Abstract A knowledge of the total amount trace metals is not enough to assess environmental impact polluted soils. For this reason, determination metal species in solution important evaluate their behavior environment and mobilization capacity. Soils contaminated by Cu, Pb, Cd, Zn found at Doñana National Park (Spain) were examined for content. Sequential extraction schemes used determine degree pollution partition elements The three areas studied (marshes, stabilized sand, mine) have...
Median concentration of total PBDEs in maternal serum, paternal umbilical cord and breast milk samples were 12, 17, 6.1 ng/g lipid weight (lw) Vallecas 9.7, 15, 5.5 lw Getafe. The median value found placentas was 1.9 (in Vallecas). BDE 47 the predominant congener serum (maternal, paternal, cord), while 209 placenta samples. BDEs 196 197 detected most results show that PBDEs, like other POPs, can cross barrier, although speed process seems to differ for each PBDE congeners. concentrations...
Concentrations of PCBs, PCDDs, and PCDFs, heavy metals (Cu, Cd, Zn, Pb, Hg), arsenic have been determined in a great variety food samples purchased different markets across the city Huelva, located southwestern Spain under strong industrial activity. All analyzed presented concentrations below maximum allowed by European Community regarding PCDD/Fs, with exception within meat group. An estimation daily intake resulted 1.15 pg WHOPCDD/Fs-TEQ/kg body weight/day for 70 kg person 2.63 WHO-TEQ/kg...
The reactions between fifteen carbonyl oxides and water have been investigated with the aim of contributing to a better understanding effects substituents in reactivity oxides. We employed density functional theory large scale ab initio methods (CCSD(T), CASSCF, CASPT2), combined transition state theory, investigate addition oxide and, for those having methyl substituent syn, hydrogen transfer from group terminal oxygen oxide. In this case, acts as catalyst reaction can contribute...
We studied the importance of smooth vascular muscle endothelium in vasodilator action decoction olive (Olea europaea) leaf. The caused relaxation isolated rat aorta preparations both presence (IC50 1.12 ± 0.33 mg/ml) and absence 1.67 0.16 endothelium. results indicate that relaxant activity lyophilized is independent integrity also showed oleuropeoside a component responsible for but, from results, it seems likely at least one other principle to be found leaf which either itself or else...
In Spain, few studies have evaluated prenatal exposure to heavy metals. The objective of this study was describe lead, mercury and cadmium concentrations in blood from a sample newborn-mother-father trios, as well investigate the association between metals cord parental variables. We also explored relationship metal child characteristics at birth.Metal correlations among family members were assessed using Spearman Rank Correlation Coefficient. Linear regression used explore variables...
Concentrations of 15 BDEs flame retardants have been determined in a large variety food samples purchased different markets across Spain. This is the first time that 184, 191, 196, and 197; impurities from formulations; and/or degradation products BDE 209, detected foodstuffs. Values ranged <0.01 to 2482 pg/g fresh weight. The highest total concentrations were found fish (median 189, range 24−880 f.w.), followed by oils 119, 14.8−2958 meats 75.9, 6.82−2518 shellfish 75.7, 3.29−677 eggs 73.5,...
The analysis of brominated flame retardants (BFRs) commonly relies on the use gas chromatography coupled to mass spectrometry (GC-MS) operating in electron ionization (EI) and capture negative (ECNI) modes using quadrupole, triple ion trap, magnetic sector analyzers. However, these contaminants are examples compounds for which a soft robust technique might be favorable since they show high fragmentation EI low specificity ECNI. In addition, limits quantification (0.01 ng/g) required by...
Abstract Background Data of telemonitoring costs in inflammatory bowel disease (IBD) are scarce and restricted to a few centres. We evaluated healthcare indirect IBD compared standard care after 52 weeks on nationwide scale. Methods A 2-arm randomized multicenter study was performed 24 Spanish centers. included adult patients with who initiated therapy immunosuppressant or biological agents. Patients ileorectal/ileo-pouch anal anastomosis, stoma, active perianal no Internet access were...
With the objective to understand how pattern and degree of chlorination influence on properties title molecules, a computational study biphenyl all chlorinated biphenyls (from 1 10 chlorine atoms, 209 congeners) has been undertaken. The includes conformational searches (and further refinement by molecular dynamics simulations) ab initio calculation electrostatic potential (MEP) dipole moments for congeners. most significant property is MEP, finding good correlation between MEPs substitution...
