EDTA often remains in the washed soil and impacts the effectiveness and mobility of toxic metals. Therefore, the residual EDTA in soil after remediation, especially their forms and lability, should be paid more attention. Many previous studies have studied EDTA adsorption behavior on the water-mineral interface in the EDTA solution system, or single metal-EDTA chelate system, where [metal]: [EDEA] = 1:1. However, the stoichiometrically excessive chelating agent is generally used in soil washing practices, where the free EDTA and metal-EDTA chelates coexist. In this study, the EDTA and metal-EDTA chelates kinetic distribution on goethite mineral surface at pH 5.5 or 8, respectively, at EDTA: Ni: Cd = 2:1:1 (EDTA equivalent) or 5:1:1 (stoichiometrically excessive EDTA) was studied. The adsorption kinetics of Cd-EDTA, Ni-EDTA and EDTA on goethite were stimulated by the genetic algorithm. The adsorption rate constants of free EDTA, CdEDTA 2- and NiEDTA 2- on goethite are 10 -0.58 , 10 -2.15 and 10 -2.46 respectively, indicating free EDTA can be adsorbed on goethite two orders of magnitude faster than CdEDTA 2- and NiEDTA 2- with the same dosage. Because of much easier of Fe to replace Cd than Ni in chelates, the dissolution rate constants of adsorbed Cd-EDTA and Ni-EDTA on goethite are 10 -2.41 and 10 -4.51 , respectively, suggesting the subsequent dissolution of Fe(OH) 3 is mainly induced by Cd-EDTA rather than Ni-EDTA. Therefore, the mineral dissolution induced by the residual EDTA after washing and the associated environmental risks should not be ignored. © 2022, The Authors. All rights reserved.

Nitrate (NO3-) is a major component of atmospheric fine particles. Recent studies have reported the increasing trend of NO3- in contrast to the ongoing control of nitrogen oxides (NOx) in eastern China. Here, we elucidate the effects of the reduction in sulfur dioxide (SO2) on the enhancement of NO3- formation based on field measurements at the summit of Mt. Tai (1534 m a.s.l) and detailed modelling analyses. From 2007 to 2018, the measured springtime concentrations of various primary pollutants and fine sulfate (SO42-) dropped sharply (-16.4% – -89.7%), while fine NO3- concentration increased by 22.8%. The elevated NO3- cannot be explained by the changes in meteorological conditions or other related parameters, but was largely attributed to the large reduction in SO42- (-73.4%). Results from a multi-phase chemical box model indicate that the reduced SO42- decreased the aerosol acidity and thus prompted the partitioning of HNO3 into the aerosol phase. WRF-Chem model analyses suggest that such a negative effect is a regional phenomenon throughout the planetary boundary layer over eastern China. This study provides new insights into the worsening situation of NO3- aerosol pollution and has important implications for haze pollution control in China. © 2023, The Authors. All rights reserved.

Landfill as a major reservoir of organohalide pollutants provides a unique niche for selective enrichment of organohalide-respiring bacteria (OHRB), playing a critical role in cycling of anthropogenic organohalides in natural environments. Nonetheless, information on the landfill-derived OHRB and associated microbial interactions for microbial reductive dehalogenation remains unknown. In this study, dehalogenation microcosms were established with nationwide landfill leachate samples collected from 45 cities in China, which dechlorinated a common anthropogenic organohalide - tetrachloroethene - to chloroethenes in varied extent. Both the 16S rRNA gene amplicon-sequencing and metagenomics analyses suggested critical roles of unknown Dehalococcoidia and phylogenetically-diverse facultative OHRB in microbial reductive dehalogenation in landfills. Further culture-based interaction examination showed a complicated metabolic network among OHRB, sulfate-reducing bacteria, fermenting bacteria and methanogenic archaea. Particularly, the acetate competition between obligate/facultative OHRB and methanogens were shown to have a threshold concentration of 0.06/0.20 mM, above which the methanogenic Methanosarcina became more competitive, in contrast to the dominance of acetotrophy of obligate/facultative OHRB under the threshold concentration. Accordingly, the Methanosarcina and OHRB preferred acetate transfer from fermenting Clostridium and sulfate-reducing Desulfovibrio, respectively, which was determined by the "Maximum Power Principle" to maximize ecological fitness through optimizing energy utilization efficiency. This study provided the first insight into landfill-derived OHRB and their metabolic interactions with associated functional microorganisms, which could support future bioremediation of organohalide-contaminated landfills.

Perfluoro-2-propoxypropanoic acid ammonium salt (known as GenX) is a persistent, bioaccumulative, and toxic synthetic organofluorine compound used to manufacture numerous products. It is raising concern because of its widespread occurrence in the aquatic environment and its refractoriness to conventional water treatment techniques. In the present study, effective adsorption of GenX was obtained using chitosan (CS) modified adsorbent. Cross-linked and aminated CS beads were synthesized using 1,2:7,8-diepoxyoctane (DEO) and 3-aminopropyl triethoxysilane (APTES). Such CS-DEO-APTES adsorbent shows an adsorption capacity (825.9 mg/g) that was 2.26 times higher than that of CS beads (364.6 mg/g), owing to its enrichment in amino groups. Moreover, it could stably work under acidic conditions (optimal pH=4) thanks to cross-linking. Kinetic data (which followed the pseudo-second-order rate) and isothermal ones (best-fitted by the Langmuir model) indicated that interactions between GenX and CS-DEO-APTES were of chemisorptive nature, and adsorption sites were almost uniform. GenX-saturated beads were successfully regenerated (for at least 6 cycles) using 1% w/v aqueous NaCl and methanol (30:70% v/v). Density functional theory (DFT) calculations indicated that the adsorption of GenX is mainly affected by electrostatic interactions. In sum, CS-DEO-APTES adsorbent is a valid option for GenX removal from aqueous solutions. © 2023, The Authors. All rights reserved.

Industrial emissions are a significant contributor to volatile organic compound (VOC) pollution. However, timely and accurate tracking of high-emitting plants within industrial parks remains a challenge. Here, we deployed three high-density VOC sensor networks across a package printing industrial park (103 sites/km 2 ), a fine chemical industrial park (8.57 sites/km 2 ), and an urban area in central China. These networks enabled the identification of VOC pollution characteristics and sources in these regions. The average VOC concentrations in the package printing industrial park (320 ± 262 ppb) and the fine chemical industrial park (155 ± 62 ppb) were 1.62 to 2.75 times and 1.27 to 1.70 times higher compared to the urban area. pollution levels in these two industrial parks were more severe than those reported in other industrial parks, primarily due to the higher VOC emission factors or higher VOC emission fluxes associated with these industries. Importantly by integrating VOC concentration contour maps with meteorological data, three major polluting plants in the package printing industrial park and three in the fine chemical industrial park were identified. These findings were further validated through downwind tracing of VOC species using gas chromatography-mass spectrometry. These results highlight that a VOC sensor network is an effective tool for real-time monitoring of VOC variations and the precise identification of high-pollution plants across various industrial parks. This approach can provide valuable insights for the control and management of VOC pollution.
