/BIRDS and MAMMALS/ Ataxia, weakness, falling. Regurgitation also occurred in first 2 hr after treatment. The other signs occurred 2 to 14 days after treatment. Although no birds died, considerable wt losses had occurred by the end of the 14 day observation period. /Female mallards, acute oral/|/BIRDS and MAMMALS/ Because there are no mortalities at the highest concentration tested (LD50 greater than 2000 mg/kg, LC50 greater than 4360 ppm), benfluralin is considered to be practically non-toxic to birds on an acute and subacute basis. The likelihood of acute or subacute risk to non-endangered and endangered species of birds is low. Benfluralin caused reproductive effects in chronic avian studies. Avian reproductive toxicity was assessed in two studies that are presented in Table 11 below. The bobwhite quail endpoint cannot be assumed conservative, as effects were observed at the lowest dose tested of 96 ppm. Another quail study is needed to establish a No Observed Adverse Effect Concentration (NOAEC) for reproductive effects since a NOAEC was not established in this test. At the Lowest Observed Adverse Effect Concentration (LOAEC) the reproductive toxicity study with the Northern Bobwhite Quail, showed developmental effects that included a decrease in the number of surviving hatchlings, decreased egg set, and decrease in 14-day hatchling survivor weight. At the LOAEC, of the reproductive toxicity study with the Mallard Duck showed an increase in the percentage of eggs that cracked. Chronic risks to birds are expected from both spray and granular formulations of benfluralin ...|/AQUATIC SPECIES/ Available acute toxicity data on technical benfluralin indicate that it is very highly toxic to estuarine/marine invertebrates. The 96-hour flow-through study yielded an EC50 of 0.043 ppm a.i. and NOAEC of 16 ppb. No data are available to assess chronic toxicity endpoints for estuarine/marine fish and invertebrates.|/AQUATIC SPECIES/ Freshwater Species. The available acute toxicity data on benfluralin ... indicate that it is very highly toxic to freshwater fish on an acute basis, based on typical end-use product (TEP) LC50 values of less than 100 ppb ai in bluegill sunfish. Based on TEP data, benfluralin is moderately toxic to freshwater aquatic invertebrates on an acute basis with a daphnid LC50 of 2.18 ppm active ingredient. This study is for a formulated product ... Chronic data for freshwater fish show that growth and development was the most sensitive endpoint for benfluralin. Test results indicate that benfluralin may affect fish length and survival at concentrations greater than 1.9 ppb.|For more Ecotoxicity Excerpts (Complete) data for BENFLURALIN (6 total), please visit the HSDB record page.

Benfluralin's production may result in its release to the environment through various waste streams; it's use as a soil incorporated, pre-emergent herbicide for the control of annual grasses and some annual broad-leaved weeds will result in its direct release to the environment(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), Koc values of 9,840-11,660(2) indicate that benfluralin is expected to have no mobility in soil(SRC). Volatilization of benfluralin from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.9X10-4 atm-cu m/mole(SRC), derived from its vapor pressure of 6.6X10-5 mm Hg(3) and water solubility of 0.1 mg/L(3); however, adsorption may attenuate this process(SRC). Volatilization from dry soil surfaces is not expected(SRC) based on the vapor pressure of this compound(3). Benfluralin is metabolized with a half-life of 20 to 86 days under aerobic soil conditions and 12 days in laboratory studies under anaerobic conditions(2). Benfluralin may also be susceptible to photolysis on soil surfaces based on a half-life of 12.5 days in which benfluralin was applied to the surface of a soil and irradiated with natural sunlight(2). A biodegradation half-live range of 20 to 86 days in soil(4) suggests that biodegradation is a slow process in terrestrial environments(SRC).|WHEN SOIL TREATED WITH BENEFIN WAS FLOODED WITH WATER, BENEFIN DECOMP RAPIDLY. ONLY 4.6% WAS DETECTABLE AFTER 16 DAYS.

IDENTIFIABLE DEGRADATION PRODUCTS WERE THE DEALKYLATED, REDUCED & OXIDIZED DERIVATIVES OF BENEFIN & AN UNIDENTIFIED POLAR MIXT.|Duration of residual activity in soil is about 4-8 months.|For more Environmental Fate (Complete) data for BENFLURALIN (6 total), please visit the HSDB record page.

MATERIAL REMAINING ON THE SOIL SURFACE CAN BE SUBJECT TO PHOTODECOMPOSITION.|Degradation of benfluralin was observed when glass plates coated with soils containing benfluralin were irradiated with light of wavelength greater than 290 nm(1-2). When exposed to sunlight for 6-7 days in July, about 17-25% benfluralin photodegraded from glass plates coated with soil containing benfluralin(3-4). Therefore, photodecomposition of benfluralin from water and soil surfaces should occur(SRC).|The rate constant for the vapor-phase reaction of benfluralin with photochemically produced hydroxyl radicals has been estimated as 2.2X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 17 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). Benfluralin is stable to hydrolysis at pH 5-9(2). The aqueous photolysis half-life of benfluralin was reported as 5.5-9.9 hours and a soil photolysis study yielded a half-life of 12.5 days(3).

The whole body BCF value measured in fish was 1,580(1). According to a classification scheme(2), this BCF value suggests the potential for bioconcentration of benfluralin in aquatic organisms is very high(SRC).

1.07e+04 L/kg|Soil adsorption (Kd) coefficients for benfluralin in 10 Wisconsin soils ranged from 4.2-30.3, with a mean value of 16.7 (1). Other investigators have reported Koc values of 10,700(2), 10,715(4), and 9,000(3). Benfluralin was much more highly adsorbed to soil than other dinitroaniline herbicides(5). In soil thin layer chromatography experiments, the Rf (retention factor) range was 0-0.03 for benfluralin(6). Therefore, it was concluded that benfluralin was immobile in soil(6). In the EPA Registration Eligibility Decision document for benfluralin, it was reported that the Koc ranged from 9,840-11,660(7). According to a classification scheme(8), this range of Koc values indicates that benfluralin is expected to have no mobility in soil(SRC).

The Henry's Law constant for benfluralin is estimated as 2.9X10-4 atm-cu m/mole(SRC) derived from its vapor pressure, 6.6X10-5 mm Hg(1), and water solubility, 0.1 mg/L(1). This Henry's Law constant indicates that benfluralin is expected to volatilize from water and moist soil surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 5 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 9 days(SRC). Volatilization may be attenuated due to adsorption(SRC). The volatilization half-life from a model pond was estimated as 136 days when adsorption was considered(3). Volatilization from dry soil surfaces is not expected(SRC) based on the vapor pressure(1). Benfluralin applied at a rate of 1.68 kg/ha to the surface of a Lakeland sand (89% sand, 5% silt, 6% clay, pH 5.9) volatilized 3, 12 and 25% within 3 hours at temperatures of 30, 40, and 50 °C, respectively at a soil moisture of 7%(4). At a soil moisture of 15.3%, volatilization losses in 3 hours were 3, 6, and 11% at temperatures of 30, 40, and 50 °C, respectively(4).

GROUND WATER: Benfluralin was detected at a concn of 0.03 ug/L in a groundwater sample collected from a domestic well in the Ozark mountains water basin(1). Benfluralin was detected in 1 out of 94 wells sampled across the Mid Western United States above the reporting limit of 0.004 ug/L(2). Benfluralin was detected in 1 out of 1,012 wells and 22 springs sampled across the United States United States at a concn of 0.004 ug/L(3).

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: Inhalation of material may be harmful. Contact may cause burns to skin and eyes. Inhalation of Asbestos dust may have a damaging effect on the lungs. Fire may produce irritating, corrosive and/or toxic gases. Some liquids produce vapors that may cause dizziness or suffocation. Runoff from fire control may cause pollution. (ERG, 2016)

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. (ERG, 2016)

Skin decontamination. Skin contamination should be treated promptly by washing with soap and water. Contamination of the eyes should be treated immediately by prolonged flushing of the eyes with large amounts of clean water. If dermal or ocular irritation persists, medical attention should be obtained without delay. /Other herbicides/|Gastrointestinal decontamination. Ingestions of these herbicides are likely to be followed by vomiting and diarrhea due to their irritant properties. Management depends on: (1) the best estimate of the quantity ingested, (2) time elapsed since ingestion, and (3) the clinical status of the subject. Activated charcoal is probably effective in limiting irritant effects and reducing absorption of most or all of these herbicides. Aluminum hydroxide antacids may be useful in neutralizing the irritant actions of more acidic agents. Sorbitol should be given to induce catharsis if bowel sounds are present and if spontaneous diarrhea has not already commenced. Dehydration and electrolyte disturbances may be severe enough to require oral or intravenous fluids. ... If large amounts of herbicide have been ingested and the patient is seen within an hour of the ingestion, gastrointestinal decontamination should be considered ... If the amount of ingested herbicides was small, if effective emesis has already occurred, or if treatment is delayed, administer activated charcoal and sorbitol by mouth. /Other herbicides/|Intravenous fluids. If serious dehydration and electrolyte depletion have occurred as a result of vomiting and diarrhea, monitor blood electrolytes and fluid balance and administer intravenous infusions of glucose, normal saline, Ringer's solution, or Ringer's lactate to restore extracellular fluid volume and electrolytes. Follow this with oral nutrients as soon as fluids can be retained. /Other herbicides/|Supportive measures are ordinarily sufficient for successful management of excessive exposures to these herbicides ...
