Species: Mallard duck (Anas platyrhynchos)
Chemical Toxicity Endpoint Type Endpoint Description Endpoint Value Sample Size Life Cycle Stage Study Duration Type
BORIC ACID TOX-REPRO - reproductive success % hatching success in fertile eggs and productivity per female (mean # of 21 d old ducklings) decrease @ 1000 ppm 15/sex/dose Adult 3 wks (pre-breeding) + breeding period to 21 d post-hatch Toxicity Factor Datasets
BORIC ACID TOX-REPRO - physiology eggshell thickness and Ratcliffe index of eggshell quality no effect 15/dose Adult 3 wks (pre-breeding) + breeding period to 21 d post-hatch Toxicity Factor Datasets
BORIC ACID TOX-REPRO - development % embryo mortality (day 15 to hatch) and duckling mortality (hatch to day 7) increase @ 1000 ppm 11-23/dose Both Adults and Juveniles 3 wks (pre-breeding) + breeding period to 21 d post-hatch Toxicity Factor Datasets
BORIC ACID TOX-REPRO - development body weight of hatchlings, compared to controls decrease @ 300, 1000 ppm 11-23/dose Hatchling 3 wks (pre-breeding) + breeding period to 21 d post-hatch Toxicity Factor Datasets
BORIC ACID TOX-Non-Repro-Sublethal - whole animal hatchling weight gain over 21 d, compared to controls decrease @ 30, 300, 1000 ppm 11-23/dose Hatchling 3 wks (pre-breeding) + breeding period to 21 d post-hatch Toxicity Factor Datasets
