Abstract
Pesticide exposure in Ecuador's banana industry reflects political economic and ecological processes that interact across scales to affect human health. We use this case study to illustrate opportunities for applying political ecology of health scholarship in the burgeoning field of global health. Drawing on an historical literature review and ethnographic data collected in Ecuador's El Oro province, we present three main areas where a political ecological approach can enrich global health scholarship: perceptive characterization of multi-scalar and ecologically entangled pathways to health outcomes; critical analysis of discursive dynamics such as competing scalar narratives; and appreciation of the environment-linked subjectivities and emotions of people experiencing globalized health impacts. Rapprochement between these fields may also provide political ecologists with access to valuable empirical data on health outcomes, venues for engaged scholarship, and opportunities to synthesize numerous insightful case studies and discern broader patterns.

Abstract
There has been growing policy interest in social justice issues related to both health and food. We sought to understand the state of knowledge on relationships between health equity--i.e. health inequalities that are socially produced--and food systems, where the concepts of 'food security' and 'food sovereignty' are prominent. We undertook exploratory scoping and mapping stages of a 'meta-narrative synthesis' on pathways from global food systems to health equity outcomes. The review was oriented by a conceptual framework delineating eight pathways to health (in)equity through the food system: 1--Multi-Scalar Environmental, Social Context; 2--Occupational Exposures; 3--Environmental Change; 4--Traditional Livelihoods, Cultural Continuity; 5--Intake of Contaminants; 6--Nutrition; 7--Social Determinants of Health and 8--Political, Economic and Regulatory context. The terms 'food security' and 'food sovereignty' were, respectively, paired with a series of health equity-related terms. Combinations of health equity and food security (1414 citations) greatly outnumbered pairings with food sovereignty (18 citations). Prominent crosscutting themes that were observed included climate change, biotechnology, gender, racialization, indigeneity, poverty, citizenship and HIV as well as institutional barriers to reducing health inequities in the food system. The literature indicates that food sovereignty-based approaches to health in specific contexts, such as advancing healthy school food systems, promoting soil fertility, gender equity and nutrition, and addressing structural racism, can complement the longer-term socio-political restructuring processes that health equity requires. Our conceptual model offers a useful starting point for identifying interventions with strong potential to promote health equity. A research agenda to explore project-based interventions in the food system along these pathways can support the identification of ways to strengthen both food sovereignty and health equity.

Rother HA. Communicating pesticide neurotoxicity research findings and risks to decision-makers and the public. Neurotoxicology 2014; 45:327-37. [PMID: 24642183 DOI: 10.1016/j.neuro.2014.03.001] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2013] [Revised: 02/22/2014] [Accepted: 03/06/2014] [Indexed: 11/17/2022]
Abstract
The extensive research findings on neurotoxic risks of pesticides tend to remain in academic publications rather than being comprehensibly communicated to decision-makers and the public. Protecting health and promoting risk reduction, particularly in developing countries, requires access to current findings in a format that can inform policy, regulations, behaviour change and risk reduction. Successfully communicating research findings may require multiple strategies depending on the target audience's varying comprehension skills (e.g., numeracy literacy, visual literacy) and ability to interpret scientific data. To illustrate the complexities of risk communication, a case study of exposure to neurotoxic street pesticides amongst poor, urban South African communities attempting to control poverty related pests, is presented. What remains a challenge is how to communicate neurotoxicity research findings consistently and in a meaningful manner for a lay audience, consisting of both the general public and decision makers. A further challenge is to identify who will monitor and evaluate the ways in which these findings are communicated to ensure quality is maintained. Ultimately, researchers should carry the responsibility of knowledge translation and engaging with communication specialists when appropriate. Additionally, institutions should reward this as part of promotion and academic accolade systems, and funders should fund the translational process. Ethics review boards should also play an instrumental role in ensuring that knowledge translation is part of the ethics review requirement, while professional societies should take more responsibility for disseminating research findings to non-academics.

Abstract
The fact that a conference on neurotoxicity was held in China triggered the idea to provide an insight into occupational diseases, their development and the approaches to investigate them in Asian countries. A historical review, a meta-analysis, and studies on humans and animals provide impressions on past and current problems. The Korean example showed that each newly introduced industry is accompanied by its own problems as regards occupational diseases. Mercury and carbon disulfide were of importance in the beginning, whereas solvents and manganese became important later. Outbreaks of diseases were important reasons to guide both the public and the governmental attention to prevention and allowed within a relatively short time considerable progress. As the example on the replacement of 2-bromopropane by 1-bromopropane showed, also the introduction of chemicals that are more beneficial for the environment may result in additional occupational risks. A lower mutagenicity of 1-bromopopane was shown to be associated with a greater neurotoxicity in Japanese studies. Although occupational health and diseases are commonly related to adults, child workers exposed to solvents were examined in a Lebanese study. The study started outlining the health hazards in young workers because they might be at a much greater risk due to the not yet completed maturation of their nervous system. That some occupational diseases are not yet a focus of prevention was shown by the study on pesticides. If at all, the serious health consequences resulting from excessive exposure were investigated. Research enabling precautionary actions was not available from the international literature. Despite globalization the knowledge on occupational diseases is not yet "globalized" and each country obviously undergoes its own development triggered by local experiences. Economic development that requires a healthy workforce, but also public interest that challenges governmental regulations further efforts on the prevention of occupational diseases. The paper reflects a summary of the talks presented at the symposium "Occupational Neurotoxicities in Asian Countries" as part of the 11th International Symposium on Neurobehavioral Methods and Effects in Occupational and Environmental Health.

[PMID: 21776202 PMCID: PMC3137997 DOI: 10.3390/ijerph8061792] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/18/2011] [Revised: 05/13/2011] [Accepted: 05/17/2011] [Indexed: 11/29/2022]
Abstract
The effects of pesticides on the general population, largely as a result of dietary exposure, are unclear. Adopting an organic diet appears to be an obvious solution for reducing dietary pesticide exposure and this is supported by biomonitoring studies in children. However, results of research into the effects of organic diets on pesticide exposure are difficult to interpret in light of the many complexities. Therefore future studies must be carefully designed. While biomonitoring can account for differences in overall exposure it cannot necessarily attribute the source. Due diligence must be given to appropriate selection of participants, target pesticides and analytical methods to ensure that the data generated will be both scientifically rigorous and clinically useful, while minimising the costs and difficulties associated with biomonitoring studies. Study design must also consider confounders such as the unpredictable nature of chemicals and inter- and intra-individual differences in exposure and other factors that might influence susceptibility to disease. Currently the most useful measures are non-specific urinary metabolites that measure a range of organophosphate and synthetic pyrethroid insecticides. These pesticides are in common use, frequently detected in population studies and may provide a broader overview of the impact of an organic diet on pesticide exposure than pesticide-specific metabolites. More population based studies are needed for comparative purposes and improvements in analytical methods are required before many other compounds can be considered for assessment.
