Environmental Fate - Ecotoxicology - Human Health - A to Z Index - Home

SUMMARY

Calciferol is a rodenticide that is not approved for use in the EU. It has a moderate aquatic solubility and is non-mobile. There are considerable gaps in reported data for environmental fate and ecotoxicity. It is known to be highly toxic to mammals and is a recognised irritant.
