Geochemical Baseline Survey of the Environment

Figure 5.1 Example of a Geochemical Baseline Survey of the Environment (G-BASE) sample number defined by four key fields to give a unique sample identity.

Figure 5.3 Example of a Geochemical Baseline Survey of the Environment (G-BASE) random number list used for issuing site numbers with 8% of the numbers reserved for duplicates, replicates (sub-samples), standards and blanks. The blank column is used to record details of the date and sampbng pair assigned to each number.

Figure 5.8 Examples of duplicate-replicate plots from soil analyses from the Geochemical Baseline Survey of the Environment (G-BASE) project generated by an MS Excel macro (for the relationship of control samples, see Fig. 5.4). Note that the cited detection limits for Cu, U and I are 1.3, 0.5 and 0.5 mg/kg, respectively.
