At industrial (undiluted) strengths, there aren’t many chemicals that can’t damage tissue or potentially cause cancer. Constantly breathing the undiluted fumes or other exposures will certainly carry some risk in an Industrial application. Washing clothes in a dilute peroxide solution is not going to cause cancer, therefore simply walking outside to hang your clothes carries substantially more cancer risk than the use of Hydrogen Peroxide. Saying it causes cancer in “small amounts” is a bit like shouting at someone that stepping on a twig is destroying the entire forest…while standing next to an inferno. | | |

| ▲ | therealpygon 4 days ago | parent [-] | | I’m neither ingesting, inhaling, nor bathing in it, so I don’t care either, nor would I be concerned to wash my hands in it were it needed. Just drinking water or being outside is more than enough exposure to cancer to be worried about. |

| ▲ | kragen 5 days ago | parent [-] | | Well, it's part of the cancer process; most cancers couldn't survive without it. But that's also true of, for example, local production of DNA, or anaerobic glycolysis, or angioneogenesis. It's not true that if you expose tissues to lots of H₂O₂ they'll get cancer. |

| ▲ | thrgfu568 5 days ago | parent | prev | next [-] | | I'm also not a chemist... but I do have a PhD in mtls science from a top 10 program. My dissertation was on computational chemistry on organic compounds. You're 100% right. As long as the photon is energetic enough, it can cause a radical and therefore break a chemical bond. Brighter the sunlight, more peroxides (or radicals) made, more damage to your skin or your cloth's fibers. This is also why anti-oxidants are so effective at protecting the body, why inflammation is so damaging (body produces peroxides to eliminate what it believes is a threat), over consumption of food, too much/little exercise, etc. they all affect peroxide concentration or their halflife. | | |
| ▲ | metalman 4 days ago | parent | next [-] | | right, been glancing at this thread, and what occured to me is that blue light from LED's having a bleaching effect, specificly on yellow(cebum) organic compounds, then implys that it's not just(famously) hard on our eyes, it's frying them, and possibly worse.
I certainly mind a brite screen, and keep it at the minimum level, except when in sunlight or useing my phone to show family and customers things.
There are other effects to mass use of high powere LED's, where seagulls are flying around in downtown Halifax, NS in.the middle of the night, which I see now, but never happened with the old mercury vapour street lighting, which was it's own kind of wierd, in that it's bright yellow light from a distance, but makes everything under them monocromatic.IE: something in.the LED light wakes birds up. | |
