Popular Insecticide Detected In Suburban Stream Beds

Researchers announced they have detected high concentrations of a =
popular
insecticide in suburban stream sediments, raising concerns about its =
effects
on aquatic life.

Pyrethroids, the active ingredient used in most home and garden =
insecticides,
have been on the market for years. Although the compounds are considered
potentially less harmful to humans than other insecticides, surprisingly
little information is available about their long-term impact on the
environment, according to Donald Weston, Ph.D., an adjunct professor of
ecotoxicology at the University of California, Berkeley.

The finding, by Weston and others, was published online Oct. 19 by the
American Chemical Society's journal, Environmental Science & Technology. =
A
print version of the article is scheduled to appear in the journal's =
Dec. 1
issue.

Nearly all of the sediment samples Weston and his colleagues gathered =
from
streams bordering a Roseville, Calif., neighborhood (a suburb of =
Sacramento)
contained enough pyrethroids to eradicate a small bottom-dwelling =
crustacean
called Hyalella azteca.

"These results indicate that monitoring for pyrethroids in urban and =
suburban
streams is overdue, and the public, regulators, and the scientific =
community
should give greater consideration to the potential effects of =
residential use
of pyrethroids on aquatic systems," Weston and his colleagues conclude.
