It tells us that there are still many unknowns about how toxics affect the body and where they go. The body (as a site) is also largely unknown, and so the image and caption reveal a delicacy and wonder to the ways in which toxics operate, opening us to caring for bodies and seeing chemicals in a new light.
Perhaps highlighting the specific interstices in the image? Editing with toxics in the interstices or something like that?
The image is found, from https://www.brmi.online/lymph?lightbox=dataItem-jk75ve9g.
The nature of the image (a watercolour painting) is such that it adds a poeticness to the caption. It represents the caption well.
Could you perhaps explain a little more about the case study of war veterans to really bring the ethnography to the forefront?
The picture and caption are great. Extremely interesting. They communicate the importance and complexity of the interstitial in understanding how toxics affect the body. It advances ethnographic insight through drawing attention to a previously unknown space of toxic agency and affect. I would hesitate to call the interstitial 'less material' than the 'more material' structures, though.
