Using one analytical method, the Steinhauser team compared 18 rock-salt samples from six countries to examine how trace-element profiles vary among natural salts.

Six Countries
Samples came from Austria, Germany, Pakistan, Poland, Switzerland and Ukraine.
Some were commercially available rock-salt products.
Element List
Detected elements included Al, Ba, Br, Ca, Ce, Co, Cr, Cs, Eu, Fe, Hf, La, Mn, Rb, Sb, Sc, Sm, Sr, Ta, Tb, Th and Zn among others.
The authors specifically noted that some elements occurred only in individual samples.
Geological Origin and Product Variation
Although halite is the dominant mineral, accessory minerals and trace elements can vary among deposits.
Rock salts from different countries should therefore not be assumed to have identical chemical profiles simply because they share the same product name.
