Abstract
The chronic aquatic toxicities of a microbicide dibromonitrilopropionamide (DBNPA) in Daphnia magna and rainbow trout were evaluated. DBNPA can significantly affect the reproduction and survival of D. magna. The lowest observed effective concentration (LOEC) and the no observed effective concentration (NOEC) of DBNPA to D. magna were 0.053 and 0.072 mg L(-1), respectively, and the intrinsic rate of natural increase (r) was significantly decreased (p < 0.05) at a concentration of 0.01 mg L(-1). Meanwhile, DBNPA affected the growth of juvenile rainbow trout at a concentration of 0.01875 mg L(-1) after 28-day exposure. The results showed that DBNPA has chronic deleterious effects on aquatic organisms.
