(Also known as: alanap; naptalam-sodium; naphthalam)
Naptalam is a herbicide without EU approval for use. It is usually used as the sodium salt as this is more soluble. Whilst naptalam is not particularly toxic to humans its major metabolite 1-naphthylamine is a carcinogen. Its environmental fate is pH sensitive. It may pose a threat to groundwaters. Virtually non toxic to mammals, birds, honeybees and most aquatic species. No data for eathworms has been identified.
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement.
Environmental fate High alert: GUS: High leachability; Drainflow: Mobile
Warning: Significant data are missing
Ecotoxicity Moderate alert: Fish acute ecotoxicity: Moderate
Human health Moderate alert: Mammals acute toxicity: Moderate; Possible Reproduction/development effects
A pre-emergence herbicide used for the control of a wide range of weeds and grasses in food and non-food crops
