The health status of the commercial Tehuelche scallop Aequipecten tehuelchus from San Román and El Riacho in San José gulf (Patagonia, Argentina) was evaluated through biomarkers widely used in ecotoxicological applications. Natural levels of arsenic (As) and cadmium (Cd) were measured to determine their potential relationships with fluctuations of several oxidative stress biomarkers in the scallop. Oxidative biomarkers, such as catalase (CAT), glutathione S-transferase (GST), superoxide dismutase (SOD), metallothioneins (MT), reactive oxygen species (ROS), α-tocopherol (α-T), and lipid peroxidation (LPO) through thiobarbituric acid reactive substances (TBARS) and lipid radical (LR∙), were measured in gills, digestive gland, and muscle of Tehuelche scallop in winter (August 2015) and summer (January 2016). Levels of As and Cd and of most of the biomarkers (SOD, ROS, TBARS, and LR∙) showed strong seasonal variability in the three tissues. In general, the highest values were recorded in digestive gland. The Integrated Biomarker Response index indicated that the most stressed condition of A. tehuelchus was in summer in San Román. Additionally, the Integrated Biomarker Response index showed a strong relationship among tissues and As and Cd accumulation. This kind of approach could be used as an integrated tool to identify the health status of scallop A. tehuelchus from San José gulf.

来自圣何塞湾（阿根廷巴塔哥尼亚）的商业海洋扇贝中的多种生物标志物方法，用于健康状况评估。

通过广泛用于生态毒理学应用的生物标志物，评估了圣何塞海湾（阿根廷巴塔哥尼亚）的圣罗曼和埃尔里亚乔市商业化扇贝扇贝tehuelchus的健康状况。测量了砷（As）和镉（Cd）的自然水平，以确定它们与扇贝中几种氧化应激生物标记物波动的潜在关系。氧化生物标志物，例如过氧化氢酶（CAT），谷胱甘肽S-转移酶（GST），超氧化物歧化酶（SOD），金属硫蛋白（MT），活性氧（ROS），α-生育酚（α-T）和脂质过氧化（LPO）通过硫代巴比妥酸反应物质（TBARS）和脂质自由基（LR∙）在冬季（2015年8月）和夏季（2016年1月）对in鱼扇贝的g，消化腺和肌肉进行了测量。三种组织中的As和Cd以及大多数生物标志物（SOD，ROS，TBARS和LR∙）的水平均表现出强烈的季节性变化。通常，最高值记录在消化腺中。综合生物标志物反应指数表明，A。tehuelchus的压力最大，是夏季在圣罗曼。此外，综合生物标志物反应指数显示出组织与砷和镉的积累之间有很强的关系。这种方法可以用作识别圣何塞海湾扇贝A. tehuelchus健康状况的综合工具。tehuelchus在夏天在圣罗曼。此外，综合生物标志物反应指数显示出组织与砷和镉的积累之间有很强的关系。这种方法可以用作识别圣何塞海湾扇贝A. tehuelchus健康状况的综合工具。tehuelchus在夏天在圣罗曼。此外，综合生物标志物反应指数显示出组织与砷和镉的积累之间有很强的关系。这种方法可以用作识别圣何塞海湾扇贝A. tehuelchus健康状况的综合工具。
