| Notes: Only
anthropogenic categories which are quantifiable have been included. Mercury emissions
from landfill volatilization have not been quantified.
Mercury is no longer used in paints, turf products or pigment in the U.S.
Significant digits of inventory values are not indicative of the accuracy of the
estimates.
Refuse derived fuel was previously not included in the inventory. |
