The first link in the article contains PPM, and if you click through it lists % actionable levels for the individual brands / contaminants: https://tamararubin.com/2025/01/toothpaste-chart/ https://tamararubin.com/2025/01/toothpaste-chart/ Maybe HN should just link to this? Incidentally, apparently, they test based on donations from their reader base. Most of their readers are interested in weird fluoride-free stuff. If you want them to test more mainstream brands, you can send them money: https://tamararubin.com/2025/02/lead-safe-mama-llc-fundraisers-for-toothpaste-testing/ https://tamararubin.com/2025/02/lead-safe-mama-llc-fundraise... I'm not endorsing them, and have no idea how well they conduct their tests, etc. There might be a better way to fund independent testing of consumer products.
