Fapas Water and Environmental Environmental Soil Chemistry Analytes Cadmium Lead Chromium Arsenic Barium Nickel Copper Zinc Mercury Concentration Ranges Volume Supplied (approx, after dilution) (approx) Dilution Required 6 – 8 g no dilution required 1.0 – 400 mg/kg 10 – 2000 mg/kg 10 – 500 mg/kg 1 – 500 mg/kg 30 – 2500 mg/kg 1 – 200 mg/kg 2 – 200 mg/kg 10 – 200 mg/kg 0.1 – 200 mg/kg Analytical data for Certification was obtained using USEPA SW846, 3rd edition methods 3050 (hot block) and 3051 (microwave) using nitric acid extraction. Analysis was carried out according to USEPA methods 6010 (ICP-EOS), 6020 (ICP-MS) and 7000 (AES). Note that nitric acid extraction is not as rigorous as aqua regia. If your laboratory method employs aqua regia to analyse soil samples for metals then these samples may not be suitable.
