24 TOXICITY:

Summary:

Very dangerous. Poisonous if inhaled, swallowed or absorbed through eyes. Irritates the eyes and skin. Repeated exposure may cause allergic disorders. Avoid contact with eyes and skin. DO NOT inhale spray mist. May cause nose bleeds.

Details:

SUSMP classification (Poison schedule): S7.

Mammalian toxicity:

Acute oral LD50: LD50 (rat) 129 - 157 mg/kg for paraquat dichloride

LD50 (guinea pig) 30 - 58 mg/kg

LD50 (rat) 1100 - 24600 mg/kg for amitrole

[For comparison table salt is 3000 mg/kg]

TREATMENT OF PARAQUAT POISONING MUST COMMENCE AS RAPIDLY AS POSSIBLE.

Rapid treatment is essential. The immediate effects of poisoning depend on the dose of paraquat absorbed into the blood. Mild poisoning occurs at <20 mg paraquat ion/kg body weight and the effects are vomiting and diarrhoea.

Moderate to severe poisoning occurs at 20-30 mg paraquat ion/kg body weight

and the effects are vomiting, abdominal discomfort, soreness and inflammation of the mouth, throat and oesophagus, difficulty in swallowing and, later, diarrhoea. Kidney and liver damage may appear 1-3 days after exposure. Can

cause death by a delayed proliferating fibrosis of the lung within 1-3 weeks.

Lethal poisoning occurs at >30 mg paraquat ion/kg body weight and the effects

are nausea and vomiting, and can cause death by multi-organ failure and

circulatory collapse within 48 hours.

Acute dermal LD50: LD50 (rat) 911 mg/kg for paraquat dichloride

LD50 (rabbit) 240 mg/kg for paraquat ion

May cause temporary damage to nails and a delay in the healing of cuts and

wounds.

Skin: Contact with the concentrate on skin will result in moderate irritation. Can

cause inflammation and, in severe cases, blistering of the skin.

Contamination of the nails may cause white spots or, in severe cases, cracking

and loss of the nail. Normal growth follows without delay. Intact skin is a

very effective barrier to paraquat. Damaged skin removes the barrier and

paraquat may be absorbed with effects as outlined above under ingestion.

Eye: Eye irritation may be delayed. May lead to ulceration of corneal and

conjunctival epithelium giving rise to secondary infection. Although healing

may be slow, the injury is superficial and with proper medical care will be

complete, even in severe cases.

Vapour inhalation: LC50 (rat) (4hr) 0.5 - 1.5 ug/1 for paraquat dichloride

Highly toxic if inhaled.

Nose bleeding and soreness of the throat may result from spray mist or dust

trapped on the nasal mucosa. Irritating to the respiratory system. Pulmonary

oedema may occur up to 48 hours after exposure and could prove fatal.

If the concentrate is allowed to dry out, solid paraquat dust can be created.

Paraquat dust is highly toxic (TLV 0.1 mg/m3) and should not be handled without

full respiratory protection.

This product contains a stench agent to give an offensive smell. This has

been done to reduce the likelihood of accidental ingestion. This stench

agent may cause headaches and nausea in some people when inhaled. The

presence of this offensive smell in the air does not necessarily indicate the

presence of paraquat.

Chronic oral toxicity: NOEL mg/kg for two years.

Chronic Exposure:

For Amitrole: Based on the results of animal studies, liver and thyroid

effects may result. In prolonged feeding studies with animals, effects on the

thyroid have been documented, including the formation of tumours.

Epidemiological studies of workers using amitrole in the field have been

inconclusive with respect to an increase in the incidence of a specific

cancer.

Data indicates no reproductive effects.

WorkSafe Australia has classified amitrole in the occupational environment as

a Carcinogen Category 3 substance. This means the substance is not

classifiable as to carcinogenicity to humans. IARC {International Agency for

Research on Cancer) has determined that the mechanism in rats and mice is

unlikely to occur in humans; hence amitrole has been classified by IARC as Cat

3, not classifiable as to carcinogenicity to humans.

Acceptable Daily Intake (ADI): 0.004 mg/kg/day.

NOEL: 0.45 mg/kg/day, the level determined to show no effects during long term exposure for the most sensitive indicators and the most sensitive species.

Other Species:

Birds: toxicity. LD50 for mallard duck is 199 mg/kg for paraquat dichloride.

LD50 for bobwhite quail is 175 mg/kg for paraquat dichloride.

Amitrole is not toxic to birds.

Fish: toxicity LC50 (96hr) for rainbow trout is 15 mg/L for paraquat dichloride

Amitrole is not toxic to fish.

Invertebrates: toxicity. EC50 (48hr) for daphnia is 1.2 mg/1 for paraquat dichloride.

Bees: Not toxic.

Arthropods: toxicity.

Earthworms:

Algae: ECr50 (72hr) for algae is 0.32 mg/L.

Accumulation:

25 TOXICITY SYMPTOMS:

Vomiting, nose bleed, diarrhoea, inflammation of the mouth, throat and oesophagus, difficulty in swallowing.

26 FIRST AID:

If SWALLOWED: RAPID TREATMENT IS ESSENTIAL IN CASE OF PARAQUAT POISONING.

Immediately transfer patient to nearest hospital or medical centre, warning

by telephone of the estimated time of arrival so that the start of treatment

is not delayed. If swallowed, do NOT induce vomiting; make every effort to prevent vomit from entering the lungs by careful placement of the patient.

Rinse mouth. A slurry of activated charcoal or clay (fuller's earth,

bentonite) may be administered by a trained person. Ingestion of activated

charcoal tablets, food, or even plain dirt, may be of benefit if absorbent

slurry cannot be given.

Wash out mouth with water. Do NOT give anything by mouth to a semiconscious or unconscious patient.

If in EYES: If in eyes, hold eyelids open and wash with copious amounts of water for at least 15 minutes. Seek medical advice immediately.

If on SKIN: Wash affected areas thoroughly with soap and water.

Remove contaminated clothing and launder before re-use.

Seek medical advice, but only after the exposed skin has been thoroughly

washed.

If INHALED: Remove patient to fresh air. See a doctor immediately

Advice to doctor: RAPID TREATMENT FOR PARAQUAT POISONING IS ESSENTIAL. Evacuation of the stomach, stomach washout and administration of adsorbents should be carried out as quickly as possible.

A booklet entitled 'Paraquat Poisoning, a practical guide to diagnosis, first

aid and hospital treatment1 (prepared by Syngenta} is available at major

hospitals or Poisons Information Centres, or contact the emergency number at

the end of this SDS.

TREATMENT: Wash out stomach and test urine and gastric aspirate (if clear) for

presence of paraquat. Give activated charcoal (100 g for adults or 2 g / kg

body weight for children) orally or via gastric tube, together with a suitable

purgative (200 mL of an aqueous solution of mannitol). Alternatively, 1 litre

of 15% aqueous suspension of Fuller's Earth or a 7% suspension of bentonite in

10% glycerol in water should be used if activated charcoal is unavailable.

Repeat administration of adsorbent plus purgative until adsorbent is seen in

the stools. This should normally take between 4 and 6 hours after the start of

treatment. NOTE: The use of gastric lavage without administration of an

adsorbent has not shown any clinical benefit. Do not use supplemental oxygen.

Treat skin irritation / damage symptomatically with daily review if

contaminated with concentrate as blistering and chemical burns may develop

over 1 to 3 days. If systemic toxicity is suspected, test for paraquat in

urine or blood and treat confirmed paraquat systemic toxicity as above.

OBTAIN IMMEDIATE MEDICAL ATTENTION.

SPEED IS ESSENTIAL.
