Photocatalytic wastewater treatment combined with ozone pretreatment
Article Abstract:
The photocatalytic process as a new wastewater treatment method is discussed. Photocatalytic degradation experiments were carried out to probe the mineralization time lag that stable compounds exhibit. In particular, fenitrothion was degraded by ozonation and photocatalytic treatment in the experiments. It was found that the degradation of pollutants is greatly facilitated by ozonation pretreatment prior to photocatalytic treatment and that the effect of ozone pretreatment is not confined to aromatic compounds.

Hydrocarbon wastes at petroleum- and creosote-contaminated sites: rapid characterization of component classes by thin-layer chromatography with flame ionization detection
Article Abstract:
Soil extracts from contaminated petroleum and creosote wood preserving sites were subjected to rapid analysis by thin layer chromatography with flame ionization detection (TLC-FID). Two mobile-phase systems solvent extracted and characterized the residues of soils collected from an abandoned oilfield battery site and a former creosote wood treatment facility. It was found that a rapid, semiquantitative characterization of heavy hydrocarbon residue extracts according to component type is provided by TLC-FID.

Flux of detergent-derived pollutants to Tokyo Bay
Article Abstract:
The inputs of two detergent-derived pollutants to the seasonal variation and modes of riverine input of organic pollutants to the coastal zone were discussed. The Tamagawa River was subjected to site description and sampling methods. The presence of alkylbenzenes, linear alkylbenzenesulfonates and carbon content were analyzed in all samples. It was found that seasonal variations of organic pollutant input were based on microbial degradation activity.
