When PBTs encounter plastic debris, they tend to preferentially sorb (take up or hold) to the debris. It is estimated that approximately 90% of the plastics in the pelagic marine environment are microplastics (less than 5 mm in diameter) (Eriksen et al., 2013; Browne et al., 2010; Thompson et al., 2004). It is estimated that up to 12 million metric tons of plastic enter our ocean each year.. Our oceans are slowly turning into a plastic soup, and the effects on ocean life are chilling. Last updated: July 28, 2020. There is a growing concern about the hazards plastic pollution in the marine environment. How Plastic In The Ocean Is Contaminating Your Seafood : The Salt Fish can absorb toxic chemicals that have been dumped into waterways, but they can also get them from eating plastic… Everest, to the Mariana Trench, the deep point in our oceans. Millions of tons of plastic enter the oceans every year, polluting our seas, littering our beaches and endangering wildlife. These micro- and nanoparticle plastics, as well as other microplastics caused by fragmentation, are available for ingestion by a wide range of animals in the aquatic food web. The problem of plastic in nature, particularly in our oceans, is a global crisis. Stemming the plastic tide. The flow of plastics into our environment has reached crisis proportions, and the evidence is most clearly on display in our oceans. The physical breakdown of plastics is likely to decrease in the deep sea and non-surface polar environments, where weathering is less of a factor. The longer plastic is in the water, the more weathered and fragmented it becomes (Teuten et al., 2007). (Eriksen et al., 2013). Press releases United States Environmental Protection Agency, The Subset of Plastic Trash known as Microplastics, Persistent Bioaccumulative and Toxic Substances (PBTs) And Plastics. There is a growing concern about the hazards plastic pollution in the marine environment. Aug. 2012 petition to regulate plastics as a pollutant under the Clean Water Act, Dec. 2012 petition to designate Northern Hawaiian Islands as a Superfund site, Media photos With skyrocketing plastic production, low levels of recycling, and poor waste management, between 4 and 12 million metric tons of plastic enter the ocean each year—enough to cover every foot of coastline on the planet!And that amount is projected to triple in the next 20 years. We need urgent action to address the global plastic pollution epidemic. Every day approximately 8 million pieces of plastic pollution find their way into our oceans. At current rates plastic is expected to outweigh all the fish in the sea by 2050. Global trends suggest that accumulations are increasing in aquatic habitats, consistent with trends in plastic production. The pathway by which plastics enters the world's oceans. Floating on the ocean surface, the plastic litter may get caught in one of the many wind-driven ocean currents and then make its way to the center of an ocean gyre—a massive circling ocean current. Persistent, bioaccumulative and toxic (PBTs) chemicals or substances pose a risk to the marine environment because they resist degradation, persisting for years or even decades. Sign our petition to protect marine wildlife from deadly plastic pollution. Although nearly every type of commercial plastic is present in aquatic/marine debris, the floating components are dominated by polyethylene and polypropylene because of their high production volumes, their broad utility, and their buoyancy. To achieve this objective, we have to work on a combination of closing the source and cleaning up what has already accumulated in the ocean and doesn’t go away by itself. According to the National Ocean Service, the vast majority of ocean pollution — a whopping 80 percent — comes from the land.It’s often caused by something called nonpoint source pollution, which occurs when the rain or melting snow picks up … Recent information on the use of tiny plastic abrasives (commonly called microbeads or nanobeads), especially in personal care products and home cleaning products, and synthetic fabrics shedding during laundering has shown the prevalence of micro- and nanoparticle size plastics as being pervasive in some water bodies. Unfortunately, plastic is so durable that the EPA reports “every bit of plastic ever made still exists.” All five of the Earth's major ocean gyres are inundated with plastic pollution. After some amount of time in the ocean, floating plastic debris may become sufficiently fouled with biological growth that the density becomes greater than seawater, and it sinks (Ye, Andrady, 1991). The problem is growing into a crisis. Plastic pollution is one of the greatest threats to ocean health worldwide. A study published in 2017 estimated between 1.15 to 2.41 million tonnes of plastic enters the oceans via rivers annually, with peak months being between May and October. Buoyancy is dependent on the density of the material and the presence of entrapped air (Andrady, 2011). Thousands of seabirds and sea turtles, seals and other marine mammals are killed each year after ingesting plastic or getting entangled in it. Although nearly every type of commercial plastic is present in marine debris, floating marine debris is dominated by polyethylene and polypropylene because of their high production volumes, their broad utility, and their buoyancy (Colton et al., 1974; Ng and Obbard, 2006; Rios et al., 2007). Retrieved from: lastbeachcleanup.org/countrylaws A comprehensive list of global laws relating to plastic products. The Great Pacific Garbage Patch is a gyre of plastic debris in the north-central Pacific Ocean. We are dedicated to ending plastic pollution and fostering sustainable communities worldwide. It’s the largest accumulation of plastic in the world. The following 10 facts shed light on how plastic is proving dangerous […] Different pollutants sorb to different types of plastics in varying concentrations depending on the concentration of the PBT in seawater and the amount of plastic particle surface area available. With increased fragmentation comes higher relative surface area, thereby increasing the relative concentration of sorbed PBTs (a process referred to as hyperconcentration of contaminants) (Engler, 2012). • Coral Conservation. Plastics on the seafloor may sorb PBTs from the sediments (Graham, Thompson, 2009; Rios et al., 2007), in addition to sorbing them from the seawater. Plastic accumulating in our oceans and on our beaches has become a global crisis. Some of the plastic in the ocean originates from ships that lose cargo at sea. Microplastics arise from the fragmentation of larger pieces as they weather from the effects of ultraviolet rays, and wind and wave action.

Plastic pollution is most visible in developing Asian and African nations, where garbage collection systems are often inefficient or nonexistent. Plastic Oceans International is a US-based 501 (c)(3) non-profit organization whose goal is to end plastic pollution and to foster sustainable communities worldwide.
