In Agadir Bay, a study evaluated pollution biomarkers in the mollusk species Patella vulgata. Samples were collected seasonally from September 2021 to September 2022 at two distinct coastal sites within Agadir Bay: Cap Ghir and Anza Beach. Notable variations were observed in biomarkers like malondialdehyde, with a peak at 10.62 nmol/mg P in spring 2022 at Anza Beach. Catalase activity spiked in spring at 69.56 µmol/min/mg P for Cap Ghir and 72.73 µmol/min/mg P for Anza Beach. Acetylcholinesterase showed a decrease at 9.84 nmol/min/mg P in autumn at Anza Beach. Meanwhile, glutathione-S-transferase recorded an increase to 317.96 nmol/min/mg P at Cap Ghir in spring 2022. Using the Integrated Biomarker Response (IBR), these results were visualized, highlighting more stress in mollusks from Anza Beach compared to Cap Ghir. This research provides critical insights into the environmental effects on P. vulgata and potential conservation strategies.
在阿加迪尔湾，一项研究评估了贻贝物种 Patella vulgata 中的污染生物标志物。样本于 2021 年 9 月至 2022 年 9 月期间在阿加迪尔湾内两个不同的沿海地点（卡普吉尔和安扎海滩）季节性采集。在贻贝中，生物标志物如丙二醛（MDA）的变化显著，安扎海滩 2022 年春季的 MDA 峰值达到 10.62 nmol/mg P。卡普吉尔的过氧化氢酶活性在春季飙升至 69.56 µmol/min/mg P，而安扎海滩则为 72.73 µmol/min/mg P。乙酰胆碱酯酶在秋季安扎海滩下降至 9.84 nmol/min/mg P。与此同时，谷胱甘肽-S-转移酶在 2022 年春季卡普吉尔的记录增加到 317.96 nmol/min/mg P。利用综合生物标志物响应（IBR），这些结果可视化，突出显示了安扎海滩贻贝受到的压力大于卡普吉尔。这项研究深入了解了环境对 P. vulgata 的影响和潜在的保护策略。
