| الوصف: | The bioaccumulation of Cs-134 was studied in the shrimp Palaemon adspersus (Rathke, 1837) using dissolved or food pathways. The uptake and loss kinetics (following seawater and food uptake) were followed for 27 and 38 days, respectively. The steady state concentration factor (CFss) value of Cs-134 in the whole body of the shrimp was found to be 15 +/- 0.08. The loss kinetics of radiocesium was described by a two-component exponential model, with a biological half-life of 85.5 days for the whole body. The depuration kinetics of Cs-134 was best fitted to a single-component exponential model for both edible and inedible parts. The deputation kinetics of Cs-134 following exposure via pulse-chase feeding was also described by a two-component exponential model, with a biological half-life of 84.2 days. Assimilation efficiency (AE) was found to be 38.5%. Most of the radioactivity was accumulated in muscular tissues (the edible part) of the shrimp compared to the remaining soft parts. The average of the total body burden of Cs-134 eliminated with molting was .3 +/- 8.1. (C) 2014 Elsevier Ltd. All rights reserved. |
