Toxicity

Does anyone know how toxic the foam inside a refrigerator door is (Urethan foam?)? Is there any danger in coming into contact with it? All I can seem to find online is long-term effect of the foam on the environment (which are apparently very bad). In short, should I cover up the back of the door and never think about again, or can I remove it from the door with a chisel without much worry? I want to remove the foam because it looks a little moldy on the top. Any suggestions? I'm making a magnetic bulletin board for my wall in case you were wondering. thanks, Randy

Toxic Magnet Wire?

I know I'm probably going to sound like an idiot for asking, but can magnet wire release any toxic fumes when heated? I made a speaker using a magnet-wire coil and a neo-magnet, and when I plug it into the amp, I realized the coil gets very hot. I was expecting this, for I've used a number of coils in other projects. There is an odor, no doubt, that comes from every coil I've used when making an electromagnet. Sure, the smell may come from the iron nail being heated, but I always associate the smell with the coil. I'm not willing to smell this speaker, however. So, is there any risks that come from the heating of magnet wire? The coil gets hot after about a minute of run-time, but I'd like to be able to run through an entire album of music (an hour?) if possible. Thanks!

Toxic glue in dishwasher

My spouse washed a bunch of antique children’s china in the dishwasher. They were from a garage sale and he didn’t realize some had been glued back together. The glue must have broken down and melted during the wash. Now the dishwasher smells awful (like chemicals) along with everything that was washed in it. Do we need to replace it?

Green isn't all that green after all

While the color green has been the hue of choice for environmentalists and companies wishing to show that they care about nature, making a product green is actually toxic. Due to the difficulty of making a green dye and all the chemicals that are used, it contaminates anything it touches. So when a product is simply putting some green to make it look a little more nature-friendly, it's actually making things worse. Yay! From the NY Times: Take Pigment Green 7, the commonest shade of green used in plastics and paper. It is an organic pigment but contains chlorine, some forms of which can cause cancer and birth defects. Another popular shade, Pigment Green 36, includes potentially hazardous bromide atoms as well as chlorine; while inorganic Pigment Green 50 is a noxious cocktail of cobalt, titanium, nickel and zinc oxide. The Toxic Side of Being, Literally, Green

Why participate in Pepsi greenwash?

I don't know about the rest of Instructables community, but I am extremely reluctant to contribute anything to Pepsi's latest (https://www.instructables.com/contest/pepsirefreshproject/)  greenwash campaign, well, anything except criticism. PepsiCo (PEP) is a company that produces semi-addictive, food-like consumables that, in the aggregate, are actually harming people's health. They're also littering the world with PET plastic bottles. Previous Instructables alliances with companies that make tools or building supplies (Black and Decker, Leatherman, Gorilla Glue), these alliances made sense to me since these companies actually make products to help people to build things. PepsiCo is essentially a manufacturer of recreational over-the-counter drugs, similar to beer, liquor, cigarettes.  Thus alliances with entertainment industry (e.g. ball games, car racing, crappy pop musicians) would make sense to me, but not an alliance with Instructables.com, whom I like to think is doing something more noble than just crass, brain-numbing entertainment. If you'd like to see PepsiCo's official explanation of this "Refresh the World" business, but without being tracked by DoubleClick, the direct link is: http://www.refresheverything.com/how-it-works Pepsi says they want to change the world, but I think they just want to sell more soft drinks.  I don't see them as a serious agent for change in the world.  IMHO, the revolution will NOT go better with Pepsi! Update:  Many of people responding to this topic seem to think that I'm lobbying for the prohibition of soft drinks, but this is not my goal. In truth I wish more recreational drugs would be allowed to have the same legal "white market" status that sweetened drinks and snack foods enjoy. The point I was trying to make is that Pepsi is an inappropriate choice for an Instructables alliance because the basic values of the two companies are so different. Pepsi does not embody the DIY (do it yourself) philosophy. Rather the values of PepsiCo are convenience and instant gratification. This is essentially a SEDIFY philosophy (somebody else do it for you), the polar opposite of DIY. The reason I mentioned harm to the heath of people and the planet, is just to demonstrate that Pepsi does have cause to want to improve, or greenwash, their image, which is I suspect the point of their "refresh project", not just pure philanthropy.

Is lighter flame/smoke/fume toxic?

I was going to make an instructable on mini roasting when something hit me. When you use the lighter to light maybe a marshmellow, is the fire or smoke or fumes from the fire toxic? I mean the gas/alcohol gets neutrilized when it burns up and turns into flame but If i cook with it, it may be a different question. If someone asks me to think about smokes, the I should say to you that smokes are already toxic and anyone smoking shouldn't care. ( I don't smoke, I want to live) If possible you can answer this question and have credit in my next instructable.

What is a chronically toxic dose of eugenol?

How much cloves is too much? I see on the MSDS that the rat LD50 is 1930 mg/kg, which no reasonable person would consume in one day. But I wonder about the effects of consuming a large amount every day. Can anyone find some data on the lowest reported oral dose of eugenol (in mg per kg) that showed long-term toxicity in a human? Or, conversely, the highest reported dose that was shown to be nontoxic over the long-term?

"What's that awful smell?"

Right at the end of our daily meeting this foul stench began to swirl around us. We couldn't quite figure out what or where it was coming from, but it was nasty. At first we checked the laser cutter since some people in the building like to occasionally burn Stuff That Shouldn't Be Burned and oh man does it reek. But that wasn't it. We check the fridge, but it was fine. We even discovered that it was just inside the building, but we had no luck figuring it out. Then Mike from Potenco walked down the hall and said, "Oh, hey, sorry about the smell. I blew up the transformer." He grinned and walked off to find all the fans in the building to air the place out. Just another day at the tower and another experiment gone awry. But if you don't blow anything up, then you're not going to make any real progress, right?

Is Olive Wood Dangerous for Woodworking? TOXIC?

I've been wanting to make a small mallet out of a tree branch, And I recently spotted a small olive tree branch that fell. Since I'm pretty new to woodworking, I thought I'd google the wood to find out it's properties, This is the confusing thing that I found: Here, It says that Olive Wood is commonly used for "kitchen utensils, carved wooden bowls, cutting boards, fine furniture, and decorative items", Which means that it should barely be something allergenic, Aka safe to use, Since it's used with food. But here, It says that Olive Wood is "Olive trees are extremely allergenic, with an OPALS allergy scale rating of 10 out of 10" aka "9-10 Extremely high potential to cause allergies, should be replaced with less allergenic species". Now I'm confused... Does anyone know what really is true?

Is a CRT electron gun any use?

Is it worth it to take the electron gun out of a CRT when salvaging parts? I've seen people remove the electron gun when they take apart the CRT but I don't know what they'd use it for. What can you do with a CRT electron gun? What chemicals does the gun contain? (I know the screen has toxic phosphor and stuff but I'm talking about the gun itself). Also, is it safe to vent a CRT tube? I have found that you should vent the CRT tube before working on it, by smashing the end from a distance, so that it won't implode if you happen to break it when working on it. But is it safe to puncture open the tube? There are toxic phosphors inside and I worry that venting it could cause toxic chemicals to go airborne.

Chinchilla-safe material for food-bowl

My chinchilla is, for the most part, a jerk. She is adorable, though, so I'll keep her. I can keep up with all of the ways she tries to antagonize me (I've come to the realization that she really is out to get me :P ), except for one. She often pushes her food bowl off of the ledge. I would move it to a lower area in her cage, but, as I came to realize the first time, she poops into the bowl when it's below her. So, I must keep it on this ledge. I therefore need a way to attach and un-attach the bowl to the cage (so I can fill it with food afterwords). I could just go and buy one of these food-bowls,  but I'm too cheap and like to make my own stuff, anyways. So I have two questions - what material would be best for attaching it to the cage, and would hot glue work as an adhesive? I am worried about her gnawing on the stuff, because I know certain things can kill her if she eats them (eg: Paint). Thanks! :)

My freind has a large supply of microscopic gold particles, however they need to be separated from sulphides. there is a high concentration of gold in this solution, and millions of dollars could be made. however, heating the sulphides will make sulpheric acid, which burns away your lungs (also used in chemical warfare). chemicals currently used for the process of separating sulphides from gold are very toxic, and also expensive. the chemical process is very inefficient too. i am looking for a way to separate sulphides from gold without using (toxic, dangerous, expensive, rare) chemicals.

Non-toxic, natural, cheap and WATER-PROOF adhesive or glue, is this impossible?

I'm a quality engineer working for a company in Turkey, the company collects the coaldust ( powder form of the coal )  from all the cities of Turkey and makes them briquettes by pressing with very powerful machines. Of course we use some adhesives for mechanical strength of the briquettes. We use CMC (a kind of cellulose) and this material is soluable in water. So our briquettes are not very durable under rain or moisture. Now I have to change the binder or adhesive materials in order to produce waterproof briquettes. I dont know how it's possible. I have to use nontoxic natural materials, and cheap as well. Last week I tried to do something but we were unlucky maybe. I tried to use Technical Gelatin and Alum (Al. Sulphate ) together, the briquettes seemed very good after production but they were not durable when I left them in a cup of water. So I have to find a solution now. Can you help me about that? I'd be very pleased. Thanks.

Question by Toxicity   |  last reply


This is how you can preserve food.

Echoing what the others say, it's all about "available water".Salt and sugar does the same thing - draw water away, or make the water too salty/sugary for bacteria to live in it.Things that change the acidity kind of does the same thing - they make the water inhospitable, so the bacteria can't live in it.You can also make a mix of the two, using a bit of vinegar and a bit of sugar.Drying something also takes away the water.This is what is done with jellies and jam and fruit preserve and a lot of other things - olives too.The only thing that's different from all of these only works on things that are sterile - you can cover the outside in something that's toxic.The toxic thing can be a mold, strangely enough - because the mold makes toxins to protect itself, so other bacteria and molds can't survive. But it means you have to cut the outside away when you want to use it, and then you can't leave it, because you've opened a door for bacteria and different molds to "enter".Camembert is like this - the outer layer is a living mold that kills everything else.The toxic thing can also be residue from smoke because the thin outer layer is toxic, the bacteria can't enter. We can take a big bite of it, though, because the layer is very thin, so there's not enough toxin to affect us.bacon and fish are often preserved like this
