A new study from Texas suggests that microplastics are no longer a problem limited to distant oceans or abstract environmental debates.
Instead, researchers found plastic pollution in nearly every North Texas waterway they surveyed, raising new concerns about what's getting into places where people fish, boat and swim, KERA News reports.
What's happening?
Environment Texas, a Dallas-based research and policy center, analyzed 77 waterways in North Texas and found microplastics throughout the region.
These locations included popular waterways and recreation areas such as the Trinity River, White Rock Lake, and Mountain Creek Lake.
Speaking at a press conference on July 23, Environment Texas City Hall spokesman Ian Seamans said the findings indicate widespread contamination.
«"Our report today finds that microplastics have become a virtually invisible, permanent fixture of Texas water supplies," Seamans said.
Microplastics are tiny plastic fragments less than 5 millimeters in size. Most microplastics are formed when larger plastic items break down over time, but some microplastics are formed from products made from small plastic particles.
According to Seamans, "the vast majority of the objects found contained plastic fibers," and plastic pellets, the raw material used to make many plastic products, were also found in several places.
Why is this important?
These Texas waterways support recreation, local ecosystems, and industries related to fishing and tourism.
If microplastics are so widespread, then exposure could be widespread in places that many residents consider normal, familiar, and safe.
The report warned that microplastics pose a risk to both wildlife and humans, highlighting the immediate threat to fish and waterfowl.
«"This poses a serious physical hazard," the report notes. "These plastics can cause choking and intestinal blockages, and animals that ingest too much plastic can starve to death.".
The findings also raise concerns about the food chain and habitat, and add to growing concerns about pollution of recreational waters and wildlife habitats.
Former North Texas State Assemblyman Jason Villalba said the economic impact could be significant.
«"The fishing and tourism industries are suffering greatly from the impact of microplastics," he said, warning that without government intervention, the problem could get even worse for these sectors.
What is being done?
The group is calling on Governor Greg Abbott and state environmental officials to take action to tighten controls on plastic waste, especially plastic pellets.
Calling pellets "one of the most preventable sources of microplastics," Seamans said, "TCEQ must take immediate action to completely eliminate the discharge of pellets into Texas waterways.".
Seamans said more than 100 doctors, fishermen, fishermen and tourism industry representatives along the Gulf Coast have joined the initiative to take action.
Villalba said bills aimed at better regulating microplastics have already been introduced in recent legislative sessions, and suggested the issue could resurface with greater force.
The study suggests that the biggest improvements will likely come from stricter industry standards, better waste management, and enforcement of policies to prevent plastic pollution from entering waterways before it officially occurs.
«"We're seeing a real surge heading into the 2027 legislative session," Villalba added.
