The goal of the study was to develop a reliable field method using x-ray fluorescence (XRF) spectroscopy to measure levels of cadmium, chromium (total), and lead in marine paint during shipbuilding and repair activities, and to compare XRF sample results to traditional laboratory results. A reliable field method is desirable to reduce the time and cost associated with sending maritime paint samples to a lab for analysis prior to disturbance and/or repair activities, and to reduce the time needed to determine the proper level off employee protection prior to paint disturbance or removal operations. A total of 189 bulk paint samples were collected from Navy vessels at four shipbuilding and repair facilities by both shipyard personnel and industrial hygienists. After collection, samples were analyzed both on site and at an offsite laboratory. Results yielded no statistical significance between the XRF instruments and the laboratory analyses, meaning XRF technology can be used to inform decisions on the need for abatement or special precautions at job sites.
