Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous pollutants of the marine environment, arising predominantly from petrochemical contamination and pyrogenic sources. A biomarker of PAH exposure was employed in a field study (South West, Spain) in both captured (indigenous) and deployed (caged) shore crabs (Carcinus maenas) in the chronic PAH-exposed Bays of Algeciras and Gibraltar (from associated harbour and boating activity) compared to a relatively 'clean' site (Cadiz). Metabolite fluorescence was attributed to the following key priority PAH groups; naphthalenes (NAPs), pyrenes (PYRs) and benzo[a]pyrenes (BAPs). Temporal variability was assessed using deployed populations over an eight week period. Petrogenic and pyrogenic PAH contamination (as an indicator of the PAH type) was demonstrated using a ratio between FF(BAP + PYR)/FF(NAP). Physiological assessments from deployed crabs demonstrated both physiological and cellular alterations as shown by reduced heart rates (at rest) and increased cellular stress in crabs from the PAH contaminated sites.
多环芳烃（PAHs）是海洋环境中普遍存在的污染物，主要来源于石化污染和热成因源。在西班牙西南部的一个野外研究中，使用了一种 PAH 暴露的生物标志物，比较了在长期受到 PAH 暴露的阿尔赫西拉斯湾和直布罗陀湾（来自相关的港口和划船活动）中捕获的（本地）和投放的（笼养）岸蟹（Carcinus maenas），以及一个相对“清洁”的地点（加的斯）。代谢物荧光归因于以下关键优先 PAH 组：萘（NAPs）、芘（PYRs）和苯并[a]芘（BAPs）。使用投放的种群在八周的时间内评估了时间变化。使用 FF（BAP + PYR）/FF（NAP）比值证明了生源和热成因 PAH 污染（作为 PAH 类型的指标）。来自受 PAH 污染地点的螃蟹的生理评估表明，螃蟹的心率（休息时）降低和细胞应激增加表明存在生理和细胞变化。
