Biological Impact of Exposure to Extremely Fine-Grained Volcanic Ash

Figure 2

Graph of weight change and survival in infected mice: (a) graphic representation of the body weight (g) of C57BL/6 mice after 7 days postinfection with volcanic ash at concentrations of 0.5 mg (green), 1 mg (purple), and 3.75 mg (orange); negative control (PBS, blue); and positive control (LPS, red). (b) Five groups of mice were uninfected (blue) and infected with volcanic ash at concentrations of 0.5 mg (green), 1 mg (purple), and 3.75 mg (orange) of volcanic ash or intraperitoneally infected with LPS (red), and survival were monitored daily for seven days. All data points for mice not infected or infected with LPS are in the same horizontal line.
