Boron Contents of German Mineral and Medicinal Waters and Their Bioavailability in Drosophila melanogaster and Humans.

Scope: Boron is a trace element that naturally occurs in soil, making mineral and medicinal water important contributors to overall intake. Thus, in a systematic screening, the mean boron concentrations of 381 German mineral and medicinal waters are determined.

Methods And Results: Boron concentrations in mineral and medicinal waters are analyzed by inductively coupled mass spectrometry (ICP-MS).

Lithium-Rich Mineral Water is a Highly Bioavailable Lithium Source for Human Consumption.

Scope: Lithium is an important trace element in human nutrition and medicine. Mineral and medicinal waters may represent a significant source of dietary lithium intake.

Methods And Results: The lithium concentration of 360 German mineral and 21 medicinal waters is determined.
