Analysis of information sources in references of the Wikipedia article "Microplastics" in English language version.
First, it is necessary to define what constitutes a 'nanoplastic'. Nonoparticles exhibit specific properties that differ from their bulk counterparts and are generally considered as particles with less than 100nm in at least one dimension. [...] However, for nanoplastics, a clear consensus classification has not been reached and multiple size-based definitions have been proposed. [...] although nanoplastics are the least known type of plastic waste, they are also, potentially, the most hazardous. [...] Nanoplastics may occur in the environment as a result of their direct release or from the fragmentation of larger particles. They may, similarly to microplastics, [...] therefore be classified as either primary or secondary nanoplastics.
In the USA, for instance, the Marine Plastics Pollution Research and Control Act of 1987 not only adopted Annex V, but also extended its application to US Navy vessels

The U.S. Navy is taking a proactive approach to comply with the prohibition on the at-sea discharge of plastics mandated by the Marine Plastic Pollution Research and Control Act of 1987
China was responsible for the most ocean plastic pollution per year with an estimated 2.4 million tons, about 30 percent of the global total, followed by Indonesia, the Philippines, Vietnam, Sri Lanka, Thailand, Egypt, Malaysia, Nigeria and Bangladesh.
