BaSO4Dust

BaSO4Dust refers to particulate matter composed primarily of barium sulfate (BaSO4). It arises from processes involving barite ore, including mining, crushing, and handling, as well as the production and use of BaSO4-containing products such as drilling fluids, pigments, fillers, and radiographic contrast materials. In occupational and environmental contexts, the term is used to describe dust that may be generated during these activities.

BaSO4 is an inorganic salt that forms a white, crystalline powder with high density. It is practically insoluble in water and in most acids and is chemically inert under ordinary environmental conditions. Dust particles can span a range of sizes, and respirable fractions can become airborne during handling or processing.

Industrial relevance and safety: BaSO4 is widely used as a weighting agent in drilling muds, as a pigment or filler in paper, plastics and paints, and in certain radiopaque formulations for medical imaging. Dust from these processes can pose inhalation hazards if not properly controlled. Inhalation of fine BaSO4 dust can irritate the respiratory tract, and chronic exposure to respirable dust has been associated with baritosis, a benign radiographic finding that does not typically impair lung function. BaSO4 is not absorbed from the gastrointestinal tract, so ingestion is not expected to cause systemic toxicity. Standard occupational hygiene measures, including ventilation and personal protective equipment, are recommended to minimize exposure.
