Plastic pollution causes harm to humans, animals and plants through toxic pollutants. It can take hundreds or even thousands of years for plastic to break down so the environmental damage is long-lasting. It affects all organisms in the food chain from tiny species like plankton through to whales.

Safety of Nanoparticles. Current research indicates that exposure via inhalation and skin contact can result in nanoparticles entering the body. Nanoparticles are tiny particles that can be inhaled or ingested and may pose a possible problem both medically and environmentally.

Nanoparticles. Nanoparticles are structures, 1-100 nanometres (nm) in size, that usually contain only a few hundred atoms . This means that nanoparticles are around 100 times larger than atoms and simple molecules . 1 nm is 1 x 10 -9 m (or 0.000,000,001 m).
