Set amalgam, annealed for twelve days, was cut with water cooling and sucked into eight dental units (Systematica 1062 T), equipped with an amalgam separator (Multisystem Type 1). Disinfection of the suction devices was performed with seven commonly used disinfectants according to the manufacturer's guidelines. Rinsing with water served as a control in the last experimental series. The waste water was collected at the beginning of the experiments and after disinfection. Repeating the experiments for seven times resulted in 112 specimens that were analyzed by atomic absorption spectrophotometry. The use of Green & Clean M2 and S & M matic resulted in very low releases of mercury. Disinfection with Alprojet D and Alprojet DD M2 was comparable with the control group. The release of mercury was significantly increased, if compared to Green & Clean and S & M matic (p < or = 0.05). The use of Orotol Ultra, Aseptoclean 2, and Tiutol resulted in significantly higher releases of mercury, if compared to all other disinfectants (p < or = 0.05). Disinfectants containing oxidizing agents provoke an increasing release of mercury, thus accumulating the amounts of mercury in the general environment.
将经过十二天退火处理的银汞合金在水冷条件下切割，并吸入八个配备汞合金分离器（Multisystem Type 1）的牙科设备（Systematica 1062 T）中。根据制造商的指导方针，使用七种常用消毒剂对抽吸装置进行消毒。在最后一个实验系列中，用水冲洗作为对照。在实验开始时和消毒后收集废水。重复实验七次，得到112个样本，通过原子吸收光谱法进行分析。使用Green & Clean M2和S & M matic导致汞的释放量非常低。用Alprojet D和Alprojet DD M2消毒与对照组相当。与Green & Clean和S & M matic相比，汞的释放量显著增加（p≤0.05）。与所有其他消毒剂相比，使用Orotol Ultra、Aseptoclean 2和Tiutol导致汞的释放量显著更高（p≤0.05）。含有氧化剂的消毒剂会导致汞的释放增加，从而在一般环境中积累汞的量。
