3.6 Conclusions
Rate of degradation of polymeric material in the sea environment is much slower
than it is on land. The main reasons for this may be attributed to the reduced amount
of oxygen solubility in saline water, the type of organisms present, the reduced heat
build-up, changes in conditions as a function of season and so on.
