Hyperaccumulation of nickel by Arenaria rubella (Caryophyllaceae) from Washington State

The nickel concentration of whole plants of Arenaria rubella collected on dunite, Skagit County, Washington, U.S.A., is reported as 1360 μg g⁻¹ (dry weight), compared with only 2.7 μg g⁻¹ for specimens collected on shale, Jefferson County. This is the first hyperaccumulator of nickel reported from n...

Description
Summary:The nickel concentration of whole plants of Arenaria rubella collected on dunite, Skagit County, Washington, U.S.A., is reported as 1360 μg g⁻¹ (dry weight), compared with only 2.7 μg g⁻¹ for specimens collected on shale, Jefferson County. This is the first hyperaccumulator of nickel reported from northwestern North America. High concentrations of chromium, cobalt and iron at 213, 33.5 and 28,900 μg g⁻¹ respectively, in plants from dunite contrast with low values (3, 0.49 and 600 μg g⁻¹) in samples from shale.
