Question

Plastic and its hazart to are envorment and our contribution to nature

Answer 1

Answers:-

The problem created by the use of plastics bags is primarily due to shortcomings in the waste management system. Indiscriminate chemical additives pose environmental problems including choking open drains, ground water contamination, etc.

What are Plastics?

Plastics are polymers i.e. large molecules consisting of repeating units called monomers. In the case of plastic bags, the repeating units are ethylene. When ethylene molecules are polymerized to form polyethylene, they form long chains of carbon atoms in which each carbon is also bonded to two hydrogen atoms.

Explanation:

Plastics are not intrinsically toxic or harmful. But plastic carry bags are manufactured using organic and inorganic additives like colorants and pigments, plasticizes, antioxidants, stabilizers and metals. Plasticizes are organic esters of low volatile nature. They can migrate to food stuffs as a result of leaching. Plasticizes are also carcinogenic.

Antioxidants and Stabilizers are inorganic and organic chemicals to protect against thermal decomposition during manufacturing process.Plastic bags if not disposed properly may find their way into the drainage system resulting into choking of drains, creating unhygienic environment and causing water borne diseases. Recycled /colored plastic bags may contain certain chemicals, which can leach to the ground and contaminate soil and sub-soil water. Units not equipped with environmentally sound techniques for recycling may create environmental problems due to toxic fumes generated during reprocessing
