However, it is difficult to know when the thermodynamic equilibrium between the radionuclides present in the waste packages and the surrounding geological environment will be established. Kinetics of selenium redox reaction are slow (Foster et al., 2003). Se species are often found in redox disequilibrium and oxidized species might persist in reducing environments. Selenite concentration in reducing conditions representative for Boom Clay will be governed by sorption followed by a reduction–precipitation mechanism, while selenate is likely not sorbed nor easily reduced (Bruggeman et al., 2002). The study of selenatemigration in Boom Clay requires thus a higher priority, as it might be the most mobile selenium species in the host rock.

然而,很难知道何时废物(存储)库中放射性核素和周围地质环境之间的热力学平衡将会建立。硒氧化还原反应的动力学很缓慢 (Foster等,2003)。Se物种通常发现在氧化还原不均衡中,而氧化物种可能在还原条件下保留。在还原条件下亚硒酸盐的浓度由代表性Boom粘土的吸附来控制,吸附遵循还原-沉淀机理(机制),而硒酸盐可能既不被吸附也不易被还原(Bruggeman等,2002)。因此Boom粘土上硒酸盐迁移的研究显得尤为迫切,因为它可能是(认识)母岩中大多数硒物种迁移的根源所在。
