人类活动在陆地上产生的大部分废水经过不同程度的处理后排入水生环境。这种废水中所含的污染物，特别是氮、磷、金属和碳氢化合物，在沿海沃茨中积累，造成污染，扰乱海洋生态系统的平衡。生物修复是一种可持续的处理方法，通过使用生物有机体，越来越多地关注海藻，来中和这些污染物，从而减少这种污染对海洋环境的影响。海藻种植的最新研究和商业发展证明了海藻修复陆地和沿海水产养殖、城市和农业径流以及工业设施中营养物质和金属的潜力。在这一章中，我们提供了一些例子，比如种植石莼来处理陆地水产养殖中的营养物质，种植海带来修复近岸沿海环境中的人为营养物质，最后是海藻生物量来隔离工业废水中的溶解金属。这些例子表明，尽管大规模实施这项技术存在技术挑战，但基于海藻的生物修复提供了一个以生态友好方式有效清洁污染海水的机会。此外，这些实施例证明了生产用于基于海藻产品的生长工业的有价值的商业作物的显著优点。
The majority of wastewater produced on land by anthropogenic activities is discharged, with varying levels of treatment, into the aquatic environment. The contaminants contained in this wastewater, in particular nitrogen, phosphorus, metals, and hydrocarbons, accumulate in coastal waters, causing pollution and disturbances in the balance of marine ecosystems. Bioremediation is a sustainable treatment method that reduces the impact of this pollution on the marine environment by using biological organisms, with an increasing focus on seaweeds, to neutralize these contaminants. Recent research and commercial developments in seaweed cultivation demonstrate the potential of seaweeds to remediate nutrients and metals from land‐based and coastal aquaculture, urban and agricultural runoff, and industrial facilities. In this chapter, we provide examples of the cultivation of Ulva to treat nutrients from land‐based aquaculture, the cultivation of kelp to remediate anthropogenic nutrients in the nearshore coastal environment, and finally seaweed biomass to sequester dissolved metals in industrial effluents. These examples show that despite the technical challenges in implementing this technology at scale, seaweed‐based bioremediation provides an opportunity to effectively clean polluted seawater in an ecologically friendly manner. Additionally, these examples demonstrate the significant advantage of producing a valuable commercial crop for use in a growing industry based on seaweed products.
