摘要

全球对塑料的需求增长主要是因为它们的多功能性、重量轻、强度和成本效益。非洲在塑料垃圾管理不善导致环境中的塑料问题方面排名第一。尽管如此,塑料通过降解和破碎主要来自人为来源的塑料碎片来生产微塑料。微塑料已经在自然环境中无处不在,陆地环境是其主要来源。微塑料吸附和浓缩持久性有机污染物的倾向对水生和领土环境中不同热带水平的生物体的健康产生了潜在影响。因此,微塑料的命运正日益成为全球关注的问题。尽管对微塑料对环境的影响进行了大量的全球研究,但关于微塑料在非洲水生生态系统中的发生、分布和相关健康影响的数据不足。回顾了2000-2001年的研究文章,总结了目前关于微塑料的发生和分布、用于检测和量化微塑料的分析方法、相关的健康影响以及通过政府政策在非洲禁止使用塑料的缓解措施的知识。所提出的研究结果为未来的研究提供了一个平台,重点关注非洲水生环境中吸附和浓缩的持久性有机污染物对微塑料的相关影响。有了这些证据,政策制定者将对非洲塑料的未来做出更明智的决定。我们建议通过研究微塑料在非洲水生环境中的命运和潜在生态影响来改善信息并扩大知识。

Micro-plastic pollution in aquatic environment in Africa: status, challenges and emerging opportunities
The global demand of plastics has increased majorly because of their versatility, light weight, strength and cost-effectiveness. Africa is ranked top in mismanagement of plastics waste resulting to plastic problem in the environment. Nevertheless, plastics produce micro-plastics through degradation and fragmentation of plastic debris largely from anthropogenic sources. Micro-plastics have become ubiquitous in the natural environment and terrestrial environment is the major source. The propensity of micro-plastics to adsorb and concentrate persistent organic pollutants (POPs) provides potential health effects in the different tropical levels of organisms both in aquatic and territorial environments. Thus, the fate of micro-plastics is increasingly becoming a global concern. Despite the numerous global studies on the impact of micro-plastics in the environment, there is insufficient data available on the occurrence, distribution of micro-plastics and associated health effects in aquatic ecosystems in Africa. The reviewed research articles from 2000 – 2021 provide a summary of the current knowledge on the occurrence and distribution of micro-plastics, analytical approaches used to detect and quantify micro-plastics, associated health effects and mitigation measures through government policy to ban plastic use in Africa. The findings presented, provide a platform for future research to focus on the associated effects of adsorbed and concentrated persistent organic pollutants on micro-plastics in aquatic environments in Africa. With the evidence presented policy makers will make more informed decision on the future of plastics in Africa. We recommend improving information and expanding knowledge through research on the fate and potential ecological impact of micro-plastics in aquatic environments in Africa.
