Recent Trends in Sampling and Assessment of Stack Effluents

An important problem associated with air pollution control is to obtain a representative sample and to analyse it properly. The sampling techniques of stack effluents (gases as well as particulates) are still unexplored fully. A continuous analysis of the stack effluents is desirable in order to control pollution of the air effectively and efficiently.
The present state of knowledge in this vital field of sampling and analysis of stack effluents along with some critical comments forms the basis of this paper. This field is particularly challenging to the manufacture of equipment for sampling and assessing pollutants.
