Environmental fate:
Animals:[¹⁴C-acid]-bioallethrin administered in rats with a single dose of either 200 or 100 mg/ kg b.w. was readily eliminated in the urine and faeces of all dose groups within 2-3 days after treatment.Soil:[¹⁴C-alcohol]-bioallethrin degrades in pH 5 buffer to allethrolene, dihydroxyallethrolene, CO₂ and a number of small yield polar products as the result of photochemical processes. Cis/trans isomerisation was
