Researchers found microplastics in 76 of the 77 sites sampled in a new research report that’s being billing as the first statewide survey of plastic waste in Texas waterways.
The study Microplastic in Texas: A survey of the coast and waterways of the Lone Star State, released by Environment Texas Research & Policy Center, included samples collected along the Texas Gulf Coast as well as lakes, rivers and streams, including Leon Creek in San Antonio. The watchdog group compiled existing data from 60 waterways around the state, and its staff and volunteers sampled from 17 additional sites this year.
“The results of our survey are clear: Microplastic is a nearly invisible constant in our waters, from drinking water reservoirs to our favorite swimming holes and fishing spots,” Environment Texas Executive Director Luke Metzger said in a statement. “Texas’ waterways make our state great. They sustain Texans and our diverse wildlife and ecosystems. But the microplastic we found in nearly every waterway we tested can.potentially harm to wildlife and marine life, and may endanger human health.”
Public alarm is growing over the health effects of microplastics, the tiny particles that serve as the building blocks of plastic production but end up as major source of pollution when they’re released during manufacturing and transport.
Scientists estimate that adults ingest the equivalent of one credit card weekly in microplastics, according to Stanford Medicine. Studies suggest exposure to the particles could be linked to cancer, heart attacks, reproductive problems and other serious health risks.
To limit the release of microplastics, Environment Texas’ report recommends industry work harder to prevent spills during the manufacturing process and that government should require producers to take greater responsibility for the waste they produce. Consumers also can help by cutting back on single-use plastics and “fast fashion” items that generate microfibers.
Last fall, Environment Texas banded together with a coalition of fishermen, oyster farmers, tourism groups and medical experts to demand Gov. Greg Abbott and the Texas Commission on Environmental Quality adopt stronger standards requiring plastic manufacturers reduce their discharges into Texas waterways.
“The good news is that this isn’t inevitable,” Metzger added. “We can turn the tide if we address the sources of this pollution, such as plastic pellets and unnecessary single-use plastics.”
