摘要：Atmospheric deposition data on trace elements from ten bulk sampler stations in the Venice Lagoon, covering a period spanning from 2007 to 2017, are presented and discussed. Results have been statistically analysed and used to estimate fall-out loads on the Lagoon. The Venice Lagoon is not only exposed to long-range transport of contaminants but it is also affected by local urban and industrial emissions. A sharp drop off of the Cd load since 2011 has been observed tied up with decreasing flux recorded at the station in the nearby glass-making district, where decreasing trends have also been detected for other elements. Decreasing long-term trends have been observed for Ni and Sb loads while Zn load has shown a small increase. The data analysis carried out in this study has proven the effectiveness of the bulk-collector-based surveys in detecting temporal and spatial changes in atmospheric depositions. The maintenance of this temporal data series will be a useful tool for evaluating future changes in the fall-out affecting the Venice Lagoon.
