Likely to generate heat spontaneously upon exposure to air or water. May be sufficient to ignite the material. Maneb is used as a fungicide. Formulations of Maneb include mixing it with many other chemicals such as sulfur, zinc oxide and others to desensitize it. This is done to make it easer for application. Source: CAMEO Chemicals

- Environmental Bioconcentration: In a 3-day static system study, a BCF for maneb of <10 was measured in golden ide (Leuciscus idus melanotus) fish(1). According to a classification scheme(2), this BCF suggests bioconcentration in aquatic organisms is low. Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), a Koc value of 240(2) indicates that maneb is expected to have moderate mobility in soil(SRC). Volatilization from moist soil surfaces is not expected to be an important fate process based upon rapid degradation of maneb in the environment by hydrolysis, oxidation, and photolysis, although microbial degradation may also contribute to soil transformation(3). Maneb is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 7.5X10-8 mm Hg(2). Aqueous solutions of maneb absorb UV light in the spectrum between 290 and 360 nm(4) which indicates a potential for direct photolysis from moist soil and plant surfaces(SRC). In a 5-day CO2 evolution study using an activated sludge inoculum, 0.6% of applied maneb was detected as 14C-labeled CO2(4), suggesting biodegradation may occur in soil(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), a Koc value of 240(2) indicates that maneb is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected based upon rapid degradation of maneb in the environment by hydrolysis, oxidation, and photolysis, although microbial degradation may also contribute to soil transformation(3). According to a classification scheme(4), a BCF of <10, measured in golden ide (Leuciscus idus melanotus) fish(5), suggests bioconcentration in aquatic organisms is low(SRC). Hydrolytic decomposition depends upon the aeration of the water and the pH with faster decomposition in aerated water and with increasing acidity(6). Aqueous solutions of maneb absorb UV light in the spectrum between 290 and 360 nm(5) which indicates a potential for direct photolysis in sunlit water(SRC). 14C-maneb was degraded 9.73-16.18% after 67 days in July and 11.18-27.37% in Sept in sediment at 5 sites from a Nicaraguan estuary incubated under anaerobic conditions(7). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), maneb, which has a vapor pressure of 7.5X10-8 mm Hg at 20 °C(2), is expected to exist solely in the particulate phase in the ambient atmosphere. Particulate-phase maneb may be removed from the air by wet or dry deposition(SRC). Aqueous solutions of maneb absorb UV light in the spectrum between 290 and 360 nm(3) and this indicates a potential for direct photolysis in the environment(SRC).
