The photo of the label is not in focus but Googling the items shows it has a Proposition 65 warning about the product containing chemicals with the potential to cause cancers.
I am sure if you were to wash them in water containing some radium, it would counteract any potential carcinogens chemicals in the plastic.
It's hard to see what it is that you're referring to in your images. I've tried to magnify what I assume to be the relevant part though:

I'm not sure why the sticker gives you cause for concern.
Are you worried because the beaker is made in China? If so, why?
If not, can you explain what is your cause for concern please?
