There can be 240,000 plastic particles in a litre bottle of water

A single 1-litre bottle of water could contain 240,000 microscopic plastic particles. The health implications of ingesting plastic are unclear, but early research suggests such particles could travel into various organs within the body.
Millions of tonnes of plastic are produced every year as a result of human activity, such as the fishing industry and domestic waste. Most of this is made up of microplastics, which measure between 1 micrometre and 5 millimetres across.
