Atomic Structure of Surfaces and Ultrathin Films

Structural and electronic properties of surfaces and ultrathin metallic films are closely connected. Because of their low dimensionality it is of the utmost importance to acquire their structural details at atomic level and their electronic structure resolved in energy and momentum at very high resolution. In this paper, we briefly review several experimental examples that illustrate these requirements and at the same time address some important properties of surfaces and ultrathin films. The examples are restricted to those that used scanning tunneling microscopy to study the structural properties and ultraviolet photoemission spectroscopy to elucidate the electronic structure of the samples

Monitoring of sea contamination by chlorinated hydrocarbons in the Kaštela bay using mussels as bioindicators

U svrhu procjene biološke dostupnosti kloriranih ugljikovodika u morskom okolišu Kaštelanskog zaljeva primijenjena je metoda aktivnog praćenja koristeći dagnje Mytilus galloprovincialis, uzorkovane na čistom području Malostonskog zaljeva i preseljene na područje istraživanja. Praćena je prostorna i vremenska raspodjela kloriranih ugljikovodika ovisno o njihovim fizikalno-kemijskim svojstvima, okolišnim i biološkim čimbenicima.To assess a bioavailability of chlorinated hydrocarbons in the sea environment of the Kaštela Bay an active monitoring method was used. For that purpose mussels Mytilus galloprovincialis were collected from the clean area of Mali Ston Bay and transplanted to the Kaštela Bay. The spatial and temporal distribution of chlorinated hydrocarbons was examined in relation to physico-chemical properties of contaminants, environmental and biological parameters

Organochlorines Accumulation in Caged Mussels Mytilus galloprovincialis—Possible Influence of Biological Parameters

The accumulation of organochlorines (OCs) in mussel tissue depends on the physiological and biochemical status of the organism and its interaction with the environment. Mytilus galloprovincialis, 2- and 1-year-old mussels, sampled from Mali Ston Bay, a reference area, and transplanted to Kaštela Bay in cages, were used for the assessment of OC levels and influence of biological parameters on accumulation. Results of bimonthly exposures during one year highlighted that OC accumulation decreases with increasing mussel age. Polychlorinated biphenyls (PCBs) and p,p′-dichlorodiphenyltrichloroethane (p,p′-DDTs) increased, while organochlorine pesticide (OCP; i.e., HCB, lindane, heptachlor, and aldrin) variations were very low. Statistical analysis generally did not confirm the significant effect of lipid content on the accumulation of OCs in mussel tissue. OC levels in mussels were below the maximum permitted levels for human consumption (European Commission)

CHLORINATED HYDROCARBONS IN MUSSELS AND SEDIMENTS FROM THE MIDDLE ADRIATIC COASTAL WATERS

Abstract Mussels and sediments from the Middle Adriatic coastal waters were analysed in order to assess the present level of contamination by chlorinated hydrocarbons. The concentrations of PCBs and DDTs were generally higher in mussels than in sediments at all locations. Moreover, higher PCBs concentration, both in mussels and sediments, reflected the prevailing influence of industrial sources of contamination over agricultural ones. In conclusion, the obtained data indicated a low level of contamination of the Middle Adriatic coastal area

Review of the Commission Decision 2010/477/EU concerning MSFD criteria for assessing Good Environmental Status: Descriptor 9 Contaminants in fish and other seafood for human consumption do not exceed levels established by Community legislation or other relevant standards

This report represents the result of the scientific and technical review of Commission Decision 2010/477/EU in relation to Descriptor 9. The review has been carried out by the EC JRC together with experts nominated by EU Member States, and has considered contributions from the GES Working Group in accordance with the roadmap set out in the MSFD implementation strategy (agreed on at the 11th CIS MSCG meeting). The report is one of a series of reports (review manuals) including Descriptor 1, 2, 5, 7, 8, 9, 10 that conclude phase 1 of the review process and, as agreed within the MSFD Common Implementation Strategy, are the basis for review phase 2, towards an eventual revision of the Commission Decision 2010/477/EU. The report presents the state of the technical discussions as of 30 April 2015 (document version 8.0: ComDecRev_D9_V8), as some discussions are ongoing, it does not contain agreed conclusions on all issues. The views expressed in the document do not necessarily represent the views of the European Commission.JRC.H.1-Water Resource
