Abstract  

Aerosols samples in near-surface air of Granada (Spain) were collected on a weekly basis. The seasonal 210Pb and 7Be concentrations were determined during the five-year period, from October 1993 to September 1997. The elements, despite their different origin and their different distribution throughout the atmosphere, present the same seasonal variation. There was a tendency for a maximum during the summer season and a minimum during fall and/or winter. In this work, the concentration of 7Be and 210Pb and meteorological data have been used in order to determine the periods of the potential radioactive pollution. This study, also, shows that the deposition of 7Be occurs primarily by precipitation except during the investigation periods where precipitation was scarce and irregular.

Abstract  

The uranium concentration and the234U/238U,235U/238U activity ratios were studied in water samples from Jucar River, using low-level -spectrometry. The effects of pH, temperature and salinity were considered and more detailed sampling was done in the neighbourhood of Cofrentes Nuclear Plant (Valencia, Spain). Changes were observed in the uranium concentration with the salinity and the234U/238U activity ratio was found to vary with pH. Leaching and dilution, which depend on pH and salinity, are the probable mechanisms for these changes in the concentration of uranium and the activity ratios.

Abstract  

With the object of quantifying the radiological impact that the Almaraz Nuclear Power Station, situated beside the Tajo river in Spain, induces on its ecosystem, since 1986 we have been carrying out multiple gamma-spectrometric studies and determinations of90Sr concentrations on the receptor media: surface waters, sediments, fishes, aerosols, and soils, in the two likeliest critical transmission pathways of transmission of the radioactive contamination. The principal results are summarized in the present work, and they allow the impact to be quantified, as well as the most probable source to be assigned for each of the levels detected.

Abstract  

The primary aim of this paper is to assess the contribution to the international literature of Spanish scientific production in the research stream of innovation and technology management. For this purpose 72 articles published in the last decade in the most prestigious international journals in this research stream have been evaluated. From this analysis we have concluded that there has been a positive evolution from 1995 to the present time, as much from a qualitative as from a quantitative point of view. Likewise, we have found that research in this research stream is concentrated fundamentally on a reduced group of universities. Nevertheless, these do not focus exclusively on one or a few research subjects, but on a wide range thereof.

Abstract  

Almost all studies on the radioactive content of mushrooms have been centered on 137Cs and, to a lesser extent, on 40K. Other alpha and beta emitters have not been fully investigated and, therefore, their contribution to the dose due to consumption of mushrooms is not taken into consideration. We have studied the incorporation of several radionuclides: into mushrooms using two approaches — laboratory and natural conditions. Pleurotus eryngii was cultured under controlled laboratory conditions, and was found that 134Cs was incorporated to a greater extent in the mushroom than the rest of radionuclides, and 239Pu at least. These results were confirmed by the uptake under natural conditions: 137Cs > 228,230,232Th 234,238U 90Sr >> 239+240Pu. The contribution of thorium and uranium to the dose due to mushroom consumption in Spain is of the same order of magnitude as that of 137Cs.

Abstract  

We set out to analyse and quantify the papers published (for an international readership) by Spanish universities in the field of Legal and Forensic Medicine. For this, we used the MEDLINE data base, to analyse research articles in which a Spanish university teacher (whose sole employment was with a university, as registered by the Ministry of Education in July 2005, (n = 67), appeared as author or co-author in this field. The years covered are 1952 (First year that a Spanish author appears for an article on Legal and Forensic Medicine in this service) to July 2005. A total of 770 articles were counted; the productivity in this area was increasing substantially from the 1980’s onwards. English language scientific journals were the preferred channel of communication. Slightly more than 85% of the works can be classified into four themes, of which Genetics is the most prolific. The number of papers published in English journals represented 84% of the total and only 13% was published in Spanish journals. There was a close relationship between growth in the authority index and inter-institutional co-operation, which boosted the production of articles. When at least one of the authorship of a published paper was a Spanish university teacher, the research was led by a university in 62.4% of cases, and of this 85.6% were Spanish universities.

Abstract  

The studied marsh area is located at the southwest of Spain in an estuarine system formed by the confluence of the Odiel river and the Atlantic ocean. 23 samples collected in the marsh have been analysed by Thick Target Proton Induced X-ray Emission using 2 MeV protons from the 3 MV Van de Graaff accelerator of the ITN. Elemental concentrations in the samples are affected by the Atlantic ocean, the materials transported by the Odiel river and the wastes discharged by the factories of a nearby industrial area. The study has shown that certain areas of the estuary present high concentrations of P, Cu, Zn, As and Pb, which were attributed to the operation of a phosphate fertilizer factory and a Cu extraction factory. The mining activity carried out near the source of the river could be also responsible of part of this contamination. Finally, the spatial distribution of the contamination has reflected the dinamic of the Odiel river waters, due to tidal movements, into the marsh area.

Abstract  

A study is presented on the distribution of thorium and radium isotopes in sediments, suspended matter and water collected along Jucar river (East of Spain), using low-level α-spectrometry. The first aim of this work is to study the thorium and radium activity in water, sediment and suspended matter and their dependence on pH, temperature, conductivity and sediment sizes along Jucar river. The analysis of activity variation with these parameters will provide information about the dynamics of these radionuclides in rivers. The values obtained for the distribution factors between suspended matter and water (K d ) are also discussed.

Allergic conditions are prevalent equine diseases that can be diagnosed by clinical examination alone, but definitive diagnosis is more likely with laboratory testing. The ELISA Allercept© test was used to analyse the serum samples of 73 horses with allergic diseases. Sixty-one horses (83.5%) had allergen-specific IgE levels ≥ 150 ELISA Units (EU), the cut-off defined by the assay. Fifty-four horses had allergic dermatitis (AD) with high IgE levels to Tyrophagus putrescentiae (51.9%), Rumex crispus (48.1%), Tabanus (46.3%) and Dermatophagoides farinae/ D. pteronyssinus (40.7%). Seven horses with recurrent airway obstruction (RAO) had a high prevalence of T. putrescentiae (85.7%), followed by that of Acarus siro (57.1%) and D. farinae/D. pteronyssinus (57.1%). Horses affected with RAO had more positive reactions to mites (2.22 ± 0.84) than did horses with AD (1.51 ± 0.61, P < 0.05). A strong correlation of serum allergen-specific IgE level was found between Culex tarsalis and Stomoxys (r = 0.943) and between Dactylis glomerata and both Secale cereale (r = 0.79) and R. crispus (r = 0.696). These results indicate that among horses with allergic diseases in Spain, ELISA tests demonstrated a high prevalence of serum allergen-specific IgE in response to mites. Our study emphasises the importance of laboratory testing and updating allergy panels to improve the likelihood of a definitive diagnosis and the identification of allergens that should be included in allergic disease treatment.
