“…Similar gas-phase ΣPCB concentrations have been reported for the urban area of Integrated Atmospheric Deposition network (IADN) station, Chicago, as 1800 ± 170 pg m − 3 (Buehler et al, 2001). Tasdemir et al (2005) have reported that the average ΣPCB concentration in Chicago was 1900 ± 1700 pg m − 3 .…”

The air-water exchange of polychlorinated biphenyl (PCB) and organochlorine pesticides (OCPs) were investigated using paired air-water samples (n = 16) collected in July and February-March, 2005 from Guzelyali Port in Izmir Bay, Turkey. Atmospheric PCBs and OCPs were mainly in gas-phase in both periods. However, their dissolved and particle-phase water concentrations were comparable. For PCBs, 3 and 4-Cl congeners were dominant while chlorpyrifos, endosulfans and HCHs were the most abundant OCPs for all samples. Especially in summer, calculated net gas-exchange PCB fluxes were mainly volatilization from the water ranging from − 0.2 (volatilization, PCB-101) to −30.0 (volatilization, PCB-31) ng m − 2 day − 1 . For OCPs, net flux ranged from −0.03 (volatilization, cis-nonachlor) to 1568 (deposition, endosulfan I) ng m − 2 day − 1 and they have seasonal variations with generally deposition in winter and volatilization in summer. However, endosulfan I, II, endosulfan sulfate, α-and γ-HCH deposited in both periods. The calculated residence times of PCBs and OCPs in the water column indicated that the gasexchange in the Bay is at least as or a more important mechanism than advection. Annual gaseous absorption and volatilization fluxes were calculated and were used along with the estimated dry deposition fluxes and wet deposition fluxes measured recently at a suburban site in Izmir to determine the relative contributions of different atmospheric mechanisms to the pollutant inventory of the Bay water column. Results suggested that the relative contributions of all studied mechanisms to the water column PCB and OCP inventories were significant.

“…In fact, detailed analyses indicated that the PAH concentrations were especially elevated at Sturgeon Point when the winds blew from Buffalo (17 ). We can infer from these findings that Buffalo is a source of PCBs and PAHs at the Sturgeon Point location.…”

Currently, the concerns are with risk assessment, human health effects, and bioactive compounds as endocrine disruptors (DeCaprio, 1997;Hanselman, Graetz, & Wilkie, 2003;McArdell et al, 2003;Sexton, Needham, & Pirkle, 2004).…”

Mass spectrometry, especially coupled with gas chromatography or tandem, is the analytical method of choice in elucidations of biomarker compounds present in organic mixtures extracted from geological, environmental, or biological samples. This review describes the biomarker concept; i.e., the precursor natural products to the geological/environmental derivatives, and their application as tracers in the geosphere and ambient environment. The mass spectrometric methods currently utilized for such analyses are reviewed, and typical examples of applications are described with a general key to the literature. © 2004 Wiley Periodicals, Inc., Mass Spec Rev 24:719–765, 2005
