Catalytic effects of metal oxides in nonthermal plasma chemical processing of hazardous air pollutants (HAPs) are discussed, relevant to their activities for the oxidation of HAPs in nonthermal plasma media and their selective control of active oxygen species derived from background O2.
MnP and laccases have been applied frequently in various bio-technological processes such as lignocellulosic biomass delignification for ethanol production, oxidation of pollutants, bioremediation processes, textile bio-finishing, beverage processing, bio-bleaching of pulps and detergent manufacturing [ 1- 3, 6- 8].
High on the public's anxiety list are hazardous wastes (especially their disposal) and the transport and use of toxic materials in manufacturing and processing, industrial accidents involving the release of pollutants, the leakage of chemical waste into the soil, and the pollution of water and air from industrial sources.
There are few areas which are important for future development of radiation processing applications: pollutants removal from gaseous and liquid waste, new products and new processes.
However, residence time is an important control on ecosystem processes such as the biotic uptake and processing of excess nutrients and other pollutants in streams.
The major sources of pollutants are from manufacturing processing industries, particularly chemical and textile industries in which organic dyes are widely used.
Electron beam processing is an efficient technology to reduce emissions of pollutants from flue gases of industrial plants.
They are prone to yellowing, mirroring and fading which is largely attributed to the effects of pollutants, relative humidity and residual processing chemicals.
Releases to the environment of pollutants from industrial metal production and processing installations can pose a health problem to humans, owing to the toxic substances that such emissions contain.
Pollutant sampling, processing of samples, analysis and reporting were conducted according to standard operating procedures [ 36].
