Dibutyl phthalate (DBP) is an organic compound which is commonly used as a plasticizer because of its low toxicity and wide liquid range. With the chemical formula C 6 H 4 (CO 2 C 4 H 9 ) 2 , it is a colorless oil, although impurities often render commercial samples yellow.
Phthalate esters usually refers to dialkyl esters of phthalic acid (also called 1,2-benzenedicarboxylic acid, not be confused with the structurally isomeric terephthalic or isophthalic acids); the name "phthalate" derives from phthalic acid, which itself is derived from the word "naphthalene". When added to plastics, phthalates allow the ...
Hazardous chemicals present physical and/or health threats to workers in clinical, industrial, and academic laboratories. Laboratory chemicals include cancer-causing agents (carcinogens), toxins (e.g., those affecting the liver, kidney, and nervous system), irritants, corrosives, sensitizers, as well as agents that act on the blood system or damage the lungs, skin, eyes, or mucous membranes.
Diisobutyl phthalate (DIBP) is a phthalate ester having the structural formula C 6 H 4 (COOCH 2 CH(CH 3) 2) 2. It is formed by the esterification of isobutanol and phthalic anhydride . This and other phthalates are used as plasticizers due to their flexibility and durability.
Occupational toxicology is the application of toxicology to chemical hazards in the workplace. It focuses on substances and conditions that people may be exposed to in workplaces, including inhalation and dermal exposures, which are most prevalent when discussing occupational toxicology.
The Deputy Assistant Secretary of the Navy for Research, Development, Test and Evaluation (abbreviated DASN (RDT&E) or DASN RDTE) serves as the principal adviser to the United States Assistant Secretary for Research, Development and Acquisition on all matters pertaining to science, technology, advanced research and development programs; system prototype programs; and management of science and ...
Illustration of Exposure Risk Assessment and Management related to anticipation, recognition, evaluation, control, and confirmation. Occupational hygiene or industrial hygiene (IH) is the anticipation, recognition, evaluation, control, and confirmation (ARECC) of protection from risks associated with exposures to hazards in, or arising from, the workplace that may result in injury, illness ...
Phthalate esters, common additives that soften and make PVC more flexible, are found in many everyday items such as medical devices, packaging for fragrances and cosmetics, ropes, varnishes, plastic food wraps, and shower curtains. Phthalate esters have been detected in water, air, sediment, and in bodies of water worldwide (Giam et al.). [5]
