ENVIRONMENTAL FATE
Ziram's production and use as a rubber accelerator and biocide in water treatment, paper sizing, and adhesives may result in its release to the environment through various waste streams; it's use as an agricultural fungicide will result in its direct release to the environment. If released to air, a vapor pressure of 7.510-9 mm Hg at 0 deg C, indicates ziram will exist solely in the particulate phase in the ambient atmosphere. Particulate-phase ziram will be removed from the atmosphere by wet and dry deposition. If released to soil, ziram is expected to have slight to moderate mobility in soil based on Rf values ranging from 0.33 to 0.62. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 6.210-10 atm-cu m/mole. Under acidic conditions, dimethyldithiocarbamates readily decompose to form carbon disulfide and dimethylamine. Biodegradation in soil environments may occur as the compound ionizes to form dimethyldithiocarbamate ions that biodegrade in soil; a %CO2 evolution of 68-79 after 49 days has been reported. Ziram possesses antibacterial properties, particularly for gram positive organisms, which would hinder biodegradation under many situations. If released into water, ziram is expected to adsorb to suspended solids and sediment based upon Rf values ranging from 0.33 to 0.62, retardation factors derived using soil column studies. Volatilization from water surfaces is not expected based upon the estimated Henry's Law constant. A BCF range of 5-90 suggests bioconcentration in aquatic organisms is low to moderate. Ziram undergoes hydrolysis in the environment with half-lives in water of 2 to 18 days. Occupational exposure to ziram may occur through inhalation and dermal contact with this compound at workplaces where ziram is produced or used. (SRC)
