摘要

本文分析了来自西赤道大西洋（WEAO）的两种上层海洋鱼类didon eydouxii（上层豪猪鱼）和四翼飞鱼Hirundichthys affinis（四翼飞鱼）以及一种中上层海洋鱼类Howella atlantica（大西洋上层鲈鱼）的汞浓度，研究了它们与总长度的关系。汞的浓度差别很大，在麻蝇中含量最高。两种汞含量与体型呈中等正相关。这项研究提供了来自世界海洋组织的关于这些物种汞生物积累的第一个数据，并强调需要更大的样本量和更广泛的年龄范围，以更好地了解中上层食物网中的汞转移。

Mercury Concentration in Epipelagic and Mesopelagic Fishes from the Western Equatorial Atlantic Ocean.

We analyzed mercury concentrations in two epipelagic fish species Diodon eydouxii (Pelagic Porcupinefish) and Hirundichthys affinis (Fourwing Flyingfish) and one mesopelagic species Howella atlantica (Atlantic Pelagic Basslet) from the Western Equatorial Atlantic Ocean (WEAO), examining their relationship with total length. Mercury concentrations varied significantly, with the highest levels in H. affinis. Two species showed a moderate positive correlation between Hg levels and body size. This study provides the first data on Hg bioaccumulation in these species from the WEAO and highlights the need for larger sample sizes and broader age ranges to better understand mercury transfer in pelagic food webs.
