• TITLE: Occurrence and Distribution of Microplastics in African Aquatic Ecosystems: Part 1—Freshwater Systems

  AUTHORS: Thies Thiemann

  KEYWORDS: Plastic Pollution, Microplastics, Freshwater Environment, Wastewater Treatment Plants, Africa

  JOURNAL NAME: Journal of Environmental Protection, Vol.17 No.10, October 14, 2026

  ABSTRACT: Microplastics are ubiquitous in aquatic and terrestrial environments worldwide and have emerged as a major environmental concern. This manuscript reviews the literature published between 2017 and 2026 on the occurrence of microplastics in African freshwater ecosystems. It examines how local land use, anthropogenic activities, and wastewater treatment plants, as well as the geomorphological characteristics of rivers and lakes and seasonal hydrological dynamics, influence the distribution of microplastics.
