SECTION 12
ECOLOGICAL DATA
Chromium in soil can be transported to the atmosphere by way of aerosol formation. Chromium is also transported from soil through
runoff and leaking of water. Runoff could remove both chromium ions and bulk precipitates of chromium, with final deposition on either
a different land area or a water bod. Chromium is removed from air through wet and dry depositions. Terrestrial Fate: Lead in soil is
relatively immobile and can persist for long periods of time, whether added to the soil as halides, hydroxides, oxides, carbonates, and
sulfates.
