Microplastics are fragments of plastic smaller than 5 millimetres across that pollute water sources across the world. Their possible health effects are a cause of concern, although we still know little about their impact in the body. They can be removed from water supplies by using a fossil fuel-based gel, polyacrylamide, but this can be toxic to humans under certain conditions.

Now, …
