PISCES: Power industry integrated systems, chemical emissions study

Power industry chemical emissions study (PISCES) is a broad based study con ducted by EPRI in the USA with input from utilities in the USA and other pa rts of the world. It aims to define the source, distribution, composition a nd fate of toxics in power plant process and waste streams. Eskom is partak ing in this project to develop knowledge of trace element emissions from th e power stations which will provide Eskom with sufficient information to de termine the concentration levels of toxic trace element emissions from the power stations. From this, the fate of these emissions and their impacts on the environment can be determined. This paper is a report on the first sam pling project conducted in South Africa at one of Eskom's power stations. T he total study will involve sampling at other power stations and a risk ana lysis of the fate of the toxic elements emitted. This total study will be c ompleted in 1999.
