POVZETEK

2,4-D is a selective, systemic herbicide approved for use in the EU and used for the control of broad-leaved weeds. It is highly soluble in water, volatile and has a low potential to leach to groundwater based on its chemical properties. It is non-persistent in soil but may persist in aquatic systems under certain conditions. It is moderately toxic to mammals but should not bioaccumulate. It may have negeative effects on reproduction, development and is considered to be a neurotoxin and an irritant. It is moderately toxic to birds and most aquatic species as well as honeybees and earthworms.
