22. TOXICITY:

Poison schedule - S7
Summary: Very dangerous. Can kill if absorbed by skin contact or inhaled or swallowed. Repeated minor exposure may have a cumulative poisoning effect. Do not touch or rub eyes, nose or mouth with hand when handling granules. Avoid contact with eyes and skin. Do not inhale dust.
Details:
Poison schedule - S7
Mammalian toxicity - High toxicity.
Acute oral LD50 - 1.3-6.3mg/kg
Acute dermal LD50 - mg/kg
Skin - Not irritating.
Eye - Mildly irritating
Main exposure routes - Handling concentrate.
Vapour inhalation - LC50 - > mg/L air (rat).
Chronic oral toxicity NOEL - 0.0025 mg/kg/day for two years.
Not carcinogenic, mutagenic or teratogenic (i.e. Does not cause cancer or reproductive problems).
Acceptable Daily Intake (ADI) -0.0002 mg/kg/day.
Fate in humans and animals: In rats given a single oral dose of Terbufos, 10% remained in the liver 6 hours after dosing. Breakdown products were found in the kidney 12 hours after dosing. Of the original dose administered, 83% was excreted in the urine within 7 days after dosing, and 3.5% was found in the faeces. Terbufos and its metabolites
did not accumulate in tissues. No detectable residues have been found in the eggs, milk, or body tissues of animals (hens and cows) fed very high dietary doses of Terbufos and its cholinesterase inhibiting metabolites.

23. TOXICITY SYMPTOMS:

Signs and symptoms associated with mild exposures to organophosphate and carbamate pesticides include: headache, fatigue, dizziness, loss of appetite with nausea, stomach cramps and diarrhoea; blurred vision associated with excessive tearing; contracted pupils of the
eye; excessive sweating and salivation; slowed heartbeat, often fewer than 50 per minute; rippling of surface muscles just under the skin. These symptoms may be mistaken for those of flu, heat stroke or heat exhaustion, or upset stomach. Moderately severe organophosphate and carbamate insecticide poisoning cases exhibit all the signs and
symptoms found in mild poisonings, but in addition, the victim: is unable to walk; often complains of chest discomfort and tightness; exhibits marked constriction of the pupils (pinpoint pupils); exhibits muscle twitching; has involuntary urination and bowel movement. Severe poisonings are indicated by incontinence, unconsciousness and seizures.

24. FIRST AID:

Call Poisons Information Centre: 13 1126 from anywhere in Australia, (0800 764 766 in New Zealand)
If swallowed, splashed on the skin or inhaled, contact a Poisons Information Centre or a doctor at once. Remove any contaminated clothing and wash skin thoroughly. If swallowed, use of activated charcoal may be advised.
Inhalation: If inhaled, contact a Poisons Information Centre or a doctor at once.
Skin Contact: Quickly and gently brush away excess solids. Seek urgent medical attention. Remove contaminated clothing, shoes and leather goods (e.g. watchbands, belts). Flush contaminated area with lukewarm, gently flowing water for at least 60 minutes, by the clock. DO NOT INTERRUPT FLUSHING. If necessary, keep emergency vehicle waiting (show paramedics this SDS and take their advice). If breathing has stopped, trained personnel should begin artificial respiration or, if the heart has stopped, cardiopulmonary resuscitation (CPR) immediately.
Eye Contact: Quickly and gently brush particles from eyes. May be toxic or irritating by eye contact. If irritation does occur, flush contaminated eye(s) with lukewarm, gently flowing water for 5 minutes or until the product is removed. Obtain medical advice if irritation becomes painful or lasts more than a few minutes.
Ingestion: If swallowed, rinse mouth thoroughly with water and contact a Poisons Information Centre, or call a doctor at once. Give activated charcoal if instructed.
If you are exposed to organophosphate for more than 30 hours per month then levels of acetylcholinesterase enzyme should be regularly checked. If levels drop below 60% of normal then work with organophosphates should stop until levels improve. This may take several weeks.

25. PROTECTIVE CLOTHING:

When using the product wear cotton overalls buttoned to the neck and wrist, a washable hat, elbow length PVC gloves, impervious footwear and half facepiece respirator with dust cartridge or canister.

26 RE ENTRY PERIODS and OTHER SAFETY ISSUES:

Avoid entering enclosed spaces such as glasshouses for 48 hours after applicaation.

28. ENVIRONMENTAL FATE:

Summary - Dangerous to bees.
Birds - toxic. LD50 is 145-185 mg/kg.
Fish - Extremely toxic. LC50 is 0.01-0.004 mg/L.
Invertebrates - Extremely toxic. LC50 is ppm
Bees - Non toxic.
It has a half life in soil of 1-20 days.
Half life in water - 0.2-4 days.
It has an EPA classification for soil mobility that ranges from
Ground water contamination - unlikely. Low likelihood of leaching. Low likelihood of runoff.
Accumulation in milk and tissues.
pH stability - Unstable at ph>5
Photolysis rate - 21-28 days.
Hydrolysis half life - 4.5-8.5 days at pH 5-9.
Biodegradation rate - Slow to readily and rapidly biodegradable in the environment.
Breakdown in soil and groundwater: Terbufos is low to moderately persistent in soil. It is rapidly converted to its metabolites which tend to persist in the soil and may be detected at harvest time. Terbufos and its metabolites quickly degrade during the first 15 to 30 days after application, then gradually stabilize. Only 3% of the original application
stayed in field-study soils after 1 month, with 1.5% of the chemical present after 60 days..
Breakdown in water: Terbufos hydrolyses rapidly. At a concentration of 4.6 mg/L, its hydrolysis half-lives were 4.5, 5.5, and 8.5 days at pH 5, 7, and 9 respectively. Formaldehyde was the major degradate detected.
Breakdown in vegetation: Terbufos moves from the soil into plants, where it is broken down rapidly. Little of the parent compound is found in plants.
Negligable bio-accumulation potential.

Rapidly absorbed and metabolised then excreted in urine mainly.
Very resistant to leaching.
Strongly adsorbed and not mobile in soil.
