| FIFRA 要件 | As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their future use. Under this pesticide reregistration program, EPA examines health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether they are eligible for reregistration. In addition, all pesticides must meet the new safety standard of the Food Quality Protection Act of 1996. Linuron is found on List A, which contains most food use pesticides and consists of the 194 chemical cases (or 350 individual active ingredients) for which EPA issued registration standards prior to FIFRA, as amended in 1988. Case No: 0047Pesticide type: herbicideRegistration Standard Date: 06/29/84Case Status: RED Approved 12/94OPP has made a decision that some/all uses of the pesticide are eligible for reregistration, as reflected in a Reregistration Eligibility Decision (RED) document.Active ingredient (AI):LinuronData Call-in (DCI) Date(s): 09/04/90, 11/08/93, 04/28/95AI Status: OPP has completed a Reregistration Eligibility Decision (RED) document for the case/AI.Tolerances are established for residues of the herbicide linuron (3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea) in or on the following food commodities: asparaguscarrotscattle, fatcattle, mbypcattle, meatcelerycorn, field, foddercorn, field, foragecorn, fresh (inc. sweet K+CWHR)corn, grain (inc. pop)corn, sweet, foddercorn, sweet, foragecottonseedgoats, fatgoats, mbypgoats, meathogs, fathogs, mbyphogs, meathorses, fathorses, mbyphorses, meatparsnips (with or without tops)potatoessheep, fatsheep, mbypsheep, meatsorghum, foddersorghum, foragesorghum, grain (milo)soybeans (dry and succulent)soybeans, foragesoybeans, haywheat, foragewheat, grainwheat, hayand wheat, straw.Tolerances with regional registration, as defined in 180.1(n), are established for residues of the herbicide linuron 3-(3,4- dichlorophenyl)-1-methoxy-1-methylurea in or on the following food commodity: parsley. |

| 処分方法 | SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.Linuron should be incinerated in a unit operating at 850 °C equipped with offgas scrubbing equipment. ... Recommendable methods: Incineration. |
| 漏出処分 | Do NOT wash away into sewer. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Personal protection: self-contained breathing apparatus. |
| Preventive Measures | AVOID BREATHING DUST OR SPRAY MIST. AVOID CONTACT WITH SKIN, EYES, & CLOTHING.Wash contaminated clothing with soap & hot water before re-use.Avoid contact with skin, eyes, and clothing. ... Keep out of lakes, streams, or ponds.SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place. |

| 環境中動態 | TERRESTRIAL FATE: Based on a classification scheme(1), a Koc value ranging from 555 to 987(2), indicates that linuron is expected to have low mobility in soil(SRC). Volatilization of linuron from moist soil surfaces is not expected to be an important fate process(SRC) given an experimental Henry's Law constant of 1.97X10-9 atm-cu m/mol(3). Linuron is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure of 1.43X10-6 mmHg(4). The dissipation of linuron was followed in field plots planted with potatoes and treated at 1 and 2 kg/ha(5). The disappearance of linuron was very fast and followed first-order kinetics with a half-life of 25 and 22 days, respectively, at the two application rates. After about 75 days, the residual concentration of linuron in the soil was constant, suggesting that a small amount of linuron is strongly absorbed to soil colloids and not available to microbial attack(5). Most evidence indicates that linuron's loss in soil is due to biodegradation(6). For example linuron, at 4 ppm, degraded with half-lives of 22-86 days when incubated at 25 °C in 18 mineral soils(7). Photolysis of linuron on surface soils may also be an important degradation pathway. Phenyl-labeled C-14 linuron degraded with a half-life >15 days on silt loam soil irradiated continuously with a Pyrex glass filtered xenon arc light at 25 deg(8). After 15 days of irradiation, the soil contained 78.8% of the recovered radioactivity as parent linuron.TERRESTRIAL FATE: The half-life of linuron in cropped fields was 8-25 weeksresidues were undetectable after 6 mo(1-2). No progressive buildup was observed after repeated treatment(1-2). Four weeks after a half normal, normal, and double normal spray of linuron in May on corn, carrots, bean and potato crops planted in loamy soil, an average of 40% of the applied dose was recovered(3). After 3 months, only 25% of the linuron was recovered(3). At the end of the winter months, <0.4% of the linuron was recovered(3). In Greenhouse experiments linuron's persistence was 25-60 weeks(3). In test field plots in a vegetable growing area of Ontario, 64% of linuron had dissipated in 5 months from the organic soil (92% organic matter)(4). It was concluded that linuron residues did not accumulate in soil in vegetable farms of area growers(4).AQUATIC FATE: Based on a classification scheme(1), an experimental Koc value ranging from 555 to 987(2), indicates that linuron is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon a Henry's Law constant of 1.97X10-9 atm-cu m/mole(4). According to a classification scheme(5), a BCF ranging from 13 to 49(6,7), suggests the potential for bioconcentration in aquatic organisms is low to moderate. Hydrolysis of linuron is not expected to occur in water except at high alkaline conditions (pH> 9)(8). There was no evidence of hydrolysis products after 4 months in buffered solutions at pH 5, 7, and 9(8). Biodegradation of linuron in surface waters appears to be site specific. Although linuron did not biodegrade when incubated with river water and sewage for 4 months(8), when it was applied as an emulsifiable formulation to ditch water, it degraded with half-lives ranging from 7.2 to 11.8 days during the stagnant period (1 week), and an average half-life of 3.8 days during the flow period (3 weeks)(9). Disappearance of linuron was slower in the higher treatment rate ditches, and in those studied during lower temperature periods(9). Photolysis of linuron is expected to occur in surface waters. In one experiment, 43% of linuron exposed to sunlight outdoors was photolyzed in 24 days(8). After 1 ppm of linuron was added to each of three 1 cu m outdoor ecosystems, linuron concns in the water columns declined exponentially over the 42-day experimentthe calculated half-lives ranged from 16 to 42 days(10). The half-life of linuron in Lake Balatan (Hungary) water was 10 weeks(11).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semi-volatile organic compounds in the atmosphere(1), linuron, which has a vapor pressure of 1.43X10-6 mm Hg at 25 °C(2), is expected to exist in both the vapor and particulate phase in the ambient atmosphere. Vapor-phase linuron is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 12 hours(SRC), calculated from its rate constant of 1.0X10-11 cu cm/molecule-sec at 25 °C determined using a structure estimation method(3). Particulate-phase linuron may be removed from the air by wet and dry deposition(SRC). Linuron may undergo photolysis in air based upon its absorption maximas at 210, 245, and 280 nm with some overlap at > 290 nm(4). The rate of photolysis in the environment appears to be slow. Phenyl-labeled C-14 linuron degraded with a half-life > 30 days in sterile aqueous pH 5 buffer solution irradiated with natural sunlight at 25 °C(4). |
| 食品調査値 | Of the 1044 composites analyzed in the FDA Adult Total Diet Study in FY1978-82, 19 contained linuron(1). In the FY1978-82 FDA'S Adult Total Diet Study Survey, the mean concn of linuron in root vegetable composites was 0.0089 ppm(2). Linuron dietary intakes estimated from the July 1986-April 1991 FDA Total Diet Study were 0.0018 ug/kg body wgt/day for a 6-11 month old0.0024 ug/kg body wgt/day for 2 yr oldand ranged from 0.0005 to 0.0008 ug/kg body wgt/day for respective groups of 14-16 yr, 25-30 yr, and 60-65 yr males and females (3). In a pesticide screening survey of 6970 produce samples, linuron was detected in 226 carrot samples (detection limit = 0.2 ppm)all of the samples containing linuron were carrots(4). Of the 6,568 samples of domestic food and feed the FDA analyzed between 1982 and 1986, 30 (29 of them carrots) contained linuron with levels up to 0.5 ppm(5). None of the 13,283 imported agricultural commodities tested contained linuron(5). No linuron residues (detection limit = 0.1 ppm) were found in 13 potatoes from farms in NJ, 9 from FL, and 3 from CA(6). In a 1994 surveillance study of domestic food samples collected from the U.S. and Puerto Rico, and import food samples from 101 countries, in which 329 pesticides were monitored and only 94 were found, linuron was detected in an unspecified number of samples(7). |

| Average Daily Intake | FOOD INTAKE: Assumed 0.0010 ug/kg/d for a 70 kg 14-16 yr male(1). The intake of linuron from the FY1981/82 FDA's Adult Total Diet Study, in which the typical 14-day diet of a 16-19 yr male is collected throughout the US from market basket composite samples in 12 food groups, was 0.004 ug/kg body wt/day(2). An analogous FY 81/82 study for infants and toddlers determined the daily intake of linuron to be 0 and 0.001 ug/kg body wt/day for infants and toddlers, respectively(3). The daily intake of linuron for 6-11 month infants, 2-yr toddlers, 14-16 yr males and 60-65 yr females according to the 1982-1984 FDA Total Diet Study was 0.0010, 0.0014, 0.0004, 0.0005 ug/kg body wt/day, respectively(4). The major source of linuron was carrots(4). Linuron intakes estimated from the 1990 FDA Total Diet Study were 0.0027, 0.0010, and 0.0012 ug/kg/day for a 6-11 month old, a 14-16 yr male, and a 60-65 yr female, respectively(1).

用途
説明
Linuron is found as white crystals that have no smell. It is very slightly soluble in water. Linuron can enter the body either by ingestion of contaminated food or water or by dermal contact. Linuron can cause nausea, vomiting, and diarrhea. Eye contact can cause irritation. There is little evidence available as to the effects of exposure to linuron on human health. However, exposure to linuron at normal background levels is unlikely to have any adverse effect on human health.
使用
Linuron is used to control annual and perennial broadleaf and grassy weeds on crop and noncrop sites. It is used as a pre- and post-emergent herbicide. It works by inhibiting photosynthesis in target weed plants. It is used in soybean, cotton, potato, corn, bean, pea, winter wheat, asparagus, carrot, and fruit crops. It is also used on crops stored in warehouses and storerooms. Linuron is classified by the US Environmental Protection Agency (EPA) as a Restricted Use Pesticide (RUP).
一般的な説明
Colorless crystals. Non corrosive. Used as an herbicide.
