contamination (if any) in sediments associated with spent batteries, no human

health risk and minimal biological impacts.

Chesapeake Bay

Mercury concentrations in sediments adjacent to AtoNs in the Baltimore Area of

the Chesapeake Bay were generally the lowest found in all the prototype

investigations. The values at the three AtoNs evaluated were low compared to

background levels both measured and reported in the literature (Long and

MacDonald 1992). (Figure 3-1). The levels were also below ecological effects

range low (ER-L) and effects range median (ER-M) which are ecological

benchmark concentrations. A full description of the sources of these values

and the method of their calculation appears in Appendix C.
