“…Although many previous studies have reported sorption outcomes for diverse organic compounds, − few studies have focused on emerging stormwater and roadway-derived contaminants despite their ubiquity and sometimes high concentrations. ,− Also, the high concentrations (e.g., milligrams per liter) frequently used to facilitate analytical detection in laboratory studies ,, often substantially exceed environmental concentrations.

We investigated the sorption and desorption of four representative roadway runoff-derived organic contaminants [1,3-diphenylguanidine (DPG), N,N-dicyclohexylmethylamine, 1-cyclohexyl-3-phenylurea, and hexa(methoxymethyl)melamine] with five soils. Isotherm data from batch studies were well fitted by the Freundlich model (R 2 = 0.855–0.999). For ionic contaminants, log K oc values were affected by pH. These contaminants also exhibited sorption–desorption hysteresis that increased at higher concentrations. Additionally, to reflect common stormwater treatment practices, a 40% compost/60% sand engineered geomedium was evaluated as a representative model sorbent. For this geomedium, the sorption of the primary roadway-derived contaminants listed above was evaluated along with seven additional stormwater contaminants, including neutral and cationic compounds. Sorption affinities varied across different contaminants, with the positively charged DPG (log K oc = 3.12–4.11) and N,N-dicyclohexylmethylamine (log K oc = 2.65–4.51) exhibiting the highest sorption potential compared to those of neutral compounds in all soils except for 726 Toledo soil. Weak log D ow and log K oc correlations indicated that specific interactions such as hydrogen bonding and electrostatic attraction often affected sorption, although sorption to the organic matter rich engineered geomedium was dominated by hydrophobic interactions. As commonly observed, sorption affinities were influenced by aspects of contaminant structural diversity and chemical properties that induced differing interaction mechanisms.

“…[1] However, several studies have shown that the use of neonicotinoid insecticides, such as imidacloprid, is a key factor for declining biodiversity of nontarget terrestrial insects. [2][3][4][5] In addition, imidacloprid residues affect soil properties, [6] soil organisms, [7][8][9] and take a threat to human health. [10] 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.…”

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.

“…Imidacloprid (IMI) is the most widely used neonicotinoid insecticide (Bass et al, 2015), but its high environmental migration ability makes it often detected in the water and soil environment, which poses a threat to environmental ecology (Morrissey et al, 2015). Previous studies showed that IMI prefers to bind with organic matter and mineral components in soil by hydrophobic partition, H-bonding, pore filling, cation-π electron donor-acceptor (EDA) interactions and electrostatic effects (Broznić et al, 2012;Satkowski et al, 2018;Zheng et al, 2021). However, there are few reports on the adsorption of complexes of Gt and DBC (Gt-DBC) for IMI.…”

Dissolved black carbon (DBC) is an important component of natural dissolved organic matter and can bind to iron minerals to form DBC-mineral complexes by adsorption and coprecipitation. However, reports regarding the difference in physicochemical properties between adsorbed and coprecipitated DBC-mineral complexes and their sorption capacity for polar organic pollutants are limited. Herein, goethite (Gt) and the adsorbed and coprecipitated complexes of DBC with Gt (SGt-DBC and CGt-DBC) were prepared, and their physicochemical properties and adsorption capacity for polar imidacloprid (IMI) were determined. The results showed that DBC could efficiently bind to Gt by coprecipitation or adsorption, leading to the aggregation of Gt particles, decreasing SSA, and increasing microporous volume, O-containing functional groups and negative charges. A greater effect was observed in CGt-DBC samples than SGt-DBC samples. CGt-DBC samples could more efficiently adsorb IMI than SGt-DBC samples, and CGt-DBC samples obtained the greatest Qmax with 68.4 mg/kg. The sorption mechanisms mainly involved hydrophobic partitioning, H-bonding, cation-π and p/π-π electron donor-acceptor interactions and electrostatic interactions. Additionally, the greater solution pH and Na+ concentration facilitated IMI adsorption on Gt and Gt-DBC samples; however, the Ca2+ solution obtained the opposite result. This effect on IMI adsorption was more pronounced for CGt-DBC samples. Therefore, the findings of this study provide a deep understanding of the interactions between Gt and DBC by adsorption and coprecipitation and their effect on the sorption of organic pollutants in natural soil and water environments.
