Putrefaction is one of seven stages of decomposition; as such, the term putrescible identifies all organic matter (animal and human) that is biochemically subject to putrefaction. In the matter of death by poisoning, the putrefaction of the body is chemically delayed by poisons such as antimony , arsenic , carbolic acid (phenol), nux vomica ...
The three characteristics of putrefaction are discoloration, disfiguration, and dissolution. There are many factors that could affect the rate of putrefaction in animals such as age, body composition, temperature, and if the body is located in a wet or dry area. [8] Temperature must be between 0 °C and 48 °C for putrefaction to occur.
Technique: Body cooling (measure body cooling to estimate time since death) Pigs: stages of body cooling after death. In pigs, the decrease in body temperature occurs in the eyeball, orbit soft tissue, rectum, and muscle tissue. [29] Up to 13 hours after death, eyeball cooling in pigs provides a reasonable estimate of time since death. [30]
A decomposing human body in the earth will eventually release approximately 32 g (1.1 oz) of nitrogen, 10 g (0.35 oz) of phosphorus, 4 g (0.14 oz) of potassium, and 1 g (0.035 oz) of magnesium for every kilogram of dry body mass, making changes in the chemistry of the soil around it that may persist for years.

When considering cadavers and carcasses, putrefaction is the proliferation of microorganisms within the body following death and also encompasses the breakdown of tissues brought upon by the growth of bacteria. The first signs of putrefaction are usually the discolorations of the body which can vary between shades of green, blue, red or black ...
The human body is composed of approximately: 64% water, 20% protein, 10% fat, 1% carbohydrate, 5% minerals. [1] The decomposition of soft tissue is characterized by the breakdown of these macromolecules, and thus a large proportion of the decomposition products should reflect the amount of protein and fat content initially present in the body. [4]
Along with common factors of temperature, humidity and element exposure, body habitus and clothing are an example of a component that can affect the rate of cooling of the body, and so its rate of decomposition. [5] [6] A very approximate rule of thumb for estimating the postmortem interval is as follows: [7] Warm and flaccid: less than 3 hours
With his work he wanted to highlight the horrifying aspects of the existence within these realms. The kusōzu were chosen to represent the impure aspect of human existence as the impurity can be understood through the decay of a corpse. [16] He states: "it is odorous and defiled [...]. But, if it is seen, all desires [for the body] cease." [17]
