Figure 4

Relative environmental availability of DDTs and DDT metabolites in Kyzylkairat soil, comparing selected BC strategy and AC-based strategy. The “ORBO” group represents amended soil with ORBO, “DARCO” denotes amended soil with DARCO, and “St” represents the selected strategy: amendment of soil by 2% of <150 µm Sargasso BC. Values correspond to the mean ± standard error (SE) (n = 4). Group mean values with superscript asterisks indicate statistical differences from the selected strategy (St) (<0.05: * < 0.01: ** < 0.001: ***) using variance analysis and a Dunnett post hoc test. Groups mean concentrations with different superscript letters (a, b) are statistically different (p < 0.05) from each other using a complementary variance analysis followed by a Tukey post hoc test on previously found significant groups using Dunnett’s test.
