40. What are the disadvantages of plastic?
Answers
Answer:
Disadvantages of Plastics
Natural decomposition of plastic can last from 400-1000 years and few types of plastics are non-degradable as well. Plastic materials clog waterways, oceans, seas, lakes etc. ... Both creation and recycling of plastic produce toxic gases and residues which causes air and water and land pollution.
Answer:
Plastics production also involved the use of potentially harmful chemicals which are added as stabilizers or colourants. Many of these have not undergone environmental risk assessment and their impact on human health and the environment is currently uncertain.
Such an example is phthalates which are used in the manufacture of PVC. PVC has in the past been used in toys for young children and there have been concerns that phthalates may be released when these toys are sucked. Risk assessment of the effects of phthalates on the environment is currently being carried out. The disposal of plastics products also contributes significantly to their environmental impact.
Most plastics are non-degradable and they may take a long time to break down once they are landfilled. With more and more plastic products, particularly plastics packaging, being disposed of soon after their purchase, the landfill space required by plastics waster is a growing concern.
