This week we welcome ACGIH Chair Mary Lopez, PhD, CPE and Immediate Past Chair Mike Ellenbecker, ScD, CIH to Iaqradio+. Our topic is how scientific organizations like ACGIH develop guidelines such as Threshold Limit Values using science as driving force behind development. Guidelines and standards are developed by many organizations lets look at how one of the most respected organizations in the world does it.
