NSF Grants Fund Microplastic Research at Universities

published on 29 April 2024

The National Science Foundation (NSF) is funding innovative research projects at universities across the U.S. to study microplastic pollution - tiny plastic particles that harm ecosystems and human health. Key projects receiving grants:

University Project Description Grant Amount
North Carolina State University Developing technology to remove microplastics from water using microcleaners and engineered microorganisms $2 million
Oregon State University Studying impacts of micro- and nanoplastics on aquatic life $3.3 million

Microplastics enter the environment from larger plastic debris breaking down, microbeads in personal care products, and manufacturing resin pellets. They've been found in marine life, seafood, and drinking water, causing physical harm and transferring contaminants up the food chain.

Universities are using diverse methods to detect microplastics, like AI algorithms and plasmonic materials, and explore removal techniques like self-propelled microcleaners and engineered microorganisms. Future research priorities include developing better detection methods, studying human health impacts, exploring removal solutions, and understanding food chain effects.

Continued funding and collaboration are crucial to address this global environmental issue effectively.

What are Microplastics?

Microplastics are small plastic pieces that are less than 5 millimeters in size. They can come from various sources, including:

  • Larger plastic debris that breaks down into smaller pieces
  • Microbeads found in personal care products
  • Resin pellets used in manufacturing processes

These tiny plastic particles can easily pass through water filtration systems and enter the environment, causing harm to ecosystems and human health.

Sources of Microplastic Pollution

Microplastics can enter the environment through various pathways, including:

Source Description
Larger plastic debris Breaks down into smaller pieces over time
Microbeads Found in personal care products like face wash, toothpaste, and cosmetics
Resin pellets Used in manufacturing processes

Impact on Ecosystems and Health

Microplastics have been found in:

  • Marine organisms
  • Commercial seafood
  • Drinking water

When ingested, microplastics can cause:

  • Physical harm
  • Block digestive tracts
  • Leach toxic chemicals into the body

Furthermore, microplastics can facilitate the transfer of contaminants along the food chain, potentially harming human health. The persistence and widespread presence of microplastics in the environment make them a pressing concern that requires immediate attention and action.
