Section 2
SECTION 2: Hazards identification
Main hazard: Very toxic to aquatic organisms, may cause long term adverse effects in the aquatic environment. Poisonous if swallowed. May irritate the nose, skin, throat and eyes. Do not contaminate rivers, streams or dams. Do not apply within the root zone of desirable vegetation. Flammability Non-flammable. Bromacil Combustible – stable up to the melting point. Chemical hazard Bromacil
Most important adverse effects
No hazards to be especially mentioned. Terbuthylazine: R 22. Harmful if swallowed. Biological hazard: Highly toxic to algae. Very toxic to aquatic organisms, may cause long term adverse effects in the aquatic environment. Bromacil can seep or leach through soil and can enter ground water which might be used as drinking water. Correct use rates by geographical area and proper mixing-loading site precautions and procedures must be followed to minimize potential bromacil movement into ground water. Reproductive hazard: Bromacil did not affect the reproduction and lactation performance of rats fed 0 or 12, 5 mg/kg/day for 3 generations. Eye effects eyes Bromacil – Mild eye and skin irritant. Non-sensitizing to skin Terbuthylazine: No skin or eye irritation; not a skin sensitizer.
Potential health effects
skin Bromacil – Dermal LD50 (rat) > 5000 mg/kg; (Non-irritating to skin and eyes). Terbuthylazine - Dermal LD50 (rat) > 3000 mg/kg; (Non-irritant to eyes and slightly to skin of rabbits) ingestion Bromacil – Oral LD50 (rat) = 5175 mg/kg Terbuthylazine – Oral LD50 (rat) = 2000 mg/kg. inhalation Bromacil – LC50 (4h) for rats> 4.8 mg/ℓ air; Irritating 2 to respiratory system. Avoid inhalation of dust. Terbuthylazine – LC50 (4 h) for rats > 3.51 mg/ℓ air. Carcinogenicity: Although bromacil has not been determined to cause cancer, it is considered by the EPA to be a possible human carcinogen because there is some limited or uncertain evidence that bromacil causes cancer in animals receiving high doses of the chemical over the course of their lifetimes. There was no evidence of carcinogenicity in rats fed 12.5 mg/kg/day of bromacil. Mutagenicity: Several mutagenic screening tests have not found bromacil to be mutagenic. Neurotoxicity: Not available.
