    @dantheclamman @JDGeoShack dunno, I feel with age comes anger and rage against capitalism and conservative politicians (i.e. all that aren’t on the very left end of the spectrum these days, which is basically the 90s center left). But maybe that’s not about age, more about a system hellbent on ending humanity? 🤔

              I know I'm a broken record (or looping GIF) on this, but a large reason Pb levels aren't even lower is Avgas, the 100-octane gasoline fuel burned in virtually all reciprocating-engine aircraft, which still contains tetraethyl lead.

                  @martinvermeer @dantheclamman Truthfully, this would be very hard data to draw any conclusions from. There are just too many other factors. For instance, the shift from mostly human manufacturing to mostly robotic manufacturing (which began happening at increasing scale post WWII) the stagnation of wages are going to drive crime. Also the CIA selling arms to Iran to buy drugs from Noriega to dump on US streets to increase crime as a way to attack minorities. Too many factors. Hard to isolate.

                          Lead was also found in pipes, gasoline, paints, etc. And amalgam is still used today. When it comes out, it is hazardous waste.

                              The damage done by this is staggering. It will continue to effect humans for several generations. Leaded paint will also be an issue for decades to come.

                                @obscurestar @martinvermeer @dantheclamman Actually, the lead-crime correlation shows up across all industrialized societies in 20c. That the curves line up despite different countries industrializing and moving to automobiles at different times indicates that lead exposure was a major factor. It was not contained in the US, far from it.

                                I think the burden of proof is on those who suggest that what we know to be true about lead exposure for individuals and small groups of people somehow doesn't scale to large groups.

                                  @tasket @martinvermeer @dantheclamman I don't at all doubt that lead, particularly tetraethyl lead isn't toxic and a contaminant on a massive scale (not to mention used for the stupidest pure greed reasons). Even the Romans knew that lead was bad news. Correlation across many industrialized nations can well constitute a smoking gun but correlation is not always causation. Just urging caution with blanket statements.

                                    @obscurestar @tasket @martinvermeer Yes, caution is merited. A recent meta-analysis showed there probably is an association between lead exposure and crime, but the relationship is not cut-and-dry. It explains some of the variance, but there are other contingent factors or "confounders" at play, with kids exposed to high lead and also having greater socioeconomic need showing the biggest negative effect. The review authors point out many studies do not account for that and some other interactive effects. https://pmc.ncbi.nlm.nih.gov/articles/PMC10393136/#sec011

                                      @ThePolishDispatch @dantheclamman People aren't talking about it, but the people in charge of businesses and governments around the world are exactly the age group who received the maximum doses of environmental lead. I strongly suspect that this fact is behind our worldwide political instability. I'm in this age range and I think that we need to take away grandpa's car keys.

                                        A big shoutout to BP's Kwinana refinery which, with the complicity of WA's corporate captured government kept producing leaded petrol way past 1996.

                                        The government's own article below celebrates this remarkable achievement.
