文摘
- •
The most important sources of fipronil in the environment have yet to be determined.
- •
Sampling was conducted to learn more about the origins of fipronil in surface water.
- •
High resolution mass spec analysis indicated that fipronil was routinely present.
- •
Concentrations were substantially elevated near wastewater treatment plant outfalls.
- •
In recycled water fipronil compounds are oxidized to a novel species.
