What does this visualization (including caption) say about toxics?

The images in this essay contribute to a sense that toxicity prompts, and is caught up in, political and social discourses. The commentary tells the viewer that we might only understand ambiguous, atmospheric toxcities through the lenses provided by science, media, and political statements. Toxics are therefore not seen as particles, but through words, images, attempts to provoke action. They are therefore affective existents in themselves.
