NGR BC ISE stream sediments and moss mats (F)

NGR British Columbia stream samples (sediments and moss mats), analysis by ion-selective electrode for F.

General Methodology:

Decomposition: Na2CO3 – KNO3 fusion; H2O leach.  Analysis: citric acid added and diluted with water; fluorine determined with specific ion electrode.  After Ficklin (1970).
