Zusammenfassung:This study address for the first time in Argentina and the South American continent the effect of water management on the presence of microplastics (MPs) in a shallow lake, assessing their contribution to the zooplankton fraction. Water samples were collected in the lake and its principal affluent, an irrigation channel, from winter 2018 to summer 2019 with a zooplankton net (47 μm). MPs were present in all analyzed samples, with a dominance of fibers, black color, and ≤ 1000 μm range size. MPs concentration was maximum during summer at the lake (180 MPs m −3 ) while during spring (140 MPs m −3 ) at the channel. Rotifers and cyclopoids dominated the zooplanktonic fraction at both sites which range sizes (
