The impact of abandoned/disused marble quarries on avifauna in the anticline of Estremoz, Portugal: does quarrying add to landscape biodiversity?

Although the extractive operations of quarrying are often considered environmental threats, there is some evidence that abandoned quarries may have a significant positive impact on biodiversity by enhancing habitat quality for several species. In Estremoz Anticlinal, SE Portugal, many of the existing marble quarries have been inactive for decades and were abandoned without any restoration project in progress. The impact of quarry abandonment on avifauna diversity was assessed relative to reference conditions using adjacent rural fields as control areas. No significant differences were found in within-community diversity (alpha diversity) between abandoned quarries and reference sites. However, several dissimilarity indices showed a clear divergence in species composition between abandoned quarries and reference sites. Furthermore, statistically significant differences in species compositions were found between quarries abandoned for different periods. Over time, species composition becomes more similar to that observed in reference sites, reflecting ecological succession and landscape resilience to quarrying. Nevertheless, the studied quarrying landscape exhibited higher gamma and beta diversity than the former traditional landscape; thus, our results suggest that abandoned quarries, rather than damaging and destroying niches, can promote new ecological niches and significantly diversify rural landscapes.

Quantitative Analysis of Fault and Fracture Systems and their Impact on Groundwater Flow in Irish Bedrock Aquifers

Fault and fracture systems are the most important store and pathway for groundwater in Ireland’s bedrock aquifers, either directly as conductive flow structures, or indirectly as the locus for the development of dolomitised limestone and karst. This article presents the preliminary results of a study involving the quantitative analysis of fault and fracture systems in the broad range of Irish bedrock types and a consideration of their impact on groundwater flow. The principal aims of the project are to develop generic conceptual models for different fault/fracture systems in different lithologies and at different depths, and to link them to observed groundwater behaviour. Here we briefly describe the geometrical characteristics of the main post-Devonian fault/fracture systems controlling groundwater flow from field observations at outcrops, quarries and mines. The structures range from Lower Carboniferous normal faults through to Variscan-related faults and veins, with the most recent structures including Tertiary strike-slip faults and ubiquitous uplift-related joint systems. The geometrical characteristics of different fault/fracture systems combined with observations of groundwater behaviour in both quarry and mine localities, can be linked to general flow and transport conceptualisations of Irish fractured bedrock. Most importantly they also provide a basis for relating groundwater flow to particular fault/fracture systems and their expression with depth and within different lithological sequences, as well as their regional variability.

New age estimates for the Palaeolithic assemblages and Pleistocene succession of Casablanca, Morocco

Marine and aeolian Quaternary sediments from Casablanca, Morocco were dated using the optically stimulated luminescence (OSL) signal of quartz grains. These sediments form part of an extensive succession spanning the Pleistocene, and contain a rich faunal and archaeological record, including an Acheulian lithic assemblage from before the Brunhes–Matayama boundary, and a Homo erectus jaw from younger cave deposits. Sediment samples from the sites of Reddad Ben Ali, Oulad J’mel, Sidi Abderhamane and Thomas Quarries have been dated, in order to assess the upper limits of OSL. The revision of previously measured mammalian tooth enamel electron spin resonance (ESR) dates from the Grotte des Rhinocéros, Oulad Hamida Quarry 1, incorporating updated environmental dose rate measurements and attenuation calculations, also provide chronological constraint for the archaeological material preserved at Thomas Quarries. Several OSL age estimates extend back to around 500,000 years, with a single sample providing an OSL age close to 1 Ma in magnetically reversed sediments. These luminescence dates are some of the oldest determined, and their reliability is assessed using both internal criteria based on stratigraphic consistency, and external lithostratigraphic, morphostratigraphic and independent chronological constraints. For most samples, good internal agreement is observed using single aliquot regenerative-dose OSL measurements, while multiple aliquot additive-dose measurements generally have poorer resolution and consistency. Novel slow-component and component-resolved OSL approaches applied to four samples provide significantly enhanced dating precision, and an examination of the degree of signal zeroing at deposition. A comparison of the OSL age estimates with the updated ESR dates and one U-series date demonstrate that this method has great potential for providing reliable age estimates for sediments of this antiquity. We consider the cause of some slight age inversion observed at Thomas Quarries, and provide recommendations for further luminescence dating within this succession.

Levels, sources and seasonality of coarse particles (PM10-PM2.5) in three European capitals e implications for particulate pollution control

Coarse particles of aerodynamic diameter between 2.5 and 10 mm (PMc) are produced by a range of natural (windblown dust and sea sprays) and anthropogenic processes (non-exhaust vehicle emissions, industrial, agriculture, construction and quarrying activities). Although current ambient air quality regulations focus on PM2.5 and PM10, coarse particles are of interest from a public health point of view as they have been associated with certain mortality and morbidity outcomes. In this paper, an analysis of coarse particle levels in three European capitals (London, Madrid and Athens) is presented and discussed. For all three cities we analysed data from both traffic and urban background monitoring sites. The results showed that the levels of coarse particles present significant seasonal, weekly and daily variability. Their wind driven and non-wind driven resuspension as well as their roadside increment due to traffic were estimated. Both the local meteorological conditions and the air mass history indicating long-range atmospheric transport of particles of natural origin are significant parameters that influence the levels of coarse particles in the three cities especially during episodic events.

South & West Cumberland Fisheries Advisory Committee 17th October, 1977

This is the report from the South & West Cumberland Fisheries Advisory Committee meeting, which was held on the 17th October, 1977. It covers fisheries income and expenditure, licence duties, and information on the River Marron at Lostrigg Beck in connection with opencast coal workings in the area. It also looks at the proposal for the development of the Eskett Quarries and the likely effect on the River Ehen, and the possible development of Rivers Waver and Wampool as a sea trout fishery. The report for that covers the physical descriptions of the catchments, abstractions, discharges, biological aspects, chemical aspects and the present situation regarding fisheries. Also included is the report by the area fisheries officer on fisheries activities which includes information on river improvement works on the River Calder, Branthwaite Weir Fish Pass, a fish kill on the tributary of the River Calder, stock numbers, and an update on Holmwrangle hatchery. The Fisheries Advisory Committee was part of the Regional Water Authorities, in this case the North West Water Authority. This preceded the Environment Agency which came into existence in 1996.

Building with Scottish Stone.

Building with Scottish Stone aims to encourage more use of stone sourced from Scotland’s working quarries and to provide a better understanding of those mineralogical properties which give each stone its distinctive quality. The nation’s architectural history is synonymous with the use of natural stone, and the principles of construction developed over generations in response to Scotland’s particular climatic conditions still find relevance today in the design and detailing of new buildings. Equally, an understanding of the ways in which stone is extracted and processed is as fundamental to its contemporary use as having up-to-date knowledge of the continuously changing legislation that affects its specification and procurement. Building with Scottish Stone is a stimulating introduction to these and many other factors to be considered when using this richly-varied and timeless resource in the design of new buildings.

Medidas de intervención para promoción de conductas saludables y prevención de riesgos laborales relacionados con accidentalidad y enfermedad laboral en trabajadores de minas de Carbón

Colombia en su legislación normatiza el sector de la minería de carbón, sin embargo se considera que las estrategias no han sido suficientes para la identificación, prevención y control de la accidentalidad y enfermedad laboral. Durante el año 2013 el índice de fatalidad fue de 1,59. Estadísticas del año 2004 evidencian que las neumoconiosis fueron las mayores causas de invalidez de origen profesional. Objetivo: Categorizar actividades de intervención en promoción y prevención de accidentalidad y enfermedad laboral en trabajadores de la minería de carbón. Metodología: Se realizó una revisión de literatura sobre minería de carbón y salud la cual fue obtenida de las bases de datos PUBMED, Sciendirect, VHL, SINAB por literatura publicada sin límites de año, en idioma inglés, español o portugués. Para la búsqueda se utilizaron términos en lenguaje controlado (términos MESH), revisión por pares de títulos y resúmenes. Las publicaciones fueron seleccionadas para revisión de texto completo bajo criterios de inclusión y exclusión. Los códigos contemplados para esta revisión fueron: a) país donde la intervención se llevó a cabo, b) salud ocupacional, c) prevención de accidentalidad, d) programas de promoción, e) tecnologías, f) resultados obtenidos. Resultados: Del total de 2500 artículos seleccionados por los autores principales se realizó la revisión de los primeros 300 artículos, 32 hacen referencia al tema de salud ocupacional y minería de carbón, 10 contienen intervenciones consideradas de relevancia para esta revisión bibliográfica. Se presentan intervenciones estadísticamente significativas (p<0.05) y que han demostrado ser de impacto positivo en la minería de carbón en promoción y prevención de accidentalidad y enfermedad ocupacional. Conclusiones: Se identificaron las siguientes cuatro tipos de intervención: 1) las de carácter educativo que hacen referencia a las capacitaciones participativas, el entrenamiento por medio de “degraded image”, la realización de gestión de autocontrol y retroalimentación para el uso de elementos de protección personal (EPP), la aplicación del Modelo de Proceso Paralelo Extendido; 2) intervenciones preventivas como la medición de alcoholimetría antes del turno, la presencia de personal de enfermería en minas de carbón y el reconocimiento de los predictores de la enfermedad para optimizar la prevención primaria; 3)intervenciones de vigilancia como la promovida en la metodología Estadísticas Europeas de Accidentes de Trabajo (EEAT) para la investigación de los accidentes de trabajo, la aplicación de las recomendaciones de la Organización Mundial de la Salud (OMS) para la detección de la neumoconiosis y 4) De carácter tecnológico consistente en la intervención de tareas a partir de los resultados de la aplicación del software desarrollado por el Instituto Nacional para la Seguridad y Salud Ocupacional (NIOSH). Estas intervenciones han demostrado ser eficaces en la promoción y prevención de accidentalidad y enfermedad ocupacional por lo cual se recomienda su aplicación en Colombia posterior al análisis de costo-efectividad.
