AI Article Synopsis
- Microplastics are becoming a significant concern in urban freshwater areas, yet there is limited research on them, especially in densely populated regions.
- A study of eight urban lakes in Changsha, China, revealed microplastic concentrations ranging from approximately 2425 to 7050 items per cubic meter, with the highest levels in Yuejin Lake.
- The study found that most microplastics were linear, transparent, and less than 2 mm in size, with polypropylene being the most common type, indicating the influence of human activity on their presence in these urban lakes.
Article Abstract
As emerging pollutants, microplastics have attracted the attention of scholars from all over the world. However, there is a lack of research on freshwater areas, even in densely populated urban areas. This study investigated eight urban lakes in Changsha, China. It was found that microplastic concentrations ranged from 2425 ± 247.5 items/m to 7050 ± 1060.66 items/m in the surface water of research areas and the maximum concentration was found in Yuejin Lake, a tourist spot in the center of the city. Anthropogenic factors are an important reason for microplastic abundance in urban lakes. The major shape of microplastics was linear and most of the microplastics were transparent. More than 89.5% of the microplastics had a size of less than 2 mm. Polypropylene was the dominant type in the studied waters. This study can provide a valuable reference for a better understanding of microplastic pollution in urban areas of China.
