What Are the Symptoms of Solvent Poisoning?

Solvent poisoning can affect various bodily systems, with a primary impact on the central nervous system, leading to a range of symptoms from immediate irritation to life-threatening conditions.

Central Nervous System (CNS) Effects

The acute health effects of organic solvents often reflect their profound impact on the brain and nervous system. These symptoms can progress rapidly depending on the level and duration of exposure.

• Early and Mild CNS Symptoms:

  • Headache: A common initial symptom, often described as a dull ache or throbbing sensation.
  • Dizziness: A feeling of lightheadedness, unsteadiness, or a sensation of spinning.
  • Light-headedness: A feeling of faintness or an impending loss of consciousness.

• Progressive and Severe CNS Symptoms:
  If exposure is significant or prolonged, symptoms can escalate to severe conditions that require immediate medical attention.

  • Unconsciousness: A state of unresponsiveness and inability to be awakened.
  • Seizures: Uncontrolled electrical activity in the brain, leading to convulsions, muscle rigidity, and loss of consciousness.
  • Death: In severe cases, particularly with high levels of exposure or lack of timely intervention, solvent poisoning can be fatal.

Local Irritation Symptoms

Beyond systemic effects on the central nervous system, direct contact with or inhalation of solvent mixtures can also cause localized irritation to mucous membranes.

• Common Irritation:
  • Eye Irritation: Symptoms may include redness, burning, stinging, or excessive tearing of the eyes.
  • Nose Irritation: Discomfort, burning sensation, or irritation within the nasal passages.
  • Throat Irritation: Soreness, scratchiness, or a burning sensation in the throat, often accompanied by coughing.
