Emergency Overview
Physical Description & colour: Brown-orange coloured liquid.
Odour: Aromatic hydrocarbon odour.
Major Health Hazards: Pendimethalin is slightly to practically nontoxic by ingestion, with reported oral LD50 values
of 1050 mg/kg to greater than 5000 mg/kg in rats. It is slightly to practically nontoxic by skin exposure, with reported
dermal LD50 values of greater than 2000 mg/kg. It is not a skin irritant or sensitizer in rabbits or guinea pigs, but it
causes mild eye irritation in rabbits. The inhalation 4-hour LC50 for technical Pendimethalin in rats is 320 mg/L,
indicating practically no toxicity via this route. Some formulated products may show slight toxicity by inhalation, and
may have a greater capacity to cause skin irritation. Inhalation of dusts or fumes may be mildly to moderately irritating
to the linings of the mouth, nose, throat, and lungs. harmful if swallowed, possible skin sensitiser, if aspirated, may
cause lung damage.
Potential Health Effects
See section 11 for Chronic exposure studies.
Inhalation
Short term exposure: Available data indicates that this product is not harmful. However product may be mildly
irritating, although unlikely to cause anything more than mild transient discomfort.
Skin Contact:

Pendimethalin 40487-42-1 33 w/v not set not set
Solvent naphtha (petroleum), light arom. 64742-95-6 54 w/v not set not set
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 4 - First Aid Measures
General Information:
You should call The Poisons Information Centre if you feel that you may have been poisoned, burned or irritated by
this product. The number is 13 1126 from anywhere in Australia (0800 764 766 in New Zealand) and is available at all
times. Have this MSDS with you when you call.
Inhalation: No first aid measures normally required. However, if inhalation has occurred, and irritation has
developed, remove to fresh air and observe until recovered. If irritation becomes painful or persists more than about
30 minutes, seek medical advice.
Skin Contact: Gently blot away excess liquid. Wash gently and thoroughly with water (use non-abrasive soap if
necessary) for 5 minutes or until chemical is removed.
Eye Contact: Flush the contaminated eye(s) with lukewarm, gently flowing water for 10 minutes while holding the
eyelid(s) open. Obtain medical advice if irritation becomes painful or lasts more than a few minutes. Take special care
if exposed person is wearing contact lenses.
Ingestion: If swallowed, do NOT induce vomiting. Wash mouth with water and contact a Poisons Information
Centre, or call a doctor.
Section 5 - Fire Fighting Measures
Fire and Explosion Hazards: This product is classified as flammable. There is a moderate risk of an explosion
from this product if commercial quantities are involved in a fire. Firefighters should take care and appropriate

Section 6 - Accidental Release Measures
Accidental release: In the event of a major spill, prevent spillage from entering drains or water courses. Evacuate
the spill area and deny entry to unnecessary and unprotected personnel. Immediately call the Fire Brigade. Wear full
protective clothing including eye/face protection. All skin areas should be covered. See below under Personal
Protection regarding Australian Standards relating to personal protective equipment. Suitable materials for protective
clothing include Nitrile. Eye/face protective equipment should comprise as a minimum, protective goggles. If there is a
significant chance that vapours or mists are likely to build up in the cleanup area, we recommend that you use a
respirator. It should be fitted with a type A cartridge, suitable for organic vapours. Otherwise, not normally necessary.
Stop leak if safe to do so, and contain spill. Absorb onto sand, vermiculite or other suitable absorbent material. If spill
is too large or if absorbent material is not available, try to create a dike to stop material spreading or going into drains
or waterways. Avoid using sawdust or other combustible material. Any electrical equipment should be non-sparking.
Any equipment capable of building an electrostatic charge should be electrically grounded. Sweep up and shovel or
collect recoverable product into labelled containers for recycling or salvage, and dispose of promptly. Recycle
containers wherever possible after careful cleaning. Refer to product label for specific instructions. After spills, wash

its compounds, and under some circumstances, oxides of nitrogen. Occasionally hydrogen cyanide gas. Water.
Carbon monoxide poisoning produces headache, weakness, nausea, dizziness, confusion, dimness of vision,
disturbance of judgment, and unconsciousness followed by coma and death.
Polymerisation: This product will not undergo polymerisation reactions.
Section 11 - Toxicological Information
Toxicity: Chronic toxicity: Increases in alkaline phosphatase level and liver weight were produced in dogs fed 50
mg/kg/day for 2 years, but not at a dose of 12.5 mg/kg/day. In a 90-day feeding study of rats, no effects were
observed at doses of 40 mg/kg/day.
Reproductive effects: In a three-generation reproductive study of rats tested at levels up to 250 mg/kg/day, there
were slightly fewer offspring and they showed decreased weight gain from weaning to maturity. No effects were
observed at 30 mg/kg/day. This evidence suggests that Pendimethalin is unlikely to cause reproductive effects in
humans under normal circumstances.
Teratogenic effects: No birth defects and no toxic effects on foetuses occurred when pregnant rats were given 500
mg/kg/day, the highest dose tested. No foetotoxic or teratogenic effects were seen at the highest dose tested (60
mg/kg/day) in a teratology study with rabbits, although maternal toxicity was seen at 30 mg/kg/day. It does not appear
that Pendimethalin is teratogenic.
Mutagenic effects: Several mutagenicity studies, including tests on live animals and mammalian and bacterial cell
cultures, have all indicated that Pendimethalin has no mutagenic activity.
Carcinogenic effects: Pendimethalin did not increase tumour formation in mice given dietary doses of 75 mg/kg/day
over an 18-month period. This evidence suggests that Pendimethalin is not carcinogenic.
Organ toxicity: Chronic exposure to Pendimethalin has resulted in increased liver weights in test animals.
Fate in humans and animals: Pendimethalin is largely unabsorbed from the gastrointestinal tract, and excreted
unchanged in the faeces. Pendimethalin, which does become absorbed into the bloodstream from the gastrointestinal
tract, is rapidly metabolized in the kidneys and liver and is then excreted as metabolites via urine. One day after
administration to rats, 90% of a 37 mg/kg dose was recovered in faeces and urine. After 4 days this figure was 96%.
Lower doses resulted in almost 100% excretion within 4 days. Tissue burdens of the compound were on the order of
0.3 mg/kg, with slightly higher concentrations in the body fat.
Section 12 - Ecological Information
Toxic to aquatic organisms, may cause long-term adverse effects to the aquatic environment. Insufficient data to be
sure of status.
Effects on birds: Pendimethalin is slightly toxic to birds, with an acute oral LD50 of 1421 mg/kg in mallard duck and 8-
day dietary LC50 values of greater than 3149 mg/kg in bobwhite quail, and greater than 10,900 mg/kg in mallard duck.

This revision issued: September, 2005
Effects on aquatic organisms: Pendimethalin is highly toxic to fish and aquatic invertebrates. The reported 96-hour
LC50 for Pendimethalin in bluegill sunfish is 199 碌g/L, in rainbow trout is 138 碌g/L, and in channel catfish is 420 碌g/L.
The 48-hour LC50 in Daphnia magna, a small freshwater crustacean, is 280 碌g/L. The bioconcentration factor for this
compound in whole fish is 5100, indicating a moderate potential to accumulate in aquatic organisms.
Effects on other organisms: Pendimethalin is nontoxic to bees.
Environmental Fate:
Breakdown in soil and groundwater: Pendimethalin is moderately persistent, with a field half-life of approximately
40 days. It does not undergo rapid microbial degradation except under anaerobic conditions. Slight losses of
Pendimethalin can result from photodecomposition and volatilization. Pendimethalin is strongly adsorbed by most
soils. Increasing soil organic matter and clay is associated with increased soil binding capacity. It is practically
insoluble in water, and thus will not leach appreciably in most soils, and should present a minimal risk of groundwater
contamination.
Breakdown in water: Pendimethalin is stable to hydrolysis, but may be degraded by sunlight in aquatic systems.
Pendimethalin may also be removed from the water column by binding to suspended sediment and organic matter. It
is rapidly degraded under anaerobic conditions once precipitated to sediment.
Breakdown in vegetation: Pendimethalin is absorbed by plant roots and shoots, and inhibits cell division and cell
elongation. Once absorbed into plant tissues, translocation is limited and Pendimethalin breaks down via oxidation.
Pendimethalin is not absorbed by the leaves of grasses, and only very small amounts are taken up by plants from the
soil. Residues on crops at harvest are usually below detectable levels (0.05 ppm).
Section 13 - Disposal Considerations
Disposal: There are many pieces of legislation covering waste disposal and they differ in each state and territory, so
each user must refer to laws operating in their area. In some areas, certain wastes must be tracked. The Hierarchy of
Controls seems to be common - the user should investigate: Reduce, Reuse, and Recycle and only if all else fails
should disposal be considered. Note that properties of a product may change in use, so that the following suggestions
may not always be appropriate. The following may help you in properly addressing this matter for this product. Special
help is available for the disposal of Agricultural Chemicals. The product label will give general advice regarding
disposal of small quantities, and how to cleanse containers. However, for help with the collection of unwanted rural
chemicals, contact ChemClear (02) 6230 4799 http://www.chemclear.com.au/ and for help with the disposal of empty
drums, contact DrumMuster http://www.drummuster.com.au/ where you will find contact details for your area.
