A new approach for environmental damage assessment pursuant to the European Union Environmental Liability Directive.

The European Union and Member States national laws require competent authorities to promptly and effectively address environmental incidents, noncompliances, and criminal offenses, necessitating thorough planning of investigation and assessment activities. To enhance environmental damage assessments in line with the European Environmental Liability Directive (ELD, 2004/35/EC), the European Union Network for the Implementation and Enforcement of Environmental Law (IMPEL Network) has introduced the Criteria for the Assessment of the Environmental Damage (CAED) framework. This framework, outlined in a Practical Guide, offers a methodological approach to environmental damage assessment (EDA) focusing on three key objectives: case screening, identification of "clues" of damage, and determination of "evidence" of damage.

Hepato-renal toxicity of low dose metal(oid)s mixture in real-life risk simulation in rats: Effects on Nrf2/HO-1 signalling and redox status.

The understanding that humans are exposed to a low level of toxic metals and metalloids in their lifetime has resulted in a shift in scientific and regulatory perspectives from the traditional evaluation of single metal toxicity to complex mixtures, relevant to real-life exposure. Therefore, the aim of this study was to examine the impact of real-life, 90-days exposure to mixture of toxic metal(oid)s, Cd, Pb, Ni, Cr, As and Hg, on the nuclear factor erythroid 2-related factor 2 and hemoxygenase-1 (Nrf2/HO-1) signalling and redox status by assessing total sulfhydryl groups (SH), glutathione (GSH), superoxide dismutase activity (SOD), malondialdehyde (MDA), and ischemia modified albumin (IMA) in the liver and kidney of Wistar rats. Animals (20 males and 20 females) were randomized in 2 control and 6 treated groups that received by oral gavage mixture of metal(oid)s solutions in doses that reflect blood metal(oid) levels determined in previous human biomonitoring study as benchmark dose (F/M _BMD), median (F/M _MED), and 95th percentile (F/M _95).

Comparison of different ecotoxicological batteries with WOE approach for the environmental quality evaluation of harbour sediments.

This study was conducted under the Italian Ministerial Decree D.M. 173/2016 which regulates the assessment of the Sediment Class Quality in Italy using ecotoxicological bioassay and chemical analysis (Weight-Of-Evidence model).

The impact of the Bagnoli industrial site (Naples, Italy) on sea-bottom environment. Chemical and textural features of sediments and the related response of benthic foraminifera.

The coastal zone of the disused industrial site of Bagnoli, has been studied since 1999 in order to highlight chemical and ecological features of pollution, mainly due to a steel plant. This further study was performed in order to check the foraminiferal response to changes in sediment grain-size and contaminant concentrations and to recognise the actual effects of the environmental stress determined by industrial pollution on the foraminiferal assemblages. This was attained by considering a wider area than in the previous studies so as to recognise the possible reference conditions.

Benthic foraminifera from the coastal zone of Baia (Naples, Italy): assemblage distribution and modification as tools for environmental characterisation.

The coastal zone of Baia (Naples) is currently included in a protected marine area, but in past it was affected by strong anthropogenic pressure for commercial harbour activity. In order to investigate the impact of past activities, a multidisciplinary characterisation was undertaken to evaluate the environmental quality of marine sediments. Thirty-six grab samples were collected for grain-size, heavy metals, PAHs and PCBs analyses.
