Persistence and degradability
Investigators/ ... were able to isolate from brookston silty clay loam a bacterium of genus pseudomonas which utilized monuron as sole source of carbon.
Bioaccumulative potential
From its water solubility and a regression equation, the bioconcentration factor (BCF) for monuron in aquatic organisms has been estimated to be 29(1). Based on a log Kow value of 1.94(2) and a regression equation(3), the BCF value can be estimated to be 17(SRC). Both these values indicate that bioconcentration of monuron in aquatic organisms should not be important(1,SRC). The low rate of uptake and fast depuration (depuration half-life of 0.45 days) of monuron from catfish (Ictalurus melas)(4) also indicates that bioconcentration will not be important(SRC).
Mobility in soil
The Koc values for monuron determined from experimental adsorption isotherms or estimated using recommended regression equations range from 83 to 225(1-6). According to a suggested classification scheme(9), Koc values of this magnitude indicate that monuron is moderately to highly mobile in soil. Soil thin layer chromatographic studies also indicate that monuron is moderately mobile in soil(5,7). The adsorption of monuron in soil is virtually independent of pH and clay content of soil, but the adsorption increases with increase in organic carbon content(6,8). However, other investigators concluded that the adsorption of monuron increases with an increase in the clay content of soil(10).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
