    AMEG: the new SETAC advisory group on aquatic macrophyte ecotoxicology

    Introduction and background Primary producers play critical structural and functional roles in aquatic ecosystems; therefore, it is imperative that the potential risks of toxicants to aquatic plants are adequately assessed in the risk assessment of chemicals. The standard required macrophyte test species is the floating (non-sediment-rooted) duckweed Lemna spp. This macrophyte species might not be representative of all floating, rooted, emergent, and submerged macrophyte species because of differences in the duration and mode of exposure; sensitivity to the specific toxic mode of action of the chemical; and species-specific traits (e.g., duckweed's very short generation time). Discussion and perspectives These topics were addressed during the workshop entitled “Aquatic Macrophyte Risk Assessment for Pesticides” (AMRAP) where a risk assessment scheme for aquatic macrophytes was proposed. Four working groups evolved from this workshop and were charged with the task of developing Tier 1 and higher-tier aquatic macrophyte risk assessment procedures. Subsequently, a SETAC Advisory Group, the Macrophyte Ecotoxicology Group (AMEG) was formed as an umbrella organization for various macrophyte working groups. The purpose of AMEG is to provide scientifically based guidance in all aspects of aquatic macrophyte testing in the laboratory and field, including prospective as well as retrospective risk assessments for chemicals. As AMEG expands, it will begin to address new topics including bioremediation and sustainable management of aquatic macrophytes in the context of ecosystem services

    Women write the rights of woman: The sexual politics of the personal pronoun in the 1790s

    No full text
    This article investigates patterns of personal pronoun usage in four texts written by women about women's rights during the 1790s: Mary Wollstonecraft's A Vindication of the Rights of Woman (1792), Mary Hays' An Appeal to the Men of Great Britain (1798), Mary Robinson's Letter to the Women of England (1799) and Mary Anne Radcliffe's The Female Advocate (1799). I begin by showing that at the time these texts were written there was a widespread assumption that both writers and readers of political pamphlets were, by default, male. As such, I argue, writing to women as a woman was distinctly problematic, not least because these default assumptions meant that even apparently gender-neutral pronouns such as I, we and you were in fact covertly gendered. I use the textual analysis programme WordSmith to identify the personal pronouns in my four texts, and discuss my results both quantitatively and qualitatively. I find that while one of my texts does little to disturb gender expectations through its deployment of personal pronouns, the other three all use personal pronouns that disrupt eighteenth century expectations about default male authorship and readership.

    Law, Environment, and the “Nondismal” Social Sciences

    Get PDF
    Over the past 30 years, the influence of economics over the study of environmental law and policy has expanded considerably, becoming in the process the predominant framework for analyzing regulations that address pollution, natural resource use, and other environmental issues. This review seeks to complement the expansion of economic reasoning and methodology within the field of environmental law and policy by identifying insights to be gleaned from various “nondismal” social sciences. In particular, three areas of inquiry are highlighted as illustrative of interdisciplinary work that might help to complement law and economics and, in some cases, compensate for it: the study of how human individuals perceive, judge, and decide; the observation and interpretation of how knowledge schemes are created, used, and regulated; and the analysis of how states and other actors coordinate through international and global regulatory regimes. The hope is to provide some examples of how environmental law and policy research can be improved by deeper and more diverse engagement with social science

    Geographies of shit: spatial and temporal variations in attitudes towards human waste

    Get PDF
    Taboos surrounding human waste have resulted in a lack of attention to spatial inequalities in access to sanitation and the consequences of this for human, environmental and economic health. This paper explores spaces where urgent environmental health imperatives intersect with deeply entrenched cultural norms surrounding human waste and the barriers they create for the development of more appropriate excreta management systems. The primary focus is on the global South (particularly India), although literature on sanitation histories in Europe and its colonies is drawn upon to illustrate spatial and temporal differences in cultural attitudes towards excrement
