Microplastics is common name for plastic parts, less than 5mm in size, which are
formed either through fragmentation of macroplastics, or are specifically created and used in
various industries. In the last 40 years, microplastics have been actively accumulating and
polluting the marine environment, in particular, causing damage to marine organisms.
This paper presents microplastics, its physical and chemical characteristics, its origin,
and the consequences it has on the marine ecosystem. A special emphasis is placed on the
negative effects of microplastic intake for marine organisms.
