Rather than traces, there is an abundance of toxicity. I could drown in the field of representation when I search for Delhi's air online. The problem for me is to find erasures of toxicity, both in terms of how unequal breathing exposures are represented scientifically and visually, and of how toxic histories of disposession are (not) grappled with in this field of representation.
The notion of "trace" in the archive becomes more of a remedy to toxicity. Trace comes to mean a slight sign of what is excluded, a means of interrogating the silences in the archive.
