Environmental Profile
Ecotoxicology:
Algae: EC50 0.02-13.6 mg/l for three freshwater algae and two diatom species.Bees:Not toxic to bees; LD50 (contact and oral) >100µg/bee.Birds:Acute oral LD50 for Japanese quail 2223, bobwhite quail 2825, mallard ducks >2510, Pekin ducks >6000 mg/kg.

EC50 (96 h) for mysid shrimp (Mysidopsis bahia) 0.5 mg/l.Other beneficial spp.:Under field conditions, not expected to have any significant impact.
Environmental fate:
Animals:After oral administration to the rat, propiconazole is rapidly absorbed and also rapidly and almost completely eliminated with urine and faeces. Residues in tissues were generally low and there was no evidence for accumulation or retention of propiconazolSoil: DT50 in aerobic soils (25 °C) 40-70 d. The main degradation pathways are hydroxylation of the propyl side-chain and the dioxolane ring, and finally formation of 1,2,4-triazole. Koc (ads) 950 ml/g, immobile in soil.Plant:Degradation proceeds through hydroxylation of the n-propyl side-chain and deketalisation of the dioxolan ring. After cleavage of triazole, triazole-alanine is formed as the main metabolite. Metabolites are conjugated mostly as glucosides.
