Australia
- 2002: There are chemicals under consideration (or reconsideration)
or being evaluated for use as
termiticides in
Australia that are currently used with varying success in other
countries. One of the more interest ing variations is Silafluofen
(C25H29FO2Si), an insecticide (pyrethroid
ether) containing silicon, used
in Japan for soil and timber treatments against termites and
other pests since 1991. It has
become popular because it has low toxicity to fish and mammals,
and it is highly stable chemically (Nakayama et al., 2001).
Antitermitic plastic sheeting and antitermitic heat insulators
have been developed by impregnating
silafluofen into plastic film and
polystyrene foam.

of the Community Strategy for Endocrine Disruptors - a
range of substances suspected of interfering with the hormone
systems of humans and wildlife. Communication from the Commission
to the Council and the European Parliament. Commission of
the European Communities, Brussels COM (2001) 262 final. This
document presents a "priority list of substances for
further evaluation of their role in endocrine disruption.
During 2000, a candidate list of 553 man-made substances and
9 synthetic/natural hormones has been identified."
Categories
included on the Endocrine Disruptor List |
Synthetic
pyrethroids |
While
only the broad category "Synthetic pyrethroids" was
included in the Commission's list, it might be of some interest
to note that the following organofluorine pesticides are "Synthetic
pyrethroids:" Acrinathrin, Bifenthrin,
beta-Cyfluthrin, Cyhalothrin, gamma-Cyhalothrin, lambda-Cyhalothrin,
Fenfluthrin, Flucythrinate, Flufenprox, Flumethrin, Fluvalinate,
tau-Fluvalinate, Halfenprox, Protrifenbute, Silafluofen,
Tefluthrin, Transfluthrin |
