Elemental distributions in MeHg exposed and unexposed zebrafish. Comparison of elemental distributions for Hg, Ca, and Zn in sections of fish heads from 4.5-dpf larvae exposed for 24 h to 100 µM MeHg-l-cysteine (Upper) with those from control fish (Lower), measured using x-ray fluorescence imaging. Each section is paired with its respective histological image (Left). Quantities of the individual elements are plotted on the same (arbitrary) scale for Hg exposed and control sections (Hg scale from 0 to 0.96 µg/cm2).
