A comparative study of chemical databases for fine particle Chinese aerosols
Article Abstract:
A chemical database has been put together for PM2.5 and PM2.0 aerosols for various Chinese sites, including Beijing, Tianjin, Wuhan, Lanzhou and Guangzhou. A comparison is drawn between the mass concentration of these Chinese aerosols and that of Los Angeles using scatter diagrams. Various observations were made about the significant changes between the years that measurements were taken, as well as seasonal and regional variations.

Thermodynamic modeling of PCDD/Fs formation in thermal processes
Article Abstract:
The formation of PCDD/Fs (polychlorinated dibenzo-p-dioxins and dibenzofurans) in thermal processes were examined using various models. These models include the Group Additivity approach, Modified Neglect of Diatomic Overlap and Parametrized Model 3, in tandem with the Scientific Group Thermodata Europe database.

General formulation of characteristic time for persistent chemicals in a multimedia environment
Article Abstract:
Researchers have devised a statistical method of testing the persistence of an organic pollutant in the environment. Uses of this method extend beyond the chemical, energy, and agriculture industries to include the government agencies that regulate them. Four approaches were developed. The, lindane, dieldrin, hexachlorobenzene, carbon tetrachloride, cyclohexane, and dioxin were tested using these analytical methods. The chemicals were chosen, as they had been studied by others. So, the method could be compared.
