摘要

This paper presents the results of total chromiumfugitive emissions measurements above a hard chromiumelectroplating tank at the Marine Corps Logistics Base (MCLB) inAlbany, GA. The measurements were made using OSHA DraftMethod ID-215 and a newly developed real-time monitor based onspark-induced breakdown spectroscopy (SIBS). The SIBS monitoracquired data on a five-sec time scale and was used to survey thetotal chromium concentrations above the plating bath surface overa range of ventilation rates in conjunction with operation of anexperimental liquid recirculation system. The SIBS-measuredconcentrations varied from <10#mu#g/m~3 (the lower limit ofdetection) to >1000<10#mu#g/m~3. The measured concentrationswere well correlated to distance from the plating bath surface,smoke test indications of poorly ventilated areas and ventilationflow rate. The SIBS data quantitatively agree with simultaneousinternal filter results and with the OSHA-approved air samplingfilter measurements. These results indicate the SIBS monitor iscapable of industrial hygiene monitoring of chromium in a plating environment.
