This study extends our knowledge of the bioaccumulation of polycyclic aromatic hydrocarbons (PAHs) in marine organisms and investigates its possible determinants. PAH levels were measured in Solea solea tissue and in marine sediments collected from three areas of the northern Adriatic Sea characterized by different anthropic impacts (Venetian Lagoon, Po Delta, and fishing grounds off Chioggia). The possibility of differential PAH bioaccumulation in different tissues (muscle, liver and gills) was investigated by seeking relationships between mean individual and total PAH concentrations in tissue and sediment samples, the physicochemical properties of PAHs (rings and K), and some key biological variables (lipid content of tissues, body size, habitat). The present study demonstrated that the lipid content might not be the only determinant of PAH bioaccumulation in common sole tissues. The habitat characteristics, the tissue types and some physicochemical properties of compounds were closely related to PAH bioaccumulation.
本研究扩展了我们对多环芳烃(PAHs)在海洋生物体内生物积累的认识,并研究了其可能的决定因素。在来自亚得里亚海北部三个地区(威尼斯泻湖、波河三角洲和基奥贾外的渔业区)的软骨鱼属组织和海洋沉积物中测量了多环芳烃的水平,这些地区的人为影响程度不同。通过研究组织和沉积物样本中个体和总多环芳烃浓度之间的关系、多环芳烃的理化性质(环数和 K 值)以及一些关键生物学变量(组织的脂质含量、体型、栖息地),研究了不同组织(肌肉、肝脏和鳃)中多环芳烃生物积累的差异。本研究表明,脂质含量可能不是普通欧鳎组织中多环芳烃生物积累的唯一决定因素。栖息地特征、组织类型和化合物的某些理化性质与多环芳烃的生物积累密切相关。
