Ocean acidification impacts the physiology of crustaceans as well as marine calcifiers although most of the hitherto studies has focused on calcifiers. Bioconcentration of elements in a marine animal depends on seawater chemistry and the animal's physiology. Here we studied biokinetics and body distribution of Ag in Baltic shrimp Palaemon adspersus for 47 days by using radiotracer method (^110mAg). The bioconcentration of ^110mAg was assessed under three pCO₂ levels: 370, 795 and 1634 μatm. Uptake rate constants of ^110mAg were inversely related to pH (3.1 at pH: 8.1, 4.2 at pH: 7.8 and 4.9 at pH: 7.5). A higher percentage of Ag accumulated in edible parts in the shrimps reared in acidified seawater compared to control. The moulting frequency was significantly higher in acidified seawater conditions compared to the control condition. The results of this study suggest that seawater acidification may partly modify Ag bioconcentration in Baltic shrimp Palaemon adspersus as well as energy-demanding physiological processes like moulting.

海洋酸化影响甲壳动物以及海洋钙化剂的生理，尽管迄今为止大多数研究都集中在钙化剂上。海洋动物中元素的生物浓缩取决于海水化学和动物的生理。在这里，我们研究了在巴尔虾生物动力学和身体的Ag的分布长臂adspersus通过使用放射性示踪剂方法（47天^110米AG）。在三个p CO ₂水平下评估了^110m Ag的生物浓度：370、795和1634μatm。吸收率常数为^110mAg与pH呈反相关（pH：8.1时为3.1； pH：7.8时为4.2； pH：7.5时为4.9）。与对照相比，在酸化海水中饲养的虾中可食部分中积累的Ag百分比更高。与对照条件相比，酸化海水条件下的换羽频率明显更高。这项研究的结果表明，海水酸化可能会部分改变波罗的海虾Pala鱼的Ag的生物浓度，以及诸如换羽等对能量要求很高的生理过程。
