Uptake rate constant (k1), elimination rate constant (k2), bio-enrichment factor (BCF), and biological half-life (B1/2) were characterized based on the two-compartment model by nonlinear cure fitting. Under our experimental conditions, the uptake rate constant (k1) and BCF were decreased with the increase of the concentration of As3+, while the elimination rate constant (k2) was not distinctly related. The maximal metal contents in test organism (CAmax) at steady-state were in the linear proportion to As3+ concentrations through short exposure(R2=0.926 7). Elimination of inorganic arsenic from C. farreri was rapidly and completely; the elimination reached to 84.17 % after 30 days. Our results suggest that C. farreri cultivated in the second level of sea water quality standard should be safe. %K Chlamys farreri %K Inorganic arsenic %K Bio-concentration %K Elimination
