ASFA 3: Aquatic
Pollution and Environmental Quality
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.
