an assessment of total mercury in sediments
an assessment of the percent of total mercury in methyl form
and an assessment of the level of mercury in biota.
The findings of the prototype investigations showed:
low to non-detectable levels of total mercury in sediments;
little, if any, evidence of bioavailability of mercury as measured by the
percent of total mercury in methylated form, and
no evidence of harm to aquatic biota as measured by total mercury in
biological tissue.
The results of the demonstration removal program indicated that battery
removals may have a short-term effect of elevating the level of mercury in
sediments immediately following removals.
