从斯海尔德东部相对未受污染的地区采集的贻贝，被移植到斯海尔德西部污染地点，为期 21/2z 和 5 个月。确定了几个既定的压力指数，例如污染物累积、腺苷酸能量电荷（AEC）和状况指数。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，环境暴露改变了贻贝在有机体（缺氧生存时间）、生化（AEC）和分子（热休克蛋白合成）水平上对应激（即空气暴露和温度升高）的反应。评估环境污染的“压力方法”似乎是一种很有前途的方法，可以在常规参数（条件指数，AEC）仍保持不变的阶段揭示生物体的早期变化。
Sea mussels,Mytilus edulis, collected from a relatively unpolluted area of the Eastern Scheldt, were transplanted along contaminated sites of the Western Scheldt for 21/2z 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.
