Maneb is a fungicide and a polymeric complex of manganese with the ethylene bis(dithiocarbamate) anionic ligand.[1]

Health effects

[edit]

Exposure to Maneb can irritate the eyes, nose, and throat. Prolonged or long-term exposure may interfere with the function of the thyroid.[2]

Production

[edit]

Applications

[edit]

It can be also used to create a toxin-based animal model of Parkinson's disease, usually in primates.[3]

Regulation
