本文综述了具有生物活性的痕量金属--锰、铁、钴、镍、铜和锌的海洋化学组成；结合现场数据和实验室浮游植物培养-痕量金属研究的结果，推测了这些痕量金属对海洋浮游生物产量和物种组成的潜在影响。大多数实地研究都集中在单一金属的影响上。然而，我们认为多种痕量金属之间的协同和拮抗作用在海洋中可能是非常重要的。可能被证明特别重要的微量金属拮抗作用是铜与潜在的生物限制金属铁、锰和锌之间的拮抗作用。这些对立的相互作用可能对远离陆地输入的开阔海洋区域的生物生产力产生最大影响，例如太平洋和南冰洋偏远的高营养区域。在这些海洋地区出现的痕量金属-生物群相互作用的图景是，生物强烈影响所有这些具有生物活性的痕量金属的分布和化学形态。许多具有生物活性的痕量金属及其形态也可能影响初级生产力、物种组成和营养结构的水平。未来的研究应该更全面地考虑具有生物重要性的痕量金属的相互作用效应。
We present an overview of the oceanic chemistries of the bioactive trace metals, Mn, Fe, Co, Ni, Cu, and Zn; we combine field data with results from laboratory phytoplankton culture-trace metal studies and speculate on the potential influences of these trace metals on oceanic plankton production and species composition. Most field studies have focused on the effects of single metals. However, we propose that synergistic and antagonistic interactions between multiple trace metals could be very important in the oceans. Trace metal antagonisms that may prove particularly important are those between Cu and the potential biolimiting metals Fe, Mn, and Zn. These antagonistic interactions could have the greatest influence on biological productivity in areas of the open ocean isolated from terrestrial inputs, such as the remote high nutrient regions of the Pacific and Antarctic Oceans. The emerging picture of trace metal-biota interactions in these oceanic areas is one in which biology strongly influences distribution and chemical speciation of all these bioactive trace metals. It also seems likely that many of these bioactive trace metals and their speciation may influence levels of primary productivity, species composition, and trophic structure. Future investigations should give more complete consideration to the interactive effects of biologically important trace metals.
