In this study, mineral magnetic, particle size and geochemical analyses were conducted on intertidal sediments from the Yangtze Estuary to examine the feasibility of heavy metal concentrations normalization using magnetic techniques. Susceptibility of Anhysteretic Remanent Magnetization (χARM), the ratio of χARM to SIRM (Saturation Isothermal Remanent Magnetization) and susceptibility (χARM/SIRM and χARM/χ, respectively), and to a lesser degree, frequency dependent susceptibility (χfd), displayed significant correlations with the fine sediment fraction (<16 µm). The strong relationships between χARM and heavy metals can be explained by the role of particle size and iron oxides in controlling metal concentrations. This study demonstrates that χARM can be used to normalize for particle size effects as efficiently as common reference elements such as Al. Furthermore, the rapid and non-destructive nature of mineral magnetic measurement technique means that χARM has a considerable application value in environmental quality monitoring and related studies.
