Solution: c)

Nurdles are tiny plastic pellets, the size of lentils. They are ‘pre-production plastic pellets’ that are the raw material for most of today’s plastic products. Made out of polyethylene, polypropylene, polystyrene, polyvinyl chloride and other plastics, these pellets are melted down and cast into the moulds to make various plastic products.

They are the main form in which plastic is shipped all over the world after being made in processing factories and then carried to manufacturing factories.

Depending on their density, nurdles can either float to the surface of the water or sink below the surface.

Nurdles, if left exposed to the environment, will slowly break down into microplastics. Since nurdles are plastic, they are not biodegradable.

Nurdles are the second-largest source of micropollutants in the oceans by weight.

The International Maritime Organization (IMO) has not deemed nurdles hazardous enough to be regulated by the organisation’s dangerous goods code for safe handling and storage.
