The availability of the five chemical fractions, i.e., exchangeable (F1), carbonate-bound (F2), Fe/Mn oxide-combined (F3), organic matter-complexed (F4), residual (F5), of three heavy metals (Cu, Zn, and Cd), has been investigated by way of a sequential extraction technique based on the characteristics of the coastal soils developed from alluvial deposits, in order to analyze the relationship of the formation and development of coastal soils. The results showed that F1 and F5 of Cu, Zn, and Cd accounted dominantly for 9.11%, 2.74%, and 20.37%, and for 39.49%, 45.18%, and 32.43% of total heavy metal contents, respectively, indicating the order of availability and mobility: Cd > Cu > Zn. F2, F3, and F4 of HMs also featured prominently in the behaviors of heavy metals. Random measurement errors from both sampling and analysis were demonstrated by SAX to be well within the control target of 20% and, therefore, of no impediment to the geochemical interpretation of the data. Significant positive correlation was found between certain fractions of heavy metals and some soil properties. Some negative correlation was also found. The findings were helpful to the soil remediation, fertility adjustment, and plant cultivation.
