In the present study, we evaluated the biological response of Achirus lineatus to water accommodated fraction (WAF) of light crude oil (American Petroleum Institute gravity 35°) during a sub-chronic bioassay (14 and 28 days) at two different concentrations: 5% v/v (1.20 µg∙L expressed as total polycyclic aromatic hydrocarbons [∑25 PAH]) and 10% v/v (6.61 µg∙L [∑25 PAH]). The responses were evaluated through the biomarker response index (BRI), the integrated biomarker response (IBRv2) and the bioconcentration factor (BCF). The results showed an increase in biological response in relation to WAF concentration and exposure time, which resulted in a slight and moderate disturbance in the basal condition and bioconcentration level of metals (Pb > Ni > V > Cd) in fish tissue. Results in the present study denote that flatfish such as A. lineatus may be negatively influenced by spilled light crude oil.
在本研究中，我们评估了 Achirus lineatus 对线状原油（美国石油学会比重 35°）水可溶部分（WAF）的生物反应，在两个不同浓度下进行了亚慢性生物测定（14 和 28 天）：5%v/v（1.20μg·L 表示总多环芳烃[∑25 PAH]）和 10%v/v（6.61μg·L [∑25 PAH]）。通过生物标志物反应指数（BRI）、综合生物标志物反应（IBRv2）和生物浓缩因子（BCF）评估了这些反应。结果表明，生物反应与 WAF 浓度和暴露时间呈正相关，这导致鱼类组织中金属（Pb>Ni>V>Cd）的基础状况和生物浓缩水平出现轻微和中度干扰。本研究结果表明，类似 A. lineatus 的比目鱼可能会受到溢油的负面影响。
