The aim of this study was to compare the capability of "passive" and "active" biomonitoring to determine the environmental pressure. For this purpose, PAHs content and several biological responses in resident and caged mussels (Mytilus galloprovincialis) at five sampling sites (Rijeka Bay, Adriatic Sea) were analsed. Resident mussels were found better in reflecting the level of PAH loads at particular sites while only caged mussels could detect input of HMW PAHs. When data of each investigated parameter were compared separately, the majority of differences between resident and caged mussels' results were site-specific. Integration of biological response patterns expressed as Index of Biological Response (IBR) resulted with different sampling sites ranking for resident and caged mussels. Multiple Factor Analysis (MFA) based on integration of tissue PAH concentration and biological response revealed resident mussels as more powerful for detection of environmental pressure. The use of resident mussels is recommended as appropriate and less costly approach for monitoring the effect of pollution.
本研究的目的是比较“被动”和“主动”生物监测确定环境压力的能力。为此，分析了亚得里亚海里耶卡湾五个采样点的本地贻贝和笼养贻贝（Mytilus galloprovincialis）中的多环芳烃含量及几种生物学反应。发现本地贻贝在反映特定地点的多环芳烃负荷水平方面表现更佳，而只有笼养贻贝能够检测到高分子量多环芳烃的输入。当分别比较每个调查参数的数据时，本地贻贝和笼养贻贝结果之间的大多数差异是特定地点的。以生物反应指数（IBR）表示的生物反应模式的整合导致本地贻贝和笼养贻贝的不同采样点排名。基于组织多环芳烃浓度和生物反应整合的多因素分析（MFA）表明，本地贻贝在检测环境压力方面更有效。建议使用本地贻贝作为监测污染影响的合适且成本较低的方法。
