Abstract
Soil is the largest terrestrial carbon pool, and adsorption of soil organic matter (SOM) by ferrihydrite is an essential geochemical process for preservation of organic carbon in soil. Freshly formed gel-like ferrihydrite and seasonally dried dense ferrihydrite are two typical morphologies of ferrihydrite in soil. However, the differences in SOM adsorption by gel-like ferrihydrite and dense ferrihydrite and the underlying mechanisms are unknown. In this study, adsorption of eight SOM or SOM-like compounds by gel-like ferrihydrite and dense ferrihydrite were compared. It was observed that the adsorption capacity of SOM by gel-like ferrihydrite (e.g., 304 mg C/g) was two orders of magnitude higher than that by dense ferrihydrite (e.g., 3.44 mg C/g). SOM adsorbed by the nanosized gel-like ferrihydrite could be mainly attributed to the heteroaggregation, confirmed by not only the TEM images but also the positive linear correlation between adsorption capacity and molecular weight of SOM. However, SOM adsorbed by the microsized dense ferrihydrite should be attributed to the pore-filling adsorption with molecular sieve effects, confirmed by the negative linear correlation between adsorption capacity and molecular weight of SOM. The obtained results could provide a new insight to understand the preservation of organic carbon by ferrihydrite in soil.

Abstract
Gibberellic acid (GA3), a widely used phytohormone, is easily transformed into more toxic products. The soil and groundwater environment are an important sink for GA3, but its transformation catalyzed by soil minerals has not been studied. In this study, the transformation kinetics and mechanism of GA3 with ferrihydrite (Fh) were examined through kinetic batch experiments, microscopic-spectroscopic investigation and mathematical modeling. The results showed that rapid adsorption of GA3 on Fh occurred in the first 4 h, followed by a catalytic pseudo-first-order transformation of the parent compound and products generation (4 h-30 d). Fh predominantly enhanced the transformation of GA3 into Iso-GA3 which was further hydrolyzed into OH-GA3, in which adsorption was a prerequisite for transformation. The catalytic transformation likely resulted from the surface hydroxy of Fh, which not only stabilized the transformation intermediates by forming surface complexes with the carboxyl group of GA3 and its products, but also served as a powerful nucleophile to attack the γ-lactone of GA3 and Iso-GA3. Based on the catalytic isomerization and hydrolysis mechanism of GA3 with Fh, a novel adsorption-transformation multi-step kinetic conceptual model and mathematical model were developed. This model fitted the measured data well (R2 > 0.97) and the fitted parameters suggested that the transformation rate constants of the transformation of GA3 into Iso-GA3 and the transformation of Iso-GA3 into OH-GA3 were facilitated with Fh by ∼26 and ∼9 times, respectively. The multi-step kinetic model has great potential in simulating GA3 fate in soil and groundwater to assess its environmental health risk.

Abstract
Given the ubiquitous mineral (e.g., clays and iron oxides) playing critical roles in impacting the fate of antibiotics in the subsurface environment, the effects of two mineral colloids (i.e., ferrihydrite and montmorillonite) on tetracycline (TC, a representative of antibiotic) transport in sand columns were investigated in this study. Interestingly, the results clearly showed that ferrihydrite colloids inhibited TC transport, while montmorillonite colloids enhanced TC mobility under neutral conditions (pH 7.0). This phenomenon resulted from the positively charged ferrihydrite colloids with weak mobility, which assisted TC deposition; besides, providing additional deposition sites for TC by the deposited ferrihydrite colloids was another important mechanism. In contrast, the transport-enhancement effect of montmorillonite on TC was attributed to the strong binding affinity of TC to clay particles as well as the competition between colloids and TC for deposition sites on sand surfaces. Moreover, the transport-inhibition effect of ferrihydrite at pH 7.0 was greater than that at pH 5.0, mainly due to more colloid-associated TC under neutral conditions. Surprisingly, ferrihydrite colloids could act as carriers of antibiotics and enhanced TC transport at pH 9.0. Because the surface charge of colloids was altered to negative and could break through the column. Meanwhile, the transport-enhancement effect of montmorillonite decreased with increasing pH from 5.0 to 9.0, resulting from the decrease of colloid-adsorbed TC. Furthermore, colloid-mediated transport of TC was influenced by ionic strength, which affected the aggregation characteristics of colloids and the binding affinities of TC to minerals. These findings provide critical information for assessing the risks of antibiotics in aquatic ecosystems where abundant natural minerals are present.

Abstract
The sorption of pharmaceuticals and personal care products (PPCPs) on soil and soil components makes an important contribution to the fate, migration and bioavailability of PPCPs. Previous reviews have mostly focused on the sorption of PPCPs on single soil components (e.g., minerals and soil organic matter). However, the sorption of PPCPs within the whole soil system has not been systematically analyzed. This paper reviews the recent progress on PPCP sorption on soil and soil components. We have evaluated the sorption of a wide range of PPCPs in research fields that are usually considered in isolation (e.g., humic acids (HAs), montmorillonite, kaolinite, and goethite), and established a bridge between PPCPs and sorbent. The sorption mechanisms of PPCPs, e.g., cation exchange, surface complexation, electrostatic interaction and hydrogen bonding, are discussed and critically evaluated. We also assessed the influence of environmental factors (pH, ionic strength, organic matter and temperature) on sorption. This review summarizes the knowledge of PPCPs sorption on soil gained in recent years, which can provide new strategies for solving the problem of antibiotic pollution.

Abstract
As a widely used plant growth regulator, the gibberellic acid (GA3) residue in tea has potential risk for human health. Herein, the degradation of GA3 and its conversion into main metabolites were investigated during tea planting, manufacturing, and brewing using ultrahigh-performance liquid chromatography tandem mass spectrometry. The metabolite iso-GA3 was first discovered during the tea production chain and identified using Q-Exactive Orbitrap mass spectrometry. GA3 dissipated following first-order kinetics in tea shoots with half-lives ranging from 2.46 to 2.74 days. It was degraded into iso-GA3 in tea shoots, which had a longer residual period than GA3. Meanwhile, external application of GA3 could increase the proportion of growth-promoting endogenous phytohormones and lead to rapid growth of tea plants. During tea manufacturing, iso-GA3 was quickly and massively converted from GA3. Fixing (heat at 220-230 °C) played an important role in the dissipation of GA3 and iso-GA3 during green tea manufacturing, but there were high residues of iso-GA3 in black tea. High transfer rates (77.3 to 94.5%) of GA3 and iso-GA3 were observed during tea brewing. These results could provide a practical reference for food safety in tea and other agricultural products and the guidance for scientific application of GA3 in tea planting.

Abstract
Chemical oxidation is an effective method to improve the ability of biochars for metals removal, but there are too few studies on screening of high-efficiency oxidants and quantitative analysis of sorption mechanisms. In this study, rape straw biochars (BC) were oxidized with HNO3, H2O2, and KMnO4, and noted as BC-HNO3, BC-H2O2, and BC-Mn, respectively. The Pb removal capacities and quantitative sorption mechanisms of biochars were explored through batch sorption experiments. Compared with that of BC (175 mmol kg-1), the maximum Pb sorption capacities of BC-HNO3 and BC-H2O2 increased to 526 and 917 mmol kg-1, in which contribution of surface complexation accounted for 55.1% and 39.0%, respectively. Due to the large surface area and abundant newly formed MnO2, BC-Mn showed the maximum Pb sorption capacity of 1343 mmol kg-1, and its high removal efficiency appeared even at low pH value (pH = 2) and high initial Pb concentration (1.0 mol L-1). The contribution of cation exchange accounted for 97.4% of the Pb sorption by BC-Mn. These results suggested BC-Mn had great potential for Pb removal from aqueous solution, and the quantitative analyses of sorption mechanisms revealed the contribution of each mechanism and provided a basis for evaluating application prospects of biochars.

Abstract
Nowadays non-steroidal anti-inflammatory drugs (NSAIDs) are often detected in surface water and groundwater. In this study, effects of environmental factors, i.e., solution pH, ionic strength, temperature and surface-bound organic acids, on bonding of three typical NSAIDs (ketoprofen, naproxen and diclofenac) onto goethite were systematically investigated. Column chromatography, batch experiments, attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy and surface complexation modeling were used to probe the adsorption mechanisms. Bonding of three NSAIDs onto goethite was totally reversible, ionic strength-dependent and endothermic (adsorption enthalpy 2.86-9.75 kJ/mol). These evidences supported H-bonding mechanism, which was further explained by ATR-FTIR observation and a triple planes model. Surface-bound organic acids (phthalic acid, trimellitic acid and pyromellitic acid) by inner-sphere complexation with goethite were hard to be desorbed. Surface-bound phthalic acid increased the uptake of NSAIDs but surface-bound trimellitic acid and pyromellitic acid reduced their adsorption. The reason is that the adsorbed phthalic acid can result in a more hydrophobic surface while adsorbed trimellitic acid and pyromellitic acid increased the surface negative charge and polarity. Finally, adsorption of NSAIDs onto goethite with/without surface-bound organic acids was well described by a free energy model, in which contributions of interactions (e.g., H-bonding and van der Waals) were evaluated.
