How is carbon black measured in the work environment?
Carbon black is commonly measured in work atmospheres by general gravimetric methods that collect air samples in the breathing zone of workers over a representative portion of the work shift. In work atmospheres that may contain a dust mixture that includes carbon black, specific methods to measure the elemental carbon composition of the breathing zone sample have been developed by OSHA and NIOSH. An industrial hygienist should be consulted to recommend the sampling and analytical method that is most appropriate.
