The image and captions convey the literal toxicity of PM2.5 and its effects on the body. The use of an image with a colonial era monument in the backdrop further complicates the image's representation of toxicity.
This visualization parallels how PM 2.5 is trapped in the semi-permeability of a HEPA filter to the porosity of the lung organs, as well as the rest of bodily tissues. By extracting the lung from the body, its significance for human life is foregrounded without markers of race, class or gender, which creates a compelling contrast to other residues of colonial rule.
