We analyse the Dioxin (TCDD) pollution of the Seveso (Milan, Italy) territory, seeking to statistically parametrize it in terms of Universal Multifractals. The data set contains the measurements collected from 1976 up to 1981. We apply the Double Trace Moment (DTM) technique in order to estimate both α (the degree of multifractality) and C 1 (the codimension of the mean field) and (with the help of spectral analysis) we also calculate H (the degree of non‐conservation of the process). We then discuss the effects introduced by statistical undersampling and network sparseness and provide a way to statistically correct for these effects. We conclude that the ground distribution of Dioxin shows clear multifractal features and can be classified as an unconditionally hard universal multifractal process.
