Absorption, Distribution and Excretion
/In a rat metabolism study/... Preliminary study: Group A, 2 male (M)/2 female (F) exposed to a single oral dose of [14C]fluridone (...radiopurity 99.8%; for test solutions [14C]fluridone was mixed w/[12C]fluridone, ...100% purity; test substance was suspended in 1% sodium carboxymethyl cellulose [CMC]) at ~10 mg/kg. Group B, 1M/1F exposed to a single oral dose at ~1000 mg/kg. Urine, feces and cage rinses were collected daily for 7 days (because expired (trapped) 14CO2 accounted for <1% of the dose after 24 hr, further 14CO2 measurements were discontinued). Definitive study: Group C, vehicle controls, 2M/2F exposed to a single oral dose of 1% CMC. Group D, 5M/5F exposed to a single oral dose at ~7.4 mg/kg. Group E, 7M/7F exposed to ~10 mg/kg unlabeled fluridone once daily for 14 days, then 5M/5F exposed on day 15 to ~10 mg/kg [14C]fluridone. Group F, 5M/5F exposed to a single oral dose at ~900 mg/kg. ...Clinical signs (lack of mobility, abnormal and rapid head movement, squinting, loss of balance and cage biting) occurred only at the HD (Groups B and F), clearing within 24 hr. Results, Group A: by 7 days, 12.52%/12.89% (M/F) was excreted in urine and 72.76%/81.79% in feces. Group B: by 7 days 4.83%/3.43% was excreted in urine and 86.43%/86.31% in feces. Group D: by 24 hr 11.14%/10.44% was excreted in urine and 72.46%/77.72% in feces. By 7 days 11.61%/10.93% was excreted in urine and 79.19%/84.62% in feces. Combined excretion (including cage rinse) by 7 days was 92.93%/98.74%. Group E: by 24 hr 9.54%/8.51% was excreted in urine and 70.69%/69.90% in feces. By 7 days 10.11%/9.14% was excreted in urine and 79.80%/81.79% in feces. Combined excretion (including cage rinse) by 7 days was 92.81%/94.21%. Group F: by 24 hr 2.40%/2.43% was excreted in urine and 27.16%/27.18% in feces (thus, a relative delay in fecal excretion at the HD). By 7 days 8.30%/8.07% was excreted in urine and 91.58%/90.09% in feces. Combined excretion (including cage rinse) by 7 days was 101.02%/99.62%. Total tissue residues were always <1% of the dose (Groups D-F). Under all conditions, highest tissue levels occurred in the liver. The major metabolites were a variety of polar and non-polar compounds resulting from aromatic hydroxylations and heteroaromatic N-demethylation. The parent compound was the primary fecal component over the 1st 72 hr.

12.2 Persistence and degradability
AEROBIC: A half-life of 12 months was reported for fluridone in sediment under laboratory conditions and 17 weeks under field conditions(1). Fluridone was reported to dissipate with average half-lives of 20 days and 3 months in pond water and in pond hydrosoil, respectively(2). A half-life of 4 days was observed for fluridone after treatment in a pond(3). A half-life of 1 year or more was observed for fluridone in hydrosoils(3). Photodegradation was found to be the major degradation pathway of fluridone in aquatic systems under actual-use conditions(1). In field studies using different soil types, <10% of the originally applied fluridone was found after 220 days in Miller clay and 20% was found remaining after 385 days in Lufkin fine sandy loam soil(4). In laboratory studies, fluridone persistence in non-sterilized soils after 210 days was 62, 44, 10, and 5% in Lufkin fine sandy loam, Miller clay, Hidalgo sandy clay loam, and Brennan fine sandy loam, respectively(4). In Miller clay and Lufkin fine sandy loam no difference was observed in the rate of fluridone degradation between sterilized and non-sterilized samples; however, noticeable differences in degradation were observed between sterilized and non-sterilized Brennan fine sandy loam and Hidalgo sandy clay loam(4). A half-life of 360 days was reported in aerobic soil(5).
12.3 Bioaccumulative potential
BCF values ranging from 0 to 91 have been reported for fluridone in various fish(1-4). According to a classification scheme(5), BCF values of <30 are low, and from 30 to 100 are moderate.
12.4 Mobility in soil
Koc values for fluridone measured in 6 soils were reported to range from 350 to 2,462(1-3). According to a classification scheme(4), these Koc values suggest that fluridone is expected to have low to slight mobility in soil. The pKa of fluridone is 12.3(5), indicating that this compound will primarily exist in the protonated form in the environment and cations generally adsorb more strongly to organic carbon and clay than their neutral counterparts(6).
12.5 Other adverse effects
no data available
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.
