ABSTRACT
Embryotoxicity of the oil dispersant Corexit 9500 was examined using fertilized mallard duck eggs. Corexit 9500 was topically applied below the air cell to eggs in volumes ranging from 0 to 100 µL on day 3 of incubation. The highest incidence of mortality occurred at developmental stage 4, one day post-Corexit 9500 application. Hatching success was significantly decreased among eggs treated with ≥ 20 µL of Corexit 9500 as compared to controls (P ≤ 0.047). No egg treated with ≥ 40 µL successfully hatched. The application volume resulting in 50% mortality (corrected for control survival) was determined to be 15.5 µL. Developmental stage at embryo death was also significantly decreased compared to controls in eggs exposed to 40 µL (P = 0.0042) and above.
