PHYSIOLOGICAL GROWTH PROCESSES ASSOCIATED WITH SEED GERMINATION.
BALAN WAS ONE OF A
GROUP OF HERBICIDES TESTED IN ONE OR MORE OF 4 DIFFERENT MICROBIAL SYSTEMS.
APPARENTLY NO POINT MUTATIONS WERE INDUCED.
DATA OBTAINED WITH TECHNICAL BENEFIN
IN RAT, DOG, RABBIT, CHICKEN & FISH INDICATE NO HAZARD TO ANY SPECIES EXCEPT
FISH. PHYSICAL PROPERTIES, NAMELY BINDING TO SOIL, & NON-LEACHING, ELIMINATE
THIS PROBLEM.
Skin application of 200 mg/kg and eye
application to rabbits produced no irritation. In 2 yr feeding trials the
no-effect level for rats was 1000 mg/kg diet.
Results of a chronic oral bioassay in dogs
(four animals/sex/dose) established a no observed effect level of 25 mg/kg/day
that was associated with a slight depression of erythrocyte counts with no
reduction in blood hemoglobin concentrations or hematocrit, and a lowest
observed effect level of 125 mg/kg/day that was associated with increased
relative liver weights and depressed blood hemoglobin concentrations and
hematocrit.
Emulsifiable concentrate formulations
containing benfin have caused severe eye irritation in laboratory animals. Benefin
may cause skin sensitization reactions in certain individuals.

Mechanism of Action:

Environmental Fate & Exposure:
Environmental Fate/Exposure Summary:
Benefin will be
released in the environment during its manufacture and use as a herbicide. If
released to soil, the loss of benefin should occur due
to biodegradation, photolysis and volatilization. Half-lives of benefin
in soil range from 0.7-4 months. Benefin is expected to
have low mobility in soils. The major pathways for the loss of benefin
from water may be biodegradation, photolysis and volatilization.
Bioconcentration of benefin in aquatic organisms should
be important. Reaction with photochemically produced hydroxyl radicals may be
important for the loss of vapor phase benefin in the
atmosphere. The half-life of benefin due to this
reaction has been estimated to be 3.1 hrs. Partial removal of benefin
will also occur as a result of dry and wet deposition. Applicators of benefin
and farm workers are the most likely people for exposure to benefin
by inhalation and dermal routes. (SRC)
Probable Routes of Human Exposure:
Applicators and field workers are the most
likely group for exposure to benefin(SRC). Judging from
the formulations used for field application, the most probable routes of
exposure to benefin among this group would be
inhalation and dermal contact(1,SRC).
PERSONNEL WHO FORMULATE OR APPLY BENEFIN
HAVE NOT EXPERIENCED DISCOMFORT OR UNTOWARD EFFECTS.
Natural Pollution Sources:
Benefin is not known
to occur naturally. (SRC)
Artificial Pollution Sources:
Since benefin is
commercially produced and used as a herbicide(1), it will be released to the
environment during use and may be released during production(SRC).
Environmental Fate:
WHEN SOIL TREATED WITH BENEFIN
WAS FLOODED WITH WATER, BENEFIN DECOMP RAPIDLY. ONLY
4.6% WAS DETECTABLE AFTER 16 DAYS. THE MAJOR DEGRADATION PRODUCTS WERE BENEFIN
WITH ONE NITRO GROUP REDUCED; WITH BOTH NITRO GROUPS REDUCED; & WITH BOTH
NITRO GROUPS REDUCED PLUS REMOVAL OF BOTH ALKYL GROUPS. FIVE OTHER METABOLITES
WERE DETECTED. THESE CMPD ... CONSTITUTED LESS THAN 5% OF THE TOTAL
RADIOACTIVITY. EXTRACTABLE POLAR PRODUCTS WERE OBSERVED & BELIEVED TO BE
AROMATIC AMINE CONDENSATION PRODUCTS. UNDER AEROBIC CONDITIONS, BENEFIN
DEGRADATION IN SOIL WAS SLOWER. /STRUCTURAL FORMULAS OF DEGRADATION PRODUCTS
GIVEN IN SOURCE/
BENEFIN DECOMP
RAPIDLY IN SOIL UNDER DEFINED ANEROBIC CONDITIONS, WITH APPROX 5% DETECTABLE
AFTER 16 DAYS. UNDER DEFINED AEROBIC CONDITIONS, 50% OF THE ORIGINALLY
INCORPORATED BENEFIN WAS DETECTABLE AFTER 120 DAYS
& ONLY 12.1% AFTER 352 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.
TERRESTRIAL FATE: Biodegradation,
volatilization and photolysis may all play significant roles for the loss of benefin
from soils(1). A Koc value of 9000(2) indicates that benefin
should remain strongly adsorbed in most soils and leaching of benefin
from most soils should not be important(3,SRC). The persistence of benefin
in soil will depend on the soil type, moisture content and the temperature of
soil(4). The persistence of benefin under field use
conditions may be close to a year(5).
AQUATIC FATE: Based on studies in soil,
photolysis by sunlight and biodegradation may be important for the degradation
of benefin in water(1,SRC). Based on an estimation
method(2) and a Henry's Law constant value of 2.91X10-4 atm cu m/mole estimated
from the ratio of vapor pressure(3) and water solubility(3), the volatilization
half-life of benefin from a model river of depth 1 m
flowing at a current speed of 1 m/sec and a wind speed of 3 m/sec would be 10.8
hrs(SRC). A Koc value of 9000(3) indicates that benefin
may be strongly adsorbed to suspended solids and sediment in water(SRC). The BCF
values of 2160 and about 2000 estimated from regression equations(2) and a log
Kow value of 4.69(4) and a water solubility of 0.1 mg/l(3) indicates that
bioconcentration of benefin in aquatic organisms will
be an important environmental process(SRC).
ATMOSPHERIC FATE: Based on a measured vapor
pressure of 6.6X10-5 mm Hg at 25 deg C(1), benefin
should exist both in the particulate and in the vapor phase in air(2,SRC). Based
on an estimation method(3-4), vapor phase benefin may
be removed from the atmosphere with an estimated half-life of 3.1 hrs due to
reaction with photochemically produced hydroxyl radicals(SRC). Partial removal
of particulate benefin from the air may occur by dry
deposition(SRC). Both vapor and particle phase benefin
may be partly removed from the atmosphere by wet deposition(SRC).
Environmental Biodegradation:
/IT IS SUGGESTED/ THAT MICROORGANISMS DO PLAY
A ROLE IN THE DISAPPEARANCE OF BENEFIN FROM SOIL.
Biodegradation of benefin
in soil occurs via oxidative and reductive pathways(1). Oxidation classically
occurs in aerobic soils and reduction in anaerobic soils. However, in flooded
field soils, both oxidation and reduction products have been observed(1). In
field soil, oxidative biodegradation of benefin leads
to dealkylation products followed by reduction of nitro group to amino
products(1,4). Rates of biodegradation of benefin is
dependent on soil temperature and moisture content and the rate is faster at 30
deg C compared to 4 deg C, and in dry soil compared to water-saturated field
soils(2-3). The biodegradation is faster in soils containing higher organic
carbon contents(3,5). The biodegradation half-lives of benefin
in a loam and a sandy loam soil were 0.7 month and 1.5 months, respectively, at
30 deg C(3).
Environmental Abiotic Degradation:
MATERIAL REMAINING ON THE SOIL SURFACE CAN BE
SUBJECT TO PHOTODECOMPOSITION.
Degradation of benefin
was observed when glass plates coated with soils containing benefin
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% benefin
photodegraded from glass plates coated with soil containing benefin(3-4).
Therefore, photodecomposition of benefin from water and
soil surfaces should occur(SRC).
Based on an estimation method(1-2), the rate
constant for the reaction of vapor phase benefin with
hydroxyl radicals in air is 8.20X10-11 cu cm/molecule-sec(SRC). This corresponds
to a half-life of 3.1 hrs, based on a 12 hr average OH concentration of 1.5X10+6
radicals/cu cm in th atmosphere.
Environmental Bioconcentration:
Based on regression equations(3),
bioconcentration factors (BCFs) of about 2000 and 2160 can be estimated from a
water solubility of 0.1 mg/l(1) and a log Kow of 4.69(2), respectively(SRC).
These BCF values indicate that bioconcentration of benefin
in aquatic organisms may be an important environmental pathway(4,SRC).
Soil Adsorption/Mobility:
The mean measured Koc value of benefin
in 10 Wisconsin soil was 609(2). Other investigators have suggested Koc values
of 10,700(1), 10,715(4), and 9,000(3). Benefin 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 benefin(6). Therefore, it was concluded that
benefin was immobile in soil(6).
Volatilization from Water/Soil:
Based on a Henry's Law constant of 2.91X10-4
atm-cu m/mole(1) estimated from the ratio of vapor pressure of 6.6X10-5 mm Hg(1)
and a water solubility of 0.1 mg/l(1), the volatilization half-life of benefin
from a model river of depth 1 m flowing at a current speed of 1 m/sec and a wind
speed of 3 m/sec would be 10.8 hrs(2,SRC). However, when the effect of
adsorption on volatility is considered, the estimated volatilization half-life
of benefin from a model pond is 160 days(3,SRC). The
volatilization loss of benefin from soil was found to
one of the highest among 11 dinitroanilines tested and the volatilization loss
increased with increase of soil temperature and decrease of soil moisture
content(4). The volatilization loss was 2.4% from a soil in 3 hrs at 30 deg C,
but increased to 23% at 50 deg C(4). The volatilization loss of benefin
from soil increases significantly with moisture content of soil from air dryness
to field capacity but did not significantly increase from field capacity to
saturation(4-6).

Preventive Measures:
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.
