Summary:

Poison Schedule 5.

Will irritate eyes and skin. Avoid inhaling dust. Harmful if swallowed. May cause harm to the unborn child.

Details:

Mammalian toxicity -

Acute oral LD50 - 3476 mg/kg (male rats), 1635 mg/kg (female rat) [For comparison table salt is 3000 mg/kg]

Acute dermal LD50 - >2000 mg/kg (rabbit).

Skin - moderate irritant

Eye - May be an irritant

Vapour inhalation - may result in respiratory irritation. LC50 - >2.99 mg/L/4hr air (rat).

Chronic oral toxicity NOEL - ppm for two years.

Teratogenic with repeated doses in rats NOEL 45 mg/kg/day rat.

Foetotoxic effects in rats and rabbits. NOEL 15 mg/kg/day in rabbits and 5 mg/kg/day in rats.

High doses produce adverse effects in testes of rats (NOEL 1 mg/kg/day) and dogs (NOEL 5 mg/kg/day).

Not carcinogenic (i.e. does not cause cancer).

Acceptable daily intake for humans is 0.005 mg/kg/day.

Other Species -

Birds - low toxicity. LD50 1221 to >2000 mg/kg.

Fish - toxicity LC50 >6.9 ppm.

Invertebrates - toxicity.

Bees - Low toxicity. LD50 >200ug/bee

Algae and aquatic plants - high toxicity.

25 TOXICITY SYMPTOMS:

Swallowing can result in nausea, vomiting and abdominal pain.

26 FIRST AID:

Contact a doctor or Poisons Information Centre on 13 11 26.

If Swallowed - Rinse mouth with water. Give plenty of water to drink. If vomiting occurs give further water. Contact a doctor.

If on Skin - Wash skin thoroughly with soap and water. If swelling, reddening, blistering or other irritation occurs then seek medical advice.

If in Eyes - Flush with water for 15 minutes. Contact a doctor.

If Inhaled - Remove patient from contaminated area to fresh air. Seek medical advice if effects persist.

Advice to Doctor - Treat symptomatically.

27 ENVIRONMENTAL FATE:

It has a half life in soil of days. Rapidly degrades at pH5

Moderate mobility in soil at low pH and high mobility at high pH

It has an EPA classification for soil mobility that ranges from

Ground water contamination. Rapid degradation at pH5. No hydrolysis at pH9 but there is evidence for photo degradation.

Replanting intervals

Accumulation in milk and tissues. Rapidly metabolised in rats with 90% of the dose excreted in 7 days. It is not expected to bio accumulate in animal tissues.

31 PROPERTIES:

Water solubility at 25 C. - Dispersible in water;

Oil solubility -

Octanol:Water ratio at 25 C. - at pH 5;

Vapour Pressure at 25 C. -

Dissociation constant - pKa

Melting point - C.

Molecular weight -

Half life in water - days at pH5 and 35 C.
