Prosector
Generally, the risks to prosectors are low. Cadavers used for teaching purposes are embalmed before they are encountered by a prosector and students. Embalming fluid usually contains formaldehyde, phenol, Dettol, and glycerine which disinfect and kill pathogens within the cadaver. With exposure to embalming fluid, tissues and bodily fluids, such as blood, become fixed. Prosectors and students working with embalmed cadavers must always wear protective gloves, however this is more for protection against the harsh chemicals used in embalming such as formaldehyde and dettol which can cause moderate to severe skin irritation.
Embalming chemicals
When an embalmed body is buried and decays, the embalming fluid can seep into the ground and affect the surrounding soil and water ecosystems. Since embalming fluid largely consists of formaldehyde, it is the chemical that has the most dramatic effect on its surroundings. The fluid that is injected into the blood vessels of the cadaver is up to 5% formaldehyde while the fluid injected into the body cavity is up to 37%.
