Vegetable Garden Study, Augusta Forestry Center

Presentation reports a 2003 field study at the Augusta Forestry Center comparing vegetables grown in a floodplain garden and a control garden. Soil total mercury ranged from about 0.03 mg/kg (control) to 20–55 mg/kg (floodplain). Vegetable samples were analyzed; most plant Hg was below detection (<0.0028 µg/g), with several carrot samples above LOQ but <0.19 µg/g.
