•Sampling with Niskin bottles and microfiltration in Lakes Superior, Michigan and Huron revealed the presence of microfibers.•Microfibers may be under-represented in estimates of plastic pollution if microfiltration is not included in sampling.•Aquatic studies that target nanoplastics similar in size to the prey items of zooplankton should incorporate filtration.
Microfibers were identified in filtered water from Lake Superior, Lake Michigan and northern Lake Huron in the United States. Sampling with a Niskin bottle followed by microfiltration (0.45 μm filter), a sampling methodology rarely used in microplastics sampling, revealed an average microfiber concentration of 0.119 +/- 0.04 microfibers/mL. Microfibers may be under-represented in estimates of micro- and nanoplastic pollution if microfiltering is not included in the sampling scheme.
