    Chemist (and biochemist) here. Organometallic compounds of Mercury are primarily dangerous because Mercury ions bond fairly strongly to soft ligands like sulfhydryl groups found near the active sites of enzymes. This can result in the displacement of the metal ions or otherwise disrupt the structure needed for enzyme functionality. Mercury metal OTOH is considerably less reactive. It is not safe to breathe in for prolonged periods of time but it is no where near as toxic as its organometallic derivatives are. Dimethyl Mercury for example, is extremely dangerous. A single drop has 100+ times the organomercury content needed to kill someone.




  • When I was in junior high there was a project that was worth half my grade that was announced on day 1 and due at the end of the semester. I waited until an hour before it was due to start working on it. I got an A. I can only imagine what I could have done if I had worked on it consistently throughout the semester like a normal person.

    The whole point of ADHD being diagnosed is that it has become a problem. Enough of one that people wait months if not years on a list to be assessed and pay hundreds, thousands of dollars for that assessment depending on insurance or lack thereof. And because of the pandemic shortages, a lot of people have trouble obtaining medication or in my case, they had bad reactions to specific types and need to find ones that work without those side effects. I was fortunate. My therapist was neurodivergent and made sure that I got support even before I was formally diagnosed.
