Do Solids Like Wood Produce Smells?

Click For Summary
SUMMARY

The discussion centers on the nature of smells produced by solid materials, particularly wood. It establishes that smells arise from volatile organic compounds that evaporate and interact with olfactory receptors. Specific examples include the characteristic scents of wood due to compounds like turpentine and resin, and the dangers of hydrogen sulfide gas, which can mask its rotten egg smell at high concentrations. The conversation emphasizes that smell is a sensory perception resulting from the brain's interpretation of airborne molecules.

PREREQUISITES
  • Understanding of olfaction and sensory perception
  • Knowledge of volatile organic compounds and their properties
  • Familiarity with the chemical reactions involving ammonia and hydrogen sulfide
  • Basic concepts of organic chemistry related to wood and its compounds
NEXT STEPS
  • Research the chemical composition of various types of wood and their characteristic smells
  • Learn about the olfactory system and how it processes different scents
  • Investigate the health effects of exposure to volatile organic compounds
  • Explore the role of organic compounds in plant defense mechanisms against decay and pests
USEFUL FOR

Individuals interested in botany, chemistry, sensory science, and environmental health, including researchers, educators, and anyone studying the interaction between solid materials and olfactory perception.

If so, what about smells coming from solid matter, like wood?

No, smell is a sense. That is like asking if taste is a food.

Some gasses can be detected by our sense of smell as can some aerosols. I don't know if the scent of wood is carried by a gas or an aerosol.
 
As DaleSpam said, smell is a sensory perception. It is an interpretation by our brain of the interaction of molecules (from gasses, aerosols, whatever) that hit the olefactory nerves.

There are some sensations that people THINK of as smells that actually are not. The best example I can think of is the reaction your nose has to ammonia. There is a bit of smell involved, but it is swamped by the predominant perception which is that of your mucus membranes being irritated by the chemical reaction they have with ammonia.

That is interesting. I did not know that.
 
Sometimes, certain smells can overwhelm your senses.

In low concentrations, hydrogen sulfide smells like rotten eggs. If the concentration of this gas goes above a certain limit, you lose the ability to perceive the rotten egg smell any longer, which can be dangerous. You might be surrounded by an atmosphere which has little or no oxygen available, and asphyxiation might result.
 
Wood contains many organic compounds such as turpentine, oil and resin. Each wood has a characteristic smell when cut. Smell is your sense detecting a few of the gas molecules of organic compounds that evaporate when exposed. These compounds often protect the tree from decay or digestion by insects.

Smell if you can, a piece of old wood, then scratch it and smell it again. You will smell the exposed organic molecules as they evaporate from the damaged cell structure.

Smell is something we detect with our sense of smell, much like sound is what we detect with our sense of hearing and light is what we detect with our sense of vision.

From Wikipedia:

An odor or odour or fragrance (commonly referred to as a smell) is caused by one or more volatilized chemical compounds, generally at a very low concentration, that humans or other animals perceive by the sense of olfaction.

So I guess this sums up what a smell is.

I don't think smell is something tangible but rather what we perceive in our brains. Indeed, such senses are aroused by stimuli and in the case of olfactory sense, it should be some thing in the air,

I believe that most smells are from gaseous molecules like benzene related or lipid based fragrances, bad smells of Sulphur dioxide or ammonia gas, which arise from volatile liquids or fumes. In many cases, the smell of the solid objects are from fumes released from the solid, for example the fungus on woods or volatile compound.

I am not sure about metals though if there isn't such thing described above.
