Emerging contaminants are a wide group of compounds that include several classes of organic substances. Personal care products, pharmaceuticals, pesticides, industrial additives, monomers and plasticizers are examples of compounds included in emerging contaminants. In this work, four chemicals representing four classes of organic contaminants were investigated: salicylic acid, representing drugs; bisphenol A, a monomer widely used in the production of polymeric products; methylparaben, used as a preservative in cosmetics; and irgarol, a biocide used in agriculture and antifouling paints. A previously validated method based on liquid chromatography coupled with mass spectrometry was employed to determine the trace-levels of those compounds in ocean waters around King George Island, Antarctica. Salicylic acid and bisphenol A were found in many of the 20 samples investigated, which were collected on the northwest and southeast coasts of the island. Methylparaben and irgarol were found at low levels, each with only one occurrence. Although salicylic acid may originate in the biosynthesis of phenylalanine, the distribution and absence of this substance at some points suggest an anthropic origin. Bisphenol A was found in several sampling points, demonstrating contamination by plastics even though no correlation was found between these two compounds.

Warming across ice-covered regions will result in changes to both the physical and climatic environment, revealing new ice-free habitat and new climatically suitable habitats for non-native species establishment. Recent studies have independently quantified each of these aspects in Antarctica, where ice-free areas form crucial habitat for the majority of terrestrial biodiversity. Here we synthesise projections of Antarctic ice-free area expansion, recent spatial predictions of non-native species risk, and the frequency of human activities to quantify how these facets of anthropogenic change may interact now and in the future. Under a high-emissions future climate scenario, over a quarter of ice-free area and over 80 % of the ~14 thousand km2 of newly uncovered ice-free area could be vulnerable to invasion by one or more of the modelled non-native species by the end of the century. Ice-free areas identified as vulnerable to non-native species establishment were significantly closer to human activity than unsuitable areas were. Furthermore, almost half of the new vulnerable ice-free area is within 20 km of a site of current human activity. The Antarctic Peninsula, where human activity is heavily concentrated, will be at particular risk. The implications of this for conservation values of Antarctica and the management efforts required to mitigate against it are in need of urgent consideration.

Pierre Aubenque’s “Science Regained” (1962; translated by Clayton Shoppa) was originally published as the concluding chapter of Le Problème de l’Être chez Aristote, one of the most important and original books on Aristotle’s Metaphysics. In this essay, Aubenque contends that the impasses which beset the project of first philosophy paradoxically become its greatest accomplishments. Although science stabilizes motion and thereby introduces necessity into human cognition, human thought always occurs amidst an inescapable movement of change and contingency. Aristotle’s ontology, as a discourse that strives to achieve being in its unity, succeeds by means of the failure of the structure of its own approach: the search of philosophy – dialectic – becomes the philosophy of the search. Aubenque traces this same structure of scission, mediation, and recovery across Aristotelian discussions of theology, motion, time, imitation, and human activity.
