Microplastic Detection Data from Gahai Lake, Gansu Province

International Journal of Environmental Research 2026
wu guo hong

Summary

Surface water samples collected from Gahai Lake in Gansu Province, China, across three seasons in 2025 documented microplastic abundance, particle size distributions, and dimensions in a high-altitude lake ecosystem. This dataset provides baseline contamination data for a relatively pristine inland water body, supporting broader assessments of microplastic dispersal into remote and protected environments.

In 2025, we collected and analyzed samples from the surface water (0–20 cm depth) of Gahai Lake in April, July, and October to determine the abundance, particle size, and dimensions of microplastics, resulting in this dataset.
