“…Smaller sample sizes become important when dealing with real life problems, such as alleged contamination, consumer complaints, and safety risk assessments. Also, and since losses of PAHs from PM collected on filters are more significant for the compounds containing less than five rings when the sampling time exceeds 24 h [39], the concentrations reported will be a good estimation of the environmental levels. The toxicity of PAHs justifies the need to establish their content in urban PM.…”

A methodology based on microwave-assisted extraction (MAE) and LC with fluorescence detection (FLD) was investigated for the efficient determination of 15 polycyclic aromatic hydrocarbons (PAHs) regarded as priority pollutants by the US Environmental Protection Agency and dibenzo(a,l)pyrene in atmospheric particulate samples. PAHs were successfully extracted from real outdoor particulate matter (PM) samples with recoveries ranging from 81.4 l 8.8 to 112.0 l 1.1%, for all the compounds except for naphthalene (62.3 l 18.0%) and anthracene (67.3 l 5.7%), under the optimum MAE conditions (30.0 mL of ACN for 20 min at 1108C). No clean-up steps were necessary prior to LC analysis. LOQs ranging from 0.0054 ng/m 3 for benzo(a)anthracene to 0.089 ng/m 3 for naphthalene were reached. The validated MAE methodology was applied to the determination of PAHs from a set of real world PM samples collected in Oporto (north of Portugal). The sum of particulate-bound PAHs in outdoor PM ranged from 2.5 and 28 ng/m 3 .

“…Detailed description of the Box -Behnken design. ringer and Suich [28,29,36,37] allowing equalization of the magnitudes of analysis time and resolution averages of the four pairs studied, avoiding that one of them represent an excess weight in relation to the others. The codification of both analysis time and resolution average was carried out in order to adjust the values on a scale from 0 to 1, both of them being of the same order of magnitude.…”

This paper describes the development and optimization, by using multivariate analysis, of a GC -MS-SIM method for evaluation of the 16 polyaromatic hydrocarbons considered as priority pollutants in atmospheric particulate material by the US EPA. In order to assure an adequate separation in the shortest analysis time, a multivariate design was used to set the conditions of the oven temperature program. The optimization process was carried out using factorial fractional design and BoxBehnken design. The following factors were evaluated: initial temperature, temperature rate #1, intermediary temperature, temperature rate #2, and final temperature. The optimized conditions were set at: 708C (2 min) 2008C (308C/min, 5 min) 3008C (58C/min, 1.67 min). Moreover, we have also optimized the injector temperature as 3108C and sampling time as 0.8 min. The total analysis time was 33 min. Validation of GC -MS-SIM yielded satisfactory results for repetitivity of the detector response and retention times, and linearity of calibration curves. LOD were established as 0.13 -0.34 ng/mL (peak area) and 0.18 -0.72 ng/mL (peak height). The method has been shown to be appropriate for the analysis of samples of atmospheric particulate material and/or other environmental matrices.

“…In the second sampling, less than 5% of the pyrene was found in 54% (n = 24) of XAD-2 samples. The outdoor temperature was approximately -20°C during the winter sampling days, and it is known that temperature has a considerable influence on the occurrence of smaller PAHs in particulate or gaseous phase in the atmosphere (21). Correlation between pyrene and B[a]P concentrations was, however, very good ( Figure 1).…”

were 5.7 pg/M3 and 8.1 pg/M3, respectively. Based on skin wipe sample analyses, the skin contamination was also obvious. The mean value of benzo[alpyrene on the samples collected after the shift was 1.2 ng/cm2. In control samples, benzo[alpyrene was not found. The mean value of urinary 1-hydroxypyrene concentration was 6.0 nmol/mmol creatinine for the exposed workers and 0.5 nmol/mmol creatinine for the controls. This study showed the usefulness of 1 -hydroxypyrene as an indicator of internal dose of polynuclear aromatic hydrocarbons. We concluded that the cokery workers at the Kohtla-J3rve plant are exposed to high concentrations of polynuclear aromatic compounds. Environ Health Perspect 104(Suppl 3): 539-541 (1996)
