The rate of decrease shown by mercury levels in brown trout (Salmo trutta) and perch (Perca fluviatilis) collected downstream to a wood pulp factory after a ban on the use of phenyl mercury in the pulp and paper industries was made effective in 1970 has been slow. Even though a river habitat was involved, it seemed to take about 15 years for levels of mercury in downstream fish to fall to those recorded in fish upstream to the wood pulp factory.
1970年纸浆和造纸行业禁止使用苯基汞后，在一家木浆厂下游采集的褐鳟（Salmo trutta）和鲈鱼（Perca fluviatilis）体内汞含量的下降速度一直很慢。尽管涉及河流栖息地，但下游鱼类体内的汞含量似乎需要大约15年才能降至木浆厂上游鱼类所记录的水平。
