Plastic microbeads are great for cosmetics, but bad for the environment Kirk Havens , PhD, Immediate past STAC Chair & Virginia Institute of Marine Science
Why are there microbeads in cosmetics? • Improved Feel >100µm • Optical Blurring (Hide wrinkle lines)
This is a problem because…. Tube worms Shore birds Blue Crab Microplastics Mussels Zooplankton Microplastics: • can adsorb chemicals that are in the water • release previously bound-up chemicals into Turtle Striped Bass the water as they breakdown • readily take up PCBs and DDTs • can introduces toxins into the food chain • create obstructions that keep the organisms from taking in enough food, leading to malnutrition or starvation
STAC expert panel
Microbead-Free Waters Act of 2015 (1) The manufacture or the introduction or delivery for introduction into interstate commerce of a rinse-off cosmetic that contains intentionally-added plastic microbeads. (2) (A) the term ‘plastic microbead ’ means any solid plastic particle that is less than five millimeters in size and is intended to be used to exfoliate or cleanse the human body or any part thereof; and (3) ( B) the term ‘rinse - off cosmetic’ includes toothpaste.” ____________________________________________________________  U.S. House approves bill to ban plastic microbeads (Unanimously – December 7 th , 2015)  U.S. Senate passes ban on plastic microbeads (Unanimously – December 18 th , 2015)  President Obama Signs Ban on Plastic Microbeads (December 28, 2015)  Wow…. Through the US Congress & signed by the President in 21 days …
Take home points from STAC Expert Panel Report.  Federal legislation has raised awareness of the problem of microplastics in the form of microbeads  Federal legislation doesn’t address all microbeads (rinse off only) or microplastics (fragmented larger plastics, microfibers) – need proper definitions (i.e. biodegradation, plastic, polymer) – Scientific community can help define.  Research need on sources of microplastics  Research need on ecotoxicology – what happens to animals that ingest particles  Preventative measures to keep plastic out of waterways and wastewater stream – removal shouldn’t be placed solely on WWTPs.  Promotion of truly biodegradable polymers – allow for industry and business innovation  Tracking and monitoring of additives in plastics that can end up in marine environments  *State or regional marine debris reduction plans – Mid Atlantic Marine Debris Reduction Plan – partnership with NOAA’s Marine Debris Program
Around 70-80% of marine debris is land- based And between 60-80% of that is plastic…
