ABSTRACT
Microplastics (<5â¯mm) are ubiquitous in the marine environment, occurring in both sediments and surface waters worldwide. However, few studies have documented the presence of microplastics and tire wear particles in coastal rivers. A survey of microplastics and low-density tire wear particles (≥63⯵m) in the sediment and surface water of the three major tributaries within the Charleston Harbor estuary was conducted. Intertidal sediment, subtidal sediment, and sea surface microlayer concentrations ranged from 0 to 652â¯microplastics/m2, 3-4,375 microplastics/kg wet weight, and 3-36â¯microplastics/L, respectively. Blue fibers and tire wear particles were the two most abundant microplastic types observed, constituting 26.2% and 17.1%, respectively, of total microplastics. Tire wear particles were primarily identified by morphology, and ATR-FTIR analysis was conducted for a small subset (nâ¯=â¯5) of larger particles (≥500⯵m). The present study provides the first microplastic field assessment of low-density tire wear particles in estuarine tributaries.
