Are Tampons dangerous in Switzerland

Not long ago I heard that tampons from many different places had lead and arsen in them and may effect your health however when I searched if that’s the case in Switzerland I saw many contradicting statements and articles Now I know this isn’t a new topic but it’s new for me Does anyone know if there have been any tests? I also wonder what ppl think abt the whole topic are there ppl who stopped using them Bcs of that?
