Influence of Drainage Infrastructure and Land Use on Microplastic Contamination in Urban Watersheds in Michigan in 2019

Data that compares microplastic (MP) morphologies and abundances upstream and downstream of 20 stormwater outfalls to determine the influence of outfall type on MP accumulation. Three surface water and sediment samples were collected at each sampling location, along with measurements of chemical and physical water quality parameters. Microplastics were identified using Nile Red staining, a rapid and effective screening technique suitable for large-scale environmental assessments while minimizing resource-intensive analyses.<br>
