Ozonation of 14 C-labeled micropollutants - mineralization of labeled moieties and adsorption of transformation products to activated carbon.

Most known products that are produced during micropollutant ozonation are unknown, and it is unknown to what extent these compounds can be removed by subsequent adsorption to activated carbon. Based on the adsorption of the labeled carbon, 14 C-labeled micropolutants were ozonated to produce 14 C-labeled OTPs, for which the adsorption of the sum of all 14 C-labeled OTPs to activated carbon could be determined. Bisphenol A, sulfamethoxazole, and sulfadiazine were both identified in the formation of 14 CO 2 by an aromatic ring cleavage. Following ozonation, which was related to a decreased adsorption of dissolved organic matter, increased adsorption of micropollutants to powdered activated carbon, according to the adsorption of dissolved organic matter in adsorption. These results show that adsorption to activated carbon alone is not a viable removal method for a wide variety of ozonation transformation products.

14 year applications of chemical fertilizers and crop straw effects on soil labile organic carbon fractions, enzyme activities and microbial community in rice-wheat rotation of middle China.

Traditional fertilization management can jeopardize soil stability and result in significant soil erosion. Crop straw returning to the field reduces the negative effects of straw burning and improves soil quality, improving soil quality. Organic carbon, microbial biomass carbon, particulate organic carbon, and easily oxidized organic carbon concentrations by 79. 32 percent, 92. 46 percent, and 104. 32 percent relative to CK, increased the dissolved organic carbon, microbial biomass carbon, particulate organic carbon, and readily oxidized organic carbon concentrations by 79. 32 percent, 82. 36 percent, 96. 32 percent, 96. 32 percent, 104. 32 percent, According to soil microbial community diversity and richness, as well as improved microbial activity, which is also helpful in soil erosion degradation, which is beneficial in soil degradation. Following straw returning, we discovered that soil fungi were more sensitive than bacteria to shifts in soil carbon composition and enzyme activity.
