Volunteers and researchers are working to combat the growing threat of microplastics in Galveston Bay, with alarming findings indicating high levels of contamination affecting marine life and potentially human health.
GALVESTON- The news group ABC13 participated in a plastic cleanup event at Sylvan Beach earlier this month, where volunteers convened to confront the concerning prevalence of microplastics along the shore.
Following the event, ABC13 interviewed researchers from the University of Houston Clear Lake to obtain a better understanding of the extent of plastic contamination in Galveston Bay.
Dr. Jenny Oakley, the associate director of research programs at the Environmental Institute of Houston, has been overseeing a team that has collected and analyzed water and soil samples from Galveston Bay over the past three years.
Their primary objective has been to identify microplastics, which are plastic particulates less than 5 millimeters in diameter. Although nurdles, which are larger plastic pellets, are a well-known form of microplastic, the majority of microplastics are microscopic fragments and filaments that result from plastic degradation.
Dr. Oakley's team's initial findings are concerning, as they are the first to quantify the quantity of microplastics in Galveston Bay. She stated that the concentrations we observed during our sampling events were higher than those reported by other groups along the Gulf Coast.
The pervasive nature of contamination is indicated by the presence of at least one form of microplastic in each sample collected.
In addition to physical plastic debris, Diane Wilson, a former shrimp farmer and advocate for clean waterways, emphasized the issue of chemical pollution. She observed a white powder drifting on the surface of the water at Sylvan Beach, which was a residue of plastic pollution. Wilson cautioned that plastic pollution infiltrates every region of Galveston Bay and ultimately affects its marine life.
Dr. Oakley provided further insight into the potential consequences of microplastics for marine organisms, stating, "When a critter interacts with those microplastics, they are exposed to the physical plastic in their digestive tract as well as to various toxins associated with those microplastics." This exposure raises concerns regarding the potential health risks to both marine life and humans who ingest seafood.
In July, the Environmental Protection Agency (EPA) disclosed new initiatives to examine the effects of microplastics on human health.
Previous studies have identified microplastics in seafood, such as oysters and fish, which has prompted concerns regarding the potential for human consumption of these contaminants.
The global community is concerned about the prevalence of microplastics in various environments, such as the oceans, air, and food.
Recent research has detected microplastics in human tissues, such as the heart and lungs. This has raised concerns regarding their potential long-term health complications.
Community initiatives, such as the cleanup at Sylvan Beach, are essential in addressing the pervasive issue of plastic contamination, which is becoming increasingly recognized.
Researchers and activists underscore the necessity of continuous monitoring and action to safeguard the environment and public health from the hazards of microplastics.
