Article
As fossil fuels are depleting day by day, it is necessary to find an alternative fuel to fulfill the energy demand of the world. Biodiesel is considered as an environmentally friendly renewable diesel fuel alternative. The interest in using Jatropha curcas as a feedstock for the production of biodiesel is rapidly growing. On the one hand, J. curcas...
Article
Hourly concentration averages of tropospheric ozone were measured, during the period from January 2007 to December 2007, in a street with a lot of traffic in Las Palmas de Gran Canaria. The values obtained, calculated by maximum daily concentration of every eight hours average, were below the limit value set by the European Union Directive 2008/50...
Article
In the present paper, levels of PM10 in three capitals of the province of Las Palmas (Las Palmas G.C, Arrecife and Puerto del Rosario) from January to December 2007 have been studied. The data were obtained from three urban monitoring sites. Mean annual PM10 concentrations in Las Palmas G.C, Arrecife and Puerto del Rosario reached (30, 7; 33,4 and...
Article
In this work, we quantified the total, water-soluble and insoluble fractions of 12 metallic species (Na, Ca, K, Mg, Fe, Zn, Cr, Ni, Cu, Cd, Pb and Mn) present in total suspended particulates (TSP) in an urban area with heavy traffic (about 80 000 vehicles/day) of Las Palmas de Gran Canaria (Canary Islands). Experimental measurements were made from...
Article
At the presente work levels corresponding to TSP and PM10 fractions of atmospheric particulate matter in Telde (Gran Canaria island) in relation with types of pollution sources in the area and comparing with values in different parts of the world, are presented . Experience was carry out between October 2002 and September 2003. A total of 54 sample...
Article
In this work, 11 metallic species water-soluble presents in particulate matter have been quantified in an urban area with high density of traffic (80,000 vehicles/day). Experimental study was realized between June and December 2002. In total, 42 samples (7 samples / month), were collected. Concentrations levels of total suspended particulates (TSP)...
Article
The size distribution of 14 polycyclic aromatic hydrocarbons (PAHs) present in particulate aerosol in two different areas of the city of Las Palmas de Gran Canaria was investigated in May 2002. One of the study areas (Bravo Murillo) was under the influence of heavy traffic and the other (Pedro Lezcano) under that of small-scale industries of variou...
Article
Concentration levels, seasonal variation and winter/summer ratios of 11 polycyclic aromatic hydrocarbons (PAHs) in the TSP of Las Palmas de Gran Canaria city were determined. The study area is under the influence of heavy traffic (80000 vehicles/day). Pyr/BaA, Pyr/Flt, B(ghi)P/I(cd)P and B(b+k)F/B(ghi)P ratios were calculated; the values of these t...
Article
Airborne concentrations of 8 polycyclic aromatic hydrocarbons (PAHs): fluoranthene, Flt, Pyrene, Pyr, benzo(a)anthracene, BaA, chrysene, Chr, benzo(b)fluoranthene + benzo(k)fluoranthene,B(b + k)F, benzo(a)pyrene, BaP and benzo(g,h,i)perylene, B(ghi)P,were measured in Jinmar, a small town on the island of Gran Canaria (Spain) during a 12 month perio...
Article
This paper presents data on the levels of the elements, sodium, potassium, calcium, magnesium, iron, copper, nickel, lead and the polycyclic aromatic hydrocarbon, benzo(a)pyrene, as constituents of total suspended particulate (TSP) together with the gases SO2 and NOx present in the environmental air of Jinamar, a small town on the island of Gran Ca...
Article
Aerosol mass size distributions of 14 polycyclic aromatic hydrocarbons (PAHs) were measured during 7 days in a zone of Las Palmas de Gran Canaria submitted to intensive car traffic. Mass median diameters range from 0.86 to 1.82 μm for particulate matter and from 0.38 to 1.31 μm for individual PAHs. Particulate matter mass size distribution exhibit...
Article
Aerosol samples in the atmosphere of Jinamar valley have been collected and size-fractionated during 7 days period using five-stage cascade impactor. Aerosol particles were separated into six size fractions. The samples were analyzed for polycyclic aromatic hydrocarbons (PAHs) with molecular weights between 128 and 276, using gas chromatography/mas...
Article
Concentrations of polycyclic aromatic hydrocarbons (PAHs): pyrene chrysene, fluoranthene and benz(a)anthracene in atmospheric particulates in Jinamar(Gran Canaria) during a 12 months period by GC/MD were determinated. Mean concentrations, pyrene (0.040ng/m3), chrysene (0.046 ng/m3), fluoranthene (0.082 ng/m3) and benz(a)anthracene (0.103 ng/m3), re...
Article
Concentrations of polycyclic aromatic hydrocarbons(PAHs) in atmospheric particulates in a suburban zone of Gran Canaria isle during 12 months period by GC/MD were determinated. In this paper the results as well as the influence of some mateorological variables on the concentrations of benzo(a)pyrene, B(a)P, Benzo(ghi)perylene, B(ghi)P and Benzo(b+k...
Article
Atmospheric deposition of metallic elements was measured, using a conventional dry collector, from May 1993 to May 1995 at four sites on Las Palmas G.C. Analytical method was Absortion Atomic Spectroscopy. Averaging results from four sites, the following deposition rates were obtained for Las Palmas G.C. in μg/m2 · d: Na 1.21 · 104; K 1.24 · 103; C...
Article
Polycyclic aromatic hydrocarbons (PAHs) are by-products of incomplete combustion or pyrolysis of organic matter common processes in many natural transformations or human activities. These hydrocarbons are frequent pollutants in air, soil and water. The risk factor on living beings of the PAHs issued to the atmosphere is measured in relationship to...
Article
At this work we present a physicochemical study about Las Palmas aerosol, using filter samples collected from five stages cascade impactors, covering particle diameter between 10 and 0.01 μm. The bimodality of mass distribution, with maxima near 0.31 μm for fine particles (anthropogenic aerosol) and 4.9 μm (natural aerosol) for coarse, and the dist...
Article
The study of meteorological fluctuations that have been reported in urban and semiurban zones has reached in the last years an increasing importance to environmental pollution researches because its knowledge permits the elaboration of empirical models able to predict periods of potential pollution in these zones. In this work, it has been made use...
