Lead bioaccumulates, it stays in your body until you die, there's no mechanism to remove lead. The scientific consensus is that there is no safe level of lead exposure. See https://pubmed.ncbi.nlm.nih.gov/27837574/ or even the CDC: "No safe blood lead level in children has been identified. Even low levels of lead in blood have been shown to affect learning, ability to pay attention, and academic achievement. " https://www.cdc.gov/nceh/lead/prevention/default.htm
So, yes, there are a lot of toxic things in the environment and I'm not concerned about most of them but lead is dangerous and has been proven to be. There is also no reason whatsoever for a company to use lead paint (which has been banned for constructions in the 70s) on a product meant to be used for children (a baby bottle).
The FDA didn't care about lead when it was being spooned directly to infant's mouths in the form of their baby food. The standards aren't what they are because of the amount of risk to people's health, or they would never have allowed it. I wouldn't assume something was safe just because it met FDA standards/recommendations.
The report found that the FDA's inaction and approach "appears designed to be protective of baby food manufacturers." if that's true, then you couldn't really trust them to tell you they know that something is definitely bad
