Background, aim, and scope
Pharmaceuticals are emerging pollutants widely used in everyday urban activities which can be detected in surface, ground, and drinking waters. Their presence is derived from consumption of medicines, disposal of expired medications, release of treated and untreated urban effluents, and from the pharmaceutical industry. Their growing use has become an alarming environmental problem which potentially will become dangerous in the future. However, there is still a lack of knowledge about long-term effects in non-target organisms as well as for human health. Toxicity testing has indicated a relatively low acute toxicity to fish species, but no information is available on possible sublethal effects. This study provides data on the physiological pathways involved in the exposure of Atlantic salmon as representative test species to three pharmaceutical compounds found in ground, surface, and drinking waters based on the evaluation of the xenobiotic-induced impairment resulting in the activation and silencing of specific genes. 相似文献562.

Purpose
Besides classical organic pollutants and pesticides, pharmaceuticals and their residues have nowadays become recognized as relevant environmental contaminants. The risks of these chemicals for aquatic ecosystems are well known, but information about the pharmaca-plant interactions and metabolic pathways is scarce. Therefore, we investigate the process of uptake of acetaminophen (N-Acetyl-4-aminophenol) by Brassica juncea, drug-induced defense responses and detoxification mechanisms in different plant parts. 相似文献563.

Introduction
Within the last decade, numerous studies have investigated the role of environmental history on tolerance to stress of many organisms. This study aims to assess if Manila clams Ruditapes philippinarum may react differently to cadmium exposure and trematode parasite infection (Himasthla elongata) depending on their origin and environmental history in Arcachon Bay (France). 相似文献565.
Southern Chile encompasses one of the most extensive fjord regions of the world, the Patagonia, currently exposed to natural
and anthropogenic perturbations. These fjord ecosystems provide important services to humans, which have not been adequately
measured and valued. As a consequence, ecosystem services are commonly ignored in public policy design and in the evaluation
of development projects. Here we tackle questions that are highly relevant for the nation’s development, namely (1) understanding
fjord functioning, and (2) developing management strategies based on ecosystem services, in order to secure simultaneous and
adequate use of these ecosystems which area influenced by ecological (e.g., biogeochemical) and productive (e.g., aquaculture,
fisheries) processes. We also seek to strengthen the analysis of fjord ecosystem value from the economical (including coastal
zoning), socio-cultural, institutional, and governmental points of view. In addition, the investigation of current and future
effects of climate change on this large region offers a unique opportunity to understand the social and economic consequences
of a global phenomenon at local to regional scales. Biogeochemical and socio-economic models will be used to simulate future
scenarios under a gamut of management options. 相似文献

Background
The Atacama Desert in Northern Chile is one of the most arid places on earth. However, fog occurs regularly at the coastal mountain range and can be collected at different sites in Chile to supply settlements at the coast with freshwater. This is also planned in the fog oasis Alto Patache (20°49′S, 70°09′W). For this pilot study, we collected fog water samples in July and August 2008 for chemical analysis to find indications for its suitability for domestic use. 相似文献567.

Background, aim, and scope
Carbonyl compounds have been paid more and more attention because some carbonyl species have been proven to be carcinogenic or a risk for human health. Plant leaves are both an important emission source and an important sink of carbonyl compounds. But the research on carbonyl compounds from plant leaves is very scarce. In order to make an approach to the emission mechanism of plant leaves, a new method was established to extract carbonyl compounds from fresh plant leaves. 相似文献568.

Background, aim and scope
European legislation stipulates that genetically modified organisms (GMO) have to be monitored to identify potential adverse environmental effects. A wealth of different types of monitoring data from various sources including existing environmental monitoring programmes is expected to accumulate. This requires an information system to efficiently structure, process and evaluate the monitoring data. 相似文献569.

The Fallacies of Concurrent Climate Policy Efforts 总被引:1,自引:0,他引:1
Marian Radetzki 《Ambio》2010,39(3):211-222
Climate policy has assumed an extreme degree of urgency in the international debate in recent years. This article begins by
taking a critical look at the scientific underpinnings of the efforts to stabilize the climate. It points to several serious
question marks on the purported relationship between greenhouse gas emissions and global warming, and expresses distrust about
claims of impending catastrophes related to rising sea levels, hurricanes, and spread of infectious disease. It then reviews
the concurrent climate policy efforts and concludes that they are incoherent, misguided and unduly costly, and that they have
so far had no perceptible impact on anthropogenic greenhouse gas emissions. The exceedingly ambitious policy plans currently
under preparation suffer from similar fallacies. For these reasons, but also because of the remaining scientific doubts and
the exorbitant costs that have to be incurred, skepticism is expressed about the preparedness to implement the climate policy
plans currently on the table. 相似文献
