“…The r 2 values for the two methods were 0.972, 0.964, and 0.982 in the three types of lead-using industry, also with no significant differences being present. Our results are similar to those obtained in previous FPXRF studies 3,4,[23][24][25] . Morley et al reported that the regression coefficient for data near PEL was less than 1 (i.e., 0.826), with a positive method bias due to the high detection limit of FPXRF, and considered that applying FPXRF methods rather than the standard laboratory method would help to protect workers.…”

-We evaluated the possibility of applying field-portable x-ray fluorescence (FPXRF) analysis as a rapid, on-site and near real-time method for evaluating airborne lead contamination in Korean workplaces. A total of 287 airborne lead filter samples were measured in 12 leadusing workplaces during routine industrial hygienic monitoring procedures as required by Korean government regulations. All filter samples were collected using the standard industrial hygiene sampling protocol described in NIOSH Method 7300 using closed-face 37-mm cassettes with preloaded cellulose ester membrane filters with a pore size of 0.8 µm. The samples were first analyzed using the nondestructive, FPXRF analytical method (NIOSH method 7702), and then subsequently analyzed using inductively coupled plasma atomic emission spectrophotometry (ICP) (NIOSH method 7300) as a reference analytical method. Pair-wise comparison of filter samples using the paired t-test revealed no statistically significant differences between the two methods over a wide range of airborne lead levels (0.018-0.201 µg/m 3 ) either over the industries assessed or separately in the 12 lead-using workplaces. Linear regression of the data between the ICP and FPXRF methods produced a slope of 1.03, a y-intercept of 0.13 µg/sample, and a coefficient of determinant (r 2 ) of 0.975 for all the data. For samples in the range from 0 to 100 µg, the corresponding values were 1.07, -1.20 µg/sample, and 0.925, respectively. There were no significant differences in the regression analyses of the three industry types (r 2 =0.964-0.982). Our data suggest that FPXRF data are highly correlated with those from the laboratory-based ICP method in terms of accuracy, precision, and bias. Therefore, FPXRF can be used for the rapid, on-site analysis of lead air-filter samples for values up to 26 µg/sample prior to laboratory confirmation by the ICP method.

“…Field portable XRF spectrometers can also be used for rapid and accurate determinations of elements, such as silicon and phosphorus in plants (Reidinger et al, 2012), for analyzing dust wipe samples (Sterling et al, 2000) or rock and mineral specimens (Yuan et al, 2014). Determinations of lead in environmental samples, especially in heavily polluted areas are one of the main applications of portable XRF spectrometer (Drake et al, 2003;Schwarz et al, 2012;Scott et al, 2013).…”

“…It is estimated that about 1000 measurements per day can be taken by a single instrument, providing valuable data, especially for heterogeneous soils which are physically disturbed and polluted, such as those in the mining areas or industrial brownfields (Drake et al, 2003;González-Corrochano et al, 2014).…”
