Isoscapes of the annual mean precipitation tritium activity in the Adriatic–Pannonian region

Tritium is an important tracer in hydrological sciences and a prerequisite for its applications is to know the spatial and temporal changes of tritium activity in precipitation.

Do we have the tools to see where our bottled water comes from?

Not all bottled water is equal, neither in its elemental, nor in its isotope composition. We determined where the bottled water we drink originates from and does it really comply with all the standards put in place.
