Microplastics in marine sediments

Status: Submitted

Definition: Microplastics are fragments of any type of plastic less than 5 mm in length. The data set consists of results of analyzes of the top layer (0-2 cm) bottom sediments in Norwegian sea and coastal areas, which show the amount of microplastic particles in surface sediments. Microplastics are measured in number of particles in 1kg sediment dry weight.

Usage

Microplastics are common in our world today. They cause pollution by entering natural ecosystems from a variety of sources, including cosmetics, clothing, food packaging, and industrial processes. Because plastics degrade slowly (often over hundreds to thousands of years), microplastics have a high probability of ingestion, incorporation into, and accumulation in the bodies and tissues of many organisms. The toxic chemicals that come from both the ocean and runoff can also biomagnify up the food chain. Therefore it is important to map and monitore microplastics in oceans and terrestric ecosystems, to learn about distribution, sources, behavior etc., and to find the ways to reduce the microplastic pollution.
