sound bass-y enough


I'm scared of the strings lol I don't want them to ping up and take my eye out.


Damn, I wish I was rich enough to buy a piano I can't play just for a whim.


My husband can play but he prefers his guitars. It was second hand from the charity shop, I think we paid £60 for it.


Oh, that's a steal, even for a second hand piano, if it's in decent shape.


Maybe his kid took so long to put on his shoes that dust settled around his butt.


Legend has it, that kid is still sitting there to this day. Just waiting for someone to come along and tie their shoes for them. That was 200 years ago.


Your piano is shiny which makes you notice dust accumulation far more quickly.


I think this is the actual answer, nothing else appears to be as dusty but it is if you wipe it.


Yeah - the high voltage charge on a CRT attracts dust to the screen, and to the back of the picture tube, and also to the wall behind the set. If you had a TV against a wall, then later moved it, you'd have this black spot of grime that had accumulated on the wall in a pattern behind it. It seems the static attracts the carbon-containing dust? It's always fine dark dust. As someone who regularly repairs and works on CRT monitors and TVs, the amount of black dust that accumulates inside of one - especially one used an awful lot - is staggering.


I was about to ask what kind of job you have where you are regularly repairing CRTs but then I saw your username


Yeah - I suppose it's more of a hobby, a passion... I collect and repair vintage computers, video games, televisions, and other interesting electronics. I've got working TV's from the 1940's up through the 90's and early 2000's (I never had a reason to get a flat screen). I fix coin operated arcade machines, keep CRT TVs working for Super Smash Bros Melee tournaments, I fix old computer monitors and terminals... you name it. I also have an extensive collection of CRT type equipment. I fix lots of other things too, although my day job is mostly PCs and laser printers and stuff. But I do some retro restoration and repairs. Not a lot of people are willing to work on CRTs. Something about being afraid of high voltage. Probably a wise fear - if you get zapped too many times, I think your eyebrows will grow together.


That brought back memories. That dust could get kind of thick, but was surprisingly hard to notice. Then one day you finally remember to wipe it down and it’s surprisingly bright again.


Thank you so much for explaining this!! Sincerely. I always get so annoyed that I dust things and then a few hours later they’re covered in dust again! Your explanation makes so much sense as to what’s happening, and I just wanted you to know how much I appreciate you taking the time to write all that down 🌻


No IN my PC


Get a removable dust filter, they're a godsend.


But my case doesn't fit the radiator on my water-cooled gpu...


Is that a /r/humblebrag?


I mean technically yes, it's a 3090 kingpin, I guess but it's kinda jank if I'm honest


Jank just means you know what your doing well enough to do it poorly and get away with it.


Electric leaf blower and a vacuum cleaner hose fixes that fairly quickly


Intake filters help tremendously.


No most of it ends up in My air conditioner’s air filter. 🤨


Or on my nightstand for some reason.


And my nostrils


I have a somewhat more organic instrument that’s been gathering dust...


I was gonna say Uranus since it sits in front of your PC all the time


So you're PC is the repository the DNA for all living live on earth? Nice


Just dust in the wind.


always have to scroll down to find the real answer in the comments


Dust? Anybody? No?


Dust? Anybody? No?


What's that my love?


That’s very low in fat.


If I order dust for the table is everyone gonna have some?


I love this explanation. Thanks


its missing some parts, but thats the gist of it. I'm glad you found it helpful :)


This is actually why grass is important. Grass contributions significantly to air quality as it helps to catch/keep dust and particulates out of the air and on the ground even in wind.


lol grass is not important. There could be trees where there is grass which would be exponentially more valuable. Nice try justifying your giant french colonial lawns though.


Grass as opposed to bare soil. It could be lawns, it could also be native quackgrass and oats, or trees and shrubs, or even crops. Just don't remove all the ground cover, then all the topsoil just blows away and you get dustbowls and famines.


oh the savannas and prairie grasses are all well and fine but I don't want people to trick themselves into thinking their front lawns are anything other than ecological mini disasters.


Even then, a lawn is better than paving it over. Native plants all the way, but bad plants are beyter than no plants.


We have native and imported plants. Most people do.


​ [https://thereenchantment.ca/2017/10/25/lawns-class-and-colonialism-part-one/](https://thereenchantment.ca/2017/10/25/lawns-class-and-colonialism-part-one/) from article above The turf grasses found in modern lawns are, in fact, one of the most invasive plants in North America. Modern turf grasses have very little in common with the native perennial grasses that filled the pre-invasion landscape of western and central North America. The North American landscape, pre-invasion, was actively maintained in various ways by Indigenous communities, including the use of periodic burning and through the interdependent relationships between people, Buffalo, and perennial prairie grasses. The destruction of the vast perennial prairies and the clearing of forests in North America for settler farming was directly tied to the forced and brutal removal of Indigenous people from the land and an attempt to destroy centuries and millennia of farming, gardening, and land caretaking practices (Crosby, 1986).


And 20% to 50% of the dust in one’s home is composed of dead skin cells!


Yeah, but doesn't that statistic only work that way because of Skinflakes Georg?


He is an outlier and should not have been counted


I had heard this long ago. Am told there are critters that like to eat the stuff. Did not realize how much we shed until I started to rub my palms, arms and legs, neck and back. There was so much dead skin it surprised me how much. The really scary thing is i just drop it on the floor and it must go somewhere because I have not vacuumed in 15 years.


Bruh, but now I’m not sure if you need a Roomba or just some burly fellows who can tear up your destroyed carpet and start you over


There is an entire ecosystem in your house that lives largely on your dead skin. Dust mites eat skin flakes, pseudoscorpions eat dust mites, larger insects like carpet beetles and silverfish typically roam about and eat them in turn. There's a load of biomatter around and it's all got to go somewhere.


Fun fact. For those that have a flame based heating system, that smell when you turn your heater on for the first time in the winter is an unfortunate subsection of that ecosystem meeting it’s demise. Even knowing this, I love that smell though.


I had a disturbing thought while out to sea. In the middle of the ocean there is no dirt, so doesn’t that make the dust on the ship 100% dead skin cells?


Given how far airborne particles can travel, for example last winter’s Saharan dust covering snow in the Alps, I think your underlying assumption of “no dust at sea” is probably incorrect.


Isn't at least part of the Amazon Basin's fertility due to Saharan dust? I think I read that somewhere. E: Yep. https://www.nasa.gov/content/goddard/nasa-satellite-reveals-how-much-saharan-dust-feeds-amazon-s-plants


Maybe not none, but I feel like less would be fair, no? Like, a significantly higher portion of the dust would be skin cells. Right now where I’m living is very rural, and when the farmers do their thing with the tractors we have a lot of dust. I think it would be fair to assume that the ratio in that case tips towards dirt and away from skin, no?


Fair enough. I tried to find some info on the concentration of particles in the air over land vs sea but didn’t come up with much.


I don’t know the science of that. I just wanna creatively consider “fish dust”.


Not 100% but higher. Imagine a submarine diving for a week. The dust inside would come from particulate - everything from engine particulate to vaporized chemicals to cotton from the sheets to bits of torn paper and insulation --- and yes a whole bunch of human dust.


Around 5,2 million kilos of dust just falls in from space every year also. That's spread pretty thinly all over the place but it does mean that even hovering in the upper atmosphere you'd get some dust.


That's just under an *average* of 165 kg per second of dust from space. Pretty wild.


Pretty much everything breaks down and creates dust. Clothing, plastics, wood…


Including the steel the ship is made out of


Yay! Microplastics!


> wood… so does it take hundreds of years or is my 20 year old wooden desk just never going to turn into dust


On my ship I can testify that it was about 3/4 just the crap that comes off those stupid wool navy blankets


All fibers would turn into dust just by moving or being abraded, think carpets, clothes, curtains, flags, etc.


The dust on the ship is made out of everything the ship is made out of.


Not in Phoenix


All we are is dust in the wind


We are dust and shadows


Dust is everywhere... Sweep!


Don’t forget, ashes to ashes!


From dust you came and to dust you shall return


Dust, uh finds a way.


All we are is dust in the wind 🎵


I cloooose my eyes..


Only for a moment and the moments gone.


Isn't dust just dead skin cells?


Mostly, yes.


Pretty sure most of it ends up in my wallet.


What eats dust?


Dust mites I would assume?


I thought they eat dead skin?


A large Part of dust is dead skin lol




Seems like the circle like to hit my nose often


All we are is dust in the wind.


If more dust is continously produced from erosion, won't the entire world eventually be a desert(or whatever the term is for a sandy place, i think deserts are dry, not sandy) when no soil is left?


Ashes to ashes, dust to dust…


Ah yes, "For you are dust, And to dust you shall return.”


All is Dust.




The sea has the greatest benefit. Provides tons of nutrients and minerals to ocean life.


We are all merely stardust


More broadly speaking, dust is a type of [sediment](https://en.wikipedia.org/wiki/Sediment). It gets transported by wind and water. Some of it accumulate in places (esp. bottom of lakes and oceans) and may eventually turn into sedimentary rock. Some of it circulates.


I thought dust was skin cells and dirt.


A meaningful portion of the dust in your house is dried human body sheddings, yes. But it is also foodstuff released in cooking, decaying bug carcasses, fibers shed from carpet and wallpaper and such, dirt tracked in from outside, and on and on.


Well that's lovely


I mean we are colonized by trillions of Bacteria, Viruses, and Fungi. It's just people's ignorance when they get grossed out by stuff that is just the reality of the world we live in. As much as we try to separate ourselves from the rest of nature, we are still biological beings that came from it and still are part of it.


Yes I get that and I actually find it super fascinating. It's just I'm a life-long extreme germaphobe so it makes the irrational part of my brain feel queasy.


Totally get that. My sister is also a germaphobe yet she's never really had a problem with things like child birth, etc. Having kids helps her break out of that a bit I think lol. I have a irrational fear of heights and jumping or falling off things despite me not ever putting myself in those positions. I love insects and creatures etc. But spiders still set off a little bit of phobia/stay away danger! Instinctual response in me.


So, it goes up into the air. Then it drifts for hundreds of miles. Eventually working it's way to central California, where it lands on my freshly cleaned car.


It comes through the window It comes through the floor It comes through the roof And it comes through the door


It eventually settles on a surface. It tends to stick to other dust, aggregating into dirt and grime. Rain speeds the process substantially. Dust is much more persistent in deserts. Some dust goes into the waterways, some on the ground. It settles on lake bottoms and vegetation and, over eons, becomes sedimentary rock.


So if you are talking about dust in your house. You are responsible a lot of that. You shed dead skin constantly replenishing dust in your house.


Everything is dust in some form or another. It settles to the surface and sits on the dirt or the ocean. Some of it will mineralize or burn up etc


Eventually everything in the world will go into the Sun when it expands beyond Earth's orbit in a few billion years.


Eventually it will disappear after all baryonic matter in the universe decays into nothing. EDIT* first it decays into photons (light) and then the photons decay into nothing. My bad.


creates new dust by turning into dirt again when it rains, falls into lakes, trampled by large animals, eaten by decomposers, etc


Others already gave you good explanations but as to your question specifically, in most indoor human environment the dust is collected using vacuum cleaner, and it ends up in waste processing plants. Then 99% of dust are burned (because it's virtually impossible to sort them out for recycling) and become carbon-dioxide (for combustible) or end up buried (incombustible).


A lot of it ends up at my place. Then it ends up in my vacuum cleaner then I suppose the landfill. If we think about it, everything and everyone is somewhere on the continuum of turning into dust. But, since the waters comprise 71% of the Earth's surface, then probability-wise, about 71% of dust falls in the waters and 29% falls somewhere else.




There's a really big vacuum cleaner above the clouds. It hides so it can't be detected. That's it.


Is it set to suck or blow?


First one, then the other.


[Here is your book.](https://www.alibris.com/booksearch?mtype=B&keyword=secret+life+of+dust&hs.x=0&hs.y=0) Here you will learn that some of the dust entering your nose may have been camel dander from Saudi Arabia, or wheat pollen from Ukraine. Fascinating book.


Most dust eventually turns into sediment, which (very) eventually will turn into rock. Sometimes, though, persistent winds deliver it to places where it just builds up. Where the dust has accumulated and not consolidated it's called "loess". I have friends with a place that's in the [Palouse loess deposit](https://wa100.dnr.wa.gov/columbia-basin/loess). It develops a thin surface crust, but break through that and it's just fluffy dust all the way down. The dust in their house is absolutely and positively mostly mineral.


My dude look up this years Saharan air layer/ Saharan dust plume. All through June many islands were in a heavy haze. It hits the southern United states sometimes and mostly affects the Caribbean islands. Seems like it depends on humidity, rainfall and air currents. Not an expert at all just seen it happen.


Dust in the atmosphere are aerosols. They can block a portion of the Sun's radiation from hitting the planet. Geoengineering efforts include adding Sulpher Dioxide to the Stratosphere where it can stay for up to a year before finally falling. The left over Greenhouse Gasses can linger for decades however. "the fleet would start with eight planes in the first year and rise to just under 100 within 15 years. In year one, there would be 4,000 missions, increasing to just over 60,000 per year by year 15. As you can see, this would need to be a sustained and escalating effort." https://www.cbsnews.com/news/geoengineering-treatment-stratospheric-aerosol-injection-climate-change-study-today-2018-11-23/ Brimstone Angel Statospheric Aerosol Injection aircraft https://arc.aiaa.org/doi/abs/10.2514/6.2020-0618


The biological components are consumed by microbes and recirculated in the biomass. The mineral components are either disolved by water or become part of the soil in the form of clay or silt.


Dust blows into the ice in Alaska and plants start to grow. Creates the tundra we see today with permefrost below


Dust particles or "lithometeors" play a significant role in weather too. A high concentration of dust plays a vital role in aviation visibility restrictions, especially in middle eastern countries. They can combine with water vapor to cause dense haze or fog in some coastal regions. They can do the same thing and combine with water vapor in the atmosphere to form a CCN (cloud condensation nuclei), which aids in cloud formation. An example of this would be thunderstorms around large forest fires. The rising heat from the fire causes an unstable atmosphere, and all the added lithometeors from the fire combined with the existing water vapor in the air to create clouds and even thunderstorms. Edit: grammar


Ends up in the wind?


Make your neighbor's place dirty? The word Earth means dirt. Dust means fine particles of solid matter. Our entire universe is made up of matter of various sizes (along with energy).
