无机汞的辛醇-水分配随着硫化物的增加而减少，支持预测中性Hg-S物种随着硫化物的增加而减少的模型。这些结果有助于解释汞的可用性降低，以甲基化细菌在硫化物的条件下，和硫化物和甲基汞之间的反比关系在沉积物中观察到。
The octanol-water partioning of inorganic mercury decreased with increasing sulfide, supporting a model that predicts decreased fractions of neutral Hg-S species with increasing sulfide. These results help explain the decreased availability of Hg to methylating bacteria under sulfidic conditions, and the inverse relationship between sulfide and methylmercury observed in sediments.
