Table 5 Correlation matrix of Pearson correlation coefficients for the concentrations of major chemical components and sorbed metals of the studied particle types in the sample LB. Correlation coefficients showing high correlation (−0 50 > r > 0.50) are highlighted with italics. Between 14 and 32 particles was studied by point chemical analysis (TEM-EDS) within the studied particle type groups. *Although the correlation coefficient suggested a strong relationship, it was influenced by a few outlier data
