Bioaccumulation and Toxicity of Organic Chemicals in Terrestrial Invertebrates
Terrestrial invertebrates are key components in ecosystems, with crucial roles in soil structure, functioning, and ecosystem services. The present chapter covers how terrestrial invertebrates are impacted by organic chemicals, focusing on up-to-date information regarding bioavailability, exposure routes and general concepts on bioaccumulation, toxicity, and existing models. Terrestrial invertebrates are exposed to organic chemicals through different routes, which are dependent on both the organismal traits and nature of exposure, including chemical properties and media characteristics. Bioaccumulation and toxicity data for several groups of organic chemicals are presented and discussed, attempting to cover plant protection products (herbicides, insecticides, fungicides, and molluscicides), veterinary and human pharmaceuticals, polycyclic aromatic compounds, polychlorinated biphenyls, flame retardants, and personal care products. Chemical mixtures are also discussed bearing in mind that chemicals appear simultaneously in the environment. The biomagnification of organic chemicals is considered in light of the consumption of terrestrial invertebrates as novel feed and food sources. This chapter highlights how science has contributed with data from the last 5 years, providing evidence on bioavailability, bioaccumulation, and toxicity derived from exposure to organic chemicals, including insights into the main challenges and shortcomings to extrapolate results to real exposure scenarios
Ecuador's experiment in living well:Sumak kawsay, Spinoza and the inadequacy of ideas
In April 2017 Ecuador halted the continental drift to the conservative right in Latin America by electing leftist Lenín Moreno to the Presidency. Attention has turned, therefore, to the legacy of outgoing President Rafael Correa’s decade in power. To that end, this paper examines one of Correa’s signature programmes, ‘Buen Vivir’ (Living Well), a strategic plan for development underscored by the indigenous Kichwa cosmology of ‘sumak kawsay’. Sumak kawsay is a notion that has been co-opted into policy mechanisms in an attempt to both challenge neoliberal modes of governance, and to disrupt the ontological bifurcation of nature and society. Given the emphasis placed on ecological sensibility in sumak kawsay and Buen Vivir, critics have been quick to highlight the contradictory relations between Ecuador’s mode of environmental governance and its extractivist agenda. Such critiques are as staid as they are well rehearsed. Acknowledging the precarious composition of sumak kawsay, the paper questions the extent to which the ethos of experimentalism in politics can be sustained, eliding stymied technocratic forms of the political. It turns, therefore, to Baruch Spinoza’s treatise on adequate and inadequate ideas. In so doing, the paper examines how one can critique an idea without perpetuating a moral economy in judgment. Consequently, the paper considers the way in which Spinoza’s thought can be charged to recuperate imperilled political ideas
