Improving the solid-phase extraction of “quat” pesticides from water samples
1998
A novel strategy, based on the addition of a cationic surfactant, for preventing the interferences associated with a diminution in the efficacy of solid-phase extraction (SPE) with silica cartridges of diquat, paraquat and difenzoquat in water is developed. Conditions for extraction are optimised with respect to pH, cationic surfactant and its concentration. Humic acids, anionic surfactants, inorganic salts and other organic contaminants like pesticides, phenols, polycyclic aromatic hydrocarbons and polychlorinated biphenyls produce the studied interferences. The best performance is shown in the improvement of the "quats" recovery from waters with high levels of humic acids and anionic surf…
Evaluation of 10 pesticide residues in oranges and tangerines from Valencia (Spain)
2006
Abstract One hundred and sixteen orange and tangerine samples from an agricultural cooperative of the Valencian Community (Spain) were analyzed for bitertanol, carbendazim, hexythiazox, imazalil, imidacloprid, methidathion, methiocarb, pyriproxyfen, thiabendazole, and trichlorfon by liquid chromatography–mass spectrometry (LC–MS) after a conventional multiresidue extraction procedure. Of 52 samples that contained pesticide residues, carbendazim was detected in 27 (51.9%) in the concentration range of 0.02–0.04 mg kg−1, hexythiazox in 22 (42.3%) in the concentration range of 0.02–0.05 mg kg−1, imazalil in 8 (15.0%) in the concentration range of 0.02–1.2 mg kg−1, imidacloprid in 5 (9.6%) in a…
Determination of macrolide and lincosamide antibiotics by pressurised liquid extraction and liquid chromatography-tandem mass spectrometry in meat an…
2010
Abstract A total of 155 samples, including meat and milk, were analyzed using a method developed for determining five macrolide antibiotics: tilmicosin (TILM), tylosin (TS), spiramycin (SPM), erythromycin (ERY), and tulathromycin (TULA) and two lincosamide antibiotics: pirlimycin (PIRL) and lincomycin (LM). The method was performed by pressurised liquid extraction (PLE) coupled to LC–MS/MS using electrospray ionization in positive ion mode. 2.5 mL of milk or 2.5 g of meat were dispersed in ethylenediaminetetraacetic acid sodium salt 2-hydrate (EDTA) and sea sand. The PLE conditions as: solvent, temperature, pressure, static time, and cell size were optimized. The following analytical parame…

Pesticide residues in oranges from Valencia (Spain)
2001
One hundred and fifty citrus samples from an agricultural co-operative of the Valencian Community (Spain) were analysed for pre- and post-harvest pesticide residues using high performance liquid chromatography and gas chromatography. Among the residues from post-harvest treatments, imazalil was detected in 112 (74.7%) samples at a mean level of 1.2 mg/kg, thiabendazole in 21 (14.0%) samples at a mean level of 0.47 mg/kg and carbendazim in 5 (3.3%) samples at a mean level of 1.05 mg/kg. Among the residues from pre-harvest treatment, dicofol was detected in 28 (18.7%) samples at a mean level of .28 mg/kg chlorpyriphos in 19 (12.7% samples at a mean level of 0.16 mg/kg and endosulfan in 11 (7.…
Ridisegnare il confine fra "noi" e "loro": interrogativi sulla revoca della cittadinaza
2019
Esiste un limite costituzionale alla privazione della cittadinanza? Il decreto legge n. 113/2018 ha recentemente introdotto un nuovo articolo 10-bis nella legge n. 91/1992 che disciplina la revoca della cittadinanza. Si tratta di una “sanzione” che può essere inflitta dal Presidente della Repubblica su proposta del Ministro dell’interno entro tre anni dalla condanna definitiva per gravi fatti di reato ed è applicabile soltanto ad alcune categorie di cittadini (non si può revocare la cittadinanza ai cittadini iure sanguinis, per beneficio di legge o per adozione). La revoca della cittadinanza è una assoluta novità nella legislazione italiana a far data dalle leggi fasciste del 1926 e sembra …
Towards Next Generation System Architecture for Emergency Services
2011
European Union has decided that all emergencies can be reported to authorities by European citizens by calling 112 or sending a text message to 112. Distributing warnings and alerts of authorities to citizens currently happens through national TV and radio channels, but telecom networks are also used now in some countries for this purpose. During the last ten years there have been attempts to develop new system architectures for various emergency service provision phases. Some of them are already deployed in special cases, like in ambulance services. Multimedia emergency alert messages can be delivered to citizens over fixed and mobile telecom networks and commercial systems are already in …
Sabiedrisko organizāciju loma Turcijas pievienošanās procesā ES.
2016
"Pilsoniskās sabiedrības organizācijas" ir vienas no būtiskākajiem spēlētājiem pēdējā laika sarunu procesos ar Turciju un ES. Eiropas Savienība pievērš lielu uzmanību tam, lai veidotu kontaktu un sadarbotos ar pilsoniskās sabiedrības organizācijām kandidātvalstīs. Šajā kontekstā Turcija, kā kandidātvalsts, cenšas turpināt šo procesu pilsoniskās sabiedrības dialoga ietvaros, kas pirms tam ir ticis palēnināts politiskās situācijas dēļ, lai gan Turcijas ES kandidatūra ir kalpojusi par kritisku izvērtējumu Turcijas PSO vēsturiskajam insitucionālismam. Vēl jo vairāk, ES Eiropas Komisijas ģenerālsekretārs un Eiropas Komisijas delegācija Turcijā cenšas paātrināt procesu ar daudzveidīgiem projektie…
Civil Society in the 2004 Romanian Elections: Watchdog, Involved Arbiter or Political Actor?
2010
Abstract Civil society has proven outstanding capacities of involvement in the 2004 general elections in Romania and put a remarkable pressure on the political society. This paper aims to discuss the consequences of such involvement for both the political and civil society. We also investigate the conditions that have favoured a successful challenge of the main political actors by the most visible civic advocacy organizations. Further, we inquire how deep can an actor from the civil society go into the lands of the political society. In the end, we weight the achievements and the failures of civil society’s active involvement in the game of elections.
Spain: commercialization drives public debate and precaution
2000
Since the commercialization of genetically modified (GM) crops and foods in Spain in 1996, these products have become a topic of public concern and conflict. Several important social protagonists from science, industry and civil society have become involved in the public debate. The conflicts have influenced the regulation, improving its precautionary content, in response to social pressures in Spain and elsewhere in Europe. As Spain has become the primary cultivator of GM crops in the European Union, commercial cultivation there has been scientifically monitored for possible long-term environmental effects. Regulators have also asked industry to cease using antibiotic-resistant marker gene…
