Formation mechanisms of trichloromethyl-containing compounds in the terrestrial environment: A critical review
Electrochemical disinfection of groundwater for civil use - An example of an effective endogenous advanced oxidation pro...
Published in Chemosphere
Lab-scale experiments using real groundwater were carried out using the CabECO® reactor system in order to evaluate its suitability for producing safe water, acceptable for civil purposes. Trials were carried out in discontinuous and in continuous mode, analyzing the influence of electrical and hydraulic process parameters on the quality of treated...
Enhanced hexavalent chromium removal performance and stabilization by magnetic iron nanoparticles assisted biochar in aq...
Published in Chemosphere
The superiority of the nanoscale zero valent iron (nZVI) assisted biochar (BC) composites compared to traditional nZVI and its application feasibility are still unclear. This study aimed to provide valuable information for practical application. Firstly, the Fe/BC mass ratio of 2:1 during the preparation of nZVI-BC was proved obtaining the complete...
Supported palladium nanoparticles as highly efficient catalysts for radical production: Support-dependent synergistic ef...
Published in Chemosphere
Supported metallic palladium (Pd) acts as a real catalyst for peroxymonosulfate (PMS) activation to produce highly oxidizing species. However, the species produced are surface-bound in nature, and their use for pollutant degradation requires an inert supporting material to minimize the surface scavenging effect. In this study, we synthesized Pd nan...
LncRNA H19 interacts with S-adenosylhomocysteine hydrolase to regulate LINE-1 Methylation in human lung-derived cells ex...
...Published in Chemosphere
Benzo [a]pyrene (BaP) have been demonstrated to induce lung cancer risk in humans and many different animal models, with aberrant gene methylation as one of the epigenetic errors; however, the molecular mechanisms remain unclear. Here, we used three types of human lung-derived cells with BaP exposure as a model and attempted to investigate the long...
Effects of chemical oxidation on surface oxygen-containing functional groups and adsorption behavior of biochar.
Published in Chemosphere
Biochar is a beneficial soil amendment but the changes in its surface properties during the aging process, especially the oxygen-containing functional groups and the associated adsorption behaviors, are not well documented. In this paper, the aged wheat straw biochar was simulated by chemical oxidation with HNO3-H2SO4 and NaOH-H2O2 systems. Charact...
Toxicity screening of biochar-mineral composites using germination tests.
Published in Chemosphere
This study assessed the properties and toxicity (water cress germination trials) of 38 waste-derived, novel biochar-mineral composites (BMCs) produced via slow pyrolysis and hydrothermal carbonization (hydrochars). The biochars were produced from sewage sludge and compost-like output (CLO) by varying the type of mineral additive (zeolite, wood ash ...
HBCD and TBBPA in human scalp hair: Evidence of internal exposure.
Published in Chemosphere
Human biomonitoring is a reliable method for evaluating human exposure to specific contaminants. Although blood is an ideal matrix for monitoring purposes, it is regarded as an invasive matrix. Therefore, current developments in the field of human biomonitoring are based on introducing new methods that use non-invasive matrices, such as hair. In th...
The different behaviors of glyphosate and AMPA in compost-amended soil.
Published in Chemosphere
The broad-spectrum herbicide glyphosate is one of the most widely used pesticides. Both glyphosate and its major metabolite, aminomethylphosphonic acid (AMPA), persist in waters; thus, their environmental fates are of interest. We investigated the influence of compost dose, sampling depth, moisture and saturated hydraulic conductivity (Ks) on the p...
Roles of intrinsic Mn3+ sites and lattice oxygen in mechanochemical debromination and mineralization of decabromodipheny...
Published in Chemosphere
Commercial β-MnO2 with a chemical formula of approximate Mn0.774+Mn0.233+O1.88 was used for mechanochemical (MC) oxidative degradation of decabromodiphenyl ether (BDE209). The ball milling process initiated the degradation of BDE209 on β-MnO2, yielding a nearly complete degradation and debromination of BDE209 within 2 h. The use of β-MnO2 exhibited...
