NGR BC AAS stream sediments and moss mats (As)

NGR British Columbia stream samples (sediments and moss mats), analysis by atomic absorption spectroscopy (AAS) for As.

General Methodology:

Add 2 ml KI and dilute HCl to 0.8M HNO3 – 0.2M HCl.  2 ml of borohydride solution is added to produce AsH3 gas which is passed through a heated quartz tube in the light path of an atomic absorption spectrophotometer.  After Aslin (1976).
