Abstract

Accumulation of heavy metals in agricultural soils continues to be a worrying problem, such as chromium. Chromium may become contaminants in the soil and were suspected mobilized to food crops such as green spinach (Amaranthus hybridus). Bioavailability of the heavy metal speciation in spiked soil can be carried out by sequential extraction method by Tessier with different reagents to obtain five fractions, exchangeable, bound to carbonate, bound to Fe/Mn, bound to organic matter, residual and analysed by AAS. A. hybridus were harvested after 8 weeks, destructed by wet destruction and analysed with ICP-MS. Results showed the highest distribution in organic, Fe-Mn, and residual phases with percentage concentration 61.33% ± 0.013, 26.88% ± 0.04, 7.55% ± 0.012. Addition of chromium made biomass of plant decreased and its accumulation detected in root > stem > leaf with transfer and bioconcentration factor less than 1 meaning A.hybridus has potential as chromium accumulator.
