A: Pyrethroid insecticides, B: organophosphate and organochlorine insecticides. RTL = regulatory threshold level for surface water; RTL values were obtained from ^aHamilton et al. 2003, ^bCCME 2008, ^cUS EPA 1987; ND = not detected; letters A, B, C, D, E, F, and H represents the breeding sites where water and larvae were collected.
