Polycyclic Aromatic Hydrocarbon (PAH) pollution in wild Adriatic fish - from the main determining factors of PAH accumulation to some biological responses of fish
Full text linkQuesta tesi si focalizza su 16 idrocarburi policiclici aromatici (IPA), classificati come inquinanti prioritari
dall’Unione Europea (EU) e dall’Agenzia per la Protezione Ambientale degli Stati Uniti (US EPA), per i loro
effetti cancerogeni e mutageni. Inoltre, essi vengono inclusi tra i contaminanti da considerare nei Descrittori
8 e 9 della direttiva quadro sulla Strategia per l’Ambiente Marino (MSFD). Il livello e la distribuzione degli IPA
sono stati investigati nei sedimenti marini e in diversi tessuti di due specie ittiche (Solea solea e Mullus
barbatus) provenienti da un’importante zona di pesca situata nel bacino dell’Adriatico Settentrionale e
Centrale. La presente tesi di dottorato fornisce nuove informazioni dei principali effetti biologici, chimici e
ambientali sul livello di contaminazione da IPA nei tessuti dei pesci, compreso quello edibile. Inoltre, viene
esaminata la relazione tra il livello degli IPA e quello dell’espressione del mRNA di alcuni enzimi antiossidanti,
nonché la perossidazione lipidica. Tale tesi fornisce utili ed innovative informazioni sulla risposta biologica di
pesci selvatici dell’Adriatico, esposti ad inquinamento da IPA. Studi mirati in questa direzione sono essenziali
per determinare lo stato ambientale degli ecosistemi marini e il raggiungimento del buono stato ambientale
(GES), come suggerito dalla MSFD. Pertanto, i risultati di questa tesi sono rilevanti per l’applicazione della
MSFD, e potrebbero essere utilizzati per aumentare e definire il set di dati per lo sviluppo di nuovi indici di
qualità ambientale, nonché per proteggere gli stock ittici dell’Adriatico.This thesis focuses on the 16 polycyclic aromatic hydrocarbons (PAHs), classified as priority pollutants by the
European Union (EU) and the United States Environmental Protection Agency (US EPA) due to their
carcinogenic and mutagenic effects and, included in the Descriptor 8 and 9 of the Marine Strategy Framework
Directive (MSFD). The PAH level and distribution were investigated in different tissues of two fish species
(Solea solea and Mullus barbatus) and in marine sediments of an important fishing ground located in the
Northern and Central Adriatic Sea. The present PhD thesis provides new insight into the main biological,
chemical and environmental effects on the PAH level in fish tissues, including edible tissue. In addition, it
examines the relationship between the PAH levels and mRNA expression level of some antioxidant enzymes,
as well as lipid peroxidation, proving innovative and useful information on the biological responses of wild
Adriatic fish, exposed to PAH pollution. Therefore, pointed studies in this direction are essential to determine
the environmental status of the marine ecosystems and the achievement of the GES, as suggested by MSFD.
Furthermore, the results of the present thesis are relevant for the MSFD application. Particularly, results and
products of this PhD thesis could be used to increase and define the dataset for the development of new
environmental quality indexes, as well as to protect the Adriatic fish stocks

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
