11.8.5—Environmental challenges caused by question 1
[Maximum number: 2]
There are two types of polymerisation, addition and condensation.
Some plastics, formed by polymerisation, are non-biodegradable.
Describe two pollution problems that are caused by non-biodegradable plastics.
Any two from:
ingestion can be fatal to animals / owtte;
animals can be caught in plastics e.g. fishing line / owtte;
combustion releases toxins / owtte;
land-fill uses natural resources / owtte;
allow: any appropriate example
