Five thousand years of atmospheric Ni,Zn, As,and Cd deposition recorded in bogs from NW Iberia: prehistoric and historic anthropogenic contributions

The analysis of environmental archives from across the world has demonstrated that human perturbation of the geochemical cycles of trace metals and the resultant atmospheric metal contamination date back, at least, several millennia. However, an understanding of the local processes and timing of changes in trace metal deposition is also essential for a proper global interpretation. The Iberian Peninsula was a major mining area since prehistoric times and the analysis of environmental archives provides a good opportunity to improve our understanding of the history of mining and metallurgy in Europe. We present the results from three ¹⁴C dated peat cores from the Xistral Mountains (NW Iberia). These records are used to reconstruct past atmospheric deposition of Ni, Zn, As, and Cd. The chronology of the changes in concentrations and metal accumulation rates was found to be concordant in the three bogs, and showed great similarity to total Pb, Hg, and Pb isotope ratios as determined in previous investigations. They present a consistent view of changes in atmospheric pollution and the importance of metals in the development of human societies, especially: i) the first evidence of atmospheric metal pollution 3400 years ago, which is simultaneous with the expansion of the Atlantic Bronze Koine; ii) a pollution event between 2350 and 2150 years ago, associated to the development of so-called Celtic culture (local Late Iron Age); iii) a dramatic increase of metal fluxes in Roman times; iv) a severe and rapid increase in the last 250 years corresponding to the beginning of the industrial revolution in Europe, reflecting the emergence of the new dominant sources of pollution, and v) the increase of long range atmospheric transport of pollutants. Our data suggest that all detected ancient (until ca. 1450 cal BP) periods of enhanced Ni, Zn, As, and Cd accumulation may have had an anthropogenic origin, related to the onset and development of mining and metallurgy.

Edna O'Brien and narrative diaspora space

Given the persistent presence of migration in the work of Edna O'Brien, it is surprising how marginal a theme it is in critiques of her work. This article explores how questions of diaspora have reached a renewed level of depth and intensity in her novel The Light of Evening (2006) and the related short story ‘My Two Mothers’ (2011). Looking, in particular, at how letters play a central role in the relationships of three generations of Irish women across three countries, it analyses how issues of mother(land), diaspora and belonging are mediated through migrant fiction. It draws on the work of Avtar Brah and Paul Ricoeur to argue that, along with related forms of textuality within O'Brien's oeuvre, letters represent a ‘narrative diaspora space’ which illuminates the relationship between mothers, daughters and writing in Irish migrant experience.     

The Conservation of English Cultural Built Heritage: A Force for Social Inclusion?

Debates about the socially inclusionary potential of heritage have to date focused principally on heritage sites and museums. Relatively little attention has been paid to the wider Cultural Built Heritage (CBH) that surrounds us in our everyday lives. This paper starts with a brief theoretical exploration of the social role of heritage and the key policy background. Then, based on an understanding of policy and action in England, this paper sets out a framework for considering how this wider CBH might contribute to social inclusion. A fundamental binary divide is made between the role of CBH as historic places and opportunity spaces in which regeneration may occur. However, in neither case is action necessarily socially inclusive. The paper concludes that a greater clarity of objectives and definitions is necessary if CBH is to meet its potential to be socially inclusionary.
