3. Ammonia
Ammonia is a colorless gas with a strong, pungent odor. It is produced naturally by the breakdown of organic matter, and it is also a common ingredient in cleaning products and fertilizers. When it comes to blood, ammonia is one of the volatile compounds that is released when hemoglobin breaks down. This is why blood has a characteristic ammonia-like smell.
- Decomposition
The smell of ammonia can be an indicator of decomposition. When blood decomposes, it releases a number of gases, including ammonia. The presence of ammonia can therefore help investigators to determine how long ago a person died.
- Blood Type
The smell of ammonia can also be used to determine a person's blood type. Type O blood has a higher concentration of ammonia than other blood types. This is because Type O blood does not have the A or B antigens, which bind to ammonia and prevent it from being released.
- Blood Loss
The smell of ammonia can also be used to estimate the amount of blood that has been lost. A strong smell of ammonia indicates that a person has lost a significant amount of blood.
- Evidence Collection
The smell of ammonia can be used to collect evidence at a crime scene. For example, if a suspect is covered in blood, the police can use a swab to collect the blood and then test it for the presence of ammonia. This can help to determine if the blood is human blood and if it came from the victim.
The smell of ammonia is a valuable tool for crime scene investigators. It can help them to determine how long ago a person died, what their blood type is, how much blood they have lost, and even if the blood came from the victim. This information can be crucial for solving a crime.
4. Raw meat
The smell of raw meat is often compared to the smell of blood. This is because raw meat contains a high concentration of hemoglobin, the protein in red blood cells that carries oxygen. When meat is cooked, the hemoglobin breaks down and the smell dissipates. However, when meat is raw, the hemoglobin is still intact and the smell is more pronounced.
The smell of raw meat can be important evidence at a crime scene. It can help investigators to determine where a crime took place and how much blood was shed. In some cases, the smell of raw meat can even be used to identify a victim or suspect.
For example, in one case, a woman was found dead in her apartment. The police found a pool of blood on the floor, but there was no sign of any injuries on the woman's body. However, the police did notice a strong smell of raw meat in the apartment. They later discovered that the woman had been killed by a blow to the head with a meat cleaver.
The smell of raw meat can also be a powerful psychological trigger. It can evoke feelings of fear, anxiety, and even nausea. For this reason, it is important for crime scene investigators to be aware of the potential psychological effects of the smell of raw meat and to take steps to minimize its impact on themselves and others.
5. Copper
Copper is a transition metal with a distinctive reddish-brown color. It is an excellent conductor of heat and electricity, and it is also malleable and ductile, making it easy to work with. Copper is found in a variety of minerals, including chalcopyrite, cuprite, and malachite. It is also found in small amounts in the human body, where it is essential for the production of red blood cells.
The smell of copper is often described as being metallic, pungent, or even slightly sweet. It is a distinctive smell that is often associated with the smell of blood. This is because copper is a component of hemoglobin, the protein in red blood cells that carries oxygen. When blood is exposed to air, the hemoglobin begins to break down, releasing copper ions. These copper ions react with oxygen to form copper oxide, which is what gives blood its characteristic metallic smell.
The smell of copper can be an important clue at a crime scene. It can help investigators to determine where a crime took place and how much blood was shed. In some cases, the smell of copper can even be used to identify a victim or suspect.
For example, in one case, a woman was found dead in her apartment. The police found a pool of blood on the floor, but there was no sign of any injuries on the woman's body. However, the police did notice a strong smell of copper in the apartment. They later discovered that the woman had been killed by a blow to the head with a copper pipe.
The smell of copper can also be a powerful psychological trigger. It can evoke feelings of fear, anxiety, and even nausea. For this reason, it is important for crime scene investigators to be aware of the potential psychological effects of the smell of copper and to take steps to minimize its impact on themselves and others.
6. Bleach
Bleach is a powerful chemical that is often used to whiten fabrics and disinfect surfaces. It is also a common ingredient in cleaning products and laundry detergents. Bleach has a strong, pungent odor that is often described as being similar to the smell of chlorine. This odor is caused by the presence of hypochlorite ions, which are the active ingredient in bleach.
- Deodorizing
Bleach is often used to deodorize areas that have been contaminated with blood. The hypochlorite ions in bleach react with the hemoglobin in blood, breaking it down and removing the odor. This can be helpful in cleaning up crime scenes, as well as in other situations where blood has been spilled.
- Disinfecting
Bleach is also a powerful disinfectant. It can kill bacteria, viruses, and fungi, making it an effective cleaner for surfaces that may have been contaminated with blood or other bodily fluids. This can help to prevent the spread of infection.

Bleach can also be used to destroy evidence at a crime scene. The hypochlorite ions in bleach can break down DNA, making it difficult to identify the person who left behind the blood. This can be a problem for investigators, as it can make it more difficult to solve a crime.
- Psychological Effects
The smell of bleach can be a powerful psychological trigger. It can evoke feelings of fear, anxiety, and even nausea. This is because bleach is often associated with death and violence. For this reason, it is important for crime scene investigators to be aware of the potential psychological effects of bleach and to take steps to minimize its impact on themselves and others.
Bleach is a powerful chemical that can be used for a variety of purposes. It is important to be aware of the potential benefits and risks of using bleach, especially in the context of a crime scene. Bleach can be a helpful tool for cleaning up and disinfecting, but it can also be used to destroy evidence and trigger psychological distress.
7. Sour
The sour smell of blood is often described as being similar to the smell of vinegar or lactic acid. This smell is caused by the presence of lactic acid, which is a byproduct of anaerobic respiration. When blood is exposed to air, the hemoglobin begins to break down, releasing lactic acid. The lactic acid then reacts with other compounds in the blood to produce a sour smell.
- Decomposition
The sour smell of blood can be an indicator of decomposition. As blood decomposes, the hemoglobin breaks down and releases lactic acid. The lactic acid then reacts with other compounds in the blood to produce a sour smell. The sour smell of blood can therefore help investigators to determine how long ago a person died.
