Persistence and degradability
Biodegradation of monolinuron in activated sludge resulted in a 0.9% loss of the initial concentration after 5 days(1). Monolinuron, dissolved in acetone/water and sprayed onto ground waste (compost), was demethylated in small amounts (0.4% of the extracted radioactivity) after 3 weeks to N-methoxy-N'-4-chlorophenyl-urea, whereas 86.2% of the extractable radioactivity was unaffected started material(2). A mixed bacterial culture (containing Gram-negative aerobic rods and Gram-positive aerobic non-spore-forming rods, and cocco-bacilli) from soil (sandy loam) was able to degrade monolinuron completely after 10 days(3).
Bioaccumulative potential
Bioaccumulation tests using activated sludge, algae, and fish (golden ide) gave BCF values for monolinuron of 70 (5-day), 40 (1-day), and 20 (3-day), respectively(1). The BCF for monolinuron has been estimated to be 17 and 10 based on water solubility and Koc, respectively(2). Another BCF value monolinuron was calculated to be 22(3). The experimental BCF value of monolinuron in the algae Chloroella was 33 after exposure to 50 ug/l for 24 hours(4). The BCF value for monolinuron in fish (golden orfe) and algae (Chlorella Fusca) were experimentally determined to be <20 (3-day at 45 ug/l) and 60 and 140 (24 hours at 50 ug/l), respectively(5). According to a recommended classification scheme(6), the experimental BCF values suggest that monolinuron should undergo moderate to high bioconcentration in aquatic organisms(SRC).
Mobility in soil
The Koc for monolinuron has been estimated and experimentally determined to be 200(1,4). The Koc for monolinuron has also been experimentally determined to be 69.2(2). An average Koc value has been reported to be 40 in soils with organic carbon contents ranging from 0.58-2.3%(3). The Koc for monolinuron has been determined to be 60.3(5). The Koc values determined for monolinuron ranged from 211 to 2025 with an average of 517 in eight Czechoslovakian soils with organic matter contents ranging from 0.1-4.6%(6). The average Koc value for monolinuron in 10 different soils was determined to be 271.5(7). Another average Koc value has been determined to be 60(8). According to a recommended classification scheme(9), these Koc values suggest that monolinuron should have slight to very high mobility in soil(SRC).
Other adverse effects

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.
