Response of toxic metal distributions and sources to anthropogenic activities and pedogenic processes in the Albic Luvisol profile of northeastern China
The results showed that SOM content was higher in horizon A, whereas mineral matrix elements Al, Fe, and Mg contents were higher in horizon B. Ca and P contents gradually decreased with soil depth due to the influence of fertilizer. Three types of trace element concentration profiles were identified: (1) decrease with depth for Cd and Hg
