Scientific research has characterized the effects of dredging, an underwater excavation process for navigational purposes or material extraction, and has shown its association with a number of chemical, physical and biological impacts. Due to this, much environmental management has been applied in the dredging industry in order to manage its detrimental effects. However, developing nations may have different approaches towards their dredging environmental management to compare to their companions with higher economic strength. Moreover, scientific evidence to make an informed decision is often lacking, hence affecting the number of research executed at these nations, limiting their efforts to preserve the environment. This paper reviews the dredging environmental impacts and its two important factors, dredging technology and sediment characteristic, that determine the magnitude of impacts through literature review, and discusses the need for a more integrated dredging environmental management to be developed for developing nations.
科学研究已对疏浚（一种出于通航目的或物料开采的水下挖掘作业）的影响进行了特征描述，并表明其与多种化学、物理和生物影响存在关联。因此，疏浚行业已实施了大量环境管理措施，以管控其有害影响。然而，与经济实力较强的国家相比，发展中国家在疏浚环境管理方面可能有不同的做法。此外，往往缺乏做出明智决策所需的科学依据，从而影响了这些国家开展的研究数量，限制了它们保护环境的努力。本文通过文献综述回顾了疏浚的环境影响及其两个重要因素——疏浚技术和沉积物特性，这两个因素决定了影响的程度，并讨论了为发展中国家制定更综合的疏浚环境管理措施的必要性。
