Evaluation of Parameters Influencing Hexavalent Chromium Mist Sampling: A Full Factorial Design

A chromium electroplating bath with the ability to produce homogenous mist was used to evaluate parameters influencing hexavalent chromium (Cr+6) mist sampling methods. The results of 48 Cr+6mist samples collected using the U.S. National Institute for Occupational Safety and Health method 7600showed...

Zusammenfassung:A chromium electroplating bath with the ability to produce homogenous mist was used to evaluate parameters influencing hexavalent chromium (Cr+6) mist sampling methods. The results of 48 Cr+6mist samples collected using the U.S. National Institute for Occupational Safety and Health method 7600showed that Cr+6concentration was higher: (1) For sampling by closed-face filter cassettes than for sampling by open-face filter cassettes (P
