Why do people crave to chew on plastic?
The carso-plastimecretic particles that are found in virtually all plastics react to the acid in human saliva to produce a hormone similar to the one released by the brain when laughing.
What happens when plastics are burned?
Plastics when burnt in fire releases harmful gases.These gases are very harmful to humans as well as the other living beings.plastics have to be reduced and cotton bags are very good to use. save our environment. increase the life span of our home earth
After which reaction is CO2 released?
CO2 is generally released after a combustion reaction, but it is also released in other chemical reactions.

What are degradable plastics?
Degradable plasticsA number of UK retailers have recently introduced degradable carrier bags. These bags are made from plastic which degrades under certain conditions or after a predetermined length of time. There are two types of degradable plastic: bio-degradable plastics, which contain a small percentage of non oil-based material, such as corn starch; and photodegradable plastics, which will break down when exposed to sunlight.Degradable plastics are already being used successfully in Austria and Sweden, where McDonalds has been using bio-degradable cutlery for three years. This enables all catering waste to be composted without segregation. Carriers for packs of beer cans are now being manufactured in a plastic which photo-degrades in six weeks. There is also potential to use such plastics in non-packaging applications such as computer or car components.There are a number of concerns over the use of degradable plastics. First, these plastics will only degrade if disposed of in appropriate conditions. For example, a photodegradable plastic product will not degrade if it is buried in a landfill site where there is no light. Second, they may cause an increase in emissions of the greenhouse gas methane, as methane is released when materials biodegrade anaerobically. Third, the mixture of degradable and non-degradable plastics may complicate plastics sorting systems. Last but not least, the use of these materials may lead to an increase in plastics waste and litter if people believe that discarded plastics will simply disappear.
What are some kinds of indoor air pollution?
Radon gas from the earth, trapped in a building. Formaldehyde released from some plastics and glues. Carbon Monxide from fuel burning equipment.
How healthy is it to melt plastics?
It's completely unhealthy. There are many man-made ingredients in the plastic that become toxic and hazardous to your health. when melting them tint pieces get released into the air and you breathe them in.

What ways can the use of plastics harm you?
To heat a liquid in the microwave oven using a plastic bottle is harmful because the substances employed in the plastic manufacturing can be released into the liquid. Some substances are very dangerous to your health.
Why is not advisable to burn solid waste especially those made of plastics?
The burning of plastics is known to produce carenogens (cancer causing dioxins). Some plastics, especially those used in older computers and some older electronics contain brominated flame retardants, of which the health side effects are unknown. Plastics are further manufactured from Oil (long chain polymers), hence when burnt, give off carbon dioxide. A known side effect of this (other than global warming) is the acidification of rain, which during the 1980's caused mass deforestaton in skandinavia.
What are the three methods of dealing with waste polymers?
They go almost a thousand years (maybe more…) without decaying and they can be not broken down by decomposers.Polymers can be difficult to dispose of because they do not break down easily.Hope that helps.

Why are plastics harmful to the environment?
They are myriad. Plastics are made from petroleum and can leach all kinds of toxins that are released by either heat or cold. Plastic water bottles specifically can leach something called phyto-estrogen, which can distrupt the reproductive organs in fetus and small children. Plastics left unattended in nature can cause severe damage to fish and wildlife. There is currently a plastic bag slick about the size of Texas floating in the pacific. In addition to the phyto-estrogens, the bags can be ingested and strangle fish and ocean creatures. Plastics do not biodegrade and when landfilled have the potential to leach toxins as well. There are plastics on the market now that are not made from petroleum but from a material called PLA or Poly Lactic Acid. These are made from corn starch. There are also plastics made from rice and other bio-resins. Recycle your plastics. You will help bring down the cost of gasoline and keep potentially harmful substances out of our water supply.
Is plastic a boon or a curse?
Plastic was thought to be a boon but it turned out to be a curse. Plastic can be very harmful as it produces harmful gases when it is burned. As it is non bio degradable, it is harmful to the soil and takes hundreds of years to degrade or decompose.Plastic is a boon for man but it is a curse for the master. It makes life comfortable for man but life tiring for the environment. Once animals have eaten it and due to choking they diePlastic is very harmful to living things. We should decrease the use of plastic.In India use of plastic has been banned.Packaging represents the largest single sector of plastics use in the world today.Benefits of plastics-BoonThe considerable growth in plastic use is due to the beneficial properties of plastics. These include:Extreme versatility and ability to be tailored to meet very specific technical needs.Lighter weight than competing materials, reducing fuel consumption during transportation.Extreme durability.Resistance to chemicals, water and impact.Good safety and hygiene properties for food packaging.Excellent thermal and electrical insulation properties.Relatively inexpensive to produce.Plastics makes up around 7% of the average household dustbin.Effects of plastic-Curse.Plastics production also involves the use of potentially harmful chemicals, which are added as stabilisers or colorants. Many of these have not undergone environmental risk assessment and their impact on human health and the environment is currently uncertain. An example of this is phthalates, which are used in the manufacture of PVC. PVC has in the past been used in toys for young children and there has been concern that phthalates may be released when these toys are sucked (come into contact with saliva). Risk assessments of the effects of phthalates on the environment are currently being carried out.The disposal of plastics products also contributes significantly to their environmental impact. Because most plastics are non-degradable, they take a long time to break down, possibly up to hundreds of years - although no-one knows for certain as plastics haven't existed for long enough - when they are landfilled. With more and more plastics products, particularly plastics packaging, being disposed of soon after their purchase, the landfill space required by plastics waste is a growing concern.Plastic waste, such as plastic bags, often becomes litter. For example, nearly 57% of litter found on beaches in 2003 was plastic.Recycling plastic -Advantages.Conservation of non-renewable fossil fuels - Plastic production uses 8% of the world's oil production, 4% as feedstock and 4% during manufacture.Reduced consumption of energy.Reduced amounts of solid waste going to landfill.Reduced emissions of carbon-dioxide (CO2), nitrogen-oxide (NO) and sulphur-dioxide (SO2).
What effect does plastic utenstills pollution have on humans?
AnswerIn this era of many astonishing industrial developments, probably no industry has under gone such rapid growth and development as the plastics industry. According to most authorities in this field, the plastics industry really began in 1868. A young American printer, named John Wesley Hyatt, was searching for a new material to be used as a substitute for ivory in the making of billiard balls. This new plastic was called Bakelite. Many new plastics have been made since Bakelite. Production of plastics has increased over 2000% since Bakelite was first produced, and there are now more than twenty known types. Research along the lines of plastics has given a great impetus to research and invention in many other different fields of endeavor. Millions of dollars are spent yearly in plastics research, trying to find new plastics and to improve the existing ones. Much research will be done in the future to lower the cost of producing plastics so that their consumption will become greater. In spite of the varied and widespread application of plastics in practically every phase of everyday life, the possibilities of this wonderful new material have been by no means exhausted. It seems safe to say that if the application and use of plastics continue to increase at the present rate, we may be living in a "Plastics Age."An apt definition of plastics has been given by the head of the Monsanto Plastics Research who says, "Plastics are materials that, while being processed, can be pushed into almost any desired shape and then retain that shape."The major chemicals used to make plastic resins pose serious risks to public health and safety. Many of the chemicals used in large volumes to produce plastics are highly toxic.Some chemicals, like benzene and vinyl chloride, are known to cause cancer in humans; many tend to be gases and liquid hydrocarbons, which readily vaporize and pollute the air. Many are flammable and explosive. Even the plastic resins themselves are flammable and have contributed to numerous chemical accidents. The production of plastic emits substantial amounts of toxic chemicals(eg. ethylene oxide, benzene and xylenes) to air and water. Many of the toxic chemicals released in plastic production can cause cancer and birth defects and damage the nervous system, blood, kidneys and immune systems. These chemicals can also cause serious damage to ecosystems.Ethylene oxide is used as a sterilant in hospitals. It is also the principle metabolite of ethene, a precursor to polyethylene plastics and other synthetic chemicals. Ethylene oxide can be measured by gas chromatography in air or biological specimens. Ethylene oxide reacts in the body with hemoglobin.Many food containers for meats, fish, cheeses, yogurt, foam and clear clamshell containers, foam and rigid plates, clear bakery containers, packaging "peanuts," foam packaging, audio cassette housings, CD cases, disposable cutlery, and more are made of polystyrene. J. R. Withey in Environmental Health Perspectives 1976 Investigated styrene and vinyl chloride monomer as being similar: "Styrene monomer readily migrates from food contained in it. It makes no difference whether the food or drink is hot or cold, or contains fat or water. ...It is not inconceivable that the animal body behaves as a 'sink' for styrene monomer until the lipid portion of the animal body either becomes saturated (although death would probably occur prior to this event) or the tissues are equilibrated at the same concentration as the exposure atmosphere."PVC is used for many products including: flooring, toys, teethers, clothing, raincoats, shoes, building products like windows, siding and roofing, hospital blood bags, IV bags and other medical devices. One of it's major ingredients is chlorine. When chlorine-based chemicals are heated in the presence of hydrocarbons they create dioxin, a known carcinogen and endocrine disruptor. All PVC production releases dioxin. Other sources of dioxin are: production and use of chemicals, such as herbicides and wood preservatives, oil refining, burning coal and oil for energy, all car and truck exhaust, cigarettePlasticizers are used in PVC that migrate into a blood recipient via the blood bag, IV bag, IV tubing. Children's toys are made with pvc.Anyone who receives blood, is on kidney dialysis, or has tubes either inserted in them or has liquid or air transported to their body is at risk. About 85% of medical waste is incinerated, accounting for ten percent of all incineration in the U.S.Approximately five to fifteen percent of medical waste needs to be incinerated to prevent infectious disease. The remaining waste, while not posing any danger from infectious pathogens, is very dangerous when burned. It contains high volumes of chlorinated plastics including PVC (also the toxic substances mercury, arsenic, cadmium and lead.
