This is a commercial product whose exact ratio of components may vary slightly. Minor quantities of other non
hazardous ingredients are also possible.
The TWA exposure value is the average airborne concentration of a particular substance when calculated over a normal 8 hour working day for a 5
day working week. The STEL (Short Term Exposure Limit) is an exposure value that should not be exceeded for more than 15 minutes and should
not be repeated for more than 4 times per day. There should be at least 60 minutes between successive exposures at the STEL. The term "peak "is
used when the TWA limit, because of the rapid action of the substance, should never be exceeded, even briefly.

Section 11 ?? Toxicological Information
Toxicity: Acute toxicity: MCPA acid is harmful via ingestion, with reported oral LD50 values for the technical
product in rats ranging from 700 mg/kg to 1160 mg/kg and ranging in mice from 550 to 800 mg/kg. It is harmful via the
dermal route as well, with reported dermal LD50 values ranging from greater than 1000 mg/kg in rats to greater than
4000 mg/kg in rabbits. Symptoms in humans from very high acute exposure could include slurred speech, twitching,
jerking and spasms, drooling, low blood pressure, and unconsciousness.
Chronic toxicity: Dietary levels of approximately 50 mg/kg/day and 125 mg/kg/day over 7 months caused reduced
feeding rates and retarded growth rates in rats. White blood cell counts and ratios were not affected, but some
reductions in red blood cell counts and hemoglobin did appear to be associated with exposure to MCPA at oral dose
levels of approximately 20 mg/kg/day. In the same study, oral doses of approximately 5 mg/kg/day caused increased
relative kidney weights, and oral doses of approximately 20 mg/kg/day caused increased relative liver weights.
Another study in rats showed no effects on kidney or liver weights over an unspecified period at oral doses of 60
mg/kg/day, but oral doses of 150 mg/kg/day did cause reversible increases in these weights over a course of 3
months. Very high dermal doses of 500 mg/kg/day caused reduced body weight, and even higher dermal doses of
1000 and 2000 mg/kg/day resulted in increased mortality and observable changes in liver, kidney, spleen, and thymus
tissue.
Reproductive effects: A two-generation rat study at doses of up to 15 mg/kg/day affected reproductive function.
Even smaller amounts of the compound were toxic to the fetuses. Dogs receiving relatively small amounts of MCPA
(8 and 16 mg/kg) for 13 weeks showed adverse sperm and testes changes. It is unlikely that humans will experience
these effects under normal exposure conditions.
Teratogenic effects: Offspring of pregnant rats fed low to moderate doses of MCPA (20 to 125 mg/kg) on days 6 to
15 of gestation, had no birth defects. However, when the ethyl ester form of MCPA was fed to pregnant rats (2 to 100
mg/kg/day on days 8 to 15 of gestation), cleft palate, heart defect, and kidney anomalies were observed in the
offspring. Mice fed 5 to 100 mg/kg/day of MCPA on days 6 to 15 showed significantly reduced fetal weight and
delayed bone development at the highest dose. Teratogenic effects in humans are unlikely at expected exposure
levels.
Mutagenic effects: MCPA is reportedly weakly mutagenic to bone marrow and ovarian cells of hamsters, but
negative results were reported for other mutagenic tests. It was negative in a bacterial test system (both with and
without metabolic activation), negative in spot tests, and negative in host-mediated tests. It produced no detectable
increase in chromosomal aberrations in house flies. Some irregularities occurred in gene transfer during cell division
in brewers yeast, although at levels which caused massive cell death. It appears that the compound poses little or no
mutagenic risk.
Carcinogenic effects: All of the available evidence on MCPA indicates that the compound does not cause cancer.
Forestry and agricultural workers occupationally exposed to MCPA in Sweden did not show increased cancer
incidence.
Organ toxicity: Target organs identified in animal studies include the liver, kidneys, spleen. and thymus. Farm worker
exposure has resulted in reversible anemia, muscular weakness, digestive problems, and slight liver damage.
Fate in humans and animals: MCPA is rapidly absorbed and eliminated from mammalian systems. Rats eliminated
nearly all of a single oral dose within 24 hours, mostly though urine with little or no metabolism. In another rat study,
three quarters of the dose was eliminated within 2 days. All was gone by the 8 days. Humans excreted about half of a
5 mg dose in the urine within a few days. No residues were found after day 5. Cattle and sheep fed low to moderate
doses of MCPA in the diet for 2 weeks showed no residues from levels less than about 18 mg/kg. The major
metabolite of MCPA is 2-methyl-4-chlorophenol in the free and conjugated form, which is formed in the liver.

Section 12 ?? Ecological Information
Effects on birds: MCPA is moderately toxic to wildfowl; the LD50 of MCPA in bobwhite quail is 377 mg/kg.
Effects on aquatic organisms: MCPA is only slightly toxic to freshwater fish, with reported LC50 values ranging from
117 to 232 mg/L in rainbow trout. MCPA is practically nontoxic to freshwater invertebrates, and estuarine and marine
organisms.
Effects on other organisms: It is nontoxic to bees, with a reported oral LD50 of 104??g/bee.
Environmental Fate:
Breakdown in soil and groundwater: MCPA and its formulations are rapidly degraded by soil microorganisms and it
has low persistence, with a reported field half-life of 14 days to 1 month, depending on soil moisture and soil organic
matter. Decreased soil moisture and microbial activity, as well as increased soil organic matter, will prolong the field
half-life for MCPA. With less than 10% organic matter in soil, the compound is degraded in 1 day and, with greater
than 10% levels in soil, it takes 3 to 9 days to degrade. The half-life is 5 to 6 days in slightly acidic to slightly alkaline
soils. MCPA readily leaches in most soils, but its mobility decreases with increasing organic matter. MCPA and its
formulations show little affinity for soil.
Breakdown in water: It is relatively stable to light breakdown , but can be rapidly broken down by microorganisms. In
sterilized water, it takes about 5 weeks for half of the compound to degrade due to the action of sunlight. In rice paddy
water, however, MCPA is almost totally degraded by aquatic microorganisms in under 2 weeks.
Breakdown in vegetation: MCPA is readily absorbed and translocated in most plants. It works by concentrating in
the actively growing regions of a plant (meristematic tissue), where it interferes with protein synthesis, cell division,
and ultimately the growth of non-resistant plants. It is actively broken down in plants, the major metabolite being 2-
methyl-4-chlorophenol.
