“…1). The minimum recovery for PCBs after 24 hours Soxhlet extraction was reported as 63% [17,30] while 96% was obtained in this work. In this work, the minimum recoveries were obtained as 72 and 62% for PAHs and OCPs, respectively.…”

“…There are various studies reporting n-hexane:diethyl ether (9/1, v/v) [26 -27], dichloromethane:petroleum ether (1/4, v/v) [19,28,29], n-hexane:dichloromethane (9/1, v/v) [17,30], dichloromethane [23, 31 -33] in the extraction of PAHs, PCBs and OCPs from airborne particles by using Soxhlet extraction. At the beginning of this study, the extraction efficiency of n-hexane:diethyl ether (9/1, v/v), dichloromethane:-petroleum ether (1/4, v/v), and n-hexane:petroleum ether (1/1, v/v) were compared.…”

“…Blank samples (including six pre-cleaned filters) were prepared, treated and analyzed in the same manner as the real samples. The limit of method detection (MDL) was defined as the mean blank mass + three standard deviations [17,28,36,37]. No peaks matching the target compounds were found on blank filters.…”

Ultrasonic solvent extraction of persistent organic pollutants including polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and organochlorine pesticides (OCPs) from airborne particles is reported. The extraction was optimized as functions of type and amount of solvent, sonication time, and number of extraction steps. Determination of PAHs and PCBs carried out by GC/MSD, while OCPs were determined using GC/l-ECD. The optimum extraction procedure was determined as three times consecutive extraction using a 25 mL mixture of n-hexane:petroleum ether (1/1, v/v) for 15 min of sonication. Recoveries were obtained between 91 l 2 and 96 l 1% with Relative Standard Deviation (RSD) f l 4% for PCBs, for PAHs recoveries (except for naphthalene, a 31%) were between 66 l 6 and 90 l 4% with RSD f l 8% while OCPs compounds recoveries were between 67 l 5 and 120 l 7% with RSD f l 7%. When comparing the Soxhlet extraction method with optimized ultrasonic solvent extraction method, extraction time and solvent volume were reduced considerably with the ultrasonic solvent extraction method without reducing extraction efficiency. In addition, a simultaneous analysis of PCBs, PAHs, and OCPs in one sampling by the optimized method is quite advantageous in terms of analysis time and cost.

“…Backup filters were not used in this study. However, a recent study indicated that the percent mass on the second filter was not significant (below 10%) for OCPs (Yeo et al, 2003). In the present study, since the sampling was conducted during relatively short periods (12 h, day or nighttime) the temperature fluctuations were also minimized.…”

The concentrations of organochlorine pesticides (OCPs) in both the gas and particulate phases of urban air samples were determined. The samples were collected between August 2006 and May 2007 at four different locations in Konya, Turkey. OCPs were analyzed by gas chromatography with micro electron capture detection (GC/μ‐ECD). The average total (gas + particulate) concentrations of OCPs were determined to be between 809 and 6309 pg/m3. The highest OCP levels were found in autumn. Total hexachlorocyclohexane (HCH, sum of α, β, γ, δ‐HCH), total DDT's (sum of p,pi‐DDT, p,pi‐DDD and p,pi‐DDE) and endosulfan compounds (sum of endosulfan I, endosulfan II and endosulfan sulfate) were about 43, 25 and 17% of total OCPs, respectively. OCPs were predominantly detected in the particulate phase. Correlations were observed between OCP concentration and temperature, relative humidity, wind speed and Total Suspended Particulate, PM10, but the variation between meteorological parameters with OCP concentrations could not be explained completely. Despite banned/restricted use in Turkey, all the OCPs were found in urban air. p,pi‐DDT/p,pi‐DDE ratios were above 11 which is an indication of current use of DDT compounds. Therefore, it could be suggested that Konya is an actively contributing region to organochlorine pesticides pollutants in Turkey.
