Italics mine: >The study, described as "a wake-up call", also estimated that exposure to the toxic metal causes young children in developing countries to lose an average of nearly six IQ points each. >Their model estimates that 5.5 million adults died from heart disease in 2019 because of lead exposure, 90 percent of them in low- and middle-income countries. >The research also estimated that children under five lost a cumulative 765 million IQ points due to lead poisoning globally in 2019, with 95 percent of those losses coming in developing countries. In the article, the 1 IQ point loss level is shown at about 0.25 ug/dL. I don't think this is likely in the US from brass pipe fittings containing 0.5% lead or whatever. I'm not saying that tight lead regulations are/would be bad, but this study seems to focus on the far higher disease and death burden of lead in less developed countries. Dealing with lead exposure in developing countries would likely have large returns for the global economy, and since plenty of lead pipes were probably laid by colonial powers, has the ring of a moral imperative. But how?
