Nano Plastics In Our Fish... Oh My…

Nano plastics are seriously harming the ocean! It now appears that plastics account for nearly eighty per cent of all waste found in our oceans.

This plastic gradually breaks down into smaller and smaller particles - until they are microscopic or nano.

New research by Lund University in Sweden, looks into how nanosized plastic particles affect life in the ocean food chain.

Karin Mattsson with the study, "We tested how polystyrene plastic particles of different sizes, charge and surface affect the zooplankton Daphnia. It turned out that the size of the nanoparticles that were most toxic to the Daphnia in our study was 50 nanometers.”

Zooplankton like Daphnia are food for many other aquatic animals and researchers wanted to study the effect of plastic particles higher up in the food chain.

They discovered that fish that ate Daphnia containing nano plastics experienced a change in their predatory behaviour and had a poor appetite.

Researchers have also discovered that the nanoparticles have the ability to cross biological barriers, such as the intestinal wall and brain.

What this study does not go into is - then people eat the fish..oh my…
