TABLE 3.

Muscle Fiber Diameter Changes in Arsenic-Exposed Killifish

Fiber size (μm)	Fold change in arsenic-exposed fish
1–3	1.4
4–6	1.7*
7–9	1.2*
10–12	1.6*
13–15	3.8*
16–18	7.5

Note. Data are the fold change in the percentage of fibers at a particular class size.

*Statistically different using Student’s t-test (p ≤ 0.05).
