- •
Permethrin rapidly degraded on concrete and formed 3-phenoxybenzoic acid (3-PBA).
- •
The main degradates of fipronil on concrete were fipronil desulfinyl and sulfone.
- •
Permethrin and fipronil degradates were found on concrete and in the runoff water.
- •
Both permethrin and fipronil degradates have toxicities to non-target organisms.
- •
The study revealed the active role of urban pavement in life cycling of pesticides.
