“…For example, a recent study has found that flufiprole, an alternative product of fipronil, can be transformed into fipronil in environmental and biotransformation systems. 60 In China, flufiprole has been widely used since fipronil was banned from rice and other crops. It is not clear whether flufiprole in the environment is another source of human fipronil exposure, which requires further follow-up research.…”

Fipronil, as an emerging phenylpyrazole insecticide, is ubiquitous in the environment and food due to its broad spectrum and persistent characteristics, but the research on pathways of human exposure to fipronil and the associated health risk is relatively unclear. In this regard, we summarize potential human exposures to fipronil through ingestion and inhalation, as well as results of human biomonitoring studies. This scientific information will contribute to future assessment of fipronil exposure and subsequent characterization of human health risks. Additionally, this Perspective highlights the lack of epidemiological studies and total diet studies for the general population on fipronil.

“…Pesticide pollution of irrigation water can negatively impact biodiversity (Pandey et al, 2020 ), and direct contact with applied pesticides can adversely affect nontarget species, soils, and waterways (Barbieri et al, 2021 ). Some examples of harmful impacts of pesticides on nontarget species include inhibition of enzyme functions, bioaccumulation in and damage to fish tissues (Clasen et al, 2018 ; Gao et al, 2020 ; Rossi et al, 2020 ), disturbances in the swimming behaviors of fish and amphibians (Shuman‐Goodier et al, 2017 ), hormonal disruption in frogs (Shuman‐Goodier et al, 2017 ), the restriction of development and biological activities of beetles (Khan et al, 2018 ), mortality and changed feeding behavior of spiders (Tahir et al, 2019 ), mortality of bees and wasps (Cheng et al, 2018 ; Yasuda et al, 2017 ), weight loss and shifts in enzymatic activity of earthworms (Rico et al, 2016 ), and reduction of soil microbe populations (Nicomrat et al, 2016 ). Optimal use of pesticides in paddy farming supports beneficial species, leading to ecosystem services that limit pests, while maximizing production (Horgan, 2017 ).…”

Rice paddies are unique ecosystems that provide rich wetland habitat. Their enduring existence across vast stretches of land has led them to evolve into unique systems serving a diverse assemblage of organisms and sustaining a staple grain for many people. With food demand rising, agricultural intensification through agrochemical application is a common practice used to boost food production in developing countries, including Sri Lanka. The aim of the present study was to assess the concentration of pesticide residues in water in rice ecosystems and discover their potential impacts on both environmental health and the most common fauna groups across a cropping year in Sri Lanka. A total of 270 water samples from waters associated with paddy fields within a watershed were analyzed for 20 commonly used pesticides; in addition, local farm holders were surveyed to assess pesticide usage details in three selected paddy tracts. We then used the Cornell University environmental impact quotient (EIQ) calculator and the ECOTOX Knowledgebase to determine the exposure risk associated with individual pesticides relative to their application rates and aquatic concentrations. Survey results demonstrate that several pesticides were overapplied at rates 1.2–11 times the recommended application, and the EIQ demonstrated high environmental risk of two of the agrochemicals detected, 2‐methyl‐4‐chlorophenoxyacetic and diazinon. Fish, amphibians, insects, and beetles were found to have a wide range of potential adverse outcomes from exposure to diazinon, captan, thiamethoxam, and chlorantraniliprole. To balance the trade‐offs between food security and ecosystem sustainability, the present study recommends that adoption of quantifiable environmental health indicators be considered as part of the national policy regulating pesticide use.

“…Fipronil impacts not only terrestrial, but also aquatic organisms (Doran et al, 2009). Harm to nontarget species of invertebrates that spend some part of their life in water are an overriding concerns in regard to the contamination of environments with fipronil (Bonmatin et al, 2015; Gao et al, 2020). Previous studies reported that fipronil is toxic to fish and aquatic invertebrates such as shrimp and water fleas (Bonmatin et al, 2014; Qu, Ma, Liu, Gao, Wang et al, 2016).…”

“…Previous studies reported that fipronil is toxic to fish and aquatic invertebrates such as shrimp and water fleas (Bonmatin et al, 2014; Qu, Ma, Liu, Gao, Wang et al, 2016). Toxicity varies across species (Gao et al, 2020). For example, the LC 50 for fipronil in African clawed frog ( X. laevis ) tadpoles was 850 μg/L; the LC 50 s for bluegill sunfish ( Lepomis macrochirus ) and rainbow trout ( Oncorhynchus mykiss ) were 85 and 248 μg/L, respectively (Wang et al, 2019).…”

Fipronil use and associated effects on hematological and biochemical parameters of blue land crab (Cardisoma guanhumi Latreille): Ecological implication

et al. 2021

Fipronil is used to control pests to improve farm yield, however, indiscriminate use of fipronil has been reported to endanger crabs leading to their extinction. Therefore, this study investigated the impact of fipronil on several hematological and biochemical parameters of blue land crabs. We exposed blue land crabs to either fipronil or to a control treatment; fipronil reduced the protein content of the crab and also led to hematological and oxidative damages to the crabs' oxy‐hemocyanin. Based on our results, there is need for guided use of agrochemicals such as fipronil to avoid/reduce their adverse effects on economically important species such as crabs.
