Section 11 - Toxicological Information
Toxicity: Acute toxicity: Metribuzin is harmful orally, with reported oral LD50 values of 1090 to 2300 mg/kg in rats,
700 mg/kg in mice and 245 to 274 mg/kg in guinea pigs. It is practically nontoxic dermally, with a dermal LD50 of
20,000 mg/kg in rabbits. The 4-hour inhalation LC50 for Metribuzin in rats is greater than 0.65 mg/L, indicating
moderate toxicity via the inhalation route. Metribuzin has been shown not to irritate the skin or eyes of rats, rabbits,
guinea pigs, or human volunteers. Effects of high acute exposure in Metribuzin poisoned rats included narcosis
(stupor) and laboured breathing. Deaths occurred within 24 hours, and survivors recovered slowly without permanent
effects.
Chronic toxicity: No ill effects were observed in dogs fed dietary doses of 12.5 mg/kg/day for 3 months. No effects
were apparent in rats receiving 2.5 mg/kg/day over 3 months, but doses of 25 and 75 mg/kg/day caused enlarged
livers and thyroid glands. In 2-year feeding studies with rats and dogs, results showed no observable effects at doses
of 5 mg/kg/day in rats and 2.5 mg/kg/day in dogs. Reduced weight gain, an increase in the number of deaths, blood
chemistry changes, and liver and kidney damage were observed in a 2-year study in which dogs were given 1500
ppm or 37.5 mg/kg/day of Metribuzin.
Reproductive effects: Doses of 15, 45, or 135 mg/kg/day of technical Metribuzin were administered by gavage to
rabbits on days 6 through 18 of pregnancy. No effects on the mothers were observed at a dose of 45 mg/kg, but 135
mg/kg lowered maternal weight gain. No effects on the foetuses were observed at any of the doses tested. A three-
generation study in rats at doses of up to 15 mg/kg/day (the highest dose tested), showed no influence on
reproduction. Metribuzin does not cause reproductive effects.
Teratogenic effects: In rats, reduced foetal body weights were seen at doses of 70 mg/kg/day, and developmental
delays were observed at doses of 200 mg/kg/day. Metribuzin did not show teratogenic activity in rabbits at doses of
up to 85 mg/kg/day, but did decrease weight gain in offspring. These data suggest that Metribuzin is unlikely to cause
teratogenic effects in humans under normal circumstances.
Mutagenic effects: Tests on live animals and on tissue cultures show that Metribuzin has no mutagenic activity.
Carcinogenic effects: There were no indications of carcinogenic effects in rats receiving dietary doses of up to 15
mg/kg/day for 2 years, nor in mice fed up to about 380 mg/kg/day for 2 years. These data suggest that Metribuzin is
not carcinogenic.
Organ toxicity: In single high dose studies, Metribuzin appears to depress the central nervous system. Other studies
indicate that the target organs of Metribuzin are the thyroid gland and the liver.
Fate in humans and animals: After Metribuzin is absorbed, it is rapidly distributed in the body and excreted
unchanged in the urine. In mammals, 90% elimination occurs within 96 hours, about equally distributed between the
urine and faeces.
Section 12 - Ecological Information
Very toxic to aquatic organisms, may cause long-term adverse effects to the aquatic environment.
Breakdown in soil and groundwater: Metribuzin is of moderate persistence in the soil environment. The half-life of
Metribuzin varies according to soil type and climatic conditions. Soil half-lives of 30 to 120 days have been reported; a
representative value may be approximately 60 days. Metribuzin is poorly bound to most soils and soluble in water,
giving it a potential for leaching in many soil types. Soil mobility is affected by many site-specific variables, including
the amount of soil organic matter, particle size distribution, porosity, rainfall, and application rates. Metribuzin has
been detected in Ohio rivers and Iowa wells and groundwater. The major mechanism by which Metribuzin is lost from
soil is microbial degradation. Losses due to volatilization or photodegradation are not significant under field
conditions.
Breakdown in water: The half-life of Metribuzin in pond water is approximately 7 days. If present, Metribuzin would
most likely be found in the water column rather than the sediment, due to its low binding affinity and high water
solubility.

Breakdown in vegetation: Metribuzin is absorbed through the leaves when plants are given surface treatment, but
the primary route for uptake is through the root system. From the roots, it is translocated upward, becoming
concentrated in the roots, stems, and leaves of treated plants. In non-susceptible plants it is deaminized to more
water-soluble conjugates; in susceptible plants it is not metabolized and disrupts photosynthesis in the chloroplast.
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 1800 008 182 http://www.chemclear.com.au/ and for help with the disposal of empty
