“…Pesticides and other organic contaminants are increasingly being identified as a key stressor shaping benthic communities across the United States (Waite et al 2021) and in Europe (Liess et al 2021;Beketov et al 2013). A nationwide study recently found agricultural pesticide levels in 74 rivers across the United States above ecologically relevant thresholds (Stackpoole et al 2021). Pesticides have also been consistently reported as a primary stressor or above toxicity levels in urban centers across the United States (Brown et al 2009;Waite et al 2019;Nowell et al 2021).…”

Biological communities in freshwater streams are often impaired by multiple stressors (e.g., flow or water quality) originating from anthropogenic activities such as urbanization, agriculture, or energy extraction. Restoration efforts in the Chesapeake Bay watershed, USA seek to improve biological conditions in 10% of freshwater tributaries and to protect the biological integrity of existing healthy watersheds. To achieve these goals, resource managers need to better understand which stressors are most likely driving biological impairment. Our study addressed this knowledge gap through two approaches: 1) reviewing and synthesizing published multi-stressor studies, and 2) examining 303(d) listed impairments linked to biological impairment as identified by jurisdiction regulatory agencies (the states within the watershed and the District of Columbia). Results identified geomorphology (i.e., physical habitat), salinity, and toxic contaminants as important for explaining variability in benthic community metrics in the literature review. Geomorphology (i.e., physical habitat and sediment), salinity, and nutrients were the most reported stressors in the jurisdictional impairment analysis. Salinity is likely a major stressor in urban and mining settings, whereas geomorphology was commonly reported in agricultural settings. Toxic contaminants, such as pesticides, were rarely measured; more research is needed to quantify the extent of their effects in the region. Flow alteration was also highlighted as an important urban stressor in the literature review but was rarely measured in the literature or reported by jurisdictions as a cause of impairment. These results can be used to prioritize stressor monitoring by managers, and to improve stressor identification methods for identifying causes of biological impairment.

“…However, to date, neonicotinoids are still used in approximately 120 countries worldwide (Craddock et al 2019). In the USA, they are still extensively used (Stackpoole et al 2021), and the Environmental Protection Agency (EPA) scheduled a Review Process for the risk assessment of several neonicotinoids, such as imidacloprid, that will end in 2024 (EPA docket ID: EPA-HQ- OPP-2008-0844).…”

Despite several restrictions to their use, neonicotinoid insecticides are still widely employed worldwide. Residual sub-lethal amounts of these chemicals can have detrimental effects on the behavior of non-target insects. Toxic effects on economically important species such as bees have been widely documented, but less is known about their toxic action on other social insects, such as ants. In this study, we assessed the effect of different sub-lethal doses of the neonicotinoid imidacloprid on the ability of colonies of the invasive ant Lasius neglectus to select the most profitable resource. We used Y-shaped mazes having an imidacloprid-polluted or an unpolluted sucrose solution on the two branches. Two sucrose (0.1 M, 0.5 M) and two imidacloprid (1 μg/ml, 10 μg/ml) concentrations were used. In parallel, we evaluated the marking activity of foragers who fed on the same solutions. We found that the 0.1 M sugar solution polluted with 1 μg/ml imidacloprid was significantly more frequently selected in binary choices experiments than the unpolluted resource. Moreover, the ingestion of the same combination of sugar and imidacloprid significantly increased the marking rate of foragers. The higher concentration of the pollutant had lower effects, probably because of the hormesis phenomenon. Results suggest that the lower sub-lethal dose of imidacloprid can lead ants to select again the polluted resource. This “active” selection of the pollutant may magnify the negative effects on the colonies. Due to their ecological role, any impairment of ant survival or behavior may have detrimental cascade effects on the whole ecosystem.

“…With its widespread use and its solubility, imidacloprid is commonly detected in rivers all over the world, such as in China, Indian, Span, USA and England. [15][16][17][18][19][20] The presence of imidacloprid in water poses a treatment challenge due to its recalcitrance to biodegradation, and its persistence makes it hard to be eliminated through traditional wastewater treatment plants. Imidacloprid has an aerobic and anaerobic half-life of 997 and 27.1 days, respectively.…”

“…Imidacloprid is highly soluble in water, and there is a high possibility of it to enter into aquatic ecosystems through runoff, and thus potentially may pose risks to aquatic organisms, [11–12] such as dropping the survival of invertebrates, [13] inducing cyanobacteria blooms [14] and so on. With its widespread use and its solubility, imidacloprid is commonly detected in rivers all over the world, such as in China, Indian, Span, USA and England [15–20] …”

Preparation of BiVO₄/RGO‐TNT Nanomaterials for Efficient and Recyclable Photocatalysis of Imidacloprid Insecticide

The photocatalytic composites based on BiVO4, TiO2 nanotubes (TNT) and reduced graphene oxide (RGO) were synthesized by a one‐step hydrothermal synthesis method. The properties and structures of the samples were characterized by SEM, XRD, UV‐Vis DRS, Raman spectroscopy, photoluminescence spectroscopy and XPS. The effects of RGO‐TNT loading, pH, and dosage of catalysts on degradation efficiency were tested. The best removal results were occured on the condition that loading amount of RGO‐TNT was 10 %, solution pH 10, and catalyst dosage was 1.4 g L−1. The obtained ternary composite with 10 wt% RGO‐TNT exhibited a significant enhancement in photocatalytic efficiency due to the lower band gap with enhanced light absorption and a suppression in the recombination rates of the photogenerated charge carriers, and about 73 % of imidacloprid was degraded within 30 min under UV irradiation. Furthermore, BiVO4/RGO‐TNT‐10 can be reused for 6 times without obvious catalysis loss. Trapping experiments showed that hydroxyl radicals were the main active species in the imidacloprid photocatalytic degradation, and a possible photocatalytic mechanism was proposed based on the results of trapping experiments.
