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


Aldicarb is an insecticide that is not approved for use in the EU. It is highly soluble and volatile. It is not persistent in soil but may be in in aqueous sustems. It is highly toxic to humans but has a low potential to bioaccumulate. It is a known endocrine disrupter, a neurotoxin and an inhibitor of acetyl cholinesterase. Aldicarb is highly toxic to birds and honeybees, and moderately toxic to most aquatic organisms and earthworms.
