While it still a valuable discover, I think it's too early to make any conclusions yet due to fairly limited source.

This is just an analysis of some cups on a campus in India so I agree that it's interesting and worth looking at but possibly not directly comparable with products which meet EU / UK / USA food contact regulations.

Sample B seems to have vastly mode copper and manganese leaching out than the other samples.
