We revise the Carbon Bond chemical mechanism to explicitly represent three Stabilized Criegee Intermediates (SCIs) and their subsequent reactions with sulfur dioxide, water monomer, and water dimer, and incorporate the reactions into the Community Multiscale Air Quality model. The reaction of sulfur dioxide with SCI produces sulfuric acid which partitions into sulfate. We examine the impact of sulfur...
In order to reveal effect mechanism of crop reactive oxygen species (ROS) metabolic system under exogenous salicylic acid (SA) to ozone (O3) stress, open top chambers were utilized to investigate the change of ROS production rate, lipid peroxidation extent, anti-oxidative enzymes activities and antioxidant content in soybean (Glycine max.) leaves. Exogenous SA treatment relieves the aggravation of...
Ozonation of dimethylamine (DMA), the most direct and common precursor of high carcinogenic disinfection by-product N-nitrosodimethylamine (NDMA), in aqueous solutions and in the presence of H2O2 was studied at ozone doses of 1.8 mg/L. The removal ratio of DMA increases from 46.7% to 77.1% with the dosage of H2O2 increasing from 0 to 1 mM, and the removal rate can be improved by increasing pH. According...
Chironomus kiiensis larvae which cannot be exterminated by conventional disinfection process propagates prolifically in eutrophic water body, and it therefore turns to be a potential problem encountered in drinking water quality. In this paper, the quantitative experimental studies were carried out on inactivation of the fourth instar larvae of Chironomus kiiensis in the raw water using oxidants,...
Chironomus kiiensis larvae which cannot be exterminated by conventional disinfection process propagates prolifically in eutrophic water body, and it therefore turns to be a potential problem encountered in drinking water quality. In this paper, comparative experiments on the inactivation of the fourth instar larvae of Chironomus kiiensis in distilled water by chlorine, ozone and chlorine were conducted...
Using dimethyl phthalate (DMP) as a phthalic acid esters (PAEs) probe, two candidate processes, ozonation (O3) and O3 combined with ultraviolet radiation (O3/UV), were evaluated for their efficiency in removing DMP and mineralizing the degradation products. The DMP degradation intermediates and final products were determined by capillary electrophoresis (CE). The results showed that the removal of...
