what are the problems caused by excessive use of plastics?
These are some of the hazards associated with using plastic:
- Polyethylene, contained in plastic articles including shopping bags, disposable bottles and glasses, chewing gum and toys, is believed to be carcinogenic (cancer causing).
- Some plastic water bottles contain Bisphenol A, a compound that is believed to cause cancer, impair the immune system lead to early puberty and trigger development of obesity and diabetes.
- Polystyrene, the form of plastic used to make styrofoam articles such as disposable cups and plates, it is believed, enters the body with food and accumulates in fat tissues. It can also cause irritation in the eyes, nose and throat.
- Tetrafluoro-ethelyne, the plastic compound used to manufacture non-stick cooking ware, can irritate the eyes and nose and cause respiratory problems
- Acrylic, used in clothes, contact lenses, dentures, adhesives, articles used to prepare food, diapers, sanitary napkins, and other products, can cause vomiting, nausea, diarrhea, respiratory difficulties and headaches.
- Polyvinyl chloride (PVC), a form of plastic used in packaging, containers, utility items and cosmetics has been linked to onset of cancer and birth and genetic conditions. It can also cause bronchitis, skin disease, deafness and vision problems, and digestion and liver related problems.
- Phthalates, present in emulsions, inks, footwear and toys among other products, is associated with hormonal disturbances, developmental issues, cancer, reduced sperm count and infertility and weakened immunity.
The final plastic product is often a chemical entity that in and of itself has had insufficient toxicological and ecotoxicological testing. An example would be PVC, forms of which are banned in Europe but exist widely in children's toys in America. Recent controversies over plastic bottles (many toxicologists recommending not re-using plastic water bottles and not storing food in tupperware) have highlighted the potential risks. Exacerbating the problem is that science is only now advancing to where it can detect plastic components in human blood and then trace concentrations and link them to human ailments and diseases.
The plastics industry itself often spins plastic and related plastic chemicals into a variety of products, some of which are hazardous and controversial (Teflon, PVC, Polyethylene, polystyrene, various silicones in body and hair care). Plastic-producing companies are often chemical companies or subsidiaries of chemical companies, both with poor track records when it comes to their adherence to regulatory compliance and their willingness to perform toxicological analysis on the products they make.
Plastics often leech component chemicals, including hazardous chemicals, through common temperature changes. It is for this reason that toxicologists do not recommend storing very cold foods in plastics or heating foods (microwaving especially) in plastics.
Plastics are durable materials. Thus, they are hard to eliminate once used and create tremendous waste. While some common plastics can be recycled (plastics used in common soda and milk bottles), the vast majority cannot. They take up a lot of space in landfills and create air pollution when incinerated.
Disadvantages of plastics:
Plastic is a nonrenewable resources.
Plastic is softness.
Disadvantage of plastics are embrittlement at low temperature.
Disadvantage of plastics are deformation under load.
Disadvantage of plastics are low heat resistant and poor ductility.
Disadvantage of plastics are combustibility.
Avoid plastic is very helpful to us because it destroys soil.
It is a recycle process, but it is very costly.
