ADS11 will participate in Bienal'25 Fotografia do Porto with the exhibition The Extraterritoriality of Toxicity. Using the Douro River as a case study, the exhibition explores the river as a fluid archive - a carrier of memory and living systems shaped by post-natural relations. It presents research into anthropogenic toxicity and its effects on human and more-than-human bodies, tracing the narratives, regulatory frameworks, and ownership regimes that sustain toxic landscapes and their diffuse impacts on ecologies and architectures.
