Pollution in the open oceans: 2009-2013

This review of pollution in the open oceans updates a report on this topic prepared by GESAMP five years previously (Reports and Studies No. 79, GESAMP, 2009). The latter report, the first from GESAMP focusing specifically on the oceans beyond the 200 m depth contour, was prepared for purposes of the Assessment of Assessments, the preparatory phase of a regular process for assessing the state of the marine environment, led jointly by the United Nations Environment Programme (UNEP) and the Intergovernmental Oceanographic Commission (UNESCO-IOC)

Legacy pollutants are declining in Great Skuas (Stercorarius skua) but remain higher in Faroe Islands than in Scotland

To monitor environmental pollutants in Faroese biota, samples from a top predator were analysed and put into a spatial and temporal context. Analysis of 20 Great Skua eggs sampled in 2012 from the Faroe Islands showed >70 % lower concentrations of legacy persistent organic pollutants (POPs) than in samples analysed in 1977. The 2012 Faroese eggs showed higher concentrations than for eggs in Shetland from about the same period (2008). Eggshells were analysed for sub-lethal effects but there were no detectable effects of legacy POP levels on eggshell colour or thickness. A temporal decline in legacy POPs would indicate a reduction in the general pollutant levels present in the environment as has been shown in other areas of the North Atlantic, but there are significant geographic differences in POPs levels likely due to differences in diet resulting in significantly different exposures on a relatively limited spatial scale

2006 State of the Estuaries Report

The 2006 State of the Estuaries Report includes twelve indicators intended to report on the health and environmental quality of New Hampshire’s estuaries.The New Hampshire Estuaries Project (NHEP) developed and now implements a Monitoring Plan to track environmental indicators, inform management decisions, and report on environmental progress and status. The Monitoring Plan describes the methods and data for 34 indicators used to determine if the environmental goals and objectives of the Management Plan are being met. For each indicator, the Monitoring Plan defines the monitoring objective, management goal, data quality objectives, data analysis and statistical methods, and data sources. Just as implementation of the Management Plan for New Hampshire’s estuaries involves the collaboration of many organizations and agencies, the NHEP Monitoring Plan relies on data compiled from organizations that are leaders in the management and protection of the state’s estuaries and coastal watershed resources. Every three years, the NHEP prepares a State of the Estuaries report that includes information on the status and trends of a indicators from the coastal watershed and estuaries. The report provides the NHEP, natural resource managers, local officials, conservation organizations, and the public with information on the effects of management decisions and actions. Prior to developing each State of the Estuaries report, the NHEP publishes four technical data reports (“indicator reports”) that illustrate the status and trends of the complete collection of indicators tracked by the NHEP. Each report focuses on a different suite of indicators: Water Quality, Shellfish, Critical Habitats and Species, and Land Use and Development. These reports are available from the NHEP website, www.nhep.unh.edu. The 2006 State of the Estuaries Report communicates the status of 12 out of the 34 environmental indicators tracked by the NHEP. For each of these key indicators it provides the reader with the associated NHEP management goal and an explanation of supporting data. For some of the 12 indicators, additional information from supporting or related indicators is presented to further explain trends or to provide context for the primary indicators. The interpretations of the indicators in this report were peer reviewed by the 15 member NHEP Technical Advisory Committee and other experts in relevant fields, including university professors, researchers, and state and federal environmental managers from a variety of disciplines and perspectives. Therefore, the conclusions of this report represent the current scientific consensus regarding conditions in New Hampshire’s estuaries

High temporal discounters overvalue immediate rewards rather than undervalue future rewards : an event-related brain potential study

Impulsivity is characterized in part by heightened sensitivity to immediate relative to future rewards. Although previous research has suggested that "high discounters" in intertemporal choice tasks tend to prefer immediate over future rewards because they devalue the latter, it remains possible that they instead overvalue immediate rewards. To investigate this question, we recorded the reward positivity, a component of the event-related brain potential (ERP) associated with reward processing, with participants engaged in a task in which they received both immediate and future rewards and nonrewards. The participants also completed a temporal discounting task without ERP recording. We found that immediate but not future rewards elicited the reward positivity. High discounters also produced larger reward positivities to immediate rewards than did low discounters, indicating that high discounters relatively overvalued immediate rewards. These findings suggest that high discounters may be more motivated than low discounters to work for monetary rewards, irrespective of the time of arrival of the incentives

The Predatory Bird Monitoring Scheme (PBMS) Report 2006-7

The Predatory Bird Monitoring Scheme (PBMS) examines the levels of certain pollutants in selected wildlife species in Britain. It started in the 1960s to assess the impact of organochlorine pesticides on raptor populations, and the scheme is now the longest-running of its kind in the world. The aims of the PBMS are to monitor the levels of contaminants to determine how and why they vary between species and regions, how they are changing over time, and the risks they may have on individual birds and on their populations. Dead predatory birds are submitted to the PBMS by the public and by wildlife hospitals, veterinarian and zoological organisations. Eggs are collected, under licence, from a range of nests. The majority of these eggs are addled or deserted, although for some species, e.g. northern gannets, fresh egg are sampled. Second generation anticoagulant rodenticides (SGARs) are potentially toxic to all mammals and birds, and predators that feed upon rodents are particularly likely to be exposed to these compounds. Since 1983 the PBMS has monitored SGAR residues in barn owls, while kestrels have been monitored since 2001. The proportion of barn owls which have one or more SGARs in their liver increased from less than 10% in the 1980s to approximately 40% in the early 2000s. However, there has been a small decrease in this percentage in the last few years. A higher proportion of kestrels have detectable residues of SGARs in their liver than barn owls with 60% of birds received in the years 2001 to 2006 having one or more SGAR in their liver. There is no evidence of a change over time in the proportion ok kestrels with detectable liver SGAR residues. Overall, the high incidence of exposure amongst monitored species remains of concern. Sparrowhawk livers are analysed for a range of persistent organic pollutants (POPs) and heavy metals. Sparrowhawks are studied because they have a wide distribution across the Britain and can be used as a sentinel species for the terrestrial environment. Following restrictions on its use as an agricultural pesticide, mercury concentrations have declined in sparrowhawks. However, despite PCBs being banned in 1981, there has not been any long-term change in polychlorinated biphenyl (PCB) liver concentrations in sparrowhawks during the period 1968-2006. In herons, used as a sentinel species for freshwater habitats, both PCB and mercury concentrations have declined. In 2006, mean PCB and mercury concentrations in both species were below those thought to have an adverse effect on individual birds. Pollutants, such as mercury and PCBs, can affect development and hatchability.. Therefore, the PBMS monitors the levels of contaminants in the eggs of a range of species including those of conservation concern such as golden eagle and the re-introduced white-tailed sea eagle. Other species that are monitored are the northern gannet, which are used as a monitor of the marine environment, and merlin that hunt in upland habitats. In general, and specifically in 2006, the residues measured in the eggs of golden eagle and gannets are below those thought to have an adverse effect on bird eggs, but some residues in individual merlin eggs were at concentrations associated with effects in other species. Few white-tailed see eagle eggs are received for analysis by the PBMS but a large proportion of those eggs that have been analysed, including the egg collected in 2006, have DDE, PCB and mercury concentrations above levels associated with adverse effects on bird embryos and the hatching success of eggs. Despite the withdrawal of PCBs from manufacturing over 20 years ago, the evidence for declining PCB concentrations in predatory birds is equivocal, with declines in liver or egg residues in some species but not in others. Mercury concentrations in most species have not significantly changed during the monitoring period

Historicizing the Emergence of Global Mental Health in Nepal (1950-2019)

This article traces a genealogy of mental health governance in Nepal as it was constituted in and through an assemblage of historical events, local politics, personal relationships and trends in the field of global health development. The relation between health development and local politics in Nepal is explored across four periods in the history of global health: 1) the early health development programs of disease eradication after the end of the Rana oligarchy (1951-1970); 2) the turn to primary health care during the Panchayat (1970-1990); 3) the rise of NGOs and the People’s War (1990-2010); and 4) the return to health systems development in the post-conflict/post-earthquake period (2010-present). By drawing on a combination of archival research and a cross-disciplinary review of the literature on global mental health, this article tracks the changing projects of mental health development programs in Nepal over the past century. In doing so, it becomes possible to observe the shifting trends in the problematization of mental health and the management of psychic life in Nepal from 1950 to the emergence of global mental health
