12.2 Persistence and degradability
Most evidence indicates that linuron's loss in soil is due to biodegradation(1-2). Biodegradation is mainly cometabolic(1-2). Evidence for linuron's biodegradation in soil is found in the fact that degradation proceeds far slower in soil sterilized by heat or with chemicals(1). Loss of linuron also correlates with soil respiration(3). The degradation rate also is correlated with soil organic carbon content, adsorptivity and clay content(1,3). The rate of biodegradation increases as the concn of linuron in the soil decreases(4). The rate constant for the decomposition in soil increases as the square root of the concn at high concns and linear with the concn at low concns(2). At higher soil moistures and temperatures, linuron degrades faster(1,5). In most soils, at normal application rates, linuron degrades within 3-4 months(1). The half-lives of 4 ppm linuron incubated at 25°C in 18 mineral soils ranged from 22 to 86 days(5). The degradation rate of linuron in a sandy loam soil at 20°C was 0.0080 per day (half-life 87 days)(3).
12.3 Bioaccumulative potential
Linuron residues accumulated in bluegill fish during 28 days of exposure to water treated at 0.1 and 1.0 ppm [C14] linuron(1). Maximum bioconcentration factors were 49 for whole fish, 34 for a muscle and 39 for carcass tissues. After 28 days of exposure, linuron residues in the viscera were identified as desmethyl linuron, norlinuron, and glucuronide conjugates. The edible tissues were not analyzed for linuron residues. Residues rapidly declined to approximately 10% of maximum levels after the 14-day depuration period(1). In one bioaccumulation study, orange-red killifish were exposed to 0.02 to 0.2 mg/l of linuron for 28 days(2). At the end of the experiment, the BCF of linuron in the fish ranged from 13 to 23. According to a classification scheme(3), BCF values ranging from 13 to 49 suggest the potential for bioconcentration in aquatic organisms ranges from low to moderate.
12.4 Mobility in soil
ADSORPTION INCR AS CLAY CONTENT &/OR ORG MATTER CONTENT OF SOIL INCR; CLAYS OF HIGH /CATION/ EXCHANGE CAPACITY ABSORB MORE LINURON THAN THOSE OF LOW EXCHANGE CAPACITY. ... LEACHING IS NOT BELIEVED TO BE AN IMPORTANT FACTOR IN DISAPPEARANCE FROM MOST SOILS.
12.5 Other adverse effects

13.Disposal considerations
13.1 Disposal methods
Product
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.
Contaminated packaging
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.
