Losses of Ca2+, Mg2+ and primary amines into waters between pH = 5 and 3 from eyed Chinook salmon eggs, Oncorhynchus tshawytscha , and gills excised from the freshwater, bivalve mollusc Anodonta californiensis were measured and compared to effluxes into distilled water. Sulfuric, nitric and hydrochloric acids were used. Even at pH = 5 losses of Ca2+ and Mg2+ from both biological systems occur at short times, minutes, and can exceed those found in water of higher pH (non-acid waters). Increasing acidity increases short term primary amine loss from both systems. For both divalent cation and amino acid losses gills of A. californiensis are more sensitive to acidity than eggs of O. tshawytscha .
测定了pH值在5至3之间时，来自大眼银大麻哈鱼（Oncorhynchus tshawytscha）鱼卵以及淡水双壳贝类加州无齿蚌（Anodonta californiensis）鳃中的Ca2+、Mg2+和伯胺进入水体的损失情况，并与它们在蒸馏水中的流出量进行了比较。使用了硫酸、硝酸和盐酸。即使在pH = 5时，两个生物系统中的Ca2+和Mg2+在短时间内（几分钟）就会发生损失，且损失量可能超过在较高pH值水体（非酸性水体）中的损失量。酸度增加会使两个系统中伯胺的短期损失增加。对于二价阳离子和氨基酸的损失，加州无齿蚌的鳃比大眼银大麻哈鱼的鱼卵对酸度更敏感。
