Pellets or nurdles as they are often called, are pre production plastic resin pellets.Essentially raw plastic before it has been made into an end use item such as a plastic bag, bottle or toy. They can cause harm in several ways.If they are ingested by fish and marine life they can block digestive systems leading to starvation (see definition for ingestion). It is known that common chemicals (POPs and PCBs) that accumulate on the pellets can be highly toxic with concentrations on the pellets up to a million times the level of the surrounding seawater. Pellets can also have chemicals added to them during the manufacturing process, chemicals such as Nonylphenol (NP) is used as an antioxidant and plasticizer in some plastic products and has known endocrine-disrupting potential.Thesepellets are ubiquitous on beaches worldwide and commonlyfoundthroughout the world’s oceans. Plastic end up in the environment as they are transported from the manufacturing plant to factories via trucks, trains and cargo containers on ships and spills can occur during manufacture as well as throughout transportation.As pellets are extremely lightweight and float in water they can easily end up in drains, rivers and the sea.
