Because of increasing global concern over the consequences of marine and aquatic pollution, a separate volume addressing this subject was added to the ASFA series. ASFA 3 is the only abstracts journal devoted exclusively to research and policy on the contamination of oceans, seas, lakes, rivers, and estuaries. ASFA 3 contains information that will prove essential to specialists who deal in any capacity with aquatic environments and marine pollution problems, including biologists, oceanographers, limnologists, environmental engineers and scientists, industrial engineers, waste managers, corporate regulatory affairs managers, and government officials.

Abstract
The insect growth regulator diflubenzuron (DFB) may have substantial
effects on non-target organisms, especially crustaceans. By targeting
the moulting process, DFB would be expected to elicit the most
obvious effects on subadult crustaceans which moult frequently.
Previous studies in this laboratory have demonstrated acute and
chronic effects of DFB on survival and development of nauplii
of the estuarine copepod Eurytemora affinis at water concentrations
of less than 1 p.p.b. The present study examines the effects on
maturation to adulthood and brood production. Effects on brood
production were observed at 0.8 p.p.b. DFB in individuals exposed
only during the copepodite stages. Significant effects on production
of nauplii were documented only in the early exposure to 0.93
p.p.b. DFB. Inability of post-moult copepodites to completely
cast exuviae also was documented in the exposed treatments. At
salinities of 2, 10 and 15 p.p.t., survival from naupliar to adult
stages was significantly reduced at 0.84 p.p.b. and none survived
to adulthood at 1.7 p.p.b. These results suggest that DFB has
substantial effects on survival and development of E. affinis
at a water concentration of less than 1 p.p.b. DFB concentrations
exceeding this concentration have been reported from Chesapeake
Bay surface waters although there is no current evidence of potentially
toxic concentrations overlapping with the known distribution of
E. affinis in the bay. |
