- Abstract
- The concentrations of gas-phase PCBs were measured from March 2002 to June 2003 at two sites of the Venice Lagoon and at one site of the Euganei hills. The aims of this study were to evaluate the various gas-phase PCB sources, the spatial and temporal variability of PCB concentrations in the gas-phase that enter the Venice Lagoon atmosphere and the influence of the air temperature on PCB trends. The highest annual average concentration of Sigma PCBs was observed at the station directly influenced by \"urban\" sources with values about 3 and 1.5 times higher compared to the concentrations found at the stations where \"marine\" sources and \"not subjected to direct local sources\" were respectively sampled from.
The temporal trends of Sigma PCBs concentrations were similar at the three sampling stations corresponding to seasonal temperature changes. Greater concentrations occurred in the summer and first autumn months while the lower ones occurred in late autumn and winter. The temperature dependences were investigated using plots of the natural logarithm of the Sigma PCBs concentrations vs. reciprocal mean temperatures. (c) 2005 Elsevier Ltd.
