NOMENCLATURE

Common name mancozeb (BSI, E-ISO); mancoze ((m) F-ISO); manzeb (JMAF)

IUPAC name manganese ethylenebis(dithiocarbamate) (polymeric) complex with zinc salt  

Chemical Abstracts name [[1,*-ethanediylbis[carbamodithioato]](*-)]manganese mixture with [[1,*-ethanediylbis[carbamodithioato]](*-)]zinc  

CAS RN [********7] (formerly [********6]); number also applies to other mixed manganese and zinc ethylenebis(dithiocarbamate) complexes  

PHYSICAL CHEMISTRY

Composition The ISO definition is 'a complex of zinc and maneb containing *0% of manganese and 2.*5% of zinc, the salt present being stated (for instance mancozeb chloride)'. A manufacturer gives the ratio of maneb to zinc as 1:0.**1, i.e. *0% Mn and 2.2% Zn.  Mol. wt. **1.2 (based on Composition)  M.f. [C4H6MnN2S4]xZny  Form Greyish-yellow, free flowing powder with a slight odour of hydrogen sulfide.  M.p. Decomposes at **2    V.p. ***0 mg/kg soil; *6 d reproduction NOEC for Eisenia foetida *0 mg/kg soil.  

ENVIRONMENTAL FATE

EHC *8 (WHO, ***8; general review of dithiocarbamates).  Mancozeb breaks down rapidly in soil, sediment and water; terminal metabolites are natural products and with mineralisation to carbon dioxide. It does not bioaccumulate.  Animals Poorly absorbed and rapidly excreted in animals. The spectrum of metabolites produced was similar in laboratory and farm animals, pointing to two common metabolic pathways, which both lead ultimately to the formation of glycine and to incorporation of the metabolites into natural products.  Plants Extensively metabolised in plants, forming ethylenethiourea, ethylenethiuram monosulfide, ethylenethiuram disulfide, and sulfur as transitory intermediates. Terminal metabolites are natural products, especially those derived from glycine.  Soil/Environment Rapidly degraded in the environment by hydrolysis, oxidation, photolysis, and metabolism. Soil DT*0 <1 d (ave., *0  ). Koc ***0 ml/g.
