Exploring Epoxy Use at the Oak Ridge K-25 Facility and New Concerns about Neurotoxic Risks

Epoxies are used widely in industrial and domestic applications, and apart from carcinogenic concerns, they are best known as both sensitizers and irritants in terms of dermatological and respiratory impacts. Neurological impacts from epoxy use, however, have not been reported thus far in the occupational or environmental health literature. This project was designed to further the understanding of epoxy materials and their applications in terms of the potential for harmful exposures, to understand what is presented in the industry, agency, and other scientific literature relative to exposure opportunities and the potential for neurotoxic impacts, and to document past usage of epoxies at the K-25 facility as a representation of circumstances involving higher exposures. With this information a public health strategy specific to the K-25 population and the epoxy industry as a whole was to be formulated to address potential neurotoxic concerns including the need for further medical care, industrial hygiene measurements, protective measures, toxicology, and epidemiology. To accomplish these tasks, comprehensive and current industry textbooks and literature were reviewed on epoxy formulation and usage. Key epoxy constituents were identified to complete the search for any existing literature on neurotoxic findings. Regulatory or agency investigations were explored to identify what is known thus far about exposures to these constituents and effects on workers. Relative to K-25 activities, a formal survey instrument was developed for information gathering purposes only, to ask workers about typical epoxy use practices, and to gain an understanding of the potential level of epoxy exposures in these settings. This research was completed money allocated during Round 5 of the Citizens’ Monitoring and Technical Assessment Fund (MTA Fund). Clark University was named conservator of these works.

Sustainable Agricultural Productivity Growth and Bridging the Gap for Small-Family Farms: Interagency Report to the Mexican G20 Presidency

In 2011, G20 leaders committed to sustainably increase agricultural (production and) productivity (paragraph 43 of the Cannes Declaration). They "agree(d) to further invest in agriculture, in particular in the poorest countries, and bearing in mind the importance of smallholders, through responsible public and private investment," they "decide(d) to invest in research and development of agricultural productivity. Early in 2012 Mexico, as G20 President, invited international organisations to examine practical actions that could be undertaken to sustainably improve agricultural productivity growth, in particular on small family farms. The preparation of this report, co-ordinated by the FAO and the OECD, responds to this request. It is a collaborative undertaking by Bioversity, CGIAR Consortium, FAO, IFAD, IFPRI, IICA, OECD, UNCTAD, Coordination team of UN High Level Task Force on the Food Security Crisis, WFP, World Bank, and WTO. We, the international organisations, are pleased to provide you with this joint report and look forward to continuing collaboration within the G20 framework to further elaborate and, as appropriate, implement the recommendations that it contains

Macroalgae Decrease Growth and Alter Microbial Community Structure of the Reef-Building Coral, Porites astreoides

This is the publisher’s final pdf. The published article is copyrighted by the Public Library of Science and can be found at: http://www.plosone.org/home.action.With the continued and unprecedented decline of coral reefs worldwide, evaluating the factors that contribute to coral demise is of critical importance. As coral cover declines, macroalgae are becoming more common on tropical reefs. Interactions between these macroalgae and corals may alter the coral microbiome, which is thought to play an important role in colony health and survival. Together, such changes in benthic macroalgae and in the coral microbiome may result in a feedback mechanism that contributes to additional coral cover loss. To determine if macroalgae alter the coral microbiome, we conducted a field-based experiment in which the coral Porites astreoides was placed in competition with five species of macroalgae. Macroalgal contact increased variance in the coral-associated microbial community, and two algal species significantly altered microbial community composition. All macroalgae caused the disappearance of a γ-proteobacterium previously hypothesized to be an important mutualist of P. astreoides. Macroalgal contact also triggered: 1) increases or 2) decreases in microbial taxa already present in corals, 3) establishment of new taxa to the coral microbiome, and 4) vectoring and growth of microbial taxa from the macroalgae to the coral. Furthermore, macroalgal competition decreased coral growth rates by an average of 36.8%. Overall, this study found that competition between corals and certain species of macroalgae leads to an altered coral microbiome, providing a potential mechanism by which macroalgae-coral interactions reduce coral health and lead to coral loss on impacted reefs

Biofuels and the role of space in sustainable innovation journeys

This paper aims to identify the lessons that should be learnt from how biofuels have been envisioned from the aftermath of the oil shocks of the 1970s to the present,and how these visions compare with biofuel production networks emerging in the 2000s. Working at the interface of sustainable innovation journey research and geographical theories on the spatial unevenness of sustainability transition projects,we show how the biofuels controversy is linked to characteristics of globalised industrial agricultural systems. The legitimacy problems of biofuels cannot be addressed by sustainability indicators or new technologies alone since they arise from the spatial ordering of biofuel production. In the 1970-80s, promoters of bioenergy anticipated current concerns about food security implications but envisioned bioenergy production to be territorially embedded at national or local scales where these issues would be managed. Where the territorial and scalar vision was breached, it was to imagine poorer countries exporting higher-value biofuel to the North rather than the raw material as in the controversial global biomass commodity chains of today. However, controversy now extends to the global impacts of national biofuel systems on food security and greenhouse gas emissions, and to their local impacts becoming more widely known. South/South and North/North trade conflicts are also emerging as are questions over biodegradable wastes and agricultural residues as global commodities. As assumptions of a food-versus-fuel conflict have come to be challenged, legitimacy questions over global agri-business and trade are spotlighted even further. In this context, visions of biofuel development that address these broader issues might be promising. These include large-scale biomass-for-fuel models in Europe that would transform global trade rules to allow small farmers in the global South to compete, and smallscale biofuel systems developed to address local energy needs in the South
