Effects of Dredged Materials on Zooplankton
A study was conducted to determine the potential impact of open ocean disposal of sediments dredged from a highly industrialized seaport. Sediments from three potential dredge sites along the Southern Branch of the Elizabeth River, Hampton Roads, Virginia were evaluated for acute toxicity to the calanoid copepod, Acartia tonsa Dana. The suspended particulate fractions of dredged materials were tested in a series of 96-hour, static bioassays. Significant mortalities were observed for all three sites with the sediments from mortality. Analysis of results indicates that mortality was correlated with the total volatile residue portion of the suspended particulate load and to site-specific factors. Potential effects on the copepod community were evaluated in reference to dispersal of suspended particulates in the open ocean.
