People on Lemmy should read links they post. As with any buffer system, the pH is balanced by the presence of both a weak acid (for example, H2CO3) and its conjugate base (for example, HCO−3) so that any excess acid or base introduced to the system is neutralized. A lot of academic labs love to get attention with alarmist claims, and assume the actual data was done properly. See DTT, see BPA, bullshit that never dies. permalink fedilink source parent hideshow 1 child comment replies: [–] fake_meows@sopuli.xyz 3 points 1 month ago* The literal paper that this post is about says multiple things about this subject. Did you read that paper? Thing #1 is that blood ph is decreasing in lockstep with atmospheric CO2. Thing #2 is that it appears the body's buffering system is stressed and is pulling additional calcium + phosphorus from the skeleton to aid in buffering. So your comment isn't wrong about the basic idea, you just didnt observe what's happening the larger context. PH is not only predicted to drop, we have already seen it drop, it's already started to happen. For this alarmist claim to be wrong, are you suggesting they cannot even accurately measure blood ph? permalink fedilink source parent
