Abstract

The aim of this work was to investigate the mutagenetic effects of the exposure to Radon-222 and its progeny in laboratory mice. In order to realize this objective, a study was carried out in two small towns, where Radon pollution is notoriously present. Six-week-old CDI female mice, placed in cages, were located in the underground of three buildings in Ciampino (Rome) and in a cellar in Vetralla (Viterbo). They were exposed to natural emissions of Radon for 30 days. Radon-222 activity was measured both on a continuous basis using AWARE Corporation (U.S.A.) electronic detectors, and every 10 days using CR-39 closed detectors (U-series SrI., Italy). The micronucleus test, a sensitive mutagenicity test in vivo, was applied to the peripheral blood of mice before exposure, and 10, 20, and 30 days after. Micronucleated erythrocyte frequencies were determined counting 2000 erythrocytes per animal. The results showed that in mice groups exposed to more than 700 kBqh-1/m³ of Radon-222, the micronuclei frequency was significantly higher than that observed before exposure. A significant correlation between micronuclei induction and increase of Radon exposure was observed. These preliminary results suggest that further investigation of the mutagenic properties of Radon and its progeny has to be carried out in order to establish a possible relationship with carcinogenesis.

Abstract

Are useful tools to study many aspects of teleost life in marine environment. In order to identify cellular markers to investigate pollution, the effect of different concentrations of organic mercury (CH 3HgCl) on the morphology and responses of Mytilus galloprovincialis haemocytes was studied in this work. To investigate the effectiveness of a combined slurry-ice/ozone system (SIO) on prolonging the shelf life of two fishery species, i.e. sardines (Sardina pilchardus) and anchovies (Engraulis encrasicolus), a multidisciplinary approach was used.

Abstract

This study aimed to produce new value-added products from dolphinfish (Coryphaena hippurus) as fillets when using cold smoking combined with natural antioxidants, obtained from Halocnemum strobilaceum a plant belonging to halophytes. The fillet treatments were controlled (untreated), immersed in standard brine (STD), treated with NaCI and antioxidant before freezing (Aox-pre) and treated with NaCl and antioxidant after thawing (Aox-post). The quality of dolphinfish fillets was assessed using sensory, biochemical, microbiological, and technological parameters. Treating fillets with antioxidants before freezing and cold smoking (Aox-pre) enhanced significantly the shelf life, as well as improved the biochemical, microbiological, and sensory aspects of the product. Aox-pre fillets had the lowest peroxide values (PV) and malondialdehyde (MDA) content, demonstrating that the immediate treatment of fillets with the polyphenols protected lipids from peroxidation. The smoking process, together with antioxidant treatment, significantly reduced microbial counts after 15 days of storage, compared to the control. Overall, combining antioxidant treatments with cold smoking has a positive effect on the quality of Aox-pre fillets with respect to both sensory components and biochemical parameters associated with shelf life. Consequently, Aox-pre treatment enhances the marketability of this species, promoting local and seasonal products, contributing to costal fisheries sustainability. © 2019 The Authors.
