High Content Screening Analysis to Evaluate the Toxicological Effects of Harmful and Potentially Harmful Constituents (HPHC)
Published on: May 10, 2016
[Chemicals toxic to the olfactory system. Analysis and description]
Summary
Occupational exposure to chemicals can cause olfactory disorders, impacting smell function. Collecting precise epidemiological data on chemical toxicity is challenging due to multiple factors and varying testing methods.
Area of Science:
- Toxicology
- Occupational Health
- Neuroscience
Context:
- Chemical industry growth and pollution have increased occupational exposure.
- Olfactory disorders are a growing concern linked to environmental and industrial factors.
- Existing epidemiological data on olfactory toxicity is limited and complex.
Purpose:
- To review the challenges in assessing occupational olfactory toxicity.
- To differentiate between acute and chronic chemical toxicity affecting the olfactory system.
- To highlight limitations in current data collection and extrapolation methods.
Summary:
- Occupational exposure to chemicals poses a risk to the olfactory system, leading to disorders.
- Data collection is hindered by confounding factors, inconsistent olfactory testing, and difficulties in proving causality.
- Acute toxicity results from high-dose inhalation, while chronic toxicity from lower doses lacks protective respiratory reflexes.
Impact:
- Underscores the need for improved methodologies in occupational olfactory toxicity research.
- Highlights the difficulties in establishing direct cause-and-effect relationships for chemical exposures.
- Emphasizes the limitations of extrapolating animal model data to human olfactory responses.

Olfaction
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

Physical Properties of Amines
Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.
Types of Toxins
Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

Toxic Reactions: Overview
When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

Olfactory Receptors: Location and Structure
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
Physiology of Smell and Olfactory Pathway
Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.
