Chapter 1: The Hidden Threat of Microplastics

Microplastic particles and beads, observed through a microscope, have been collected from 11 national parks and wilderness areas in the western United States over a 14-month period.

Researchers are astounded by the sheer quantity of minuscule plastic particles that are descending from the atmosphere, resembling dust and rainfall. This phenomenon, often referred to as "plastic rain," highlights a troubling trend in even the most remote environments.

A saying I heard in my youth captures the essence of human littering: “No matter where you venture, a beer can will arrive first.” Now, we must include airborne plastic particles in that observation.

These plastic fragments, which drifted through the air and settled in precipitation, were identified in soil samples taken from various secluded locations. Scientists estimate that over 1,000 tons of microplastics, all human-made materials that do not naturally occur, are deposited annually on these protected lands—equivalent to approximately 123 million plastic water bottles.

This estimation pertains only to the wilderness and parks examined, representing a small fraction of the total landmass in the U.S. There is little doubt that plastic is falling in other regions nationwide and globally.

As stated in the June 12 issue of the journal Science, “No place is safe from plastic pollution.”

“I suspect that urban areas might experience even higher deposition rates,” suggests study leader Janice Brahney, PhD, an assistant professor of watershed sciences at Utah State University. “However, our understanding of where these rates might peak remains limited.”

While the discovery might not be shocking, the magnitude of the “plastic rain” is indeed staggering.

“We were taken aback by our findings regarding deposition rates and repeatedly checked our calculations,” Brahney reported. “Through 32 different particle scans, we confirmed that about 4% of the atmospheric particles analyzed from these remote sites were synthetic polymers.”

Microplastics, comparable in size to dust particles, have been detected in both water and land globally. However, their origins and distribution remain largely unknown. Current assumptions suggest that these tiny plastic pieces circulate worldwide, much like water and natural dust. Essentially, plastic is pervasive.

“Our findings indicate that the plastic cycle mirrors the global water cycle, encompassing atmospheric, oceanic, and terrestrial phases,” Brahney elaborated. “Microplastics, being less dense than soil, may travel farther than natural dust particles,” other researchers noted in a related commentary in the journal.

The predominant forms of plastic found were microfibers from clothing and industrial materials, with about 30% being vibrant microbeads believed to originate from industrial paints and coatings.

Even smaller plastic particles, too small for the research team's microscopes, are likely also present. Brahney mentioned via email that some of the smallest plastic fragments are known to enter human lungs.

Other studies have indicated that we are continually inhaling and ingesting microplastics that were nonexistent a century ago, prior to the widespread production of plastic. Additionally, there is growing concern that microplastics can adversely affect aquatic life, thereby disrupting entire food chains. Recent research in the journal Global Change Biology suggests that plants are also at risk from microplastic exposure.

“There is some indication that plastics may influence soil temperatures and moisture retention,” Brahney conveyed in an email. “This raises numerous questions about the long-term effects of plastic accumulation in vulnerable ecosystems.”
