THE AESTHETICS OF URBAN METABOLISM: Landscape, Design and the Politics of In/Visibility

International Journal of Urban and Regional Research, EarlyView.
Abstract In this article, we chart the evolving aesthetic contours of urban metabolism across London, focusing on the River Lea and Thamesmead to the north and south of the River Thames, respectively. We begin in the nineteenth century, when these two sites formed critical nodes within a new sewerage system that relegated the city’s circulatory flows ...

REPRESENTING POLLUTION AT THE AGRARIAN–URBAN FRONTIER: Participatory Documentary Film‐Making in Bar Elias, Lebanon

International Journal of Urban and Regional Research, EarlyView.
Abstract The Beqaa Valley in Lebanon has become increasingly polluted, and residents are attributing illness to improper waste disposal and dumping. This article explores local epistemologies of pollution’s causes and effects in three films, which were researched and produced by local residents of Bar Elias, a small town in the Beqaa, which has rapidly

Postmortem submergence interval (PMSI) and human decomposition in anthropogenically constructed aqueous environments (pools, bathtubs, hot tubs, and spas)

Journal of Forensic Sciences, EarlyView.
Abstract Postmortem decomposition changes of bodies in aquatic environments may offer valuable insights into the postmortem submergence interval (PMSI) for medicolegal death investigators. However, the effects of immersion on the onset of such changes are poorly understood.

Passive environmental DNA sampling: A review of current practices, limitations and future directions for biodiversity monitoring

Methods in Ecology and Evolution, EarlyView.
Abstract Passive environmental DNA (eDNA) sampling is rapidly emerging as a powerful alternative to active sampling methods (e.g. direct water sampling), with a rapidly growing diversity of tested approaches but little methodological convergence.

PFAS from a Discrete‐Event Terrestrial Source Migrates with Groundwater to Intertidal Seepages

Groundwater, EarlyView.
PFAS is conveyed to the coastal intertidal zone from sources across the terrestrial landscape. Discharge of PFAS into the coastal ecosystem is complicated in space and time by the ongoing bi‐directional exchange of terrestrial groundwater and ocean water driven by tidal pumping within discharge areas.
