Comments by Lynn L. Bergeson Featured in Bloomberg Environment Article “EPA Ruling Could Allow Controversial Nanoparticles in Pesticides”

The ACTA Group

On March 23, 2020, comments by Lynn L. Bergeson, Managing Partner, Bergeson & Campbell, P.C. (B&C®) were featured by Bloomberg Environment regarding a proposed registration for Polyguard, which uses nanosilver particles to protect textiles from microbes and bacteria.

Lynn Bergeson, managing partner of Bergeson & Campbell P.C., said Polyguard’s registration application is much more targeted, for use only on textiles.

“It’s also formulated differently, it’s not in a liquid suspension (like NSPW-L30SS), it’s in the form of a plastic bead or pellet,” she said.

Bergeson said nanosilver is already used in a number of consumer products including washing machines, refrigerators, and devices used to disinfect drinking water or swimming pools.

It’s unclear what, if any, environmental regulation such products need. The EPA in 2018 outlined its plan for evaluating whether some existing registered products are actually nanosilver products and, if so, what new requirements those products may need to meet under FIFRA.

“There are many other currently registered products containing elemental particulate silver that arguably meet EPA’s definition of a nanoscale material,” Bergeson said. “But these products haven’t been reclassified as nanosilver at this time.”
