Informe lexislativo : regulación das adaptacións do currículo nas ensinanzas de réxime xeral : orden do 6 de outubro de 1995 (DOG, 07-11-95). 'Informe legislativo : regulación de las adaptaciones del currículo a las enseñanzas de régimen general : orden del 6 de octubre de 1995 (DOG, 07-11-95)'.

Análisis de la Orden que regula las adaptaciones curriculares en la Enseñanza Secundaria gallega (Orden del 6 de octubre de 1995, DOG 7 noviembre de 1995). Aunque esta norma ha sido modificada por otras disposiciones en 2002 y 2004, sigue siendo el marco básico de referencia. Su análisis permite deslindar las responsabilidades de cada uno de los profesionales que intervienen en la creación, proceso y revisión de las adaptaciones curriculares. El análisis se expresa en forma de diagramas.

Distribution and mobility of trace elements in soils and vegetation around the mining and smelting areas of Tharsis, Riotinto and Huelva, Iberian Pyrite Belt, SW Spain

Trace elements may present an environmental hazard in the vicinity of mining and smelting activities. However, the factors controlling their distribution and transfer within the soil and vegetation systems are not always well defined. Total concentrations of up to 15,195 mg center dot kg (-1) As, 6,690 mg center dot kg(-1) Cu, 24,820 mg center dot kg(-1) Pb and 9,810 mg center dot kg(-1) Zn in soils, and 62 mg center dot kg(-1) As, 1,765 mg center dot kg(-1) Cu, 280 mg center dot kg(-1) Pb and 3,460 mg center dot kg (-1) Zn in vegetation were measured. However, unusually for smelters and mines of a similar size, the elevated trace element concentrations in soils were found to be restricted to the immediate vicinity of the mines and smelters (maximum 2-3 km). Parent material, prevailing wind direction, and soil physical and chemical characteristics were found to correlate poorly with the restricted trace element distributions in soils. Hypotheses are given for this unusual distribution: (1) the contaminated soils were removed by erosion or (2) mines and smelters released large heavy particles that could not have been transported long distances. Analyses of the accumulation of trace elements in vegetation (median ratios: As 0.06, Cu 0.19, Pb 0.54 and Zn 1.07) and the percentage of total trace elements being DTPA extractable in soils (median percentages: As 0.06%, Cu 15%, Pb 7% and Zn 4%) indicated higher relative trace element mobility in soils with low total concentrations than in soils with elevated concentrations.
