Toxicity Definition and 19 Threads

I have been looking at pocket knives, seems like all the ones with G10 handle scales have a warning about cancer. This is a very typical pocket knife. https://www.chicagoknifeworks.com/steel-will-cutjack-c22m-linerlock-od/ You see the cancer warning message? The rest of the knife is all...

The article https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3888271/ claims (if I read it correctly) that there was an unusual increase in fetal deaths reported via the VAERS reporting system (which, it must be said, anybody can report, so the data there has to be taken with a grain of salt-- but...

Hello! I have recently become interested in purchasing some pastels, but I realized they contain a chemical called "Hexavalent chromium" or "chromium-6". I was wondering if this actually poses a threat to my well-being, considering there is a page about it here. P.S. This may not exactly belong...

I am woundering if there are any toxicologists on this forum so I could ask some questions (If they don't mind). For example, what data do you record on a day-to-day basis, how is it recorded and how it is made traceable. I have a rough idea, however I am not certain as I can't find anything on...

All the best science comes from TV shows, right? I just watched an ep of "Timeless", a new series about time traveling hijinks. In this ep, they want back to the Nevada bomb tests of 1962 and stole a plutonium core of what looked like the Fat Man atomic bomb. They brazenly took the ~4 inch...

Hi! I work in the movie business doing Special Effects. To create smoke for some effects we use "A+B Smoke." It is simply a mix of Acetic Acid (Part A) and Ammonium Hydroxide (Part B). However, the smoke effects is created when the VAPOURS of these 2 chemicals mix in the air. The MSDS Safety...

I recently received a 200g sample of pure (99.99%) bismuth for my little element collection. This thing is so cool! It was all broken in pieces and almost powdered, so i melted it into a beautiful ingot using my kitchen stove. Is this metal safe to touch and/or handle with bare, unprotected...

Is it safe to not use a glove to handle a small block of pure cobalt metal? Is a pure tungsten rod safe too? Are there any long term effects? Thank you so much.

First post here guys. Very quick background which brings me to the question i have. My trade background is in the automotive industry as a mechanic, mines as a drill fitter, hobbies include flying, cars and scuba diving. Just recently i have changed career paths again, and will be...

I am not a chemist but do have a concern regarding a coating that is applied to a linoleum flooring product likely soon to be used in my bedroom. Linoleum is the least toxic flooring type I could identify, suitable for the room in question. However, despite being made of 'natural' materials...

Hello, Would putting liquid paraffin (C_{n}H_{2n + 2}) in either a polyurethane or polyethylene bladder (such as a camelbak hydration bladder) create any compounds that have a higher toxicity than that of paraffin itself? I know that all petroleum distillates act as weak solvents and I'm...

I've done a bit of reading about manganese toxicity recently, and I was just wondering if anyone had anything to contribute about this topic. It seems evident from the research I've read that excess manganese (ingested or inhaled) is linked to problems in the nervous system similar to...

Here I found a scientific article in the International Journal of Biological Sciences concerning a study on rodents fed with genetically modified organisms. Two of the GMOs, MON 863 and NK603, are approved by the European Food Safety Authority. Here are the links...

First Post, Great Site. Appreciate your ideas! We always hear that plutonium is the most toxic material on earth. The reasoning as I understand it, is that plutonium oxide has many particles which are in the 0.1 micron or so range. Particles of this size are not removed from the lungs very...

I have a few questions about the synthesis and toxicity of hydrazine (N2H4). First of all, is it possible to synthesize hydrazine under a fume hood by mixing concentrated ammonia, sodium hypochlorite (bleach), and a gellatinous material (gelatin?)? I have read that high temperatures and high...

When I checked the wikipedia page for Indigo Carmine, the article there says : "Indigo carmine is harmful to the respiratory tract if swallowed. It is also an irritant to the skin and eyes.". But on a Streplis pack, menthol flavour it says: "Contains permitted colours: Indigo Carmine". If...

My teacher used a couple examples of real life water intoxication and his description of these evensts left me a little confused. One event he mentioned was a marathon on a cloudy, cold day where the runners were drinking despite the fact that they weren't sweating. My understanding was...

Steve Harris, M.D. The above doctor's quote suggests that Cyanoacrylate adhesives (Super Glue, Krazy Glue) may be used to cover cuts. He suggests that it is non-toxic, but I am skeptical. I heard of this before and wanted to recommend this to someone who cut their finger and plays a...

Hi, When considering all the various emotions that we as people demonstrate, Jealousy seems to me to be the most counter productive. As an energy it is self destructive and very corrupting. Jealousy is not just restricted to it's usual context but can be seen in so many ways...
