Styrene and xylene (paints and solvents) Toluene (automotive) ... Cyanide toxicity may also disrupt a person’s breath, giving a “bitter almond” odor, but this may be hard to detect. Acute (short-term) exposure to styrene in humans results in mucous membrane and eye irritation, and gastrointestinal effects. The toxic effect gradually builds up over several weeks and is eliminated slowly. This article is for information only. The extent of the chemical Inhalation Injuries depends on a person’s exposure. Studies evaluating inhalation exposure have demonstrated that styrene is a strong irritant [1, 2].Eye, nose and throat irritation is common at exposure levels above 50 to 100 ppm but can also occur at levels of about 20 to 30 ppm [].At very high levels chronic bronchitis type symptoms and other respiratory symptoms appear. include fatigue, poor concentration, and drowsiness, among others.
