GW Expert Available: UN Committee Meets This Week on Treaty to End Global Plastic Pollution

Talks are underway this week to create a global treaty that would bring an end to plastic pollution. According to The Associated Press, a United Nations committee is meeting in Paris to work on what would be a landmark agreement that…

Perfect ‘Pathogen’ Storm: Vibrio Bacteria, Sargassum and Plastic Marine Debris

Little is known about the ecological relationship of Vibrio bacteria with Sargassum. Evidence also is sparse as to whether vibrios colonizing plastic marine debris and Sargassum could potentially infect humans. As summer kicks off and efforts are underway to find solutions to repurpose Sargassum, could these substrates pose a triple threat to public health? Results of a study representing the first Vibrio spp. genome assembled from plastic finds Vibrio pathogens have the unique ability to “stick” to microplastics, harboring potent opportunistic pathogens.

Chemicals could undercut global plastics treaty

Next week the UN intergovernmental negotiating committee (INC) on plastic pollution will meet in Uruguay to develop an international legally binding instrument against plastic pollution. There is concern among scientists that the negotiations will overlook the diversity and complexity of chemicals present in plastics. This would severely undermine the treaty’s effectiveness, according to a new study published in the recent issue of the scientific journal Environmental Science & Technology Letters.

Blind spots in the monitoring of plastic waste

Whether in drinking water, food or even in the air: plastic is a global problem – and the full extent of this pollution may go beyond of what we know yet. Researchers at the Karlsruhe Institute of Technology (KIT), together with partners from the Netherlands and Australia, have reviewed conventional assumptions for the transport of plastic in rivers.

A Sea Change for Plastic Pollution: New Material Biodegrades in Ocean Water

Seeking solutions to counteract a rapid rise in plastic trash, scientists at UC San Diego have developed biodegradable material that is designed to replace conventionally used plastic. In a new study, an interdisciplinary team of researchers has shown that the material biodegrades in seawater.

Polystyrene waste is everywhere; scientists just found a way to break it down

Scientists at the U.S. Department of Energy’s Ames Laboratory and their partners from Clemson University have discovered a green, low-energy process to break down polystyrene, a type of plastic that is widely used in foam packaging materials, disposable food containers, cutlery, and many other applications.

Microplastic Sizes in Hudson-Raritan Estuary and Coastal Ocean Revealed

Rutgers scientists for the first time have pinpointed the sizes of microplastics from a highly urbanized estuarine and coastal system with numerous sources of fresh water, including the Hudson River and Raritan River. Their study of tiny pieces of plastic in the Hudson-Raritan Estuary in New Jersey and New York indicates that stormwater could be an important source of the plastic pollution that plagues oceans, bays, rivers and other waters and threatens aquatic and other life.

Plastics pose threat to human health

Plastics contain and leach hazardous chemicals, including endocrine-disrupting chemicals (EDCs) that threaten human health. An authoritative new report, Plastics, EDCs, & Health, from the Endocrine Society and the IPEN (International Pollutants Elimination Network), presents a summary of international research on the health impacts of EDCs and describes the alarming health effects of widespread contamination from EDCs in plastics.

Pervasive plastics increase exposure to harmful chemicals

The Endocrine Society and IPEN will release a comprehensive joint report Dec. 15 on endocrine-disrupting chemicals in plastics and the threat they pose to public health. Experts will share highlights from the report during a virtual news conference Dec. 15.
