Fipronil insecticide dissipated in California rice fields, producing half‐lives of 10.5 to 125h in water and 44.5 to 533 h in soil, depending on the formulation applied and the resulting differences in water solubility. The major degradation products were desthiofipronil in water and fipronil‐sulfide in soil, while the sulfone and amide were less abundant. Fipronil was photolyzed rapidly to desthiofipronil in deionized water in the laboratory (t½ = 7.97–9.42 h) and even faster in the presence… 
The fate of fipronil in modular estuarine mesocosms.
TLDR
Loss was apparently first-order in fipronil, although there appeared to be a change in the removal mechanism after 96 h that corresponded to a dramatic slowdown in its disappearance.
Persistence of fipronil and its metabolites in soil under field conditions
TLDR
Dissipation followed a biphasic first-order kinetics with half-life values of 10.81 and 9.97 days for fipronil alone and 8.14 and 13.05 days along with metabolites in soil at (T1) and (T2) treatments, respectively.
Utilization of common ditch vegetation in the reduction of fipronil and its sulfone metabolite.
TLDR
D ditch mesocosms planted with monospecific stands of common emergent wetland vegetation were used to determine if certain plant species were more proficient in fipronil mitigation to examine potential changes in reduction capacities.
Fipronil and two of its transformation products in water and European eel from the river Elbe.
Persistence of fipronil and its metabolites in sandy loam and clay loam soils under laboratory conditions.
Fipronil: environmental fate, ecotoxicology, and human health concerns.
TLDR
The indications are that fipronil may be incompatible with locust IPM; hence, this possibility requires further urgent investigation, and great care should be taken in using these formulations where they may impact any of these endangered wildlife groups.

Kinetics and Mechanisms of Abiotic Degradation of Fipronil (Hydrolysis and Photolysis)
The abiotic degradation of fipronil (compound I), a phenylpyrazole insecticide, was studied in aqueous solution and on the surface of two soils from Niger (Saguia and Banizoumbou) and one
Behaviour of fipronil in soil under Sahelian Plain field conditions
TLDR
The behaviour of fipronil, a phenylpyrazole insecticide used for locust control, was studied under sub-Saharan conditions in soils of the Niamey region of Niger with rapid initial decrease and rapid formation for the most part of a photodegradate.

TLDR
It is found that fipronil contains a trifluoromethylsulfinyl moiety that is unique among the agrochemicals and therefore presumably important in its outstanding performance, and unexpectedly undergoes a novel and facile photoextrusion reaction on plants upon exposure to sunlight.
Actions of the insecticide fipronil, on dieldrin‐sensitive and ‐resistant GABA receptors of Drosophila melanogaster
TLDR
Homo‐oligomeric RDL receptors should facilitate detailed studies of the molecular basis of convulsant/ insecticide antagonist actions on GABA receptors, as the mutation A302→S reduces the potency of both fipronil and picrotoxinin.

Action of phenylpyrazole insecticides at the GABA-gated chloride channel
TLDR
The insecticidal phenylpyrazoles appear to block the GABA-gated chloride channel with higher potency for a site in house fly brain than in mouse brain, thereby providing useful selective toxicity.
