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 continued use. Under this pesticide reregistration program, EPA examines newer health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether the use of the pesticide does not pose unreasonable risk in accordance to newer safety standards, such as those described in the Food Quality Protection Act of 1996. Bendiocarb is found on List A, which contains most pesticides that are used on foods and, hence, have a high potential for human exposure. List A consists of the 194 chemical cases (or 350 individual active ingredients) for which EPA issued registration standards prior to FIFRA '88.

BENDIOCARB is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.

Estimated mean personal air concentrations of bendiocarb were determined for Jacksonville, Florida residents (estimated 290,000 people residing in 150,000 households) and Springfield/Chicopee, Massachusetts residents (estimated 135,000 people residing in 73,000 households) as determined by sampling over 24 hours and analysis by GCMS(1). Personal air collected from people living in Jacksonville contained bendiocarb in 14, 21, and 26% of the total samples from summer, spring, and winter sampling, respectively(2). Personal air concentrations of bendiocarb for Jacksonville residents were measured as 51.4 ng/cu m in the summer, 4.4 ng/cu m in the spring, and 3.5 ng/cu m in the winter(1). 2 and 1% of personal air samples obtained from people living in the Springfield/Chicopee, MA area in 1987 (spring sampling) and 1988 (winter sampling), respectively, contained detectable concentrations of bendiocarb (range of mean is 0.2 to 0.3 ng/cu m)(3). In a study of nine households in urban/suburban southeastern United States during August 1985, bendiocarb was detected in personal air in 3 households. The detection limit for the GC analysis was 10 ng/cu m(4).

A bendiocarb concentration of <0.2 ng/cu m was reported in personal air samples from mothers during the 32nd week of pregnancy among an inner-city cohort living in northern Manhattan or South Bronx, New York City, NY; sampling was conducted from 2001-2004(1).

If the compound has been ingested, rapid gastric lavage should be performed using 5% sodium bicarbonate. For skin contact, the skin should be washed with soap and water. If the compound has entered the eyes, they should be washed with large quantities of isotonic saline or water. In serious cases, atropine and/or pralidoxime should be administered. Anti-cholinergic drugs work to counteract the effects of excess acetylcholine and reactivate AChE. Atropine can be used as an antidote in conjunction with pralidoxime or other pyridinium oximes (such as trimedoxime or obidoxime), though the use of '-oximes' has been found to be of no benefit, or possibly harmful, in at least two meta-analyses. Atropine is a muscarinic antagonist, and thus blocks the action of acetylcholine peripherally.

Acute exposure to cholinesterase inhibitors can cause a cholinergic crisis characterized by severe nausea/vomiting, salivation, sweating, bradycardia, hypotension, collapse, and convulsions. Increasing muscle weakness is a possibility and may result in death if respiratory muscles are involved. Accumulation of ACh at motor nerves causes overstimulation of nicotinic expression at the neuromuscular junction. When this occurs symptoms such as muscle weakness, fatigue, muscle cramps, fasciculation, and paralysis can be seen. When there is an accumulation of ACh at autonomic ganglia this causes overstimulation of nicotinic expression in the sympathetic system. Symptoms associated with this are hypertension, and hypoglycemia. Overstimulation of nicotinic acetylcholine receptors in the central nervous system, due to accumulation of ACh, results in anxiety, headache, convulsions, ataxia, depression of respiration and circulation, tremor, general weakness, and potentially coma. When there is expression of muscarinic overstimulation due to excess acetylcholine at muscarinic acetylcholine receptors symptoms of visual disturbances, tightness in chest, wheezing due to bronchoconstriction, increased bronchial secretions, increased salivation, lacrimation, sweating, peristalsis, and urination can occur. Chronically high (>10 years) exposure leads to neuropsychological consequences including disturbances in perception and visuo-motor processing (A15321).

TERRESTRIAL FATE: Based on a classification scheme(1), a Koc range of 28(2) to 575(3) indicates that bendiocarb is expected to have very high to moderate mobility in soil(SRC). Volatilization of bendiocarb from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.9X10-8 atm-cu m/mole(SRC), based upon its vapor pressure, 3.45X10-5 mm Hg(4), and water solubility, 260 mg/L(4). Bendiocarb is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(4). Biodegradation carried out in soil showed a 48% loss within 42 days(5), suggesting that biodegradation is an important environmental fate process in soil(SRC).

TERRESTRIAL FATE: ... Bendiocarb is rapidly degraded in soil, via hydrolysis of the methyl carbamate and heterocyclic ring, followed by oxidation to polar and soil-bound residues, together with considerable mineralization of the phenyl ring to CO2. The rate of degradation of bendiocarb is pH-dependent, with slower breakdown under acidic conditions. DT50 values for the rate of decline of bendiocarb in agricultural soils and standard Speyer 2.2 range from 0.5 to 10 d, depending upon soil type, moisture and temperature. In adsorption/desorption studies, bendiocarb was hydrolyzed to 2,2-dimethyl-1,3-benzodioxol-4-ol (NC 7312). Bendiocarb and NC 7312 are weakly adsorbed (Koc 28-40); however, because it is rapidly degraded, bendiocarb should not leach. ...

AQUATIC FATE: Based on a classification scheme(1), Koc values ranging from 28(2) to 575(3) indicate that bendiocarb is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(4) based upon an estimated Henry's Law constant of 3.9X10-8 atm-cu m/mole(SRC), derived from its vapor pressure, 3.45X10-5 mm Hg(5), and water solubility, 260 mg/L(5). Hydrolysis, particularly under neutral or alkaline conditions, is expected to be a major fate process for this compound(SRC). Aqueous studies reported half-lives of 48 days, 4 days, and 45 minutes at pH values of 5, 7, and 9, respectively(6). According to a classification scheme(7), an estimated BCF of 6(SRC), from its log Kow of 1.70(8) and a regression-derived equation(9), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Photolysis half-life in water at 25 °C was 37 days(2). BOD values of 20-100% of the theoretical were reported in screening tests(10), suggesting that biodegradation may be an important environmental fate process in water(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), bendiocarb, which has a vapor pressure of 3.45X10-5 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase bendiocarb 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 16 hours(SRC), calculated from its rate constant of 2.4X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase bendiocarb may be removed from the air by wet or dry deposition(SRC). Bendiocarb is stable to light(4) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).

26% of sampled wheat grains, collected from 7 areas in Saudi Arabia, contained unreported concentrations of bendiocarb(1). Bendiocarb was not detected in a 1996 market basket survey that analyzed 1,579 samples from 8 markets in 6 Egyptian governates(2).

Bendiocarb is a cholinesterase or acetylcholinesterase (AChE) inhibitor. Carbamates form unstable complexes with chlolinesterases by carbamoylation of the active sites of the enzymes. This inhibition is reversible. A cholinesterase inhibitor suppresses the action of acetylcholine esterase. Because of its essential function, chemicals that interfere with the action of acetylcholine esterase are potent neurotoxins, causing excessive salivation and eye-watering in low doses. Headache, salivation, nausea, vomiting, abdominal pain and diarrhea are often prominent at higher levels of exposure. Acetylcholine esterase breaks down the neurotransmitter acetylcholine, which is released at nerve and muscle junctions, in order to allow the muscle or organ to relax. The result of acetylcholine esterase inhibition is that acetylcholine builds up and continues to act so that any nerve impulses are continually transmitted and muscle contractions do not stop.

/OTHER TERRESTRIAL SPECIES/ Other terrestrial species/ bendiocarb > chlorpyrifos > malathion > pyrethrins was the order of toxicity of nonthermal aerosol formulations of these insecticides to caged honeybees.

/OTHER TERRESTRIAL SPECIES/ Sexes and nymphal age classes of insecticide susceptible and resistant strains of the German cockroach, Blattella germanica, were evaluated for susceptibility to bendiocarb. Late stage nymphs had higher LC50s (ug/insect) and LD50s (ug/mg) than adult males. This reduced susceptibility to insecticides in late instar nymphs occurred irrespective of weight differences, type of insecticide, or strain of cockroach. Females had significantly higher LC50s (ug/insect) than males for bendiocarb (resistant strain). However, LD50s (ug/mg) for males and females were the same for bendiocarb (susceptible and resistant strains). Resistance ratios were 6-10 for bendiocarb in adult males and females, but ratios for 4 to 6 wk old nymphs were 53-100.

As with organophosphates, the signs and symptoms are based on excessive cholinergic stimulation. Unlike organophosphate poisoning, carbamate poisonings tend to be of shorter duration because the inhibition of nervous tissue acetylcholinesterase is reversible, and carbamates are more rapidly metabolized. Muscle weakness, dizziness, sweating and slight body discomfort are commonly reported early symptoms. Headache, salivation, nausea, vomiting, abdominal pain and diarrhea are often prominent at higher levels of exposure. Contraction of the pupils with blurred vision, incoordination, muscle twitching and slurred speech have been reported. (L795)

Bendiocarb acts through inhibition of cholinesterase activity which is rapidly reversible, the half-life of the inhibited enzyme is approximately 30 minutes.

Metabolism ... of an oral dose of (14)C bendiocarb by a human subject was similar to the pattern observed in animals; primarily as sulfate and glucuronide conjugates of the phenol, with minor amounts of conjugated bendiocarb and N-hydroxymethyl bendiocarb.

In all species examined, bendiocarb was metabolized via cleavage of the carbamate ester group to yield the phenol (2,2-dimethyl-1,3-benzoxodiol-4-ol), which was excreted as sulfate and glucuronide conjugates.

Spontaneous hydrolysis of the carbamate-cholinesterase complex occurs in vivo, leading to the disappearance of clinical effects within 24 hr. /Carbamate pesticides/

The carbamates are hydrolyzed enzymatically by the liver; degradation products are excreted by the kidneys and the liver. (L793)

In rats given a 1 mg/kg oral dose of (14)C bendiocarb, plasma levels of radioactivity peaked at 10 min after administration. Following a 2.5 mg/kg dose, radioactivity in the tissues 72 hr after administration ranged from 0.015 to 0.061 ppm (as bendiocarb). Six days after 10 day dietary administration of ring-labeled bendiocarb to rats ended, residues were detected in the fat, liver, kidneys, muscle, and brain, the levels being highest in the fat tissue. ... Within 2 days after oral administration of ring-labeled bendiocarb (at 0.125-10 mg/kg) to rats, 89-90% of the dose was eliminated in the urine, 2-6% in the expired air, and 2-6% in the feces. ...

In rats and a range of other mammals, rapidly absorbed following oral admin or inhalation, but not following skin contact. Rapidly detoxified and eliminated almost completely within 24 hr as the sulfate and glucuronide conjugate of the principal metabolite, 2,2-dimethyl-1,3-benzodioxol-4-ol.

Bendiocarb may be absorbed from the gastrointestinal tract or to a limited extent through the intact skin. Low vapor pressure makes inhalation unlikely except from airborne spray mist.

Male and female rats treated with a single oral dose of (14)C-bendiocarb at approximately 10 mg/kg body weight eliminated over 95% of the administered radioactivity in urine (89%), expired air (6%) and feces (2%) within 2 days of dosing. There was no significant sex different in rate and route of elimination.
