In order to investigate the air quality and the abatement of traffic-related pollution during the 2008 Olympic Games, we select 12 avenues in the urban area of Beijing to calculate the concentrations of PM10, CO, NO2 and O3 before and during the Olympic traffic controlling days, with the OSPM model.
This study explores a bibliometric approach to quantitatively assessing current research trends on volatile organic compounds, by using the related literature in the Science Citation Index (SCI) database from 1992 to 2007. The articles acquired from such literature were concentrated on the general analysis by scientific output, the research performances by countries, institutes, and collaborations, and the research trends by the frequency of author keywords, words in title, words in abstract, and keywords plus. Over the past years, there had been a notable growth trend in publication outputs, along with more participation and collaboration of countries and institutes. Research collaborative papers had shifted from the national inter-institutional to the international collaboration. Benzene, toluene, and formaldehyde were the three kinds of VOCs concerned mostly. Detection and removing, especially by adsorption and oxidation, of VOCs were to be the orientation of all VOCs research in the next few years.
Microorganisms capable of degrading Di-n-Butyl Phthalate (DBP) were isolated by acclimation and enrichment techniques. The adaptation of microorganisms to DBP was investigated. The microbial cells were immobilised onto the ceramic honeycomb supports. The DBP degradation was performed in a novel kind of bioreactor using ceramic honeycomb support as carrier for microbial immobilisation. The experimental results showed that the biomass adsorbed onto the ceramic support could reach 95 mg dry weight/g carrier. The immobilised microbial cells were used for the treatment of wastewater containing DBP. The results demonstrated that the DBP concentration of the outlet reached the stationery-state level of less than 1.0 mg/L within three days at inlet DBP concentration of 100 mg/L and 12 h of hydraulic retention time.
