Biological and fishery features of Panopea sp. clams have been studied in northwest Mexico because of their importance for human consumption. However, the content of pollutants in their tissues, along with their implications have not been addressed yet. The concentrations of cadmium (Cd), copper (Cu), mercury (Hg), and zinc (Zn) in soft tissues of Panopea generosa and P. globosa clams were examined in this region by atomic absorption spectroscopy. The metal concentrations (µg/g wet weight) ranged from 6.5 to 14.2, 0.97-8.09, 0.60-1.18, and 0.01-0.07, for Zn, Cu, Cd, and Hg, respectively. This study proposes that metal presence is related to weathering, upwelling, and drainage from adjacent agricultural lands to the coast. According to the Official Mexican Standard (NOM-242-SSA1-2009) and the World Health Organization (WHO, 2022), the metal content in siphon tissue indicates safe levels for human consumption.
由于其对人类消费的重要性，墨西哥西北部对Panopea属蛤蜊的生物学和渔业特征进行了研究。然而，其组织中的污染物含量及其影响尚未得到研究。通过原子吸收光谱法检测了该地区Panopea generosa和P. globosa蛤蜊软组织中镉（Cd）、铜（Cu）、汞（Hg）和锌（Zn）的浓度。锌、铜、镉和汞的金属浓度（微克/克湿重）分别为6.5至14.2、0.97 - 8.09、0.60 - 1.18和0.01 - 0.07。本研究表明，金属的存在与风化、上升流以及相邻农田向海岸的排水有关。根据墨西哥官方标准（NOM - 242 - SSA1 - 2009）和世界卫生组织（WHO，2022），虹吸管组织中的金属含量表明对人类消费来说处于安全水平。
