STUDIES AND INVESTIGATIONS
Laboratory Studies
The laboratory studies at the Massachusetts Institute of Technology and at the
University of Maryland analyzed spent batteries for total mercury and the
solubility of mercury under salt water conditions. The form of mercury in
spent batteries (elemental, organic, or ionic) was also determined. The
laboratories measured the likelihood of release using a standard US
described mercury transport mechanisms. The results of TCLP analyses confirmed
that the mercury present in spent primary batteries was at low concentrations
and generally undetectable using the standard TCLP procedure (Mason, 1995).
AtoN Sites Prototype Investigations
The AtoNs that were investigated within the four prototype locations are listed
in Table S-1. The following data are given for each AtoN studied:
(1)
batteries found during investigation
(2)
estimated maximum number of batteries assuming that all spent
batteries were disposed of at the site
(3)
type of bottom (e.g. mud, sand, etc.)
(4)
the percent of AtoN sites in the corresponding USCG district
that have a similar bottom type
(5)
the water depth at the time of site investigation
(6)
description of the aquatic environment
