Generally associated with exposure to beryllium levels at or above 100 μg/m, it produces severe cough, sore nose and throat, weight loss, labored breathing, anorexia, and increased fatigue.
In addition to beryllium's toxicity when inhaled, when brought into contact with skin at relatively low doses, beryllium can cause local irritation and contact dermatitis, and contact with skin that has been scraped or cut may cause rashes or ulcers. Beryllium dust or powder can irritate the eyes.
