Assimilation and elimination of cesium by freshwater invertebrates, The
Freshwater invertebrates are important vectors of radioactive cesium 134Cs and 137CS) in aquatic food webs, yet little is known about their cesium uptake and loss kinetics. This study provides a detailed investigation of cesium assimilation and elimination by freshwater invertebrates. Using five common freshwater invertebrates (Gammarus lacustris, Anisoptera sp. nymphs, Claassenia sabulosa and Megarcys signata nymphs, and Orconetes sp.), a variety of food types (oligochaete worms, mayfly nymphs and algae) and six temperature treatments (3.5 to 30°C), the following hypotheses were tested: 1) ...
