Seasonal variations of polychlorinated biphenyls in ambient air in Zagreb, Croatia.

چکیده
Levels of polychlorinated byphenils (PCBs) were monitored continuously in Zagreb between June 1999 and February 2000 and analysed qualitatively and quantitatively using high resolution gas chromatography (HRGC). Total PCBs were determined with respect to Aroclor 1260, which was used as the standard reference. The concentrations of PCBs ranged from 1.6 to 136 pg/m3 and were higher in warmer seasons (temperatures above 10 degrees C; 5.1-136 pg/m3) than in colder seasons (temperatures from -10 degrees C to about 10 degrees C; PCB range: 1.6-23.5 pg/m3). The increase in PCBs concentration with temperature followed an exponential curve.

We studied the occurrence and levels of hexachlorobenzene, -, -, and -hexachlorocyclohexane, 4,4'-DDT, 4,4'-DDE, 4,4'-DDD, and 17 PCBs (six indicator and eleven other toxicologically significant congeners) in PM10 and/or PM2.5 particle fractions collected between 2000 and 2003 and in 2010 at a site in the northern residential part of Zagreb, Croatia. Twenty-four-hour particle samples were co...

A gas-chromatographic method on capillary columns is described for measuring concentrations of total PCBs and of six PCB congeners, PCB-28, PCB-52, PCB-101, PCB-138, PCB-153 and PCB-180, in human blood serum. Recovery of compounds was evaluated, and the repeatability and reproducibility of the results tested on samples analysed on the same day and over a period of two years. The method was veri...

PM2.5, total suspended particles (TSP) and gas phase samples were collected at two sites of Taizhou, a major e-waste dismantling area in China. Concentrations, seasonal variations, congener profiles, gas-particle partitioning and size distribution of the atmospheric polychlorinated biphenyls (PCBs) were studied to assess the current state of atmospheric PCBs after the phase out of massive histo...

Polychlorinated Biphenyls (PCBs) have been widely used to flame-retard products common in homes and theworkplace, and subsequently. Polychlorinated biphenyls (PCBs) typify a class of highly toxic, stable aromaticpollutants. PCBs are recently being scrutinized for potential environment damage in groundwater and in theatmosphere. The elimination of chemical pollutants from a contaminated environm...

Monitoring of isotope distribution in the atmosphere included isotopes 2H, 3H and 18O in precipitation, and 13C and 14C in atmospheric CO2. This paper presents the results of atmospheric monitoring over Croatia and Slovenia overt the last few years. Monthly precipitations in Zagreb and Ljubljana had been collected since 1976 and 1981, respectively. Between 2000 and 2003 monitoring also included...
