long term effects of sunscreen

I'm interested to hear people's opinions on the safety of sunscreen, especially on children. Jantimot mentioned this a few days ago, and while Janti and I have very differing opinions on healthcare methods, I do agree that there have been some concerning studies conducted on the long term use of sunscreen. Will link a few PDFs later.

(My view at the moment is basically that solar radiation presents substantially greater risk, but we mitigate suncsreen use as much as possible by using long sleeves etc.)
