I looked through the string of images and am hoping to keep a running annotation all three of them. They are beautiful. I am not certain what I am looking at, though, and whether this is part of the (analytical) point? Are these images/is this image a kernel of maize? Is it a single soil particle? Is this first image chromatically different from the other three in its muted coloring because of agrotoxins, or are the others that much more "alive" because of the chemicals? The image thus holds me in suspense. I am not sure whether it opens up the concept of toxicity so much as suspends it, momentarily, until I can place it chromatically, toxically, and analytically.
the center of a chromatogram (if that's the right word for this) is where a sample is first placed but it becomes a blank spot as it is drawn out radially. toxicity only becomes visible or evident in its downstream, down-time after effects.
