it varies greatly from a few hours to several years. depends on the substance, the envirument its in and the surrounding flora and founa
The sigmoid colon is the last section of the colon and a person can function very well without it.
That's nasty, did you feel it or something? You probably have AIDS.
Biodegradable plastics can break apart into tiny pieces within a year, from weathering and ultraviolet solar radiation. Some non biodegradable plastics, like water bottles, buried in the earth, could survive largely intact for several billion years. Plastic foam cigarette butts typically last twenty to thirty years, if they are on the surface, exposed to the sun and elements. There is very wide variation.
The time can range from minutes to years depending on the environmental conditions and the type of material. Environment conditions may include temperature, humidity, pressure, type of organisms available to degrade the product, including bacterial, and sunlight Some materials degrade slowly or not at all or may be gone in weeks. A good example is an animal body. If mummified in a dry local it will last for centuries. In shallow warm ocean water it will be mostly gone in days.

Non-biodegradable substances can last forever. Some substances are slow to degrade, but they still degrade over time. Those that are non-biodegradable should not degrade, even over long periods of time.
it will not degrade and will last for long
Non-biodegradable substances can last forever. Some substances are slow to degrade, but they still degrade over time. Those that are non-biodegradable should not degrade, even over long periods of time.
Examples are plastics, metal and glass. Dangerous chemicals and toxins are also non-biodegradable, as are plastic grocery bags, Styrofoam (polystyrene), and other similar materials.
Aluminum is not biodegradable. and will last forever. Over a very longtime it may react chemically with other substances, similar to metal rusting, but the can will still be there in some form or shape.
timber is expected to last at list 15-25 years.
Forever. Wax is non-biodegradable.
No, they are biodegradable. So far, there has been no "bones" recovered from the Titanic wreck site as all the bones are now dissolved in the sea water or eaten by various sea organisms. The same happens over time in the earth. In some special cases the bones mineralize by replacing their structure with other inorganic materials. these fossilized bones last a long time.
Non biodegradable pollutants are very difficult to breakdown. They last for hundreds of years in the environment and affect nature negatively for long periods
Some will last around 4.5 billion years - until the sun becomes a red giant and effectively swallows the Earth.
Expected temperature, expected wind strength, expected relative humidity, last rainfall. Expected rainfall is not included.
It should be noted that conventional plastics can be made biodegradable with the inclusion of a small amount of an additive that promotes biodegradation. It is then called oxo-biodegradable plastic. Read more at http://biogreenproducts.com . Many plastic disposable products are being introduced that can be biodegraded using oxo-biodegradable technology.
