**Emergency Overview**
**Physical Description & Colour:** Light milky white suspension concentrate.
**Odour:** No data re odour.
**Major Health Hazards:** Amitrole has a very low acute toxicity to humans and animals. Associated symptoms in humans include skin rash, vomiting, diarrhoea, and nose bleeds. Poisoning by Amitrole is characterized by increased intestinal peristalsis (this may lead to diarrhoea), fluid in the lungs, and haemorrhages of various organs. This product is harmful if swallowed, may cause sensitisation by skin contact, possible risk of harm to the unborn child. Amitrole is classified by NTP as reasonably anticipated to be carcinogenic to humans. Glyphosate is classified as IARC as probably carcinogenic to humans.

# Section 3 - Composition/Information on Ingredients

| Ingredients | CAS No | Conc,% | TWA (mg/m³) | STEL (mg/m³) |
| :--- | :--- | :--- | :--- | :--- |
| Amitrole | 61-82-5 | 60g/L | 0.2 | not set |
| Glyphosate (as the isopropylamine salt) | 1071-83-6 | 100g/L | not set | not set |
| Oxyfluorfen | 42874-03-3 | 15g/L | not set | not set |
| Terbuthylazine | 5915-41-3 | 350g/L | not set | not set |
| Other non hazardous ingredients | secret | to 100 | 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 SWA 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 may be equalled (but should not be exceeded) for no longer than 15 minutes and should not be repeated 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:** An information profile for Amitrole is available at
**Acute toxicity:** Amitrole has a very low acute toxicity to humans and animals. Associated symptoms in humans include skin rash, vomiting, diarrhoea, and nose bleeds. Poisoning by Amitrole is characterized by increased intestinal peristalsis (this may lead to diarrhoea), fluid in the lungs, and haemorrhages of various organs. No toxic effects were observed in a woman who ingested 20 mg/kg, but a single dose of 1200 mg/kg reduced iodine uptake by the thyroid in healthy persons. Amitrole is a mild skin and eye irritant. The oral and dermal LD50 values for Amitrole in rats are greater than 5000 mg/kg. Studies have reported oral LD50 values as high as 15,000 mg/kg in mice and 24,600 mg/kg in rats. In one study, the largest doses tested, 4080 mg/kg orally and 2500 mg/kg dermally, produced no toxic effects on rats. The dermal LD50 in rabbits is greater than 200 mg/kg.
**Chronic toxicity:** Feeding of Amitrole to rats at dietary doses of 3 or 6 kg/mg/day for 2 weeks caused enlargement of the thyroid and reduced uptake of iodine. A dietary dose of 50 mg/kg/day produced significant enlargement of the thyroid after 3 days of feeding. Several studies have shown that Amitrole inhibits the activity of various liver enzymes. Long-term exposure to Amitrole can cause reversible goitres.
**Reproductive effects:** It is unlikely that reproductive effects will occur in humans in normal circumstances.

**Teratogenic effects:** Birth defects have occurred in the pups of pregnant rabbits, rats, and mice exposed to Amitrole, but only at doses high enough to also produce signs of toxicity in the mothers. Teratogenic effects in humans are unlikely in normal circumstances.
**Mutagenic effects:** One laboratory assay has shown Amitrole to be weak mutagen. All other assays have shown no mutagenic effects. These data suggest that Amitrole is weakly or nonmutagenic.
**Carcinogenic effects:** Amitrole has induced thyroid and liver tumours in rats and mice after lifetime high dose exposures.
**Organ toxicity:** Animal studies have shown that Amitrole's main effects are on the thyroid and liver.
**Fate in humans and animals:** Amitrole is rapidly and completely absorbed into the body through the gastrointestinal tract when eaten. It is excreted through the urine. The highest concentrations in all tissues generally occur within 1 hour after exposure.
There is no data to hand indicating any particular target organs.
Amitrole is a SWA Class 3 Reproductive risk, possible risk of harm to the unborn child.
**For this product:** LD50 (Oral), Rat >5100mg/kg (Calculated)

**Effects on other organisms:** Amitrole inhibits the growth of bacteria. It is nontoxic to bees.
**Environmental Fate:**
**Breakdown in soil and groundwater:** Amitrole has low soil persistence. Its half-life is 14 days. Microbial breakdown of Amitrole takes 2 to 3 weeks in warm, moist soil. Some chemical degradation may also occur in soils. Loss of Amitrole from soils by volatilization or photodegradation is minor.
**Breakdown in water:** In aquatic environments, Amitrole does not break down by hydrolysis or photolysis, volatilize, nor bioaccumulate in aquatic organisms. The biodegradation half-life for Amitrole in water is about 40 days. Degradation of Amitrole in open waters may occur through oxidation by other chemicals.
**Breakdown in vegetation:** Amitrole is readily absorbed and rapidly translocated in the roots and leaves of higher plants. But, plants are able to metabolize Amitrole in 1 to 4 weeks. Amitrole residues were not detected in crops planted into soil 1 to 50 days after treatment with Amitrole.
