In this study, the results obtained for the analysis of fipronil residue in egg using a Thermo Scientific triple quadrupole GC-MS system are reported. System performance was tested using full scan acquisition and simple instrumental setup. The experiments performed focused on assessing the sensitivity, linearity, selectivity and analytical precision for the analysis of fipronil and its. Fipronil degrades slowly on vegetation (half-life of 7.3 months depending on substrate and conditions) and relatively slowly in soil and in water (half-life can accelerate to 36 hours in water and sunlight). Desulfinyl fipronil and fipronil sulfone are two of the chemicals left over after fipronil decays Fipronil is a potent insecticide used for control of termites, fleas, roaches, ants, and other pests. We measured fipronil, fipronil sulfide, and desulfinyl fipronil concentrations in indoor and outdoor dust from 24 residences in Austin, Texas. At least one of these three fipronil compounds was detected in every sample. Fipronil accounted for most of the total fipronil (T-fipronil; fipronil. Fipronil also caused uncoupling in succinate-energized mitochondria and calcium efflux. The metabolites sulfone and desulfinyl also acted as mitochondrial inhibitors and uncouplers and caused calcium efflux, but with different potencies, being the sulfone the more potent one Fipronil verstoort de werking van het GABA-complex en het transport van chloride-ionen in insecten en teken.

Fipronil and the desulfinyl product are very similar in toxicity with LD 50 values within about 2-fold of each other for both houseflies and mice. The cytochrome P450 oxidase inhibitor piperonyl butoxide increases the insecticidal activity of fipronil by 7-fold without affecting that of the desulfinyl derivative, suggesting that the latter compound is not readily metabolized The major fipronil metabolites are fipronil-sulfone and fipronil-sulfide. A major photodegradation product is fipronil-desulfinyl, which can be ingested by animals and also appears following oral exposure or injection. All three products appear to contribute to the toxicity of fipronil. Therefore, analyses should include all four substances Fipronil Fipronil-desulfinyl Fig. 2.

Fipronil is metabolized into many metabolites including sulfone, sulphide, and desulfinyl. However, it has been demonstrated the primary metabolite of fipronil, fipronil sulfone, actually has a much greater affinity for these channels in mammals than those in insects indicating potential detrimental effects of the break-down products to non-target organisms [ 6 ] Notably, fipronil desulfinyl caused more significant changes in gene expression than fipronil did. Crabs exposed to the insecticide and its byproduct fipronil desulfinyl grew more quickly than those in the control group. While this may sound like a good thing, crabs must molt — lose their exoskeleton — to grow

Its activity is based on blocking the g-aminobutryic acid (GABA) receptor site on GABA-gated chloride channels. Fipronil binds more tightly to this receptor in insects than in. A multivariate kinetic model of aqueous fipronil photodegradation was developed as a function of dissolved organic matter (DOM), bicarbonate, and nitrate at concentrations that bracket those commonly observed in natural waters (ca. 0−10 mg/L). Several pathways were available for fipronil photodegradation in this system, including direct photolysis and indirect photooxidation by species.

  1. Fipronil degrades on soil surfaces by ultraviolet radiation and rapidly in water when exposed to UV light to form fipronil-desulfinyl. Under these conditions, fipronil has a half-life of 34 days in loamy soil and 4 to 12 hours in water. Fipronil is stable to hydrolysis at pH 5 and pH 7. However, it degrades in alkalin

  3. Fipronil is a phenylpyrrole insecticide that is widely used to control a variety of pests associated with crops in both agricultural and non-agricultural areas[1]. In the natural environment, fipronil can degrade to fipronil-desulfinyl, fipronil-sulfone, or fipronil-sulfide by photolysis, oxidation, or reduction
  4. Fipronil is an insecticide extensively used to control pests in crops and animals. Desulfinyl also caused uncoupling in succinate-energized mitochondria and calcium efflux. The metabolitesulfone also acted as mitochondrial inhibitors and uncouplers and caused calcium efflux, but inlower concentrations (0.5 to 5 μM)

  6. Desulfinyl fipronil, the major photodegradation product, which is not chiral, was detected at <1% of each parent compound in test solutions after 48 h. Separate toxicity tests with desulfinyl fipronil found a >20‐fold higher LC50 (355 ± 9.3 μg/L) compared to the fipronil racemate, suggesting lower adverse effects to C. dubia as a result of fipronil photolysis

Endocrine disrupting compounds (EDCs) are now widely established to be present in the environment at concentrations capable of affecting wild organisms. Although many studies have been conducted in fish, less is known about effects in invertebrates such as decapod crustaceans. Decapods are exposed to low concentrations of EDCs that may cause infertility, decreased growth, and developmental.. The team then added a range of concentrations of the insecticide fipronil or one of four associated fipronil degradate compounds - sulfone, sulfide, desulfinyl and amide - and observed the effects on macroinvertebrates. Scientists found these degradates to be as toxic, if not more so than fipronil Fipronil is a broad spectrum phenylpyrazole compound which is recently used in field condition for the control of the tick, mites, flea and flies population in domestic animals and pets. It is used more often in organised cattle farms to avoid fly menace and concurrently reduce tick infestation
