The editors of the NIOSH Manual of Analytical Methods, or NMAM, are seeking feedback about the 5th edition of the resource. NMAM is a compilation of validated sampling and analytical methods that are used globally for occupational exposure assessment in industrial hygiene and related professions. The 5th edition of NMAM was released in April 2016 and has been continuously updated as new or revised methods are evaluated and their performance verified. The NMAM editors are conducting a survey to gather information about how customers use analytical methods in their work and their use of NMAM. According to NIOSH, the survey results will be used to help focus future method development activities, improve NMAM methods, and identify website content or features in need of improvement. The NMAM survey—available through Dec. 31, 2019—is anonymous, according to NIOSH, and no individually identifiable data will be collected, published, or released. Learn more on NIOSH's website.
