There is no public health benefit to embalming and it is practiced purely for cosmetic purposes; however, in some places, it is prohibited to embalm a person who died from a serious contagious disease. The rate of decomposition is largely dependent on the cause of death, the weight of the deceased and other environmental factors.
For example, bodies decay at a faster rate if they are exposed to the elements or wildlife, if they are in warm environments, or if they are under water. This is why forensic scientists created body farms warning: article contains image of human decomposition to study human decomposition rates under various conditions.
Below, we focus on the decomposition process without embalming when a body is in a neutral climate, not in a coffin, and the remains are undisturbed. Eventually, the last stage of decomposition is skeletonization, which leaves behind nothing but, you guessed it, a skeleton. This can take anywhere from 1 month to several years, depending on the environment, burial, etc.
You may be wondering: will a skeleton also decompose? A human taphonomy facility where the decomposition of human remains are studied would boost forensic research.
The development of a VOC profile for decomposing bodies should help scientists working to create an electronic nose, which are hardier than dogs and do not need costly training and upkeep. Sniffer dogs are more adaptable than their e-nose counterparts, however, and by entering dangerous places alone they help to keep their handlers safe.
