Sea mussels, Mytilus edulis, collected from a relatively unpolluted area of the Eastern Scheldt, were transplanted along contaminated sites of the Western Scheldt for 2 1/2 and 5 months. Several established stress indices were determined such as accumulation of pollutants, adenylate energy charge (AEC), and condition index. Following field exposure, mussels were also subjected to an additional lethal or sublethal stress. The data show that environmental exposure alters the mussel's response to stress, viz., aerial exposure and increased temperature, at the organismal (anoxic survival time), biochemical (AEC), and molecular (heat shock protein synthesis) level. The "stress approach" to assessment of environmental contamination appears to be a promising method to disclose early changes in the organism at a stage when conventional parameters (condition index, AEC) remain still unchanged.
从东斯海尔德河相对未受污染区域采集的紫贻贝（Mytilus edulis），被移植到西斯海尔德河的污染区域，时长分别为2个半月和5个月。测定了几个既定的应激指标，如污染物积累、腺苷酸能量电荷（AEC）和状况指数。在野外暴露后，贻贝还受到额外的致死或亚致死应激。数据表明，环境暴露会在生物个体（缺氧存活时间）、生化（AEC）和分子（热休克蛋白合成）水平上改变贻贝对应激（即空气暴露和温度升高）的反应。在传统参数（状况指数、AEC）仍未改变的阶段，采用“应激方法”评估环境污染似乎是一种揭示生物早期变化的有前景的方法。
