If you are concerned about rising levels of mercury in the air, especially if you live in an area where its a serious problem for any one of many reasons, (Use of certain kinds of coal, or tilling of land may be two) you should invest in a bunch of NAC, and take it daily, whenever you remember to. Not only will this improve health generally by raising glutathione, but it will also allow your body to rapidly remove Hg from your body via the glutathione route. It will also make you more resistant to a great many diseases. Your body needs glutathione more and more as you age and NAC is the best way I know of to ensure you get enough of it. You cant ingest it orally, its made from cysteine, glutamine and glycine in your diet, cysteine being the rate limiting one. https://pubmed.ncbi.nlm.nih.gov/?term=n-acetyl-cysteine https://pubmed.ncbi.nlm.nih.gov/?term=glutathione ...since youre concerned about elemental Hg in the atmosphere, you're clearly concerned about glutathione as thats (depleting glutathione in our bodies) elemental Hg's main adverse effect, from what I know. You can read more at nutrition.org for free. As we get older we need more and more cysteine in our diets. (whey and dairy products being the most abundanbt dietary source besides n-acetyl-cysteine. I usually buy a kilo of it at a time and ensapsulate it in big OOO caps because its handy to have around. One effect of doing this is hearing loss prevention. Lots of little things like that. |

I Highly recommend you only ever buy LED lights that you can control their output power on. Then run them at lower than rated power. Either using a dimmer, variable power supply or whatever. Set them up so they run under 60degC. If you can't touch them with your finger then they are running too hot. A lot of the LED lights you by run at 85degC. They are engineered to fail. This is why I love LED strip. It spreads the heat dissipation from ~100 leds over many meters of strip instead of in one big ball. And if the psu fails you can replace the psu without replacing the leds themselves. |

Remove the PCB strip, stick a 12V LED strip on the aluminium and you'll have a nice workbench light which will last for a long time. |

By what mechanism does the NAC sense the concerns and help with them? For your concerns, I'd recommend homeopathic products. They are less likely to do any harm than actual nutritional supplements (or medication). |
