Respiratory Hazards of Diacetyl and 2,3-pentanedione Exposure in the Coffee Roasting Industry
During coffee production of both flavored and unflavored coffee, production employees become exposed to dangerous VOCs resulting in irreversible lung damage (Ref. 1). The most hazardous VOCs released from flavorings and naturally from roasting coffee beans are diacetyl and 2,3-pentanedione. Exposure to even small amounts over time or large concentrations over a short period… Learn More
Laboratory Fume Hoods
Laboratory fume hoods provide operator and environmental protection from hazardous fumes, particulate, and other gases. Through inhalation, harmful fumes directly enter the blood stream and small particles may become embedded deep within the lungs (Ref. 1). A laboratory fume hood reduces exposure by containing the fumes and particulate dispersed during an experiment and a… Learn More
Toxicity of methyl methacrylate in dentistry
Initially, denture teeth were made of ceramic material. With the advent of polymethyl methacrylate (PMMA) in the 1940s, a new material was introduced for the fabrication of denture teeth. Denture teeth are currently made of either methacrylate-based resins (acrylic resin) or ceramics. Loss of teeth, which may be due to trauma, dental diseases, pathology, or… Learn More
Hydrochloric acid health risks: vapor, mist, and fume inhalation
What is Hydrochloric Acid? Hydrochloric acid is a colorless, corrosive, liquid that fumes in air at high concentrations of 25% or more, and becomes a hydrogen chloride gas forming dense white vapors due to condensation with atmospheric moisture (Pubchem). The vapor is corrosive, and air concentrations above 5 ppm can cause irritation. Hydrogen chloride is… Learn More
