Given the increasing importance of exploring consumers' concerns about the welfare of farmed animals, a survey questionnaire was designed to investigate the role of cognitive styles along with sociodemographic characteristics in consumers' perceptions about nonhuman animal welfare (AW) and their willingness to pay for animal-friendly products. The results revealed that the survey respondents were concerned about AW and had negative perceptions of the way animals were treated. They showed positive attitudes toward some actions to be taken for improving AW and strongly agreed to pay more for animal-friendly products. Consistent with previous studies, results revealed significant associations between sociodemographics and concern toward AW. However, some observed differences were highlighted by cognitive styles rather than by sociodemographic characteristics. These results indicate a significant link between cognitive styles and perceptions and attitudes toward AW, which may outweigh previously found sociodemographic differences and fuel the contemporary debate on AW. © Taylor & Francis.

Phenolics are antioxidants present in tomato fruit that confer healthy benefits and exhibit crucial roles for plant metabolism and response to environmental stimuli. An approach based on two genomics platforms was undertaken to identify candidate genes associated to higher phenolics content in tomato fruit. A comparative transcriptomic analysis between the S. pennellii Introgression Line 7-3, which produced an average higher level of fruit phenolics, and the cultivated variety M82, revealed that their differences are attributed to genes involved in phenolics accumulation into the vacuole. The up-regulation of genes coding for one MATE-transporter, one vacuolar sorting protein and three GSTs supported this hypothesis. The observed balancing effect between two ethylene responsive factors (ERF1 and ERF4) was also hypothesized to drive the transcriptional regulation of these transport genes. In order to confirm such model a TILLING platform was explored. A mutant was isolated harbouring a point mutation in the ERF1 cds that affects the protein sequence and its expected function. Fruits of the mutant exhibited a significant reduced level of phenolics than the control variety. Changes in the expression of genes involved in sequestration of phenolics in vacuole also supported the hypothesized key-role of ERF1 in orchestrating these genes. © 2013 Elsevier Ireland Ltd.

Samples of Mytilus galloprovincialis were examined to investigate the levels of polybrominated diphenyl ethers (PBDEs) in the Apulia's marine environment, a region in the South of Italy. The levels of nine PBDE congeners were measured in 40 mussel samples taken from the aquaculture farms in the South of Adriatic Sea and North Ionian Sea along the Apulia coast. While accelerated solvent extraction (ASE) was the extraction technique adopted using acetone/n-hexane (1:1, v/v), the content of PBDEs was evaluated by using gas chromatography coupled with high-resolution mass spectrometry (GC-HRMS) via electron ionization (EI) in the multiple ion monitoring (MIM) mode (two ions for each compound). The 13C mass-labeled compounds were used to establish the levels of PBDEs in M. galloprovincialis samples. The total concentration of PBDEs (ΣPBDEs) ranged from 0.2 to 6.9 ng/g dry mass, with the highest concentrations found around coastal areas of Salento. With regard to the composition of PBDE congeners, BDE-47, BDE-99 and BDE-100 were the predominant congeners in most of the samples. The present study is the first to report levels of PBDEs occurring in aquatic organisms living in aquaculture farms of Apulia region. Copyright © 2010 John Wiley & Sons, Ltd. Source

We report on the content of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in 15 breast milk samples of nursing women living in the city of Taranto (Southern, Italy) or nearby. Breast milk samples were collected over the 2008-2009 period and analyzed by gas chromatography coupled with high-resolution mass spectrometry (GC-HRMS) upon accelerated solvent extraction (ASE) using acetone/n-hexane mixture 1:1 (v/v). The method was validated demonstrating good performing features. Profiles of PCDD/PCDF congeners in breast milk samples exhibited a prevalence of PCDFs compared to PCDDs. Toxic equivalents (TEQs in picogram per gram fat) of four breast milk were far above the legal limit for human consumption of 3.0 pg/g; their estimated daily and weekly dietary intake were almost 5-20 and 10-40 times higher, respectively, than the tolerable intake values established by the World Health Organization. © 2013 Springer-Verlag Berlin Heidelberg.

A number of water purification processes have been developed in recent years based on the utilisation of low-cost materials with high pollutant removal efficiency. Among these materials, fly ash and zeolite synthesised from fly ash are two examples of high-efficiency adsorbents. Column absorption tests were performed in order to compare the manganese sorption behaviour of an Italian coal fly ash and zeolite synthesised from it. Different masses of both materials (10-60g) were exposed to solutions containing a total metal concentration of 10mg/L. Batch adsorption studies were also conducted to determine the effect of time on the removal on Mn sequestration. The results indicate that both materials are effective for the removal of Mn from aqueous solution by precipitation due to the high pH of the solid/liquid mixtures. However, the leaching tests reveal that the amount of Mn removed from the fly ash was greater than that leached from the zeolite, thereby indicating that the metal is partially sequestrated by zeolite. © 2014 Elsevier Ltd.
