Heavy metal background levels and pollution temporal trend assessment within the marine sediments facing a brownfield area (Gulf of Pozzuoli, Southern Italy).

In this study, site-specific natural background levels (NBLs) were determined for 18 elements (Al, As, Be, Cd, Co, Cu, Cr, Fe, Hg, K, Mn, Mo, Ni, Pb, Tl, U, V, and Zn) in two sediment cores collected offshore the Bagnoli-Coroglio brownfield site (Gulf of Pozzuoli, southern Italy) to accurately assess the degree of contamination and the historical trends in Heavy Metals (HMs) enrichment. This objective was pursued taking in account the high temporal and spatial variability of the geochemical properties of the area due to the local geothermal activity. Moreover, the temporal variation of Polycyclic Aromatic Hydrocarbons (PAHs) was investigated.

Gathering new knowledge from existing monitoring dataset of Campania marine coastal area (Southern Italy).

In this study we propose, a multi-step strategy of selection and characterization of long-term dataset of contaminant concentrations in different environmental matrices (i.e., water and sediment).

Heavy metal content and potential ecological risk assessment of sediments from Khnifiss Lagoon National Park (Morocco).

Coastal lagoons are important but sensitive environments, being transitional zones between land and sea. The Khnifiss lagoon is the most important desert wetland in Morocco, but little data have been produced concerning heavy metal geochemistry and enrichments in the sediments. Therefore, 26 surface sediments (15 intertidal and 11 subtidal) and 2 sediment cores were collected in 2016 and analyzed for a selection of heavy metals.

Fluorine in the rocks and sediments of volcanic areas in central Italy: total content, enrichment and leaching processes and a hypothesis on the vulnerability of the related aquifers.

Rock, sediment and water samples from areas characterised by hydrothermal alterations in the Sabatini and Vico Volcanic Districts, near Rome and the large city of Viterbo, respectively, were collected and analysed to determine the total fluorine (F) content and to understand the F geochemical background level in the volcanic districts of central Italy. Leaching and alteration processes controlling the high concentration of F in water were also investigated. Fluorine concentrations were directly determined (potentiometrically) by an F selective electrode in water samples, while the procedure for rock samples included preliminary F dissolution through alkaline fusion.

Impact of alcohol consumption on winter sports-related injuries.

Introduction: This study was carried out to evaluate data about trauma-related winter sports, including risk factors such as high speed, gender, age, alcohol consumption, details about the accident and snow conditions.

Methods: A retrospective review was conducted to determine the injury patterns and crash circumstances in holiday skiers and snowboarders. The data recorded were obtained from the database of the Pre-Hospital Emergency Registry of six skiing areas in the Dolomite mountains during the winter seasons November 2004-May 2009, injury data for major traumas from Ski Patrol Injury reports (helicopter, ambulance or ski slopes' patrol reports), and intrahospital Emergency Department data.
