Density of pelagic microplastics and shoreline macroplastics relative to wave energy and pollution sources. (A) Location of Lake Hovsgol in northern Mongolia. (B)
Density of macroplastic debris in the shoreline surveys (purple, g km1) and microplastic debris in the pelagic surveys (red, particles km2); symbols graduated by density.
Wave energy was modeled using shoreline shape, fetch, bathymetry, and wind direction and speed. Direction of the prevailing winds and location of the wind weather station
are shown. Potential sources for pollution include towns (black circles), tourist camps (black triangles), roads (solid black lines), and rivers (solid blue lines). Dashed line
indicates the park boundary. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
