虹鳟鱼对~（203）Hg标记甲基汞的清除符合双指数方程。甲基汞的生物半衰期从202到516天不等，取决于保留剂量和水温。蛋白质结合甲基汞浓度的增加导致生物半衰期的显着减少。在0.5到4之间？C甲基汞的排泄率约为1.5倍（516？83 d）比16-19？C（348？78 d）。
Elimination of 203Hg-labelled methylmercury by rainbow trout, studied by whole body counting, followed a bi-exponential equation. The biological half-time of methylmercury varied from 202 to 516 d, depending on the retained dose and water temperature. An increase in the concentration of protein-bound methylmercury caused a significant decrease in the biological half-time. Between 0.5 and 4?C the excretion rate of methylmercury was about 1.5 times longer (516 ? 83 d) than at 16-19?C (348 ? 78 d).
