The Italian guidelines concerning the dumping of dredgingmaterials implies chemical, physical and microbiologicalcharacterisation of dumping sediments collected through aspecific sampling strategy.POP's such as PCB's and organochlorine pesticides, areconsidered as priority pollutants in all the InternationalConventions for the protection of the marine environment, inconsequence of their persistence, toxicity and bioaccumulation capacity.In the present article the concentrations and distribution ofPCB's and organochlorine pesticides in dredging sediments ofPiombino harbour (northern Thyrrenian sea) were investigates.The results showed high POP's concentrations in all the studiedareas. The maximum values were: 3.94 mg kg-1 dry weight for PCB's(IUPAC Nos. 28; 52; 101, 118; 137; 153; 180; 209); 2.04 mg kg-1 d.w.for HCH's (-, -, - and -hexachlorocyclohexane isomers); 0.28 mg kg-1 d.w. for DD's (DDT + DDE + DDD).Subsequently, the data related to each pollutant were treatedwith statistical tests, in order to verify how well the samplingstrategy is able to represent the distribution of contaminantsin the dredging area. Finally, management strategies werederived for the studied dredging sediments. 相似文献

Lichen, Usnea barbata, transplants taken from Tierra del Fuego (south Patagonia, Argentina) were tested as potential biomonitors of atmospheric
airborne deposition in an apparently pristine environment. In 2005, lichens were sampled in a reference site (n = 31) and transplanted in the northern Region of Tierra del Fuego. After, respectively, 1 month and 1 year of exposure, we
collected them. The aim of the study was to determine the bioaccumulation of 26 elements in order to evaluate the background
levels in the selected area. Samples were analyzed by the sector field inductively coupled plasma mass spectrometry. Discriminant
analysis on principal component analysis factors was applied in order to explore the relationship among the different elements
as far as time and spatial variation in transplants regards. The analysis was tested by Monte Carlo test based on 999 replicates.
The most important contamination source resulted to be the atmospheric soil particle deposition. Furthermore, the results
were compared with those obtained from the lichens collected in central and southern Tierra del Fuego. This study confirms
the ability of U. barbata to reflect the background levels of the 26 elements in that environment. Compared with other background sites in the world,
we did confirm that Tierra del Fuego lichens have a low content of the studied elements. Tierra del Fuego turned out not to
be a pristine environment as supposed, but it can be considered as a reference basal ecosystem for useful comparisons among
different geographical areas. These findings can be very relevant and useful for environmental conservation programs. 相似文献
