Decomposition: May produce toxic fumes such as hydrogen bromide and carbon oxides on excessive heating
Acute Toxicity: Fatal by oral (LD50 35 mg/kg) and inhalation (LC50 0.38 mg/L) exposure in rats
Skin and Eye Contact: Mild skin irritant; not a sensitizer in tested animals; may cause transient eye irritation
Chronic Exposure: Studies point to effects on nervous system, weight loss, and liver changes at sublethal doses
Other Effects: Not mutagenic in the Ames test; long-term carcinogenicity unconfirmed in most available studies
Symptoms: Convulsions, tremors, muscle weakness, headache, vomiting, incoordination, agitation
Aquatic Toxicity: Highly toxic to fish (LC50 in rainbow trout: 0.063 mg/L), daphnia, and many aquatic invertebrates
Avian Toxicity: Moderate toxicity to some bird species (LD50 quail: 405 mg/kg)
Bee Toxicity: Not considered highly toxic on contact, risk mainly through drift or contaminated water
