To determine the best control technology for dioxin in waste incineration flue gas, a three-level comprehensive evaluation index system with environment, economy, and technology as the first-level indexes was constructed. The fuzzy comprehensive evaluation method and the analytic hierarchy process (AHP) were used to evaluate ten dioxin pollution control technologies or technology groups including "double bag activated carbon adsorption technology," "sulfur and sulfide inhibition technology," and "sulfur and sulfide inhibition technology+activated carbon fixed bed reactor technology". The "sulfur and sulfur compound inhibition technology+activated carbon fixed bed technology" scored the highest, and thus is currently the best control technology for dioxin pollution in waste incineration exhaust gas.

Article Synopsis
  • - A whole-cell biosensor called acinetobacter ADP1_pWHlux was genetically engineered for detecting acute toxicity in challenging environments, showing promising results compared to natural luminescent bacteria.
  • - The biosensor effectively demonstrated a dose-response relationship, indicating that its luminescence decreases with higher levels of acute toxins, with a quick response to mercury (HgCl2) and low detection limits for various heavy metals.
  • - The developed biosensor has been successfully tested for detecting acute toxicity in the Qinghe river's water in Beijing, proving its potential for monitoring water quality and contamination.

Article Synopsis
  • Volatile and semi-volatile organic compounds (VOCs/SVOCs) are significant pollutants at industrial sites in China, posing health risks as they can easily escape into the air during excavation activities.
  • A study monitored the concentration of gas-phase VOCs during a site remediation project, finding that their levels decreased with distance and followed a fluctuating pattern downwind.
  • Based on monitoring results, a health and safety zoning method was developed to establish safety measures and personal protection guidelines for workers in different areas of the remediation site.

The dissipative concentration test of VOCs in the remediation process of a typical contaminated site was operated, and three routes of exposure were set up for health risk assessment in the repair process. Analysis showed that carbon tetrachloride was the single pollutant with highest multi-route cumulative non-carcinogenic index, which was as high as 8.86E + 01, and its contribution rate to the integrated non-carcinogenic effects was 74.

Solution 31P-Nuclear Magnetic Resonance (NMR) is an analysis technology which has been an effective means for the analysis of environmental organic phosphorus. However, the method is rarely applied in the study of wetlands so that the corresponding researches about wetland sediment sample preparation method also very deficient. The present study was aimed to find the most suitable sample preparation method for 31P-NMR analysis of the artificial wetland sediments, using different extractant (NaOH or 0.

Article Synopsis
  • The study analyzed soil micro-ecosystems in a coal mining area, focusing on organic pollution levels, physicochemical properties, and microbial characteristics.
  • The organic pollution in the soil ranged from 0.4 to 1.5 mg/g of dry soil, significantly higher than background samples, with pollutants similar to those found in nearby coal gangue.
  • Overall, the presence of pollutants negatively impacted microbial density and activity, with low counts (10^4-10^5 cell/g dry soil) and decreased functions noted, although pH was the only factor that might have supported microbial life.

The microbial communities in oil polluted soils from oilfields of China were analyzed using a modern molecular biological approach. The crude total DNA from soils were directly extracted, 16S rDNA fraction were amplified by PCR, the bands were separated using denaturing gradient gel electrophoresis (DGGE), and some of the typical bands were sequenced and compared with the records of NCBI to classify the germs. Comparison of the DNA extraction indicated that the yields were 1.

Biodegradation efficiency of hydrocarbons and melioration of micro-ecosystem conditions in acid soils should be seriously concerned due to either occurrence of acid polluted soils or acidification during bioremediation process. The influence of acid situation on degrading microbes and the biodegradation rate were figured out by monitoring variations of biomass, microbial activities and petroleum contents with time in acid and alkaline polluted soils in laboratory. Injecting degrading microbes and meliorating micro-ecosystem conditions of acid soils were conducted.

By means of the biostimulation and bioaugmentation in the micro-ecological environment of contaminated soil with petrochemical hydrocarbons, the biodegradation rates and mode of the contaminants were significantly improved. Based on the investigations carried out in some oilfields and petrochemical industrial area of Northern China, the relationship between the abiotic factors such as nutrient, pH, contaminants, water content, alkalinity, etc., and microbial activities was interpreted and identified in this paper.
