Many countries, including Mexico, are facing a largely unrecognized epidemic of low-level lead poisoning. Mexico is the sixth largest lead-producing country in the world, and 40% of its production is used locally in different industrial processes that cause lead contamination of the environment. The major sources and pathways of lead exposure among the(More)
A wide range of human pharmaceuticals are present at low concentrations in freshwater systems, particularly in sections of polluted river. These compounds show high biological activity, often associated with a high stability. These characteristics imply a potential impact of these substances on aquatic biota even when present at low environmental(More)
This review examines information generated over the past decade on the pollution of rivers in regions with a mediterranean-type climate (med-climate). Pollution has clearly increased in the last 100 years and is correlated with the development of industry, agriculture and human population. Important efforts have been made in some med-climate countries in(More)
Water scarcity is a serious environmental problem in many European regions, and will likely increase in the near future as a consequence of increased abstraction and climate change. Water scarcity exacerbates the effects of multiple stressors, and thus results in decreased water quality. It impacts river ecosystems, threatens the services they provide, and(More)
As a result of climate change, streams are warming and their runoff has been decreasing in most temperate areas. These changes can affect consumers directly by increasing their metabolic rates and modifying their physiology and indirectly by changing the quality of the resources on which organisms depend. In this study, a common stream detritivore(More)
The presentation of scalp metastases from leiomyosarcoma of the vena cava is an extremely infrequent event. There are no other publications that describe such finding and very few of leiomyosarcoma in vessels. About this event we have reviewed the English literature describing studies on scalp metastases and skin metastases in general: their incidence,(More)
Mediterranean rivers are hotspots for biodiversity, and riverine species are adapted to regular physical perturbations that affect channel morphology during flashy rainfall-runoff events. Dams alter flow regimes, changing flood magnitude and frequency; they also interrupt the continuity of sediment transport. Changes in both flood and sediment transport(More)
Most fluvial networks worldwide include watercourses that recurrently cease to flow and run dry. The spatial and temporal extent of the dry phase of these temporary watercourses is increasing as a result of global change. Yet, current estimates of carbon emissions from fluvial networks do not consider temporary watercourses when they are dry. We(More)
We studied biochemical changes in biofilm and suspended particulate and dissolved organic matter (OM) during the leaf emergence period (March–May 2008) in a forested headwater stream in response to a long-term (4 years, 2004–2008) experimental nutrient enrichment study. This study compared results from one reach upstream of the enrichment point and one(More)
RATIONALE, AIMS AND OBJECTIVES The prenatal education promotes the empowerment of parents during pregnancy and postnatal period. This study aimed to assess the quality of educational sessions held in the third trimester of pregnancy as part of the parenting education programme for Spanish National Health System in Madrid. METHODS The design is a(More)
