改性粘土作为一种低成本、高效率、环境友好型的抑藻剂，在我国得到了广泛的应用。由于在中国的成功，该技术近年来也获得了国际认可。然而，该技术的生态环境影响仍然是许多客户和政府机构关注的问题，这促使中国和许多其他国家的科学家评估其对非目标水生生物，水质和底栖环境的潜在影响。本文综述了实验室和现场的研究结果，表明MC不会伤害非目标水生生物，对水质和底栖环境没有负面影响。此外，研究结果表明，MC可以改变营养循环，减少水体中的藻类毒素。此外，研究人员还发现MC影响沉积环境中的包囊形成和萌发。该综述有望为中国乃至世界范围内利用粘土或MC缓解赤潮提供科学指导。
The application of modified clay (MC) to mitigate harmful algal blooms (HABs) is becoming a widespread practice in China because of its low cost, high efficiency and environmental friendliness. Due to its success in China, this technology has also gained international recognition in recent years. Nevertheless, the ecoenvironmental impacts of this technology still remain to be a concern to many customers and government agencies, which has motivated scientists in both China and many other countries to evaluate its potential effects on nontarget aquatic organisms, water quality and the benthic environment. This paper reviews the results from these studies both in the laboratory and in the field, which showed that MC does not harm nontarget aquatic organisms and has no negative impact on water quality or the benthic environment. Additionally, findings show that MC can alter nutrient cycling and reduce algal toxins in water bodies. Furthermore, researchers also found that MC affects cyst formation and germination in sedimentary environments. This review is expected to provide scientific guidance for mitigating HABs in China and worldwide using clay or MC.
