What is in the air? What do we breathe?

In the 35th MUR BRUT exhibition, Enya Burger captures the invisible - not as a snapshot, but as a slow trace. Clamped in a grid of aluminum, subtle color changes unfold on pH-sensitive paper treated with bromophenol blue: a process triggered by the air we breathe in the parking garage.

The treated paper reacts to CO₂ and NO₂ - invisible traces of traffic. The gases form acids that lower the pH value and gradually trigger a color change from a deep blue to a bright yellow. Areas that are sealed remain unaffected. This gradually creates an image: a chemical imprint of the surrounding air, a technical fossil.

The title Residual Unit refers to what remains, what is left over - but also to what is measurable, to what is not immediately obvious.
Burger installs a question that can be read both ecologically and politically: What's in the air? The work eludes control, it develops over time. The parking garage becomes a resonance chamber, a measuring chamber, the artwork a sensitive surface that documents environmental change - visible, silent, subversive.
