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.
