Organic solvent neurotoxicity. Facts and research needs
Scandinavian Journal of Work, Environment & Health
|January 1, 1985
Summary
Organic solvents can cause acute narcotic effects, but few cause chronic nervous system damage. Chemical structure and exposure levels determine the type and severity of neurotoxicity, necessitating further research.
Area of Science:
- Neuroscience
- Toxicology
- Occupational Health
Background:
- Organic solvents are widely used in industry.
- High doses can cause reversible narcotic effects.
- Few solvents cause chronic or irreversible nervous system damage.
Purpose of the Study:
- To review the neurotoxic effects of organic solvents.
- To correlate chemical structure with neurological damage.
- To assess the reversibility of solvent-induced neurotoxicity.
Main Methods:
- Literature review of occupational exposure studies.
- Analysis of chemical structures and their neurotoxic properties.
- Examination of experimental animal studies on solvent ototoxicity.
Main Results:
- n-Hexane and methyl n-butyl ketone cause occupational neuropathy.
- Toluene abuse leads to irreversible brain damage, unlike occupational exposure.
- Trichloroethylene and its breakdown product dichloroacetylene damage the trigeminal nerve.
- Mixed solvent exposure may cause dementia and peripheral nerve dysfunction.
Conclusions:
- The neurotoxic effects of organic solvents vary based on chemical structure and exposure.
- Further clinical and experimental research is crucial due to the nervous system's vulnerability.

01:26Physical 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.
01:36Types 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.

01:26Toxic 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,...

01:17Antidotes
Antidotes are medicinal substances used to counteract the harmful effects of toxins or drugs in the body. They function in various ways, each uniquely designed to combat specific toxic compounds.
Specific antidotes operate by inhibiting the enzymes that control biochemical pathways, reducing the production of harmful metabolites.
An example of an antidote is atropine, which counteracts the detrimental effects of cholinesterase inhibitors. It achieves this by deactivating muscarinic receptors,...

01:23Toxicity Testing in Animals
Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
01:30Toxidromes: Clinical Features
Toxidromes are specific patterns of symptoms resulting from toxic substance exposure. They help in the identification and treatment of poisoning. The symptoms of each toxidrome group indicate poisoning by a certain class of chemicals or drugs.1. Sympathomimetic: Stimulates the sympathetic nervous system. Symptoms include agitation, increased heart rate (HR), blood pressure (BP), respiratory rate (RR), temperature, and pupil size. Drugs like cocaine and amphetamines, along with tremors and...
