Please note that B – Inorganics - Full participation comprises 7 separate samples (Standard solutions: 6, 8, 10, 12, 16, 17. Soil sample: 3b). To view the breakdown of the analytes per individual sample, please see the CONTEST Scheme Description. For the soil sample 3B, measurable levels of all analytes may not be present for every round. When the consensus value (RMean) falls below the cut-off levels listed above, a z score is provided for information only and should be interpreted with care.
