已知双壳类具有从环境水中积累不同污染物的能力，因此可以作为生物指示剂。本文分析了蓝贻贝的某些生化和生理参数响应不同的石油产品浓度。在长期实验中，采用非侵入性监测方法，研究了暴露于不同水平石油产品的近岸带蓝贻贝的心率（HR）。在油浓度为8.0和38.0 mg/l时，观察到HR急剧上升。在较低浓度（0.4和1.9毫克/升）的影响下，贻贝的心率在第四天显著下降。在所有浓度下均观察到心脏活动的强烈波动。油处理6天后，对贻贝的组织取样以确定总脂质组成。低浓度的油产品在脂质组成中没有产生可靠的变化，而高浓度引起脂质组分（胆固醇和磷脂）的比例发生显着变化。
Bivalves have a known ability to accumulate different contaminants from ambient water and can therefore serve as bioindicators. The paper analyses certain biochemical and physiological parameters of blue mussels in response to varying oil product concentrations. The heart rate (HR) of blue mussels from the sublittoral zone exposed to different levels of oil products was investigated in a long-term experiment using non-invasive monitoring. A sharp rise in HR was observed at oil concentrations of 8.0 and 38.0 mg/l. A decreasing in mussel HR under the effect of lower concentrations (0.4 and 1.9 mg/l) was significant on the fourth day. Strong fluctuations of the cardiac activity were noted under all concentrations. After 6 days of oil treatment, tissues of the mussels were sampled to determine the total lipid composition. Low concentrations of oil products produced no reliable changes in the lipid composition whereas high concentrations induced significant changes in the ratio of lipid components (cholesterol and phospholipids).
