dc.description.abstract | Bioconcentration of 4-tert-Octylphenol (OP) in freshwater algae Chlorella vulgaris was investigated by considering the effects of algal growth and exudate excretion. The OP uptake in algae was approximately 113 mg kg(-1) after 24 h, and the uptake rate constant was estimated as 2.4 x 10(4) L kg(-1) d(-1). The OP sorption onto exudates reduced OP bioavailability to C. vulgaris to 11% after 24 h, with a sorption coefficient of 9.7 x 10(3) L kg(-1). The elimination of OP by algae growth (0.80 d(-1)) was dominant over real elimination (0.60 d(-1)). The calculated bioconcentration factor of OP in C. vulgaris following uptake and elimination rate constants was 4.0 x 10(4) L kg(-1). Further, bioaccumulation of OP in Daphnia magna was investigated by considering both aqueous and dietary (C. vulgaris) exposures. Uptake and elimination rates of OP via water were 1.6 x 10(4) L kg(-1) d(-1) and 0.95 d(-1), respectively, while ingestion rate and assimilation efficiency via diet were 0.41 d(-1) and 58%, respectively. The OP accumulation in D. magna predominantly occurred via water (63%) relative to diet (37%), resulting in a bioaccumulation factor of 2.7 x 10(4) L kg(-1). The estimated trophic transfer factor was 0.25, suggesting that OP biomagnification was unlikely in the C. vulgaris-D. magna trophic relationship. | - |
