In fact no. The parent comment is right in emphasizing the "exposure to concentrations equivalent to accumulations over several days and sources". So while your point 1. is technically true, it comes with the caveat of heavy concentrations. We know of thousands of "factors" that become dangerous or toxic in big concentrations but are innocuous or even beneficial in small doses. I'm not saying that plastic is either of these but to leave out the dose concentration is clearly misrepresenting from your part. So I don't know if you haven't read the article till the end (because this caveat of the concentration comes later after the sensational part you emphasized) or you are purposely trying to mislead others. The discrepancy of their result ("three-quarters of cultured embryonic kidney cells had died") with reality also clearly points to something very wrong with this study. That high level of cell mortality is not observed anywhere in reality.
