Aluminium in health and food: a gradual global approach

Abstract: The history of occupational diseases and environment gives little consideration to pathologies related to the use of artefacts. Furthermore, materials are seldom the centre of studies. In this article, aluminium is used as an example for understanding the processes of user acceptance and rejection. The issue of user confidence over long periods of time is raised from the actors' perspective and with respect to the relationships between companies, scientists, public actors, citizens and users. Since the time that aluminium was first produced, it was subjected to physicochemical tests. Scientists concluded that it was harmless. With mass production, starting in 1886, the debate was reopened, in particular because of its use for military purposes. Simultaneously, the arrival of new smelters caused local public reaction against pollution and occupational diseases. From the 1960s, the development of mass pollution generated a geographical widening of the debates. Companies had to confront national associations...

Histoire de controverses : l’aluminium et le risque alimentaire, du XIXe siècle à l’entre-deux-guerres

Abstract: Le developpement de l’aluminium s’est accompagne de crises et polemiques importantes, en particulier dans le champ des applications alimentaires. Parce que l’alumine contamine les aliments et que les sels d’aluminium sont utilises sous forme d’additifs alimentaires, la question de son innocuite, soulevee des le debut du XIXe siecle pour son oxyde, est inherente a son histoire. Son emploi dans la levure chimique aux Etats-Unis a declenche la plus importante controverse scientifique de son epoque. Deux autres controverses sont survenues en Europe, entre la fin du XIXe siecle et les annees 1930. Toutes ont souleve une question essentielle : comment ce metal migre-t-il dans les tissus et les organes des etres vivants ? Les debats et les recherches scientifiques ont rapidement ete influences et freines par differentes interventions des industriels, tandis que la societe civile etait encore peu presente.

Human exposure to aluminium

Abstract: Human activities have circumvented the efficient geochemical cycling of aluminium within the lithosphere and therewith opened a door, which was previously only ajar, onto the biotic cycle to instigate and promote the accumulation of aluminium in biota and especially humans. Neither these relatively recent activities nor the entry of aluminium into the living cycle are showing any signs of abating and it is thus now imperative that we understand as fully as possible how humans are exposed to aluminium and the future consequences of a burgeoning exposure and body burden. The aluminium age is upon us and there is now an urgent need to understand how to live safely and effectively with aluminium.

The Sex of Things: Gender and Consumption in Historical Perspective

Abstract: Why Gender Matters-Leonard Sax 2017 A revised and updated edition (with more than 70% new material) of the evergreen classic about the innate differences between boys and girls and how best to parent and teach girls and boys successfully, with completely new chapters on sexual orientation and on transgender and intersex kids. Eleven years ago, Why Gender Matters broke ground in illuminating the differences between boys and girls--how they perceive the world differently, how they learn differently, how they process emotions and take risks differently. Dr. Sax argued that in failing to recognize these hardwired differences between boys and girls, we ended up reinforcing damaging stereotypes, medicalizing normal behavior (see: the rising rates of ADHD diagnosis), and failing to support kids to reach their full potential. In the intervening decade, the world has changed drastically, with an avalanche of new research which supports, deepens, and expands Dr. Sax's work. This revised and updated edition includes new findings about how boys and girls interact differently with social media and video games; a completely new discussion of research on gender non-conforming, LGB, and transgender kids, new findings about how girls and boys see differently, hear differently, and even smell differently; and new material about the medicalization of bad behavior.
