Abstract

Microplastics are beads, fibers, fragments, and sheets smaller than 5 mm. Though tiny, microplastics, over the last several years, have been shown to be toxic to humans and other organisms (Wang, Zhao, and Xing 2021). Many coastal marine organisms, such as intertidal snails, manatees, and sea turtles, have been studied to find that they ingest microplastics. (Curl et al. 2023; Kleinschmidt and Janosik 2021; Gowans and Siuda 2023). Seagrass, another organism closely connected to the community of shoreline marine life, has also been studied to contain microplastics attached to epiphytes growing on seagrasses (Huang Yuzhou 2020; Seng et al. 2020). This study quantified and characterized microplastics embedded in Turtle and Shoal grasses. Water samples were also taken above the turtle and shoal grass to compare microplastic quantity and characteristics. Samples were taken from seagrass beds at Seaglades, Pensacola, FL, Woodlawn Beach, FL, and Navarre Beach Sound, Navarre, FL.
