Sunda（1994年，2000年）和Bruland等人（1991年）对痕量金属与浮游植物相互作用的评论批判性地分析了生物活性痕量金属（Mn、Fe、Co、Ni、Cu和Zn）在控制海洋环境中初级生产者生物活动方面的重要性，以及反过来，生物过程在调节痕量金属化学方面的重要性。生物活性微量金属的可用性，所谓的，因为它们参与光合电子传递（Raven et al.1999）和其他代谢过程，可以影响大量营养素的获得和同化，如C，N和P。我们在这里的目的不是对这些作者提出的信息进行另一次讨论，而是遵循本纲要的主题，我们将重点介绍浮游植物在压力环境中的生存状况。这些环境强调的观点，包括生物活性微量金属的基本营养素的可用性。我们试图强调的情况下，实现最大生产力的基础上大量营养素的可用性的潜力是有限的基本微量金属的可用性。当然，我们对“潜力”的评估通常基于提供足够的营养水平或最佳的物理生长条件，正如在富集瓶试验或实验室浮游植物培养期间经常发生的那样。因此，在自然环境中，浮游植物很可能经常存在于次优条件下，并且在任何给定的自然环境中，存在基于每个生物体当前营养需求的一系列营养限制。
Reviews of trace metal interactions with phytoplankton by Sunda (1994, 2000) and Bruland et al. (1991) have critically analyzed the importance of the bioactive trace metals: Mn, Fe, Co, Ni, Cu, and Zn in controlling biological activity of primary producers in the marine environment, and conversely, of the importance of biological processes in the regulation of trace metal chemistry. The availability of bioactive trace metals, so called because of their involvement in photosynthetic electron transport (Raven et al. 1999) and other metabolic processes, can affect the acquisition and assimilation of macronutrients such as C, N and P. Our purpose here is not to provide another discussion of the information presented by these authors, but rather, following the theme of this compendium, we will highlight the aspects of phytoplankton living in stressed environments. These environments are stressed from the point of view of essential nutrient availability including bioactive trace metals. We seek to highlight the instances where potential to achieve maximum productivity based on macronutrient availability is limited by the availability of essential trace metals. Of course, our evaluation of “potential” is frequently based on the provision of adequate nutrient levels or optimal physical growth conditions, as often occur during enrichment bottle assays or during the culture of phytoplankton in the laboratory. Therefore, it is quite possible that in the natural environment, phytoplankton frequently exist under suboptimal conditions, and that in any given natural environment, there exists a range of nutrient limitations based on each organism’s current nutrient requirements.
