AbstractIntercropping technology provides income for owners of contaminated soil without increasing environmental risk. Therefore, intercropping of arsenic (As) hyperaccumulator Pteris vittata L. with economic crops is nowwidely utilized in slightly or moderately As-contaminated farmlands. However, the mechanisms for As mobilization and absorption within the intercropping system are still unclear. To clarify As mobilization and absorption within an intercropping system, portable X-ray fluorescence spectrometry and sequential extraction were utilized to detect the spatial distribution and speciation of As in an intercropped system of P. vittata and cash crop mulberry (Morus alba L.). Compared with the P. vittata monoculture, P. vittata intercropping had higher As concentration, which may have been caused by the efficient exploitation of a greater As source in soil. Compared with the M. alba monoculture, M. alba intercropping had lower As concentration, which may have been caused by the As depletion by P. vittata roots. Spatial distribution of As in the soil indicated a "valley" around the P. vittata roots in both monocultured and intercropped systems, implying that As was depleted around the P. vittata roots. Continuous As extraction confirmed that both P. vittata monoculture and P. vittata and M. alba intercropping can efficiently control the risk of As soil contamination. Moreover, the properties of M. alba leaves were further studied. Mulberry leaves in the intercropping system satisfied the national feed standards. Therefore, intercropping presents a safe utilization mode for As-contaminated soil and can increase the income from silkworm-rearing M. alba leaves, without extra environmental risk.
