Microplastic in the food chain
A microplastic particle becomes highly toxic when it absorbs harmful substances and passes them on to other marine organisms through the food chain.
Phytoplankton – Single-celled plants, which live in the upper water layer and perform photosynthesis with the help of sunlight
Zooplankton – Animal Microorganisms, who subsist on phytoplankton. Surrounded by microplastic particles in similar sizes
Microplastic – Plastic particles up to 5 mm big, who break apart in the ocean water over the years and draw in and accumulate persistent organic pollutants (POPs)
Herring – Subsists on little fish and zooplankton including microplastic, chemical substances like POPs can get into the organism’s digestion system
Tuna fish – Subsists on little fish like Herring. The consistant intake of POPs sums up to a big amount.
Humans – Subsists on fish and mussels. Europeans intake up to 11,000 microplastic particles per year with a mean consumption of fish. The percentage that stays in the human body is still unknown
