Bifenthrin was non-irritating when applied to the skin of rabbits and practically non-irritating to the eyes of rabbits. The high toxicity of bifenthrin in nontarget organisms has resulted in bifenthrin being classified as a restricted use pesticide by the US Environmental Protection Agency. They also appear to inhibit ATPases. Several studies of urban creek sediments in California have detected bifenthrin in the sediment.

EXTOXNET, Extension Toxicology Network, Pesticide Information Profile, http://extoxnet.orst.edu/pips/bifenthr.htm, Nanobiopesticide perspectives for protection and nutrition of plants, Nano-Biopesticides Today and Future Perspectives, One the main concerns of pesticide nanoformulation is whether these formulations can be evaluated with the existing pesticide regulatory framework.

The soil half-life of bifenthrin ranged from 106 to 147 days when the soil was exposed to sunlight. barely above detection. Bifenthrin is neurotoxic and targets voltage-gated sodium channels in neurons. Symptoms less frequently reported include blurred vision, heart palpitations and tightness in The acute reference dose (RfD) for bifenthrin is 0.328
The strong adsorption of bifenthrin to soil can limit its availability to certain aquatic organisms, mitigating toxicity.

Metabolism involves hydrolysis of the central ester bond, which reduces toxicity, oxidation of some groups, and conjugation with glycine, sulfate, or glucuronide. Researchers fed mice technical-grade bifenthrin for at least 20 months at doses of 0, 50, 200, 500, or 600 ppm. Prognosis is usually good to excellent in most species, but may be poorer in cats. its tendency to bind to soil and its low water solubility. Hideo Kaneko, in Hayes' Handbook of Pesticide Toxicology (Third Edition), 2010. Huntington, England. Paresthesia was the most commonly reported symptom from dermal exposure in occupational studies involving pyrethroids. LD50 is generally expressed as the dose in Exposure: Effects of bifenthrin on human health and the environment depend on how much Kay et al. The toxicity of fipronil, imidacloprid, and bifenthrin on Penaeus monodon (a species of shrimp) in northeastern Australia was recently reported (Hook et al., 2018). Propofol IV infusion or gas anesthesia have also been used in some cases. Analyses were extended for an additional 85 days following cessation of dosing (depuration phase). 10-day LC. The aerobic half-life of bifenthrin in soil ranges from 97-250 days, depending on soil type. On the other hand, the majority of urinary metabolites were ester-cleaved products such as 4-OH-BP acid (4-hydroxy-2-methyl-3-phenylbenzoic acid), BP acid (2-methyl-3-phenyl-benzoic acid), 4-OH-BP alcohol (4-hydroxy-2-methyl-3-phenylbenzyl alcohol), dimethoxy-BP acid, 4-methoxy BP acid, dimethoxy BP alcohol, BP alcohol, TFP acid [3-(2-chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethyl-cyclopropanecarboxylic acid], and cis- and trans-hydroxymethyl TFP acid.

Detection of pyrethrins/pyrethroids in biological samples is not often available, and if available, can confirm exposure but not toxicosis.
