TLV Basis: Pneumoconiosis; "Therefore, because barium sulfate is a relatively low toxicity particle, but high levels of particles can cause inflammation or a benign pneumoconiosis, a TLV-TWA of 5 mg/m3 or inhalable particulate matter containing no asbestos and < 1% crystalline silica is recommended." [ACGIH] See the disease "Pneumoconioses, benign."
